Now, a friend of mine showed me how to build the IT++ library with Cmake from the comand line in Windows. Create a 'build' directory in the directory for your downloaded version 4.3.1 if IT++, the current latest version. Open the Visual Studio Developers Command line tool (or the Visual Studio Command line tool) from within Visual Studio (2022). Go to your creaated build directory. Make the commands: cmake .. cmake --build . For me this creates an IT++ library in build\itpp\Debug\itpp.lib However,...

I have now tested the (static) 64bit It++ library I was able to build according to my posts above. I tested the Matlab mex example at the bottom of the page https://itpp.sourceforge.net/4.3.1/group__mexfiles.html that I put in a C++ file named itpp_qpsk_modulation_mex_function.cpp. In the same directory I also placed a copy of the 'itpp' directory containing the heared files, and your compiled 64 bit IT++ library which to my understanding you need when you use a 'modern' 64 bit Matlab version. This...

FYI. Why would one need to compile in 64 bits? Well, if one would like to use IT++ in a Matlab mex file from a 64 bit Matlab: "MathWorks Support Team on 27 Jun 2009 0 Link The ability to compile 64-bit MEX-files that access functions in 32-bit DLL's is not available in MATLAB. 64-bit applications such as 64-bit MATLAB can only use 64-bit shared libraries. In general, you cannot mix 32-bit and 64-bit code in a single application. If you have a 64-bit application, everything related to that application,...

Bogdan, Thanks for the information. I will study it further. For whatever reason I am at the moment running into trouble when I set ITT_SHARED_LIB to 'on' (i.e. checking it in the Windows CMake GUI), so I am setting it to 'off' (i.e. unchecking it in the Windows CMake GUI). I was able to this way build, presumably, a static library, in 64 bit debug mode, even though it became suspiciously large, 523 MB . When I switch to build it in release mode I had add the line: #define HAVE_LOG2 1 in config_msvc.h...

Compilation errors when trying to build the static library on Windows
-
Hi Erik IT++ has not been updated for quite some time, but should still be compatible with VS 2022. For the best results, you should follow this page: https://itpp.sourceforge.net/4.3.1/installation.html and use the default options when generating from cmake the VS solution, i.e. ITPP_SHARED_LIB=ON The above option generates the shared library (DLL): itpp.dll (and the associated .lib file) into ${CMAKE_BUILD_DIR}/itpp/Debug folder (assuming you generate the debug build). The compilation warnings...
-
How about that. By changing ITPP_SHARED_LIB to 'off' in CMake I was able to get the code to build. (I guess this builds a static library?) I do however get a lot of warnings of this type: warning C4273: 'tgamma': inconsistent dll linkage Not sure if one need to pay attention to these warning messages. Also, I have not yet tested that this library works. Further, the file with the library, itpp_debug.lib (64 bit debug without usage of BLAS and LAPACK and such) becomes VERY big, 532 MB. That seems...

A related issue, possibly the cause of the problem I am experiencing, seems to be that neither itpp_EXPORTS nor itpp_debug_EXPORTS seems to be defined when they are used in itexports.h but it seems one of them need to be set in order to define ITPP_EXPORT __declspec(dllexport) in itexports.h such as not to get many compilation errors of this type: error C2491: 'itpp::Normal_RNG::ktab': definition of dllimport static data member not allowed Now, according to the code, itpp_EXPORTS and itpp_debug_EXPORTS...

Add cmake options to include only specified modules in the library

Hi This option is not yet available when using cmake. You could try to change itpp/CMakeLists.txt file https://sourceforge.net/p/itpp/git/ci/master/tree/itpp/CMakeLists.txt by commenting the sources you don't want to be included, e.g., file ( GLOB ITPP_SRCS "base/*.cpp" "base/algebra/*.cpp" "base/bessel/*.cpp" "base/math/*.cpp" "comm/*.cpp" "fixed/*.cpp" "optim/*.cpp" # "protocol/*.cpp" # "signal/*.cpp" "srccode/*.cpp" "stat/*.cpp" ) regards Bogdan

Hello, I am using the IT++ library in a baremetal environment with limited memory. I am linking the library statically and the resulting binary turns out to be very large. I was wondering if there is a way to only compile and link a specific subset of the library. For instance, I would like to compile and link the "Basic Mathematical Feature" and the "Communication" part. I do not need the other parts of the library. Thanks for any hint. G

I was able to successfully compile IT++ by replacing line 439 of the file srccode/audiofile.cpp std::streamsize ann_length = (std::streamsize)std::min(hdr_size - snd_fixed_header_size, max_annotation_length); with this std::streamsize ann_length = (std::streamsize)std::min((uint32_t)(hdr_size - snd_fixed_header_size), (uint32_t)max_annotation_length); Essentially casting the arguments of the function min into uint32_t One last issue is bothering me.

Hi, I am using Block LDPC codes to encode and decode WiGig packets. To do that, I generate parity-check matrix from a base- matrix. Then, I pass the generated parity-check matrix to Block LDPC generator BLDPC_Generator which in turn is passed to the LDPC_Code object. Based on the online documentation, the -1 in the base-check matrix presents submatrices with all zero entries. Here is a snippet of my code: imat codeMatrix = "40 -1 38 -1 13 -1 5 -1 18 -1 -1 -1 -1 -1 -1 -1;" "34 -1 35 -1 27 -1 -1 30...

So if I use the BLDPC _Generator class directly to generate the enocded codeword and just use the LDPC_Code to decode the received codeword i.e. without passing the generator, the code works. However, it seems there are always errors in the decoded codeword even if I use a noiseless channel. So probably that is why perform_integrity_check fails? Here is my code: #include <itpp/itcomm.h> using namespace std; using namespace itpp; int main (int argc, char *argv[]) { imat codeMatrix = "40 -1 38 -1 13...

Hi Bogdan, I think there are no issues or dependencies in the external blas library which im trying to link with. The below simple example provides me the same result as i see while cross compiling with external library. I downloaded netlib's blas and built libblas.a using native gcc make. Similarly, built libcblas.a using gcc make and linked it with libblas.a .Further i built libitpp_static.a using "cmake .. -DITPP_SHARED_LIB=off -DBLA_STATIC=on -DBLAS_LIBRARIES=<xxx>/CBLAS/lib/libcblas.a" make...
-
Hi That message is a warning, BLAS library might not expose that specific function, this however does not impact the library functionality, probably only the processing time. Bogdan
-
Hi Bogdan, i will try to recompile the blas library which im trying to link with for the arm and test it again to check there are no dependencies in the library. Meanwhile when i run cmake, im getting some library(cheev_) not found error, once the BLAS API detected . Is this gives any clue? -- A library with BLAS API found. -- A library with BLAS API found. -- Looking for cheev_ -- Looking for cheev_ - not found Regards, Heera

Hi Heera Your message above says that there are compile time errors about missing dependences. So what are these errors specifically ? Bogdan

Hi Bogdan, Thank you for your response. I already verified that the CMake is referring the specified static libraries correctly and i don't have any other shared libraries to link. Regards, Heera

Update MKL support
-
Thanks for reporting this, I'll create a bug report
-
Thanks Bodgan, I've posted my question on Intel MKL Forum. I wanted to see if anyone had expereinced the same problem with the latest MKL. What you mentioned regaeding IT++ not optimally using MKL API makes sense as ITPP is not being updated and Intel MKL has been quite modified since the last stable release of IT++. One of the issues that I ran into during linking with MKL is that one of the domains is outdated by MKL. So instead of using MKL_FFT in ITPP, you have to use MKL_DOMAIN_FFT.
-
Hi This is a question you should address in MKL forums. One possible reason could be that IT++ is not using optimally the MKL API, but you should try to track down this problem to a specific call to be sure. regards Bogdan
-
Hi You are using the correct variabled for specifying the libraries, LAPACK_LIBRARIRES and BLAS_LIBRARIES. Try the following: - when you cross-compile use make VERBOSE=1 and check if the library is compiled using the correct BLAS/LAPACK libraries - make sure that when you compile using the static IT++ library you also add the shared libraries (if any) needed by IT++ regards Bogdan

Hi, I've written a PHY stack that encodes and decodes 802.11 frames using the ITPP library. Now I am doing some performance evaluation for my implementation and trying different optimization options to speed up calculations and execution time.

However, when I switch to the latest version of Intel MKL, the execution time increases to 210 seconds which is not expected. These...

Replace AMD Core Math Library (ACML) with AMD Optimizing CPU Libraries (AOCL)

Hi IT++ depends on several external libraries in order to speed up calculations: FFTW, Lapack, Blas. You can either find these libraries compiled for your mobile platform or try to compile IT++ without these libraries (probably some speed penality will occur). Besides external dependences, since IT++ library is written in C++ and uses cmake as compilation management system, it can be crosscompiled on other platforms (e.g. Android, iOS) using toolchain files (https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html)....

In MinGW, $LIB returns the following: $ $LIB sh: C:\IntelSWTools\compilers_and_libraries_2019.4.245\windows\mkl\lib\intel64_win: is a directory then I invoke the following command as given in this guide: http://itpp.sourceforge.net/4.3.0/installation.html cmake .. -G "MSYS Makefiles" -DBLA_VENDOR=Intel11 -DCMAKE_INSTALL_PREFIX="C:\ITPP" But it is unable...

Thank you sir, But sir, I have used sudo apt install libitpp-dev Now it did not show error but it showed lot of warning. I will analyse cmake logs if "sudo apt install libitpp-dev" fails in the future Thanks for the suggestion, sir.

Hi Check cmake logs in order to learn why FindITPP.cmake failed. regards Bogdan

Sir / Madam, I am new to both GNU and ITPP, I am trying to run gr-ofdm example from CGRAN in my ubuntu 16.04 system. I have installed all prerequisites as mentioned in CGRAN. I have installed ITPP too. But it is showing error as shown in the attached file. i.e: CMake Error at cmake/Modules/FindITPP.cmake:46 (MESSAGE): Could not find ITPP library Call Stack (most recent call first) CMakeLists.txt:117 (find_package) I have followed step by step instructions mentioned in the site http://itpp.sourceforge.net/4.3.1/installation.html....

Hi This is a draft paper that explains the algorithms implemented in IT++ for indoor localisation. Check the bibliography for references: https://www.researchgate.net/profile/Bogdan_Cristea/publication/311695923_Hybrid_Multilateration_for_Indoor_Localization/links/58552c0908ae81995eb3f2f9/Hybrid-Multilateration-for-Indoor-Localization.pdf regards Bogdan

Hi everybody, I'm using itpp multilateration (defined in itpp/comm/multilateration.h) with spherical setting, using only TOAs. It works very well in 3D setting, being very precise. I wanted to modify the algorithm in order to compute spherical localization in 2D environment. The algorithm in itpp doesn't work as if you use it with beacons all on the same plane the algorithm detects their coplanarity. Could someone give me some hint in order to modify the algorithm for my purpose? Specifically I'd...

Done, working fine at last. Many many thanks. Regards.

you need to set the library search path to the location where libitpp.so is installed: use either LD_LIBRARY_PATH or ldconfig application

Hi, I am sorry for bothering again. I am getting exactly the same error message. I have done all the steps in the thread. I don't get any compilation errors but I get the error when I execute the output file: error while loading shared libraries: libitpp.so.8: cannot open shared object file: No such file or directory I tried both commands, and I get the same error message with both. g++ exp_itpp.cpp -I$ITPP_HOME/include -L$ITPP_HOME/lib -litpp g++ itpp-config --cflags -o example exp_itpp.cpp itpp-config...

Worked smoothly. Thanks a lot. Have a great evening.

Hi Here are the steps I have used: git clone ssh://<user>@git.code.sf.net/p/itpp/git itpp-git git clone https://github.com/google/googletest.git cmake .. -DGTEST_DIR=$HOME/projects/googletest/googletest Note that GTEST_DIR does not point to the sources root folder (when googletest is cloned with git) but goes one level lower where only googletest sources are. In order to run the tests use (from build folder) ./gtests/itpp_gtests
-
Could you please send me the link? I downloaded it from github but I am still getting the same error message. Many thanks. Regards.
-
Hi gtest sources need to be downloaded separately in your gtests folder before you start the actual compilation. regards Bogdan
-
After downloading this revesion it managed to build, however, when I am not able to do the testing. cmake .. -DGTEST_DIR=/home/shahein/Downloads/itpp-git/gtests -- A library with BLAS API found. -- A library with BLAS API found. -- A library with LAPACK API found. -- A library with FFT API found. CMake Warning (dev) at cmake/Modules/CheckCXXFunctionExists.cmake:32 (IF): Policy CMP0054 is not set: Only interpret if() arguments as variables or keywords when unquoted. Run "cmake --help-policy CMP0054"...

Hi The above change should be made in case IT++ compilation gives an error. If you have an error either you change random_dsfmt.h file or checkout with git the master branch. If no error nothing should be done. regards Bogdan

Alireza Sheikh posted a comment on discussion Help
Hi again, Do you mean that I should add the above code in the random_dsfmt.h? or delete the IT++ package I have downloaded and download it again? I do not know what do you mean by master branch.
