Dear changtsan, first: Please do not write directly to the responder but to the mailing list so that everyone can read your further questions. (Usually you set the responder as CC, if you wish to.) Concerning your question: It's better to link the library when building the exe: g++ -L/home/changtsl/lapackpp_lib/lib -llapackpp main.o -o main.exe So you should delete the second g++-line in your makefile and change the third to the one above.

Hi Dominik, Thank you very much. I try to follow your indication, so now the content of my makefile now is g++ -c -I/home/changtsl/lapackpp_lib/include/lapackpp main.cpp g++ -L/home/changtsl/lapackpp_lib/lib -llapackpp main.o -o main.exe I think the file "main.o" and "main.exe" are produced successfully. But when I execut "main.exe", the error message shows [changtsl@cee-changtsl EIG]$ ./main.exe ./main.exe: error while loading shared libraries: liblapackpp.so.14: cannot open shared object file: No such file or directory What should I do then? Thank you very much.

Dear changtsan, You link lapackpp-Library dynamically to your main.exe. This means everybody who wants to start main.exe needs to have the lapackpp-Lib somewhere in his execution path. The easiest way tol solve this is to copy the library in the same directory as the exe. Then the programm should execute fine.

Dear changtsan, please do start the command from the command line itself: $ ./makefile $ LD_LIBRARY_PATH=/home/changtsl/lapackpp_lib/lib ./main.exe Usually you do not start a programm with a real makefile. (But of course you do not have a real Makefile.) If this doesn't work, you could display what libraries are searched for and where they are found: $ ldd main.exe Further please list the content of the lib-folder: $ ls /home/changtsl/lapackpp_lib/lib With regards Dominik -------- Original-Nachricht -------- Betreff: Re: [Lapackpp-devel] question of including lapack++ in my makefile Von: Abraham Chang-Tsan Lu <cha...@cm...> An: lap...@li...

Dear Dominik,
I try what you indicate, it works on my machine! However, the following
shows that main.exe cannot find liblapackpp.so.14.
[changtsl@cee-changtsl EIG]$ ldd main.exe
linux-vdso.so.1 => (0x00007fff2e7fd000)
liblapackpp.so.14 => not found
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x000000375a400000)
libm.so.6 => /lib64/libm.so.6 (0x0000003753c00000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000003759c00000)
libc.so.6 => /lib64/libc.so.6 (0x0000003753800000)
/lib64/ld-linux-x86-64.so.2 (0x0000003753400000)
But when listing the content of /lib, it is obvious that
"liblapackpp.so.14" exists. "liblapackpp.so.14" is actually a link to
"liblapackpp.so.14.2.0".
[changtsl@cee-changtsl EIG]$ ls /home/changtsl/lapackpp_lib/lib
liblapackpp.la liblapackpp.so.14 pkgconfig
liblapackpp.so liblapackpp.so.14.2.0
How come main.exe cannot find "liblapackpp.so.14"?
I try the same thing on another machine where lapackpp is located in
/usr/local/packages/lapackpp
by
$ g++ -c -I/usr/local/packages/lapackpp/include/lapackpp main.cpp
$ g++ -L/usr/local/packages/lapackpp/lib -llapackpp main.o -o main.exe
$ LD_LIBRARY_PATH=/usr/local/packages/lapackpp/lib ./main.exe
then it shows
./main.exe: error while loading shared libraries: libmkl_intel_ilp64.so:
cannot open shared object file: No such file or directory
The libraries that main.exe can search are
linux-vdso.so.1 => (0x00007fff6f9ff000)
liblapackpp.so.14 => not found
libstdc++.so.6 => /usr/X11R6/lib64/libstdc++.so.6 (0x00007ffa83942000)
libm.so.6 => /lib64/libm.so.6 (0x00007ffa836ec000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007ffa834d5000)
libc.so.6 => /lib64/libc.so.6 (0x00007ffa83177000)
/lib64/ld-linux-x86-64.so.2 (0x00007ffa83c4d000)
I am wondering, on both machines, "liblapackpp.so.14" indeed exists in the
appropriate directories, but the "main.exe"s cannot find it out?
I am also wondering why the "LD_LIBRARY_PATH=" command works on my own
machine but doesn't work on the other machine?
Thank you very much.
Sincerely,
changtsan

Dear changtsan,
please do start the command from the command line itself:
$ ./makefile
$ LD_LIBRARY_PATH=/home/changtsl/lapackpp_lib/lib ./main.exe
Usually you do not start a programm with a real makefile. (But of course
you do not have a real Makefile.)
If this doesn't work, you could display what libraries are searched for
and where they are found:
$ ldd main.exe
Further please list the content of the lib-folder:
$ ls /home/changtsl/lapackpp_lib/lib
With regards
Dominik

Dear changtsan, the path in the makefile (behind the -L) is not important for the execution of the program. But because of the "exe" I thought you are using Windows. But as I see now you use Linux or something like it. So you need to tell the application where the library is located because Linux does not search in the current directory as default (and you shouldn't change it for security reasons). There are some ways to solve this problem. See http://www.eyrie.org/~eagle/notes/rpath.html for example in using the "-R" option when linking the binary (the line with the -L in it): g++ -R/home/changtsl/lapackpp_lib/lib -L/home/changtsl/lapackpp_lib/lib -llapackpp main.o -o main.exe But pay attention, that the main.exe will only work on your system (or at least on any system that has the library in this path or in the global path defined by LD_LIBRARY_PATH). So you could also link the main.exe via g++ -R. -L/home/changtsl/lapackpp_lib/lib -llapackpp main.o -o main.exe so the library will first be searched in the local directory. (You need to copy the so-files in the same directory as the main.exe of course.)

Dear Dominik, I really appreciate your help. I follow what you indicated, it shows [changtsl@cee-changtsl EIG]$ ./makefile g++: unrecognized option '-R/home/changtsl/lapackpp_lib/lib' Wed Nov 16 13:24:07 EST 2011 ./main.exe: error while loading shared libraries: liblapackpp.so.14: cannot open shared object file: No such file or directory finished and [changtsl@cee-changtsl EIG]$ ./makefile g++: unrecognized option '-R.'

The OS on my machine is RedHat linux. Thank you.

Dear changtsan, The "not found" indicates that liblapackpp.so.14 is not in the default library path defined by LD_LIBRARY_PATH. If you call "ldd" with the PATH-variable set before it should find it. The same is true for the other machine. The folder /usr/local/packages/lapackpp is usually not in the path. You can see the path via $ echo $LD_LIBRARY_PATH If you want to start main.exe on the other machine you should do: $ LD_LIBRARY_PATH=/usr/local/packages/lapackpp:$LD_LIBRARY_PATH ./main.exe (I forgot the :$LD_LIBRARY_PATH above, even if it works for you.) The other solution is to extend LD_LIBRARY_PATH in the .bashrc, see http://www.warp1337.com/content/ubuntu-910-extend-set-configure-ldlibrarypath-path-howto With regards Dominik -------- Original-Nachricht -------- Betreff: Re: [Lapackpp-devel] question of including lapack++ in my makefile Von: Abraham Chang-Tsan Lu <cha...@cm...> An: lap...@li...

Dear Dominik, The information you provided works on both machines. I deeply appreciate your kindly help. Thank you very much! Sincerely, changtsan On Wed, November 16, 2011 23:51, Dee wrote: Dear changtsan, The "not found" indicates that liblapackpp.so.14 is not in the default library path defined by LD_LIBRARY_PATH. If you call "ldd" with the PATH-variable set before it should find it. The same is true for the other machine. The folder /usr/local/packages/lapackpp is usually not in the path. You can see the path via $ echo $LD_LIBRARY_PATH If you want to start main.exe on the other machine you should do: $ LD_LIBRARY_PATH=/usr/local/packages/lapackpp:$LD_LIBRARY_PATH ./main.exe (I forgot the :$LD_LIBRARY_PATH above, even if it works for you.) The other solution is to extend LD_LIBRARY_PATH in the .bashrc, see http://www.warp1337.com/content/ubuntu-910-extend-set-configure-ldlibrarypath-path-howto With regards Dominik -------- Original-Nachricht -------- Betreff: Re: [Lapackpp-devel] question of including lapack++ in my makefile Von: Abraham Chang-Tsan Lu <cha...@cm...> An: lap...@li...
