install itpp over eclipse

[marco govoni]

Hi,

I'm very new in ubuntu, eclipse and itpp world.
I'm trying to install itpp and debugs the cpp file in eclipse.

In wikipedia there are two command line:
sudo apt-get install libitpp-dev
g++ itpp-config --cflags example.cc itpp-config --libs
and everything works.

But in eclipse there are many errors like:
"/home/marco/workspace/example0/Debug/../src/example0.cpp:21: riferimento non definito a "itpp::linspace(double, double, int)""

Debug doesn't work!!

I tried also to use:
% mkdir build
% cd build
% cmake ..
% make
% make install
but also in this way i don't understand in which way I can link the library.

Please help me!!!

There are two different questions in your message:

• how to compile and run a program with Eclipse: I haven't used Eclipse recently, but you could use a project with Makefiles and then use itpp-config flags to compile a debug version. You need to use the debug flags. Then open the binary in eclipse and debug as usually

• how to install IT++ from Eclipse: use cmake generator for Eclipse CDT, so the third step should be:
  cmake .. -G "Eclipse CDT4 - Unix Makefiles"

The above described procedure can be used to compile and install IT++ from command line, once IT++ installed you could use Eclipse to compile your program using Makefiles for example

Sorry is several day that try to create a make file in eclipse.

Can give me more detail about how to create the progect?

I hace the main.cpp, bbb.h and comm.h (the file .h included in main).

Sorry for the stupid question

Here is a possible way of compiling your code with IT++ from Eclipse:
- create a 'Makefile Project with Existing Code'
- select the folder where the sources reside
- goto Project->Make Target->Create ...
- use as 'Target Name' the name of your file without the '.cpp' prefix
- in the left pannel switch the view to 'Make Target'. The previous target name should appear here
- double click the target name. Your file should compile if in the source folder there is a Makefile with the following content:

CXX           = g++

% : %.cpp
    $(CXX) `itpp-config --cflags` $< `itpp-config --libs` -o $@

%_d : %.cpp
    $(CXX) `itpp-config --debug --cflags` $< `itpp-config --debug --libs` -o $@

If you need to compile your file in debug mode use as target name 'fileName_d'

This is one possible approach, another one is to use cmake and to generate directly Eclipse project files.
