Re: [Help-gsl] Cannot access GSL functions

[CRUZ-CAVALCANTI, Yanna]

Hello, Brian,

I am really thankful for your answer. It is true that I am building GSL with 
Visual Studio 2010. But actually my program worked one year ago when someone 
else was using it. Also, fortran does not uses it. My fortran code calls my c++ 
code, which is linked to gsl. I see it enters my c++ code and it stops in the 
first gsl function. That is why I do not think there is a problem with fortran. 
I do not understand either why he compiles well, he finds the libraries, but he 
crashes after being turned into .exe.

I tried what you suggested and the tests for gsl library succeeded very well. 

Just to be more specific, below I show you the steps I am following to install 
the library GSL 1.8 and link it to my Visual Studio 2010. Is any step missing? 
Do you think it would be better to use a more recent version of gsl? If yes, 
where I can find it and what manual to link it to Visual Studio 2010 can I use?

I am very glad with your answer and I am sorry to occupy your time with this, 
but there are more than 3 weeks that I am trying to solve this problem and it 
is really retarding me. I have no one to help me with this where I am.

I thank you again in advance.

Yanna


Steps:

1.      INSTALL VISUAL C++ 2010 EXPRESS 
Open your Administrator account. Copy "vc_web.exe" on your desktop then install 
it.
2.      BUILD GSL LIBRARIES FOR Visual studio
- Copy "gsl-1.8-src" folder in  C:\downloads                                    
                                        - Launch Visual C++ 2010 Express
- Open project C:\downloads\gsl-1.8-src\src\gsl\1.8\gsl-1.8\VC8\libgsl.sln
- Continue with convert, and do build solution (press F7)    
- Verify that after build is complete, new dll files are generated in 
subfolders in 
. C:\downloads\gsl-1.8-src\src\gsl\1.8\gsl-1.8\VC8\libgsl\Debug-DLL
. and
. C:\downloads\gsl-1.8-src\src\gsl\1.8\gsl-1.8\VC8\libgslcblas\Debug-DLL
3.      INCLUDE THE GSL LIBRARY
- Launch Visual studio
- Open project Simulator's folder\Gene_IQ\Source_Files\geneIQ_multi_v1.sln
- Select menu Project -> properties
- On the tree display in your project properties dialog box, select branch for 
Configu-ration Properties->VC++ directories
- On the right side of the dialog, click on the field for "Executable 
Directories". Click on . dropdown button. Choose edit, a dialog for "Executable 
directories" will be launched. . Click on button for new line. Put these into 
the field (one at a time):
. C:\downloads\gsl-1.8-src\src\gsl\1.8\gsl-1.8\VC8\libgsl\Debug-DLL
. C:\downloads\gsl-1.8-src\src\gsl\1.8\gsl-1.8\VC8\libgslcblas\Debug-DLL
- On the right side of the dialog, click on the field for "Include 
Directories". Click on      . dropdown button. Choose edit, a dialog for 
"Include directories" will be launched.      . Click on button for new line. 
Put this into the field:
. C:\downloads\gsl-1.8-src\src\gsl\1.8\gsl-1.8
- On the right side of the dialog, click on the field for "Library 
Directories". Click on       . dropdown button. Choose edit, a dialog for 
"Library directories" will be launched.       . Click on button for new line. 
Put these entries into the field (one at a time):
. C:\downloads\gsl-1.8-src\src\gsl\1.8\gsl-1.8\VC8\libgsl\Debug-DLL
. C:\downloads\gsl-1.8-src\src\gsl\1.8\gsl-1.8\VC8\libgslcblas\Debug-DLL
- In the property pages dialog, select tree item "configuration 
properties->Linker-> In    . put
- On the right hand side details, choose the field "Additional Dependencies". 
Click on   . dropdown button. Choose edit and replace what you will find by 
these two lines:
. libgsl_dll_d.lib
. libgslcblas_dll_d.lib
- In the property pages dialog, select tree item "configuration 
properties->C++-> Pre   . processor

-  Click on edit field for preprocessor definitions. Click on dropdown button. 
Choose    . edit. In the "Preprocessor definitions" dialog, add the following 
entry :
. GSL_DLL                                                                       
                                                 -  Press ok to save all your 
changes.                                                                   -  
Do build solution (press F7).
A new "geneIQ_multi.exe" must have been generated. It will be automatically 
saved in Si-mulator's folder\Gene_IQ

Hi,

>From what you say, you appear to be using a Visual Studio build for GSL.
 When you built GSL, did you also build and run all the GSL tests?

If these tests pass, it is possible that the problem lies in the way the
GSL library is linked into your fortran90 code.

Have you checked that the compiler that built the Fortran program and
that used to provide GSL operate with compatible library and binary
formats?

The Intel C++ and Fortran compilers on Windows are compatible and can be
used for mixed language development.

But I am not sure about mixing a library produced with the Microsoft
compiler with code produced by non Microsoft compilers.  I have heard
that this works but I also know of situations where this has produced
failures.
