How to install GSL "properly" in Code::Blocks

[Ronny_C]

I am a newbie to C++ and codeblock. I hit a question when I installed GSL in CodeBlocks. I have already read this thread http://forums.codeblocks.org/index.php/topic,13375.0.html. I follow the idea suggested in the post  right click project -> build options -> Search Directories tab -> under complier, linker and resource complier, I add the following paths:

C:\Program Files\GnuWin32\src\gsl\1.8\gsl-1.8
C:\Program Files\GnuWin32\include\gsl
C:\Program Files\GnuWin32\contrib\gsl\1.8\gsl-1.8
C:\Program Files\GnuWin32\info
C:\Program Files\GnuWin32\doc\gsl\1.8\gsl-1.8

Then I run my testing code
#include <iostream>
 #include <stdio.h>
 #include <gsl_sf_bessel.h>  /
 #include <gsl_mode.h>
using namespace std;
     int
     main (void)
     {
       double x = 5.0;
       double y = gsl_sf_bessel_J0 (x);
       printf ("J0(%g) = %.18e\n", x, y);
       return 0;
     }

there was no error message for calling the header gsl_sl_bessel.h because this file poped out in code::block console; however, more error messages came  out  saying that the system couldn't find header files which were called by gsl_sl_bessel.h. Does anyone has a clue how to solve the problems. thanks

Why did you NOT add this one under the Compiler Search Directories?

Code

C:\Program Files\GnuWin32\include

How to install GSL "properly" in Code::Blocks

An more accurate title would be how to setup an Code::Blocks project to use the GSL Library.

Turn on Full Compiler Logging, in order for your to learn what Code::Blocks sends to the Compiler.

Thanks a lot, Stahta01. After following your advice and looking up the wiki.codeblocks.org, I found a solution to set the search paths grobally in the option called Complier and degugger. Then I set a full debugger mode in CodeBlocks, it seemed the problem finding header file disappeared; however, there was a problem when I called the function. I used the command call find declaration of "Function" by right click on the target function, let say gsl_sf_bessel_J0. The header file which the function was declared there came out and gave a proper location (exact line number) of the function. Then I used the command called find the implementation of "Function", no file came out on the computer screen but a message saying no such file existed. Does anyone have a clue how to solve it? Thanks!

You've done the wrong thing - library setting should not be set in the global compiler settings, they should be set in the project's build options instead.

p.s. read about global variables they are very useful...

[Ronny_C]

I have done what you have suggested. I got no sign to get rid fo my problem. Regarding to your Global variables. I wonder if you could give me more hits please.

[oBFusCATed]

Search the wiki about them... (global variables)

p.s. adding search paths to the compiler works, but your project is not transferable to other computers.
