Question

Basic compile questions.

Asked by: hnaparst

This is the first time I've used Visual Studio.Net 2003.
I'm trying to compile the public source code for the SETI project.
I downloaded the SETI and boinc modules, opened the solution file for
SETI, and clicked on build.  223 errors resulted.  After making sure that _WIN32 was set (it wasn't originally),
The first error occurred trying to compile the line:

#ifdef _WIN32
    extern HINSTANCE g_hIdleDetectionDll;       // handle to DLL for user idle
#endif

The error message is:  c:\Documents and Settings\Harold\My Documents\boinc\lib\hostinfo.h(76) : error C2146: syntax error : missing ';' before identifier 'g_hIdleDetectionDll'

However, HINSTANCE, from what I can tell, is a standard type.  What do you think could be wrong here?  After I solve this, only 222 more error to go!

Maybe you need
#include "windows.h"
at the beginning of your source file, to HINSTANCE to be recognized.

 

by: hnaparstPosted on 2005-10-08 at 12:42:18ID: 15045674

You're not going to believe this.  I skeptically added the one line

#include <windows.h>

immediately above the offending code, and every one of the 233 compile errors went away.
A one line fix, and you found it.

Now the only problem is there is one unresolved external symbol.  Want to take a chance on this one?

seti_boinc error LNK2019: unresolved external symbol "unsigned int * __cdecl read_rgb_texture(char const *,int *,int *,int *)" (?read_rgb_texture@@YAPAIPBDPAH11@Z) referenced in function "public: int __thiscall TEXTURE_DESC::CreateTextureRGB(char const *)" (?CreateTextureRGB@TEXTURE_DESC@@QAEHPBD@Z)
 
Any idea about that one?

Forget it. I found the source code for the missing function.
Amazing that public source code could have basic mistakes like this.
I just needed to add an additional source file to the project and it linked.
Thanks a lot.
