Title: Compile errors from mingw32's math.h of Code::Blocks v10.05 rev 6283
Post by: ophiuchus18 on July 20, 2011, 01:17:40 PM
When I compile C code,the Code::Blocks v10.05 rev 6283 default compiler (GNU GCC compiler) return these errors:

c:\program files\codeblocks\mingw\bin\..\lib\gcc\mingw32\4.4.1\..\..\..\..\include\math.h|563|error: expected ')' before '/' token|
c:\program files\codeblocks\mingw\bin\..\lib\gcc\mingw32\4.4.1\..\..\..\..\include\math.h|564|error: expected ')' before '/' token|
||=== Build finished: 2 errors, 0 warnings ===|


C:\Program Files\CodeBlocks\MinGW\include\math.h

The mingw32's math.h is damaged or what ? How to replace the math.h with a workable one ?

Don't put your compiler into the directories with spaces.

This is where Code::Blocks put the compiler by default:

C:\Program Files\CodeBlocks\MinGW

I would re-install, something got messed up if the default headers don't compile.

You most likely have a wrong config file "config.h" for the library/compiler configuration fix it.

You can confirm by defining "HAVE_LOG2F" to see if the error changes.

This is NOT a Code::Blocks problem or even likely a Compiler problem.

From math.h starting with line 562
Code Select

/* 7.12.6.10 */
extern double __cdecl log2 (double);
extern float __cdecl log2f (float);
extern long double __cdecl log2l (long double);

I think you have right with the config.h, it's an autogenerated file.

I downloaded cross-mingw.gcc453, MSYS.exe, Git-1.7.6.exe and yasm.exe and it's ok now. I made the .exe thing.

Thank you.
