Compile errors from mingw32's math.h of Code::Blocks v10.05 rev 6283
« 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 ?

If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

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

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

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

From osdep.h http://git.videolan.org/?p=x264.git;a=blob;f=common/osdep.h;h=6249dbe0c53085167a4556ce85c4a8136abbfc90;hb=HEAD#l43
Code
  43 #if !HAVE_LOG2F
  44 #define log2f(x) (logf(x)/0.693147180559945f)
  45 #define log2(x) (log(x)/0.693147180559945)
  46 #endif

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.
