CVS build broken for GCC/Make

Ryz · Post by **Ryz** » Fri Feb 17, 2006 11:14 am

The current make dies on the compiling of makesdna.c, as it refers to guardedalloc/mallocn.a, which now seems to have an unreferenced function _nunmap

After being pointed out on IRC that there was a thread on a new memory management change as reported on bf-commit, I thought someone with CVS access might want to know...

same problem with scons and msvc 7.1 :

Linking library ==> 'blender_img.lib'
Compiling ==> 'makesdna.c'
makesdna.c
Linking program ==> 'makesdna.exe'
bf_guardedalloc.lib(mallocn.obj) : error LNK2019: unresolved external symbol _mu
nmap referenced in function _rem_memblock
E:\bf-blender\build\win32-vc\makesdna.exe : fatal error LNK1120: 1 unresolved ex
ternals
scons: *** [E:\bf-blender\build\win32-vc\makesdna.exe] Error 1120
scons: building terminated because of errors.

Problem is in mallocn.c, on lin 44 You can find:

Code: Select all

#if defined(AMIGA) || defined(__BeOS) || defined(WIN32)
#else
#include <sys/types.h>
#include <sys/mman.h>
#endif

No mman.h for Windows (win32 platform misses mmap and munmap) so munmap symbol missing (_munmap in libguardedalloc.a).

Quick fix for now, until a proper solution has been implemented:

Thanks all. I had tried to use the mmap/munmap/sbrc etc. equivalent code listed for Windows, but couldn't get it to work with the CRITICAL_SECTION part that was listed... Someone with more than rudimentary C/C++ knowledge (like I have) should have a look at that...

Erwin committed a temporal fix to this file, so perhaps you can compile now.

Yeah, I read that follow-up

Make is running now...

[Edit: and finished fine]

Just posted in the patch tracker:

here's an implementation of mmap & munmap for the win32 platform.

By including it in mallocn.c at line 44 I succeded in compiling blender.

Hope it can be of any help

Nice! Hope it shows up soon in the CVS too...
