Hi, All!
First of all I want to thank developers for your great work! CeGcc is very
useful and helpful. It gave me a reason to learn more about great
open-source tools.
Now as for my problem.
I'm trying to port small part of FFMPEG lib to WinCE and have some troubles
with linking with Microsoft Visual Studio 2005 Project
For porting I've created static lib project in VS2005, added files I was
needed and used custom build specification for them:
"D:\mingw32ce\bin\arm-wince-mingw32ce-gcc.exe" @command_debug -c
"$(InputPath)" -o "$(IntDir)\$(InputName).obj"
My command_debug file:
-std=c99
-D HAVE_AV_CONFIG_H
-D CONFIG_MPEG4_DECODER
-D ARCH_ARMV4L
-D ARM
-D NDEBUG
-D FFMPEG_EXPORTS
-D UNICODE
-D _WIN32
-D _WIN32_WCE
-D __MINGW32__
-D __cdecl=
-w
-mno-apcs-frame
-mtune=xscale
-march=armv4
-fno-leading-underscore
-fsigned-char
-I.
-Ilibavutil
-Ilibavcodec
-I/usr/include
-I/usr/include/w32api
I get lib file without any errors, but when I link it to another pure VS2005
project I get these unresolved external errors.
These symbols: _impure_ptr and __imp__ctype_ are not found in ffmpeg code,
so I think they come from one of CeGcc libraries.
This function has code that results in _impure_ptr unressolved external:
void av_log_default_callback(void* ptr, int level, const char* fmt, va_list
vl)
{
static int print_prefix=1;
AVClass* avc= ptr ? *(AVClass**)ptr : NULL;
if(level>av_log_level)
return;
#undef fprintf
if(print_prefix && avc) {
fprintf(stderr, "[%s @ %p]", avc->item_name(ptr), avc);
}
#define fprintf please_use_av_log
print_prefix= strstr(fmt, "\n") != NULL;
vfprintf(stderr, fmt, vl);
}
And __imp__ctype_ occurs if there was a call to _isctype() std function.
Can somedody help me, please?
