我正在使用Debian Squeeze,使用mingw32为Windows目标交叉编译。使用mingw32未定义对posix_memalign的引用
对于Linux目标,我可以使用posix_memalign来分配对齐的内存。
我似乎无法找到一种方法来获得这个工作的Windows目标;我收到有关未定义引用的错误。我尝试了几种替代功能,但无济于事。
示例代码:
#include <stdio.h>
#include <stdlib.h>
#include <malloc.h>
int main(void)
{
char *foo;
/* works on linux */
posix_memalign(&foo, 1024, 1024);
/* deprecated linux */
memalign(1024, 1024);
valloc(1024);
/* should work on windows only */
_aligned_malloc(1024, 1024);
}
示例输出Linux目标(预计):
[email protected]:~/folder$ gcc --version
gcc (Debian 4.4.5-8) 4.4.5
[email protected]:~/folder$ gcc -std=c99 test.c
test.c: In function ‘main’:

示例输出Windows目标 - 注意,所有四个功能是不确定的

有没有想法?
__mingw_aligned_malloc工作!谢谢! – HoboBen
