如何使用 mingw gcc 链接 msvcr90.dll?
如何使用 mingw gcc 链接 msvcr90.dll?我尝试了 -lmsvcr90,这是最小的示例:
#include <stdio.h>
int main(int argc, const char *argv[]) {
printf("%s\n", "hello");
return 0;
}
我的操作系统是 win7,使用 mingw gcc 4.5.0
$ gcc -v
...
gcc version 4.5.0 (GCC)
$ gcc hello.c -lmsvcr90
$ a
然后我收到此错误:
R6034
An application has made an attempt to load the C runtime library incorrectly. Please contact the application's support team for more information.
我缺少哪一部分?
edit1:
@user440813 看来我的mingw和你的很不一样。
$ gcc h.c -nostdlib -lmsvcr70 -lgcc -o h.exe
d:/mingw/bin/../lib/gcc/mingw32/4.5.0/libgcc.a(__main.o):(.text+0x5a): undefined reference to `atexit'
d:/mingw/bin/../lib/gcc/mingw32/4.5.0/libgcc.a(__main.o):(.text+0xc2): undefined reference to `atexit'
collect2: ld returned 1 exit status
然后我嘲笑了 int atexit ( void ( * function ) (void) ) {return 0;}
并再次得到了 R6034 ...

Which part am I missing ?
edit1:
@user440813 Seems my mingw is very different from yours.
$ gcc h.c -nostdlib -lmsvcr70 -lgcc -o h.exe
d:/mingw/bin/../lib/gcc/mingw32/4.5.0/libgcc.a(__main.o):(.text+0x5a): undefined reference to `atexit'
d:/mingw/bin/../lib/gcc/mingw32/4.5.0/libgcc.a(__main.o):(.text+0xc2): undefined reference to `atexit'
collect2: ld returned 1 exit status
Then I mocked int atexit ( void ( * function ) (void) ) {return 0;}
and got R6034 again ...

尝试
一下。我对您最初的编译尝试成功感到有点惊讶,因为
msvcr90
和msvcrt
(MinGW 默认链接的)之间应该存在冲突的定义。这样,msvr90
就会被链接,冲突的msvcrt
则不会,但会添加libgcc
以初始化运行时库。我的计算机上没有
msvcr90.dll
,但我能够验证类似的调用是否适用于msvcr100.dll
。Try
instead. I'm a little surprised that your original compilation attempt succeeded, since there should've been conflicting definitions between
msvcr90
andmsvcrt
(which MinGW links in by default). This way,msvr90
gets linked in, the conflictingmsvcrt
doesn't, butlibgcc
gets added in order to initialize the runtime library.I don't have
msvcr90.dll
on my computer, but I was able to verify that the analogous invocation works withmsvcr100.dll
.
