我想在我的linux架构系统上构建一个Windows应用程序（.exe）。
#include <stdio.h>
#include <string.h>
#include <malloc.h>
#include <ctype.h>
#include <stdlib.h>
#include <regex.h>
int main()
{
//regcomp()...
//regexec()...
//regfree()...
}
$i686-w64-mingw32-gcc nc.c-o nc.exe（这不起作用）
nc.c:7:10: fatal error: regex.h: No such file or directory
#include <regex.h>
^~~~~~~~~
compilation terminated.
$gcc nc.c-o nc（这是工作）
无法用
.exe生成i686-w64-mingw32-gcc，这将显示关于#include <regex.h>的错误。但是可以用'gcc'编译linux。
如何解决
i686-w64-mingw32-gcc的问题？我还下载了
mingw-libgnurx-2.5.1-src.tar.gz$./configure--host=x86_64-w64-mingw32

最佳答案
您可以检查gnulib，看看它是否提供了与Windows兼容的<regex.h>。PCRE已经被移植到Windows上，并且它提供了一个<regex.h> replacement。PCRE还被打包用于Arch Linux的mingw-w64交叉编译，在mingw-w64-pcre2包中（因为您似乎正在使用archlinux）。
远离mingw-libgnurx-2.5.1-src.tar.gz。警告显示它与x86-64不兼容，因为64位Windows上的long仅为32位，正如警告所示，库作者显然没有预料到这一点。
