MinGW编译wxWidgets问题

其实利用MinGW编译wxWidgets是一件挺简单的事情，但是最近在编译的时候遇到一些问题，并找到解决方案，因此在此分享一下个人经验。编译出错的原因是由于安装了MSYS的缘故。

错误信息类似于如下的结果：

if not exist ../../lib/gcc_lib/mswud/wx mkdir ../../lib/gcc_lib/mswud/wx

process_begin: CreateProcess(NULL, -c "if not exist ../../lib/gcc_lib/mswud/wx mkdir ../../lib/gcc_lib/mswud/wx", ...) failed.

make (e=2)

产生错误的原因是因为安装了MSYS后，利用Make命令会首先执行MSYS中的SHELL命令，从而会导致编译错误，对于这种情况，可以修改 $(WX)/build/msw目录中的makefile.gcc文件，使其默认采用CMD命令行。

makefile.gcc修改前：  SHELL := $(COMSPEC)

makefile.gcc修改后：  C:\WINDOWS\system32\CMD.exe     (该路径为实际的CMD.exe的路径)

==============================================================================

最后还是顺便说一下MinGW编译wxWidgets的流程：

1 下载源代码 http://www.wxwidgets.org/downloads/

2 修改 $(WX)/build/msw 目录中的makefile.gcc文件  (可选)

3 修改 $(WX)/build/msw 目录中的congfig.gcc文件 ()

4 在控制台进入到 $(WX)/build/msw 目录中，执行 mingw32-make -f makefile.gcc

注： $(WX)表示你下载的源代码解压后的路径

对编译过程还不明白的可以查看官方说明：
