MinGW编译wxWidgets问题

来源:互联网 发布:c语言实验体会 编辑:程序博客网 时间:2024/05/16 16:55

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 (下面贴出的congfig.gcc文件中的红色标记部分为需要修改的地方)
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:
