我正在使用以下命令行为Windows编译WxWidgets:
mingw32-make -f makefile.gcc BUILD=release SHARED=1 -j6
最后一个参数(-j
)用于通过运行multiple jobs in parallel加速编译,在我的情况下充分利用我的6核处理器。单线程构建通常需要非常长。
但是,按Enter键我得到以下输出:
if not exist gcc_mswudll mkdir gcc_mswudll
if not exist ..\..\lib\gcc_dll mkdir ..\..\lib\gcc_dll
if not exist ..\..\lib\gcc_dll\mswu\wx\setup.h copy ..\..\include\wx\msw\setup.h ..\..\lib\gcc_dll\mswu\wx\setup.h

然后,如果我再次重复相同的命令,则会显示以下输出:
if not exist ..\..\lib\gcc_dll\mswu mkdir ..\..\lib\gcc_dll\mswu
if not exist ..\..\lib\gcc_dll\mswu\wx\setup.h copy ..\..\include\wx\msw\setup.h ..\..\lib\gcc_dll\mswu\wx\setup.h

然后......如果我第三次尝试,编译就会成功完成。
问题:是否可以按照此过程并行构建WxWidgets,或者有可能在以后使用已编译的二进制文件时导致问题?
答案 0 :(得分:2)
不幸的是,MSW makefile中确实存在一个错误,缺少setup_h
目标上各种库的依赖关系。首先make setup_h
然后make -jN
。
或者,您可以使用配置进行构建,如此旧但仍然有效的post中所述,然后只需make -jN
完全正常。
