c++ - 使用 GAlib 模板实例化的 Cygwin gcc 编译器问题

Question

所有，我在 Win 7 pro x64 上使用 Cygwin gcc 4.8.1 和 Netbeans 7.3.1。我尝试构建 GAlib 项目但遇到模板实例化问题:

我还在 gaconfig.h 中定义了 NO_AUTO_INST，但错误仍然存​​在。那么如何解决这个问题呢？

你想要

g++ -g -Wall -I.. -c ex17.C

成为

g++ -g -fpermissive -Wall -I.. -c ex17.C

我编译了 galib ( http://lancet.mit.edu/ga/dist/galib247.tgz )，它也在 ex17.C 编译时停止，同样使用 g++ 4.8.1 版。 Cygwin 就像 linux 的工具一样，所以在顶层源目录中是文件 makevars(不是 makevars.bcc 也不是 makevars.vcpp)。在 makevars 中，更改下面已经取消注释的行

# gcc3, gcc4
#
#
CXXFLAGS    = -g -Wall

到

CXXFLAGS    = -g -fpermissive -Wall

您可能没有在 cygwin 中运行 X，但我也将它放在 examples/graphic/makefile 中并将 wigdet 设置也更改为 athena，并为小部件 header 安装了 libxaw7-dev 包
