all, I am using Cygwin gcc 4.8.1 with Netbeans 7.3.1 on Win 7 pro x64. I tried to build the GAlib project but encounter the template instantiation issues:

I also defined NO_AUTO_INST in the gaconfig.h, but the errors persists. So how to fix this problem?

你要

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 )，它也停止在 ex17.C 编译，也使用 g++ 4.8.1 版本。Cygwin 对于工具来说就像 linux，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，更改以下已取消注释的行

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

至

CXXFLAGS    = -g -fpermissive -Wall

您可能没有在 cygwin 中运行 X，但我也将它放在了示例/图形/makefile 中，并将 wigdet 设置也更改为 athena，并为小部件标头安装了 libxaw7-dev 包
