Question

我正在尝试在OS X 10.8（Mountain Lion）上构建text库，但我得到以下错误：

beta@lucy:/tmp/text-0.11.2.2 ☺ $ cabal configure

我正在使用GHC 7.4.2。安装了以下版本的gcc / llvm-gcc（通过XCode的命令行工具）：

gcc：

/usr/bin/gcc
beta@lucy:/tmp/text-0.11.2.2 ☺ $ gcc -v

指出问题可能是什么？其他人可以在Mountain Lion上构建text吗？

Answer 1

我在10.8.5上安装PAKCS时也遇到了这个问题。

我的解决方案是

安装Apple gcc-4.2
brew install apple-gcc42
编辑/ usr / bin / ghc并按如下方式更改pgmgcc
pgmgcc="/usr/local/bin/gcc-4.2"
参考What's the best workaround for not having "cabal upgrade"?

最后，我可以完成我的text软件包安装。

我希望你玩得开心！

另见： Cabal doesn't work on Mac OS X Lion because of gcc path
