Question

我在使用brew安装valgrind时遇到了一些麻烦。我正在使用命令：

brew install valgrind

并收到错误

==> ./configure --prefix=/usr/local/Cellar/valgrind/3.9.0 --enable-only64bit -- build=amd64-darwin
checking for gcc... gcc-4.2
checking whether the C compiler works... no

我在gdb中遇到类似的错误

有谁知道会出现什么问题？我是OS X 10.9.4。

Answer 1

checking for gcc... gcc-4.2
gcc version 4.9.0 (Homebrew gcc49 4.9.0)

brew和手动运行的输出显示了2个单独版本的gcc，而brew正在拿起真正的旧版本。设置您的环境，以便which gcc返回4.9版本。

Answer 2

答案就在这里

Using Homebrew with GCC-4.6

我通过安装

解决了这个问题

HOMEBREW_CC=gcc-4.9 HOMEBREW_CXX=g++-4.9 brew install gdb

和

HOMEBREW_CC=gcc-4.9 HOMEBREW_CXX=g++-4.9 brew install valgrind

Answer 3

您应该可以使用brew来执行此命令在Yosemite上安装valgrind：brew install --HEAD valgrind，最糟糕的是您可能需要先执行以下设置命令：HOMEBREW_CC = gcc-4.5 HOMEBREW_CXX = g ++ - 4.5 brew

用brew安装valgrind和/或gdb？
