我尝试根据本手册在 Ubuntu 12.04 上编译 HHVM 。
我收到此错误：
$ cmake .
Using HPHP_HOME == /home/foo/dev/hhvm
-- CMAKE_PREFIX_PATH was missing, proceeding anyway
CMake Error at CMake/HPHPCompiler.cmake:11 (message):
Need at least GCC 4.7
但 GCC 4.7 似乎安装正确
$ gcc -v 使用内置规范。 COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/4.7/lto-wrapper 目标：x86_64-linux-gnu 配置：../src/configure -v --with-pkgversion='Ubuntu/Linaro 4.7.3-2ubuntu1~12.04' --with-bugurl=file:///usr/share/doc/gcc-4.7/ README.Bugs --enable-languages=c,c++,go,fortran,objc,obj-c++ --prefix=/usr --program-suffix=-4.7 --enable-shared --enable-linker-build-id --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.7 --libdir=/usr/lib -- enable-nls --with-sysroot=/ --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-gnu-unique-object --enable-plugin --with -system-zlib --enable-objc-gc --enable-multiarch --disable-werror --with-arch-32=i686 --with-abi=m64 --with-multilib-list=m32,m64 -- with-tune=generic --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu 线程模型：posix gcc 版本 4.7.3 (Ubuntu/Linaro 4.7.3-2ubuntu1~12.04)
