Question

我注意到其他一些人遇到了问题，我看到的解决方案只包括CXXFLAGS和LDFLAGS，但那些似乎不起作用。

尝试使用virtualenv和用户帐户编译和安装在CentOS上的替代Python版本的C ++ protobuff：

$ cd ~/myApp
$ /opt/python-2.7/bin/virtualenv python
$ source ~/myApp/python/bin/activate
(python)$ cd ~/src/protobuf-2.5.0
(python)$ ./configure --prefix=$HOME/usr
(python)$ make && make install

向上弹出一条消息说：

已安装的库：      /家庭/为myuser / usr / lib中

如果您碰巧想要链接已安装的库   在给定目录LIBDIR中，您必须使用libtool和   指定库的完整路径名，或使用-LLIBDIR' flag during linking and do at least one of the following: - add LIBDIR to the LD_LIBRARY_PATH＆＃39;环境变量        执行期间       - 将LIBDIR添加到LD_RUN_PATH' environment variable during linking - use the - Wl，-rpath -Wl，LIBDIR＆＃39;链接器标志       - 让系统管理员将LIBDIR添加到`/etc/ld.so.conf'

好的，继续前进：

(python)$ export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp
(python)$ export CXXFLAGS=-I$HOME/usr/include
(python)$ export LDFLAGS=-L$HOME/usr/lib
(python)$ cd python
(python)$ python setup.py build

然后它退出：

似乎setuptools没有关注CXXFLAGS环境变量 - 您可以看到CXXFLAGS命令行中没有显示gcc。考虑到它使用gcc而不是g++，它似乎甚至不知道它正在编译C ++。请尝试使用CFLAGS。
