我注意到还有一些人有问题，我看到的唯一解决方案是CXXFLAGS和LDFLAGS，但这些似乎不起作用。
试图编译C++ PythBuffi以替代Python版本i，用VielalEnv和用户帐户在CENTOS上编译和安装：
$ 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
弹出一条消息说：
库已安装在：
/home/myuser/usr/lib
如果您想链接到已安装的库
在给定的目录libdir中，必须使用libtool，并且
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 theld_library_path'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'链接器标志-让系统管理员将libdir添加到`/etc/ld.so.conf'
好的，继续：
(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
结果是：

最佳答案
setuptools似乎没有注意到CXXFLAGS环境变量——您可以看到CXXFLAGS没有出现在gcc命令行中。看起来它甚至没有意识到它正在编译C++，考虑到它使用的是gcc而不是g++。尝试改用CFLAGS。
