Question

尝试在已编译Python 3.6.4的Linux系统上安装GEOS-3.6.2。我正在尝试使用以下命令创建包：

export PYTHON=/usr/local/bin/python3 && make && sudo make install

configure命令失败，显示：

...much snipped...
checking for swig... /usr/bin/swig
checking for SWIG version... 3.0.8
configure: SWIG executable is '/usr/bin/swig'
configure: SWIG library directory is '/usr/share/swig3.0'
checking for python version... 3.6
checking for python platform... linux
checking for python script directory... ${prefix}/lib/python3.6/site-packages
checking for python extension module directory... ${exec_prefix}/lib/python3.6/site-packages
checking for Python include path... /usr/local/include/python3.6m
checking for Python library path... 
configure: error: cannot find Python library path

我已经确认Python库存在于/ usr / local / lib / python3.6 / config-3.6m-x86_64-linux-gnu / libpython3.6m.a`

我用简单的./configure --prefix=/usr/local && make && sudo make install

编译了python

感谢Knud上面的评论能够让GEOS正确编译。 Python现在配置了./configure --prefix=/usr/local --enable-shared，后跟sudo ldconfig -v /usr/local/lib

遵循这些行动，GEOS与export PYTHON=/usr/local/bin/python3 && ./configure --prefix=/usr/local --enable-python && make && sudo make install

编译得很好

更新：在尝试在另一个系统上构建GEOS时，我又遇到了这个问题。这次解决方案略有不同。 Python编译构建库，文件名为libpython3.6m.so.1.0。 GEOS配置正在寻找libpython$PYTHON_VERSION.*的模式。如果确定python版本为3.6，这个系统正在返回，那么由于添加了'm'，构建将失败。

额外的FIX是在库目录中添加符号链接ln -s libpython3.6m.1.0 libpython3.6.so。

在Linux上使用Python模块编译GEOS 3.6.2
