Question

我正在尝试在必须在非标准位置安装libsnappy-dev的系统上安装this package，并且不知道如何在自动安装中包含正确的标志以帮助gcc找到开发文件。

可以预见，当我尝试使用

从github安装时

pip git+git://github.com/andrix/python-snappy

我收到编译错误，因为无法找到.h文件（在非标准位置）。

我只是一个构建软件的黑客，但我想我需要像这样设置LDFLAGS变量：

export LDFLAGS="-L/app/vendor/snappy/usr/local/lib -L/app/vendor/snappy/usr/local/include"

但是，这并没有使其成为上面列出的gcc调用。有关如何解决此问题的任何想法？

编辑：进度。分叉活泼和改变

snappymodule = Extension('_snappy',
                     libraries=['snappy'],
                     sources=['snappymodule.cc', 'crc32c.c'])

到

snappymodule = Extension('_snappy',
                     libraries=['snappy'],
                     sources=['snappymodule.cc', 'crc32c.c'],
                     extra_compile_args=['-L/app/vendor/snappy/usr/local/lib -L/app/vendor/snappy/usr/local/include', 
                     '-I/app/vendor/snappy/usr/local/lib -I/app/vendor/snappy/usr/local/include'])

已将错误发展到

gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/app/.heroku/python/include/python2.7 -c snappymodule.cc -o build/temp.linux-x86_64-2.7/snappymodule.o -L/app/vendor/snappy/usr/local/lib -L/app/vendor/snappy/usr/local/include -I/app/vendor/snappy/usr/local/lib -I/app/vendor/snappy/usr/local/include

意味着我们至少可以通过标志。仍然试图弄清楚正确的标志是什么。手动检查仍然确认snappy.h在附近。

~/vendor/snappy/usr/local/include $ pwd
  /app/vendor/snappy/usr/local/include
~/vendor/snappy/usr/local/include $ ls
  snappy-c.h  snappy.h  snappy-sinksource.h  snappy-stubs-public.h

将编译器标志传递给python包安装
