问题描述
我正在尝试安装python库pyinterval.它需要我没有错误安装的crlibm C头文件，但这似乎是问题的根源.
I am trying to install the python library pyinterval. It requires the crlibm C headers which I have installed without error, but seem to be at the root of the problem.
当我跑步时:
$ sudo easy_install pyinterval
我得到以下信息:

/usr/local/lib/libcrlibm.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
error: Setup script exited with error: command 'gcc' failed with exit status 1
我给:
$ sudo apt-get install python-all-dev
并不能解决问题.
推荐答案
如果仍然有人对此有疑问，则需要在"scs_lib/Makefile"(而不是"./Makefile")中设置"CPPFLAGS = -fPIC".
In case anyone still has problems with this, you need to set "CPPFLAGS = -fPIC" in "scs_lib/Makefile", not "./Makefile".
