Currently rhel has GMP version 4.something
PyCrypto needs GMP >= 5
Because rhel is slightly behind we have to re-make The GNU Multiple PrecisionArithmetic Library stuff.
For this we have to download the sources from https://gmplib.org/#DOWNLOAD
According to the instructions from the package:
tar -xvjpf gmp-6.0.0a.tar.bz2
./configure
make
make check <= VERY IMPORTANT!!
make install
With the right libraries we rebuild PyCrypto
pip install --ignore-installed PyCrypto
As a side note, whenever building and re-building do a
yum -y groupinstall "Development tools"
yum -y install gcc libgcc glibc libffi-devel libxml2-devel libxslt-developenssl-devel zlib-devel bzip2-devel ncurses-devel
It will take care of many problems you might encounter due to missing compilersand header files.
