Hi,
when trying to install Reppy on OSX Mojave 10.14.x, I ran into a problem that many others seem to have with similar libraries:
The gcc compiler from the OSX developer tools does not find standard header files, like so
warning: include path for stdlibc++ headers not found; pass '-stdlib=libc++' on the command line to use the libc++ standard library instead [-Wstdlibcxx-not-found]
reppy/rep-cpp/src/agent.cpp:1:10: fatal error: 'algorithm' file not found
#include <algorithm>
^~~~~~~~~~~
1 warning and 1 error generated.
error: command 'gcc' failed with exit status 1
The solution is pretty simple, yet hard to find: You need to set the environment variable MACOSX_DEPLOYMENT_TARGET to 10.14 for Mojave and likely 10.15 for Catalina, like so
export MACOSX_DEPLOYMENT_TARGET=10.14
Then,
pip install reppy
or, what I used
pip install --user --force-reinstall --ignore-installed --no-binary :all: reppy
work like a charm.
I spent hours trying to fix this, so maybe this is useful for others :-).
A route that did not work out well was using Homebrew to install a standard GCC compiler, btw.
Thanks to @ChristophSchmidl who gave this hint at:
