Error while installing on Mac

[vsumaria]

I followed the steps mentioned in the README.Macos for installing P4vasp on Macbook Pro (MacOS Mohave, v.10.14..3), but am having some issue.

I get the following error:

g++-7 -fpic -g -DPY_DOMEXC_MODULE=""xml.dom."" -Ipython -c "import sys;import os.path;print os.path.join(sys.prefix,\"include\",\"python\"+sys.version[:3])" -Iinclude -c string.cpp -o string.o
/bin/sh: g++-7: command not found
make[1]: *** [string.o] Error 127
make: *** [p4vasp] Error 2

I am unable to find a way to fix this error.

Sorry for the delayed response.

Since the homebrew developers updated the gcc version to 8, you need to brew install gcc@7 for this to work.

Please see #12 for an updated MacOS compilation process.

brew install gcc@7 doesn't work on newer MacOS versions. I get following warning.

Warning: gcc@7 has been deprecated because it is deprecated upstream!
gcc@7: This formula either does not compile or function as expected on macOS
versions newer than Monterey due to an upstream incompatibility.
gcc@7: The x86_64 architecture is required for this software.
Error: gcc@7: Unsatisfied requirements failed this build.

@jlabs06 I am running into the same issue when trying to install GCC 7
