C Compiler Issue

[jstader]

1. There are many types of RINEX files.
   Almost every issue is because of some corner case with a particular RINEX format.
   Thus we will usually need a copy of your RINEX file.
   If it's very large/private, consider copying just the part of it that causes the issue for you.
2. Please copy and paste the error traceback, to help find which function the error is occurring in.
3. generally a dump of all the versions of Python packages you have is not needed

RuntimeError: could not build Hatanka converter. Do you have a C compiler?

I have the home-brew gcc installed but python is complaining I don't have a compiler?

It could be that you do not have "write" permission for the directory /usr/local/lib/python3.7/site-packages/georinex/rnxcmp/

from Terminal, are you able to do:

touch /usr/local/lib/python3.7/site-packages/georinex/rnxcmp/foo

and have that file "foo" created?
