Mac OS: Catalina: unable to execute 'gcc': No such file or directory

MAC OS Catalina(10.15.1) seems to have created some problems for building code that uses gcc. I am trying to build a python application which is running into the following error.

You need to download MPFR source code and compile it. See installation manual: https://gmpy2.readthedocs.io/en/latest/intro.html#installation

Mujoco-py has many dependencies. If you can't use the docker image, you have to install the dependencies yourself. Use sudo apt-get install to install the required libraries.
The current dockerfile lists these dependencies.
sudo apt-get install \
curl \
git \
libgl1-mesa-dev \
libgl1-mesa-glx \
libglew-dev \
libosmesa6-dev \
python3-pip \
python3-numpy \
python3-scipy \
net-tools \
unzip \
vim \
wget \
xpra \
xserver-xorg-dev
You might not need all of these, but it's probably no harm in installing everything. The error message in your question shows that GL/osmesa.h at least is required. That is probably included with one of the mesa packages in the list above.

For CentSO, I fix the problem by running the following commands:
sudo yum install mesa-libOSMesa-devel.x86_64
sudo yum install mesa-libGL-devel.x86_64
sudo yum install mesa-libGLU-devel.x86_64

How to change python gcc binding to gcc 4.8 version?

I want to install a auto-sklearn package which dependent on pyrfr.
The install command is curl https://raw.githubusercontent.com/automl/auto-sklearn/master/requirements.txt | xargs -n 1 -L 1 pip install.
My Env: ubuntu 12.04, python3.5-dev(in virtualenv) with gcc 4.8 and g++ 4.8 installed.
I install gcc and g++ by:
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
Defaut gcc is set correctly:

The key problem I think is python3.5 not link to gcc-4.8(even system default python2.7 not too), but google not help much.

Finnally I find the solution.. find that x86_64-linux-gnu-gcc is a command , though it doesn't looks like a command...
It seems python on ubuntu 12 would not use /usr/bin/x86_64-linux-gnu-gcc(link to /usr/bin/gcc-4.6) instead of /usr/bin/gcc, I totally coundn't understand why them do this ...
The sulotion is simple, just
cd /usr/bin
rm x86_64-linux-gnu-gcc
ln -sf gcc-4.8 x86_64-linux-gnu-gcc
If you want change g++ and cpp, also do
rm x86_64-linux-gnu-cpp
ln -sf cpp-4.8 x86_64-linux-gnu-cpp
rm x86_64-linux-gnu-g++
ln -sf g++-4.8 x86_64-linux-gnu-g++
