How to specify the gcc version when using this package? #47

Closed bryanloz-xilinx closed 2 years ago

bryanloz-xilinx commented 2 years ago

Comment:

Say we want to restrict the gcc version to 7.3, how do we specify that when installing this package?

can we do something like: conda install cxx-compiler gcc=7.3 -c conda-forge

bryanloz-xilinx commented 2 years ago

Looks like conda-forge only provides back to 8.5

$ conda search -f gcc -c conda-forge

So this would work to use old gcc

conda install cxx-compiler gcc=8.5 -c conda-forge

It has been nice chatting with you @bryanloz-xilinx
