Intel CC on Linux

gistfile1.txt

Earlier "icc" emulated "gcc"; nowadays it is a "clang"

* wget from intel site https://software.intel.com/content/www/us/en/develop/tools/oneapi/base-toolkit/download.html?operatingsystem=linux
* run the shell installer (may need to `export TERM=vt100` in console mode)
* use wrapper script below as /usr/bin/icc (symlinks as i++ and icc-cpp, maybe suffixed with version from path component e.g. icc-2021.3.0)
----
# copy-paste the file as /usr/bin/icc
chmod +x /usr/bin/icc
( cd /usr/bin && for I in i++ icc-cpp icc-cpp-2021.3.0 icc-2021.3.0 i++-2021.3.0 ; do ln -s icc $I ; done )
----
* if you build with suffixes of well-known compilers, this may do better:
----
( cd /usr/bin && for I in clang-cpp-icc-2021.3.0 clang++-icc-2021.3.0 clang-icc-2021.3.0 ; do ln -s icc $I ; done )
----
* optionally symlink the names into /usr/lib/ccache (as links to ../../bin/ccache):
````
( cd /usr/lib/ccache && for I in icc i++ icc-cpp icc-cpp-2021.3.0 icc-2021.3.0 i++-2021.3.0 ; do ln -s ../../bin/ccache $I ; done)
