my problem is that I want to invoke the icc compiler from the commandline, but my pc can't find it. I have install the latest oneAPI and sourced setvars.sh.
Even I search 'icc' file under the installation routine I can't find the icc compiler file.
'which' command works for mpicc and dpcpp but not for icc can not find icc/// mpicc found but not icc
It looks like you might have installed Intel OneAPI base toolkit. The icc compiler is not a part of the base toolkit. To get icc(Intel® C++ Compiler Classic) you should install Intel OneAPI HPC toolkit. Below is a link to HPC toolkit. You would see icc in the "whats included" section
https://software.intel.com/content/www/us/en/develop/tools/oneapi/hpc-toolkit.html
You could install hpc toolkit on the top of your basekit, it installs only whatever is not present as a part of base toolkit.
icc is the "classic" compiler:
apt install intel-oneapi-compiler-dpcpp-cpp-and-cpp-classic
