So I've installed Parallel Studio XE on my Ubuntu machine, and following the 'Get Started with...' file in the documentation, I've initialised the tools using 'source psxevars.sh', so all well and good so far.
This is only temporary, however, since if I actually want to use any of these compilers I have to 'initialise the tools' each time I start a new terminal.
Typing 'which gcc' returns /usr/bin/gcc (which is on the PATH), while 'which icc' returns a location inside /opt/intel/...
Is the simple solution here just to add the results of 'source psxevars.sh' to the PATH permanently?
Generally you should not want to do this. Reason, Intel, as well as other software companies, produce updates. When this happens, it is recommended that you do not "burn your bridges" so to say and throw out the prior release. IOW you would be advised to build with older version as well as newer version such that you can perform integrity tests, as well as performance tests between both versions. At some point later, if you desire, you can delete/uninstall the older version(s).
Thanks for getting back to me. So if it's not recommended to keep them on the path, I assume I have to perform the initialisation step every time I start a new terminal... unless I just use an IDE?
