Patch if Intel's shitty installer cant find libraries, but they are presents

vtune-amplifier-install.md

If you cannot install Intel VTune Amplifier on Manjaro/Arch Linux (or other non-supported OS), because this shit cannot find installed libraries via ldconfig -p, you can use this script.
Unpack vtune_amplifier_2019_update3.tar.gz, then go to vtune_amplifier_2019_update3, then copy and paste following:

shopt -s globstar

for i in **/sysreq.cab; do
    echo "processing ${i}"
    perl -pi -e 's/(\W*)RESULT=255(.*)/\1RESULT=1  \2/' "${i}"  # COMPARE_VERSIONS() never returns 255
    perl -pi -e 's/(\W*)LI_(.+)=unsupp(.*)/\1LI_\2=ok    \3/' "${i}"
    perl -pi -e 's/(\W*)LI_(.+)=not_detected(.*)/\1LI_\2=ok          \3/' "${i}"
    perl -pi -e 's/(\W*)LI_(.+)=not_found(.*)/\1LI_\2=found    \3/' "${i}"
done

for i in **/amplifier.cab; do
    echo "processing ${i}"
    perl -pi -e 's/(\W*)LI_(.+)=unsupp_cpu(.*)/\1LI_\2=ok        \3/' "${i}"
    perl -pi -e 's/(\W*)LI_(.+)=non_intel_cpu(.*)/\1LI_\2=ok           \3/' "${i}"
    perl -pi -e 's/(\W*)LI_(.+)=cpu_check_fail(.*)/\1LI_\2=ok            \3/' "${i}"
    perl -pi -e 's/(\W*)LI_(.+)=nok(.*)/\1LI_\2=ok \3/' "${i}"
    perl -pi -e 's/(\W*)    LI_(.+)=virtual(.*)/\1LI_\2=non_virtual\3/' "${i}"
    perl -pi -e 's/(\W*)LI_(.+)=not_found(.*)/\1LI_\2=found    \3/' "${i}"
    perl -pi -e 's/(\W*)LI_(.+)=unsupp(.*)/\1LI_\2=ok    \3/' "${i}"
done

It will patch CLI and GUI install scripts. Nothing more. Find and replace.
Also: prerequirements' warning Unsupported OS can be ignored.
Parallel Studio XE may be patched same way (unchecked).

VTune Amplifier is now FREE

Thanks, it did the trick. No idea how I would have solved this otherwise.
They still didn't fix this in update 5.

They still didn't fix this in update 5.

And never will... I had reported issue, their answer was: we do not support your OS.
Also you can try rpmextract, but I am not sure if it will work, because some of their bash scripts have template variables like prefix directory.
AFAIK they wanted OneAPI for their products in 2020, I am not sure it turns positive way.

It seems to have worked for me with 2020 update 1. I needed only

perl -pi -e 's/(\W*)LI_(.+)=not_found(.*)/\1LI_\2=found    \3/' "${i}"

for both sysreq.cab and amplifier.cab. The crucial change is that the above version replaces not_found to ok in sysreq.cab, but found is needed instead.

Fixed this, thanks pseyfert
