Hello!

Welcome to the VASP forum! It seems you are using a rather old version of the GNU compiler. As far as I know -fallow-argument-mismatch was introduced in version 10 but -ffpe-summary dates back to 4.9. Can you please check which compiler version you are using by executing
Can you try to remove both command line options from the makefile.include file and check whether it is then possible to compile the code? If that does not work and your compiler is old (< 7.5) I would recommend to update the compiler first, maybe there is some extra repositories for CentOS from which you can retrieve updated versions. Note: GCC 8 is not compatible with VASP.

Hello!

It seems you are missing some functions from LAPACK during the linking stage. Can you please post the contents of your makefile.include file and post the output of

Hello
Thank you so much.
I have changed again make include file as per guide line, after change make.include file the command make DEPS=1 -j executed without error.
After execution above command I have run "make test_all" command and I am getting following warning

ALGO = GW0 will be deprecated in future releases. Please use ALGO = EVGW0 from now on.

please advise.

Hello!

Ok great! No need to worry about this warning message, as long as your testsuite passes with at the very end of testsuite/testsuite.log everything is fine!
