Hi Jorge, Your config.log has these lines:
configure:10133: checking whether the C compiler works configure:10155: icx -DNDEBUG '-O3' conftest.c >&5 icx: error: no such file or directory: ''-O3'' configure:10159: $? = 1 configure:10199: result: no configure: failed program was: The problem seems to be that somehow the "-O3" you are using on the command line gets mangled into '-O3' for the compiler. The compiler doesn't understand that. Maybe try again without the CFLAGS, etc. being specified on the configure line? Also make sure to use CXX=icpx Otherwise the configure will fail somewhere else.

I am sorry, I did not have any luck with the suggestion. There are no significant changes. I have attached the new config.log.gz file. I suspect problems, perhaps, related to the symbolic link ln -s /usr/lib64/libgcc_s.so.1 /usr/x86_64-linux-gnu/lib/https://urldefense.com/v3/__http://libgcc_s.so__;!!Bt8fGhp8LhKGRg!BNmpId7wlYNL0cBzB6JFJoldka0u-PJ_-F6WoFuHDoHIUzLn-u6nJVNV1dRStKwE2uLT0Wp4XCiB8RoHLblR65I$ <https://urldefense.com/v3/__http://libgcc_s.so__;!!Bt8fGhp8LhKGRg!BNmpId7wlYNL0cBzB6JFJoldka0u-PJ_-F6WoFuHDoHIUzLn-u6nJVNV1dRStKwE2uLT0Wp4XCiB8RoHLblR65I$> . So, please, do you have any other suggestions? Regards, Jorge.
