Hello John,

according to the configure script you have a gcc, but it fails to
compile with "-fPIC -O3"
checking for gcc... gcc
checking whether the C compiler (gcc -fPIC -O3 ) works... no
configure: error: installation or configuration problem: C compiler
cannot create executables.
Unable to configure Singular.
Command exited with non-zero status 1
Could you try compiling hello world or some or simple C program with
the same options and see if anything pops up? The autoconf run of
Singular also leaves a log around. There you should find the exact
failure why that config test failed.
