Installation error in Ubuntu 20.04 LTS

Hi,

I am trying to install openPBS on my Ubuntu 20.04 LTS system.
I typed the following commands in “openpbs” directory.

./autogen.sh
./configure -prefix=/opt/pbs
make

But the compilation process was halted with the error message shown below.

gcc -DHAVE_CONFIG_H -I. -I../../../src/include  -I../../../src/include    -g -O2 -MT libattr_a-attr_fn_acl.o -MD -MP -MF .deps/libattr_a-attr_fn_acl.Tpo -c -o libattr_a-attr_fn_acl.o `test -f 'attr_fn_acl.c' || echo './'`attr_fn_acl.c

What do I have to do to finish the compilation properly?

Remove the prefix and see. Try to build rpm and then install.
