Bug ID: 59979
Summary: mpc configure does not check for non-gnu compiler
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: fukanchik at gmail dot com
There is something called gcc in my system, but the real compiler is called
`cc'. GMP and MPFR are compiling fine. Configure scripts are able to detect the
correct compiler. MPC configure script does not look for something else but
gcc:
uname -a:
SunOS host 5.10 Generic_147441-20 i86pc i386 i86pc
Configure output (MPC):
checking host system type... i386-pc-solaris2.10
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: in `/cpp/mpc/mpc-0.8.1':
configure: error: C compiler cannot create executables
This is what happens in GMP (which builds successfully):
checking ABI=64
checking compiler gcc -O2 -pedantic -m64 ... no
checking compiler cc -xO3 -m64 ... yes
checking for gcc... cc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
