Bug ID: 105391
Summary: gm2 doesn't heed --with-gmp*
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
When building the current devel/modula-2 branch on i686-pc-linux-gnu for
comparison's sake, the build failed like this
In file included from
/vol/gcc/src/hg/master/modula-2/gcc/m2/mc-boot/GAssertion.c:29:
/vol/gcc/src/hg/master/modula-2/gcc/system.h:702:10: fatal error: gmp.h: No
such file or directory
702 | #include <gmp.h>
| ^~~~~~~
compilation terminated.
and many many more similar errors. The system in question hadn't installed
gmp.h in system directories, but only in a separate prefix specified with
--with-gmp. However, gcc/m2/Make-lang.in doesn't heed GMPINC/GMPLIB.
The attached patch fixes this by adding $(INCLUDES) in many places. It was
enough
to let the build succeed, but is certainly hacky in that it may add the
variable
in more places than necessary. I found the makefile extremely hard to deal
with
because it's extremely repetitive.
