Bug ID: 101387
Summary: Unconditional use of <sys/cdefs.h>
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: gaiusmod2 at gmail dot com
Target Milestone: ---
Target: *-*-solaris2.11
When I tried to build the devel/modula-2 branch as of 20210708 on Solaris 11
(both SPARC and x86), the build failed early with
/vol/gcc/src/git/modula-2/gcc/m2/mc-boot/GRTExceptions.c:42:13: fatal error:
sys/cdefs.h: No such file or directory
# include "sys/cdefs.h"
^~~~~~~~~~~~~
compilation terminated.
make[3]: *** [/vol/gcc/src/git/modula-2/gcc/m2/Make-lang.in:1579:
m2/mc-boot/GRTExceptions.o] Error 1
<sys/defs.h> (preferably with <> rather than "") originates from *BSD, I
believe
and is certainly not universal.
sys/defs.h also emitted in gcc/m2/mc/keyc.mod, mc-boot/Gkeyc.c
To hack around this, I've disabled/commented the header in the affected files
with no apparent ill effect.
