Bug ID: 18294
Summary: gdb compilation fails on 32-bit Solaris: largefile vs.
procfs
Product: gdb
Version: 7.9
Status: NEW
Severity: normal
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: ro at TechFak dot Uni-Bielefeld.DE
Host: i?86-*-solaris2*, sparc-sun-solaris2*
Target: i?86-*-solaris2*, sparc-sun-solaris2*
Contrary to gdb 7.8, 7.9 fails to compile on 32-bit Solaris:

In file included from /vol/src/gnu/gdb/gdb-7.9/gdb/i386-sol2-nat.c:23:0:
/usr/include/sys/procfs.h:24:2: error: #error "Cannot use procfs in the large
file compilation environment"
make: *** [i386-sol2-nat.o] Error 1
I could track this down as follows:
* before, gdb/config.h didn't define _FILE_OFFSET_BITS, now it has
#define _FILE_OFFSET_BITS 64
* in gdb 7.8, the `checking for special C compiler options needed for large
files'
tests in gdb/configure weren't run at all since they were guarded by
test "$enable_largefile" != no
* enable_largefile was set to no in config/largefile.m4
* in gdb 7.9, the default for $plugins changed from its previous no, so
suddenly
the largefile support gets enabled again, breaking the gdb build
