thanks for the hint! ok, so here are some more problems at least FYI,
not sure if all of them can and must be fixed ?!
with no specific order:
-------------------------------------------------------------------------------
SGI IRIX:
cc-1028 cc: ERROR File = gdb-CVS-20100222/gdb/varobj.c, Line = 1703
The expression used must have a constant value.
varobj_update_result r = {*varp};
^
using "gcc -pedantic" you'll get at least a warning about this problem:
gdb-CVS-20100222/gdb/varobj.c:1703: warning: initializer element is not computable at load time
gdb-CVS-20100222/gdb/varobj.c:1711: warning: initializer element is not computable at load time
gdb-CVS-20100222/gdb/varobj.c:1741: warning: initializer element is not computable at load time
gdb-CVS-20100222/gdb/varobj.c:1818: warning: initializer element is not computable at load time
gdb-CVS-20100222/gdb/varobj.c:1828: warning: initializer element is not computable at load time
gdb-CVS-20100222/gdb/varobj.c:1855: warning: initializer element is not computable at load time
a possible fix for the 1st error would be varobj.c.diff (attached).
-------------------------------------------------------------------------------
old bison/yacc:
on some older linux I run into this problem:
c-exp.y:2238: error: field 'value' has incomplete type
these are the distros and bison/byacc versions:
suse 9.0 bison 1.75
redhat 9 bison 1.35
centos 5.0 byacc-1.9-29.2.2
the attached patch c-exp.y.diff seems to work both with bison-2.3 and
those older versions...
-------------------------------------------------------------------------------
Solaris
on solaris 5.8 (sparc, Sun C 5.7 2005/01/07) and 5.10 (sparc Sun C 5.8 2005/10/13 and x86 Sun C 5.9 SunOS_i386 Patch 124868-01 2007/07/12) the cc complains about unknown __FUNCTION__ :
"gdb-CVS-20100222/bfd/elfxx-sparc.c", line 2944: undefined symbol: __FUNCTION__
and
"gdb-CVS-20100222/bfd/elf32-i386.c", line 1406: undefined symbol: __FUNCTION__
"gdb-CVS-20100222/bfd/elf32-i386.c", line 3012: undefined symbol: __FUNCTION__
the short hack in bfd.diff is far from being perfect, just an example
how to get it compiling because
(a) it should check for C99 and/or solaris (e.g. if __func__ is really available -- looks like a autoconf thingy;)
(b) this check/define should be handled elsewhere at one central place
as there are more files "affected" :
gdb-CVS-20100222 > grep -rl __FUNCTION__ .
./bfd/elfxx-sparc.c
./bfd/bfd-in2.h
./bfd/nlm32-sparc.c
./bfd/elf64-x86-64.c
./bfd/elf32-i386.c
./bfd/elf32-bfin.c
./bfd/bfd-in.h
./sim/cris/traps.c
./gdb/ChangeLog-2004
./gdb/ChangeLog-2002
./gdb/ChangeLog-2000
as the ChangeLogs tell that's not really a new problem, IMHO I'd go with ./gdb/ChangeLog-2000 ;-))
./gdb/ChangeLog-2000: * uw-thread.c: Remove __FUNCTION__ GNUism.
./gdb/ChangeLog-2002: __FUNCTION__.
./gdb/ChangeLog-2002: * gnu-nat.c (do_mach_notify_no_senders): Replace __FUNCTION__ with
./gdb/ChangeLog-2004: * ia64-tdep.c (ia64_find_proc_info_x): Do not use __FUNCTION__.
-------------------------------------------------------------------------------
AIX 5.3
just FYI: while gdb 7.0.1 crashes when trying to start a program
(typing "gdb a.out" and "r" will SIGSEGV)...
gdb 7.1.50.20100222-cvs seems to work, at least running and simple break points work...
