From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rainer Orth To: gdb-patches@sources.redhat.com Subject: 5.1 PATCH: Allow gdb to link on mips-sgi-irix5.3 Date: Thu, 26 Jul 2001 14:42:00 -0000 Message-id: <15200.36561.946734.92731@xayide.TechFak.Uni-Bielefeld.DE> X-SW-Source: 2001-07/msg00662.html I just tried the current CVS version, configured on IRIX 6.2 for mips-sgi-irix5.3, to allow debugging O32 binaries on IRIX 6 during my work to re-integrate O32 ABI support for IRIX 6 into GCC. gdb failed to link, though: ld32: ERROR 33 : Unresolved text symbol "no_shared_libraries" -- 1st referenced by libgdb.a(remote.o). The patch below fixes this. Unfortunately, the resulting gdb does not work at all: * Trying to debug a trivial hello world compiled with cc -32 -g (i.e. with mdebug debugging information) lets gdb abort with an internal error: % cc -32 -g -o hello-cc hello.c % gdb/gdb ./hello-cc GNU gdb 2001-07-26-cvs (MI_OUT) Copyright 2001 Free Software Foundation, Inc.
