From: "employee at live dot com" <sourceware-bugzilla@sourceware.org> To: gdb-prs@sourceware.org Subject: [Bug gdb/16669] New: Bad configure under gdb subdirectory of source in tarball http://ftp.gnu.org/gnu/gdb/gdb-7.7.tar.gz Date: Fri, 07 Mar 2014 06:02:00 -0000 [thread overview] Message-ID: <bug-16669-4717@http.sourceware.org/bugzilla/> (raw) https://sourceware.org/bugzilla/show_bug.cgi?id=16669 Bug ID: 16669 Summary: Bad configure under gdb subdirectory of source in tarball http://ftp.gnu.org/gnu/gdb/gdb-7.7.tar.gz Product: gdb Version: 7.7 Status: NEW Severity: critical Priority: P2 Component: gdb Assignee: unassigned at sourceware dot org Reporter: employee at live dot com Created attachment 7458 --> https://sourceware.org/bugzilla/attachment.cgi?id=7458&action=edit gdb 7.7 ./gdb/acinclude.m4 ./gdb/configure contains apparently problematic macros under # Add ELF support to GDB, but only if BFD includes ELF support. after recent changes to ./gdb/acinclude.m4 (Jan, 4, 2014) The problem is perhaps due to incorrect expension of macros, as the following section in ./gdb/acinclude.m4 of GDB 7.7 package is possibly to cause configure to ignore elf support provided by bfd: if test "$plugins" = "yes"; then AC_SEARCH_LIBS(dlopen, dl) fi while in GDB 7.6 the relevent lines of "(GDB_AC_CHECK_BFD) New macro" is defined as such: if test "$plugins" = "yes"; then LIBS="-ldl $LIBS" fi As a consequence for gdb to miss the check on elf support that is in fact provided by bfd, it is confirmed with i386-pc-linux-gnu, but not limited to, that gdb program can't read symbol by output: Reading symbol from {exe}...I'm sorry, Dave, but I can't do that. Symbol format "elf32-i386" unknown. Possible solution for end-user is to revert above lines of macro in acinclude.m4 in ./gdb back to those in tarball of gdb 7.6. -- You are receiving this mail because: You are on the CC list for the bug.
