Hi there !
I'm pretty impressed by the new functionalities of GDB 7.0, which
works pretty well on my Linux box. But, I've some problem with the
darwin version.
I currently use an iMac under darwin 10 (Snow Leopard).
First of all, it seems that the dyld struct used by gdb to catch dylib
loading have changed: the version number was 1 under darwin 9, and is
now 7. So, commands like "info sharedlibrary" do not work unless I
change the DYLD_VERSION macro definition in gdb/solib-darwin.c file.
By the way, by changing the definition on DYLD_VERSION and by testing
everywhere in the code that version is less or equal to 7, I finally
got gdb reading symbols of my dylib files correctly !
But now, I've another problem: it seems that GDB do not handle
coalesced sections, so symbols address are mostly wrong for functions
defined in a header file. Did I missed something in arguments to give
to configure script ?
I used :
./configure --disable-werror
I already tried "--host=i386-apple-darwin9 --build=i386-apple-darwin9
--target=i386-apple-darwin9"
Note that I only want to debug 32 bits applications, so I do not used
--enable-64-bit-bfd, but this switch do not change anything in MachO
loading.
Thank you
