Question about GDB bindings and 32/64 bits
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have installed GDB 7.2 32 bits and 32 bits buildslaves are green. Nevertheless 64 bits buildslaves are failing test_gdb. Is there any expectation that a 32 bits GDB be able to debug a 64 bits python?. If not, gdb test should compare "platform.architecture()" (for python and gdb in the system) and run only when they are the same. If this should work, I would open a bug and maybe spend some time with it. But before thinking about investing time, I would like to know if this mix is actually expected or not to work. If not, I would consider to install a 64 bits GDB too and do some tricks (like using an "/usr/local/bin/gdb" script wrapper to choose 32/64 "real" gdb version) to actually execute "test_gdb" in both buildslaves (they are running in the same physical machine). Any advice? PS: I am talking about AMD64 OpenIndiana buildbots. Haven't check others. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea@jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/_/_/_/ . _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBTO8zjJlgi5GaxT1NAQLusgP9GVuhvQJWhPqjzdkZnrMObQg0AD6ggbIR 2B4IstFpD1bKvIcGPJv0Irk3+heaQuFbTzYVLC132d89Ektfib9ZbJ/hzJz2wqd2 lnkfNUCV0tKal3P7kbGYUk828glIrlufSuF1HYIknd2BAzHFl5Zf6q5/AXzYr90D v4Y82b7Wg0k= =NHcR -----END PGP SIGNATURE-----

that would be too restrictive, as an 64bit gdb is able to handle 32bit binaries too.
If this should work, I would open a bug and maybe spend some time with it.

yes, and then you should be able to use this gdb for both 32 and 64bit builds. No need for a wrapper (Such a gdb is available in the gdb64 package on Debian/Ubuntu). Matthias

I compiled GDB 64 bits to debug both 32 and 64 bits binaries. There are some thread debugging issues when debugging 32 bits, but we can live with them for now. Details in <http://bugs.python.org/issue8600#msg131073>. Thanks for the suggestion, Matthias.
