gdb-apple is also affected by the debug register naming issue.

gdb-apple will be your best bet. It looks like it just needs the register fields renamed and then will build successfully.

Replying to Cebtenzzre:

gdb-apple is also affected by the debug register naming issue.

Apple changed the register names in the Leopard SDK and newer. As all software uses the new names, many builds fail on Tiger for this reason.

I like the way Jeremy fixed it in the ld64 port, but they can be patched individually with a patchfile as well:

​https://github.com/macports/macports-ports/blob/0dce830ca5a4308f470eb99d6111f677a324ea3c/devel/ld64/Portfile#L470

I've posted a version update to gdb-apple with an attempted i386 fix here: ​https://github.com/macports/macports-ports/pull/18662

[evanmiller (Evan Miller)]

In 605e61ff2dee710c2ed9d22315417b0b716c3672/macports-ports (master):

gdb-apple: update to 2831

Closes: #67370
