Description
On Big Sur/arm64, installing gdb results in unwanted reinstallation of all dependencies with the +universal variant
port install gdb ---> Fetching archive for libiconv ---> Attempting to fetch libiconv-1.16_1+universal.darwin_20.arm64-x86_64.tbz2.rmd160 from https://mse.uk.packages.macports.org/libiconv ---> Installing libiconv @1.16_1+universal ---> Cleaning libiconv ---> Deactivating libiconv @1.16_1 ---> Cleaning libiconv ---> Activating libiconv @1.16_1+universal ---> Cleaning libiconv ---> Fetching archive for ncurses ---> Attempting to fetch ncurses-6.2_1+universal.darwin_20.arm64-x86_64.tbz2 from https://mse.uk.packages.macports.org/ncurses
.... and so forth for all dependencies boehmgc, expat, gettext, libiconv, ncurses, zlib

| Resolution: | → wontfix |
|---|---|
| Status: | new → closed |
gdb has been fixed by several commits to build the x86_64 version properly on Ventura, including building the x86_64 version transparently on an M1 Mac.
however, gdb upstream does not support arm64 MacOS at present:
<https://inbox.sourceware.org/gdb/1BD161F9-A6BB-4682-AD39-7698D56F0BB0@comcast.net/>
so there is nothing in MacPorts to request, until upstream has something to build.

Replying to kencu:

Do we have some alternative, working debugger on aarch64?

lldb works well, fully supported by Apple, current OS support right up the minute.

Herę is repo where you can download gdb compiled for aarch64: https://github.com/SeanMollet/arm-none-eabi-gcc-aarch64-macosx There are also instructions and necessary patches to compile it yourself

Hmm, I am not experienced with port recipes, but it seems that https://github.com/SeanMollet/arm-none-eabi-gcc-aarch64-macosx provide patch files. So why close this as #wontfix if one could IMHO follow those instructions also in a port recipe: require dependencies, pull gdb source code, pull patches, apply patches, build?

upstream gdb doesn't support arm64 mac yet.
homebrew doesn't have it for arm64 either, naturally
Yes -- some guy somewhere put some patches in a personal git repo three years ago and says they make gdb work.
Well -- have at it. That is just not something a project like macports should be hacking into.
Soon enough, I hope, gdb will officially support arm64 macos. Please work on pressuring them, rather than us, as that would be the Right Thing To Do.
This is because gdb sets
supported_archs x86_64 i386. On an Apple Silicon system, that means that gdb will be built as x86_64, and thus all dependencies need to be universal.I'll leave this open as a request to add native arm64 support.
