Considering as replacement for libelf on macOS #103251

[cho-m]

Currently chose to link on macOS and keep keg-only on Linux. All packages that may conflict:

• binutils - keg-only on macOS
• elfutils - Linux-only
• libelf - deprecated and planning to disable/remove soon
• mono - due to msc binary, but I added workaround to only install into libexec and not link to bin. Alternatively, could just mark conflict.
• dwarfutils - only maintained formula that actually conflicts in current state.

---

Another option is to install libelf*/libdwarf* into a subdirectory like LIBDIR=#{lib}/#{name} which may remove conflict with libelf & dwarfutils, but this may make it trickier to use by dependents/users as may need to manually add LDFLAGS and update RPATH

Is there a PROGRAM_PREFIX argument we can use? That seems to make more sense since the binaries that ship with this formula are meant to work on ELF files, so they're not exactly equivalent to the system-provided ones (which is the case for your typical keg-only/unlinked binaries).

[cho-m]

I didn't see anything that we can easily use.

MacPorts manually does this (i.e. mv cmd to elftc-#{cmd} and symlink into libexec/elftoolchain/#{cmd}) and also uses subdirectories (e.g. lib/elftoolchain, include/elftoolchain, ...) to avoid conflicts https://github.com/macports/macports-ports/blob/master/devel/elftoolchain/Portfile#L69-L78

The above would allow us to remove all conflicts/keg-only while having main files installed into linked directories.

Another option is to install binaries under libexec/... and just symlink to bin/SOMEPREFIX-#{cmd} (e.g. either elftc-ar like MacPorts or full name like elftoolchain-ar).

[carlocab]

Fine with doing any of that.

[carlocab]

I'm ok to merge this as-is or after renaming the binaries to be prefixed with elf- or similar.

The draft formula feels like a pile of patches and hacks. I'd say either they can be upstreamed, or this does not feel stable at all.

[cho-m]

Closing for now. Still hoping for a new release.
