Milestone Port Bugs deleted

[ryandesign (Ryan Carsten Schmidt)]

I disabled the universal variant for now in r56930. If you can figure out how to make it work, please reenable.

[ryandesign (Ryan Carsten Schmidt)]

in progress attempt to make llvm universal

[ryandesign (Ryan Carsten Schmidt)]

Using the attached patch​ using the muniversal portgroup gets close to allowing a universal build, but the llvm-config program differs between architectures, and I don't know how to resolve it.

[israfel33@…]

Following seems to work:

port configure llvm
cd `port dir llvm`
cd work/build
sudo make UNIVERSAL=yes UNIVERSAL_ARCH="i386 x86_64"
sudo make install

Do not know how to do this using configure flags :-(

Cc Me!

[smokris (Steve Mokris)]

israfel33@…'s instructions above aren't working for me (perhaps something has changed in the year that's elapsed since that comment). It builds for about an hour, then says:

make[2]: *** No rule to make target `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_llvm/work/llvm-2.8/Release/lib/libLLVM-2.8.dylib', needed by `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_llvm/work/llvm-2.8/Release/bin/opt'.  Stop.

(I'm not sure offhand how to further troubleshoot this.)

[ryandesign (Ryan Carsten Schmidt)]

Replying to israfel33@…:

sudo make UNIVERSAL=yes UNIVERSAL_ARCH="i386 x86_64"

Yes, this seems to be ​how Homebrew is doing it now and ​how macruby recommends compiling it.

Replying to smokris@…:

make[2]: *** No rule to make target `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_llvm/work/llvm-2.8/Release/lib/libLLVM-2.8.dylib', needed by `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_llvm/work/llvm-2.8/Release/bin/opt'.  Stop.

Yes, this seems to be ​reported in llvm's issue tracker as well. I get it too.

I'll attach a patch of my new update attempt so far.

[ryandesign (Ryan Carsten Schmidt)]

new unfinished patch

[larryv (Lawrence Velázquez)]

Assuming this is no longer relevant. We don’t even have an llvm port anymore.

[ryandesign (Ryan Carsten Schmidt)]

Indeed:
