cannot install OpenBLAS

[manulcaux]

Trying to install OpenBLAS after having ran sudo port self update and sudo port upgrade outdated failed with the error in the attached file.

I also tried to make a sudo port clean OpenBLAS, followed by a sudo port install OpenBLAS, as well as a sudo port uninstall OpenBLAS followed by a sudo port install OpenBLAS, all with the same error.

Thanks

as you can see, it looks like your particular installation of ld64 was built against llvm-3.9, but that has now been deprecated, and the llvm-3.9 libraries no longer exist, ergo your error.

:info:build compilation terminated.
:info:build dyld: Library not loaded: /opt/local/libexec/llvm-3.9/lib/libLTO.dylib
:info:build   Referenced from: /opt/local/bin/ld
:info:build   Reason: image not found

I believe you should most easily fix your troubles if you do this:

sudo port -f uninstall ld64
sudo port -v install ld64

that should give you a working ld64.

and then try your OpenBLAS build again.

Indeed, this did the job, everything seems OK now.

Many thanks !
