OpenBLAS: libgcc not found

[amadeus24]

Hi,

it seems the problem starts here:

:info:build ld: library not found for -lgcc_ext.10.5

See the attached log-file.
Thanks

Can you do the following:

sudo port clean openblas
sudo port selfupdate
sudo port install openblas

Hopefully that will take care of the issue.

arrack config.log

arpack config.log

Thanks for instructions.
Did that and OpenBLAS was installed, but I end-up in a problem with arpack and OpenBLAS is recognised as a broken port.
After OpenBLAS was installed, a rev-upgrade process started:

--->  Scanning binaries for linking errors
--->  Found 52 broken files, matching files to ports
--->  Found 7 broken ports, determining rebuild order
You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt:
 arpack @3.7.0+accelerate+gfortran
 libgcc7 @7.4.0
 libgcc6 @6.5.0
 gcc5 @5.5.0
 pdftk @2.02+gcc5
 OpenBLAS @0.3.6+gcc9+lapack
 VLC @3.0.6+quartz

Sorry, accidentally I have submitted the arpack config-log x 2.

Does installing or updating libgcc9 as suggested ​here help?

Thanks! This did solve the issue.
