SIerra: issue with assembler "as" in conjunction with gfortran

[rjones-sandia]

I've removed and reinstalled "port"

$ port version
Version: 2.5.3

I've only installed gcc7 at this point:

$ port installed

  zlib @1.2.11_0 (active)

and I'm still getting :

$ /opt/local/bin/gfortran-mp-7 test.f90 
FATAL:/opt/local/bin/../libexec/as/x86_64/as: I don't understand 'm' flag!

$ which as
/opt/local/bin/as

Not sure how to get around this with macports.

thanks Reese

btw removing /opt/local/bin from my PATH:

$ which as
/usr/bin/as
$ which gfortran
/usr/local/bin/gfortran
$ gfortran test.f90 
$ 

works

could you please give us the output of this command:

    echo "macOS $(sw_vers -productVersion) $(sw_vers -buildVersion)"; echo "Xcode $(xcodebuild -version | awk '{print $NF}' | tr '\n' ' ')"

and this command:

ls -la /opt/local/bin/as

thanks!

Thanks for the report. We are fine-tuning the assembler usage on the newest systems, and I suspect this will turn out to be another example of that.

You should re-install cctools. The +xcode variant is now the default. Using +llvm50 is know to cause problems.

Replying to mf2k:

The +xcode variant is now the default. Using +llvm50 is known to cause problems.

That is only true when Xcode 9 or later is installed. The user hasn't yet told us what version of Xcode they use.

Good point!

Hi

sorry for the delay, I didn't have access to the machine before now.

macOS 10.12.6 16G1510 Xcode 8.2.1 8C1002

$ ls -la /opt/local/bin/as -r-xr-xr-x 1 root wheel 28020 Aug 30 22:17 /opt/local/bin/as*

ok that bit of magic got me past a "hello world" f90 compile. thanks -- I'm trying the cross compile of the actual application. Reese
