Dear Rich,

I just tried installing GYRE 5.0, and I encountered a compilation error which I copy-paste below.
I have to mention that I use the MESASDK released on Feb 2015.
With an older (July 2014) sdk, and on a linux machine, I have exactly the same problem.

Best regards,
Ehsan.

For the current SDK:

Code: Select all

(mycond)cannon:gyre5.0 ehsan$ gfortran --version
GNU Fortran (GCC) 4.9.3 20150202 (prerelease)

and for the error:

Code: Select all

Hi Ehsan --

I think you need to upgrade to a more-recent SDK -- specifically, one which includes gfortran 5.3. Older versions of the compiler run into internal compiler errors (basically, a bug in the compiler).

cheers,

Rich

Thanks Rich for your pointer. I just updated my sdk to THE latest, and succeeded to compile GYRE 5.0. However, on my Linux machine, there are zillions of identical warnings on the terminal, which I basically ignored. Shall I worry about it?

Code: Select all

Determining dependencies
Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\G{ <-- HERE \s*([a-zA-Z_]\w*)\s*}/ at /STER/ehsan/mesasdk/bin/fpx3 line 233.

I have to mention though that the installation on my Mac went very clean, and no such warnings popped up.

Regards,
Ehsan.

Hi Ehsan --

This is in fact caused by some outdated Perl constructs in the fpx3 pre-processor which ships with the SDK. Nothing to worry about!

cheers,

Rich
