I cannot build g95

[manulcaux]

In my way to upgrade my mac port installation after migrating my whole environment from one MacBook Pro to a new MacBook Pro Touchbar, i cannot upgrade g95 with the following error. I report here the full error after having cleaned g95, uninstalled it and reinstall it, the error is still the same :

I tried to find something in this file, but didn't succeed.

I am running Mac OS Sierra 10.12.4, updated successfully my MacPort installation, and all my softs installed via MacPort I think, having not seen other errors but this one.

In the future, please use WikiFormatting, fill in the Port field and Cc the port maintainers (port info --maintainers g95), if any.

[ryandesign (Ryan Carsten Schmidt)]

Please attach the main.log file; without it, we cannot know why it failed to build.

Hi,

As requested, I attached the relevant file. Please note I just made some tries and still have the error.

Hi, in the hope that the following is useful...

There are two other tickets reporting the same problem, #54109 & #54155.

The problem seems to be simply that two comments at the beginning of the file libf95/math/x87.S which start with "##" are being mis-intrepretted somehow and producing "unexpected token at start of statement" errors.

The two lines are:

## Some of the code here is transliterated from the x87 glibc code ## originally written by J.T. Conklin and Ulrich Drepper.

If one simply encloses these in /* ... */ the problem (appears) to be solved, i.e.

/*

## Some of the code here is transliterated from the x87 glibc code ## originally written by J.T. Conklin and Ulrich Drepper.

*/ I can provide the modified Portfile and the patch file which implements this fix.

Best regards

John Pritchard

Ooops, forgot to "code block" the code bits...

The two lines are:

## Some of the code here is transliterated from the x87 glibc code
## originally written by J.T. Conklin and Ulrich Drepper.

If one simply encloses these in /* ... */ the problem (appears) to be solved, i.e.

/*
## Some of the code here is transliterated from the x87 glibc code
## originally written by J.T. Conklin and Ulrich Drepper.
*/

I can provide the modified Portfile and the patch file which implements this fix.

Hi John,

Many thanks for the help.

What I understand is that I can make the change on my computer, but it would be more useful to do it at a higher level, and this is what you propose ? Can you confirm please ?

Cheers,

Hi John and Manu,

I reported the ticket #54155 with the same problem, and I solved it just like you said, John. I opened the file x87.S using

sudo vim x87.S

And then enclosed the first and second lines with /* --- */. After the edition was made, I executed

sudo port install g95

And it build it! Thank you very much for your help!

Cheers,

Alvaro

Hi Manu,

Sorry for the delay in replying, I was waiting for email notifications which never came, probably I have to turn something on somewhere.

Anyway. Indeed it seems you can just try to install it. Let it fail. Then edit the relevant file, then retry the installation command ("sudo port install g95") as indicated by Alvaro. I didn't do it like this though, I created my own custom version of the Portfile and a corresponding patch file (just by copying the original g95 Portfile and files directory and making the required modifications) and then installed that Portfile. If you are still looking for the answer you can try this:

cd $HOME
ftp http://www.eso.org/~jpritcha/g95/g95.macports.tgz
tar -zxvf g95.macports.tgz
cd lang/g95/
sudo port install
cd ../..
rm -fr lang/g95
rmdir lang
rm g95.macports.tgz
sudo port install g95

Hope that helps you out.

Cheers John
