NB: I repeatedly checked the installation of Xcode, and the Xcode Command Line Tools, but the error seems not to be due to that, but the problem seems not to be resulting from there. This seems to be similar to ticket #62226 -- I take it from the answer there that this warning should be ignored for now.

Could be #61488. Please attach the log.

logfile for the aborted installation of cloog

[clegra]

Apologies for not having immediately added the log file. I attached it now. Thanks for the reminder.

The reason for my ticket was: the aborted build of cloog prevented regular "sudo port upgrade outdated" for all macports for me for more than a month now. I recognized that and now wanted to ask for help to get to the bottom of that. After your reaction I uninstalled "cloog" (all 3 versions I had), and executed the "port upgrade outdated" command again. Then now all port upgrades that happened in the meantime have been installed (about which I am happy for now).

I had hoped that also the cloog problem would go away, but it hasn't for now.

But many thanks for your help.

Not #61488, it's missing some includes:

:info:build source/isl/domain.c:63:9: error: implicit declaration of function 'isl_set_copy_basic_set' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
:info:build         bset = isl_set_copy_basic_set(set);
:info:build                ^

Don't hesitate to file a ticket if a port is failing to build and there isn't a ticket covering that already. But it is very important to supply a log, because without one, there's nothing to go on when investigating the problem.

Thanks very much, Joshua. In addition to the logfile here from which you cite (thanks!) I supported ticket #61883 for a libgcc7 build error, which I experienced later yesterday, by a zipped log-file. Thanks again for now & kind greetings.

Yes, you have to add the missing includes so that it can find the functions. I'll take a look and try to submit a fix if I can get it to build.

The issue still persists, even after running selfupdate. Am I missing any steps? Should I try building from the source?

cloog: depend on compatibility version of isl

CLooG relies on function that no longer exist in isl.
