gmp pre-configure fails with "couldn't create error file for command"

[mgs0lid_sn4ke@…]

Hi,

I used macports in the past on this laptop and it worked fine. I had to reinstall it for several reasons. I am know in the process of reinstalling all the package I need.

I tried to run

sudo port install gmp

and I got the following output :

sudo port install gmp
Password:
--->  Configuring gmp
Error: org.macports.configure for port gmp returned: couldn't create error file for command: permission denied
Please see the log file for port gmp for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_gmp/gmp/main.log
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets
Error: Processing of port gmp failed

I don't know why it says "permission denied" since i am using sudo.

can you help with this issue please ?

Thanks in advance.

Best, Thomas

The error comes from the configure phase, which usually runs as an unprivileged user.

:notice:configure --->  Configuring gmp
:debug:configure Using compiler 'Xcode Clang'
:debug:configure Executing proc-pre-org.macports.configure-configure-0
:error:configure org.macports.configure for port gmp returned: couldn't create error file for command: permission denied

I’ve never seen this failure before, and I don’t know what this “error file” is.

Yes you are using sudo, but MacPorts drops privileges to an unprivileged "macports" user. gmp's pre-configure block runs exec. According to my Google search, the error message can occur when exec tries to create a temporary file but does not have permission to do so, because the tmp directory is not world writable. The question is: which tmp directory—/tmp, /var/tmp, something in /var/folders? MacPorts creates a .tmp directory in the work directory, but Tcl might be using a different one; certainly the MacPorts-created one should have correct permissions. We've seen other errors before due to tmp directories in /var/folders mysteriously having wrong permissions, which were resolved by removing the offending directory and letting the system recreate it, possibly following a restart.

I can only assume config.guess is doing something that fails. I’ve addressed one possible failure mode in r129028, but I don’t know if that is actually your problem.

The new portfile r129028 did the job for gmp. Thanks. But i'm still having trouble with other ports. I tried to install gcc49 and during the installation of ld64, I go tthis output :

--->  Building ld64
Error: org.macports.build for port ld64 returned: command execution failed
Please see the log file for port ld64 for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_ld64/ld64/main.log
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets
Error: Processing of port ld64 failed

But I may need to open another ticket for this.

Yes please.
