Unable to update gmp

[mikemadden42@…]

I'm using the following commands to update my ports, but I'm running into an issue updating gmp.

sudo port selfupdate 

sudo port outdated

sudo port upgrade outdated

The ports tree has been updated. To upgrade your installed ports, you should run
  port upgrade outdated
The following installed ports are outdated:
gmp                            6.0.0_0 < 6.0.0_1         
gnutls                         3.3.7_0 < 3.3.8_0         

$ sudo port upgrade outdated

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

This is not a clean build log. Please clean the port and try again. Then attach the new main.log file.

The following error shows up frequently in your log:

error: couldn't create cache file '/var/folders/h6/3f7lvmw96_jbw0w9tmn54rph0000gq/T/xcrun_db-GObdiH4N' (errno=Permission denied)

Are you out of disk space?

These clang errors are actually errors but they fail to terminate compilation like they should. Clang miscompiles code when this happens (as in your example). A workaround is usually to outright delete the offending folder (i.e. /var/folders/h6/3f7lvmw96_jbw0w9tmn54rph0000gq in your case). Then clean and try again.

This happens because the folder gets created as root, but MacPorts subsequently tries to use it as the macports user, which consequently fails afterwards. We're just not sure *where* MacPorts is calling the compiler as root, or we would have fixed it.

Doing the following has fixed the issue I'd seen upgrading gmp:

sudo rm -rf /var/folders/h6/3f7lvmw96_jbw0w9tmn54rph0000gq
sudo port clean gmp && sudo port upgrade outdated
