I just upgraded to El Capitan and found out that the C compiler (Clang) is not working under the command line. I wrote a "hello word" test, tried to compile and I get the following error:
$ cc test.c -o test
error: unable to open output file
'/var/folders/Ge/GeRStfi8Ek8jojLcqf1vsE+++TI/-Tmp-/test-ad7039.o': 'No
such file or directory'
1 error generated.
... do I have a permission problems somewhere? Thanks!
It is indeed a permission problem as I can actually compile the file using sudo; I tried repairing manually the permissions using the command line with:
sudo /usr/libexec/repair_packages --verify --standard-pkgs /
and
sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume /
but still I cannot compile without the sudo command
Well, that’s weird. If I were in your situation I’d debug this as follows:
start up a VM running 10.11
run my test in the VM to verify that things work there
for each directory in the error path, compare the permissions in the VM against the permissions on my Mac
Share and Enjoy
