Change temporary directory used by go build

[Ignacio Grande]

Hi everyone.

It is possible to change the base temporary directory used by go build command?

Right now, it uses /tmp and I like to use /run/shm (in RAM) because in the Raspberry Pi writing to the SD card is slow. Maybe I won't have any speedup, but I'd like to try.

Thank you.

export TMPDIR=/run/shm

Thank you for the tips!

Usin TMPDIR=/run/shm now I can build on /run/shm, but I cannot run tests (or any program) there because it is mounted with noexec attribute. I know this is offtopic, but could you tell me how to mount /run/shm with exec permissions?

Thanks!

I think mounting /run/shm with exec permissions is a security hole;
why not mount a tmpfs?
mkdir /tmp/tmp; mount -o 4777,size=512M -t tmpfs tmpfs /tmp/tmp
