Fatal Error: Cannot open module file 'lbfgsb_entry.mod0' for writing at (1): Permission denied

[idavydov]

When using this module from another package, the following error occurs:

$ CGO_LDFLAGS="-framework Accelerate" CC=gcc-11 go install  bitbucket.org/Davydov/godon/godon@latest
# github.com/idavydov/go-lbfgsb
lbfgsb__entry.f90:51:23:

   51 | end module lbfgsb_entry
      |                       1
Fatal Error: Cannot open module file 'lbfgsb_entry.mod0' for writing at (1): Permission denied
compilation terminated.

This is related to golang/go#48349.

The current work-around is to use the -J and -I flags:

CGO_FFLAGS="-J $TMPDIR -I $TMPDIR" CGO_LDFLAGS="-framework Accelerate" CC=gcc-11 go install -x bitbucket.org/Davydov/godon/godon@latest

Please note that "-framework Accelerate" is specific to Mac OS X.
