[Vm-dev] Re: About sqSCCVersion.h

[Javier Pimás]

just to document... the script to execute is in
/path/to/vmsource/codegen-scripts/extract-commit-info.sh, and as its comment
says, should be run from build dir, like this:

build$ ../codegen-scripts/extract-commit-info.sh

after that, everything should work.

cheers,
Javier.
