gnport

A port of the Google Generate Ninja (gn) meta-build system to z/OS Open Tools project

Developer Notes

In case of an error, use this workflow to ensure the file system is in pristine state.

$ zopen remove -p zoslib
$ zopen-clean --all -c -d -u -v
$ zopen clean -d

Afterwards, examine the file system for no stale binaries.

$ cd ${HOME}/zopen
$ find . -name "libzoslib*"

Note, a copy of zoslib will show up as $HOME/zopen/usr/local/bin/CMakeFiles/libzoslib.dir but that is ok. No need to remove in order to build gnport.

Actual build of gnport

Once the the filesystem is pristine, do the actual build.

$ cd ${HOME}/zopen/dev/gnport
$ rm -rf gn
$ zopen build

A good build will have results in ~/zopen as shown:

(NOTE: the timestamps will vary over time.)

$ ~/zopen
$ find . -name "libzoslib*"
