External build directory with default generated makefiles about ace_tao HOT 3 OPEN

Building for multiple targets is possible. This can be achieved without an external build directory.

There are two existing tools to consider:

• Define the makefile variable ARCH to redirect build outputs to that subdirectory
• $MPC_ROOT/clone_build_tree.pl creates "virtual" source trees using symlinks, and these can be used like external build directories

Let us know if those don't work for your use case.

I'd never though of a symlink tree, but I imagine one would take up some space given the sheer number of files in the ACE/TAO distro, right?

Will ARCH also place final static/dynamic library products in separate subdirectories?

On my system it takes about 45 MB for symlinks to to the full ACE_TAO source tree (which itself uses 162 MB). Deleting unneeded subdirectories reduces it to 13 MB of symlinks for 90 MB of source. Storage space is pretty cheap these days so this seems reasonable to me.

For this test I removed these ACE subdirectories:
rm -rf ASNMP apps/{drwho,Gateway,JAWS*,mkcsregdb,soreduce} contrib debian examples netsvcs performance-tests rpmbuild tests websvcs ACEXML/tests ACEXML/examples Kokyu/tests protocols/tests protocols/examples

And these from TAO:
rm -rf DevGuideExamples examples interop-tests performance-tests tests orbsvcs/{tests,examples,performance-tests,DevGuideExamples}

The TAO_ACE.mwc workspace, which is what we recommend using, should still build fine with these directories left out. The list of directories to remove could probably be refined if space is really at a premium, this just a list I've used before for similar activities.

Yes.
