[Flightgear-devel] fg-from-scratch further development

[Patrick C. <pat...@gm...>]

I'm about to start working on a debug build, based on fg-from-scratch.cmd

As currently written, the script is fully capable of producing a release
build for flightgear and terragear.  Currently It leverages vcpkg, and
cmake to  produce the release executables.  As part of its build it
produces windows versions of all of the open-source libraries that underlie
openscenegraph, simgear, flightgear and terragear.  Starting with Cmake, it
produces  a visual studio project that can be used to rebuild the release
version, but currently fails to produce a working debug version.

Before starting, in order to fully understand the existing fg-from-scratch,
I'm doing a bit of reading on vcpkg, cmake and visual studio and examining
the existing directory structure and files.

As for changes, there's no need to wait. I'll be watching for merge
requests to the fg-meta/fg-from-scratch folder.  Don't hold back...

I'll be doing a deep dive until I feel ready to propose specific changes to
the existing script.  If you want to work with me on this you can contact
me through a reply to this thread.  I have a phone, a gmail account (google
hangouts) and an IRC client for real time communication.  I'll be posting
notes to

In the meantime, anyone with a sense of what needs doing is welcome to
respond to this thread with suggestions or direction.

*ninja:*
*Task*: Find out if ninja is currently used  in fg-from-scratch.cmd if it
is include it in research.  If not, discuss advantages/disadvantages with
the wider flightgear development community.

*Per target build and install directories:*
*Task:* A technique I've observed in use is to provide separate build and
install directories for each target build: release, rel-with-debug, debug.
Investigate vcpkg-git, scratch-build and scratch-install to determine where
this technique is and is not used.
