Here is the batch build package - it has been tested on my largest program, the one mentioned previously.
It successfully builds from the IDE, or from a command window, the batch created final exe file
matched exactly the build by the IDE.
Change a few lines in make_all.bat, create baselink.lst (only 7 lines) and ready to build.
Limitations: All source files must be in the same directory for make_objs.bat. If multiple
directories are used clone make_objs.bat to make_objs1.bat 2.bat etc., and change
the source location in each. Then call each from the make_all.bat
Biggest thing is you must make the baselink.lst for the project manually
A general guide is in the 7z, and directions are also in each file as to what to change.
Hopefully useful, but if not its OK....
