I'm trying to build a fpmake project for the RTL.  One problem I'm struggling with is how to add an assembler file to the package and assign a custom command to be executed instead of calling the compiler.  I've tried the following, which does call "as" but then it follows with an error because the compiler gets called with the assembler file which then generates an error:

   T := TTarget(P.Targets.Add);
   T.Name := 'linux/'+CPUToString(Defaults.CPU)+'/prt0.as';
   T.CPUs := [x86_64];
   T.OSes := [linux];
   T.Commands.AddCommand('as', '--64 -o ' + 'prt0.o ' +
'linux/'+CPUToString(Defaults.CPU)+'/prt0.as', 'prt0.o', 'prt0.as');

Looking at the various methods of TTarget (addUnit, addFPDoc, addProgram, addImplicitUnit) seems to suggest that functionality for adding a generic file and calling an external custom command is lacking.

Any ideas or suggestions on how to get this case working?

Are you aware that the RTL already has a fpmake project? It might not be entirely up to date, but it exists.

I somehow did not notice the existing fpmake before, it seems impossible to miss now! Anyway, seems like some more work is still required to make the existing fpmake usable.  It also doesn't have support for assembling assembler source files, so my original question remains.

Did you look at the rtl/linux/fpmake.inc file? It adds the loaders there. Though I have not tested it and don't know if it works.

Thanks for the hint Sven, my mistake seems to be creating a new target for the loaders.
