[fpc-pascal]FPC & c-library

[Peter Beisel]

thank you,

but I couldn't find PMODE/W or PMWBIND anywhere.

1. DOS4GW & EXE (by WatCom)  <----> CWSDPMI & EXE (by FPC)

Without such a tool it seems impossible to run a DOS4GW executable
generated by a WatCom Compiler under CWSDPMI.

On the other hand an EXE-file generated by FPC can't be executed under
DOS4GW. DOS4GW doesn't recognise the EXE, because of the CWSDPMI-Header
added by the stub under FPC. Now I tried to remove this header. The
FPC docs explain the usage of the tool EXE2COFF. But this tool is nowhere.
I found EXE2COFF in the DJGPP tools and I tried this:
   EXE2COFF myFPprog.EXE    (myFPProg.EXE = generated by FPC)
Result:
   myFPprog; Permission denied (EACCES)

Are there different EXE2COFFs?


2.
I found no way to link a WatCom generated *.LIB or *.OBJ to a FPC
programm. The FP linker doesn't accept them.

Regards, Peter
