[SOLVED] Building units fails after updating fpmake.pp (for sinclair QL)

[NormanDunbar]

Good afternoon.

Here's a timeline showing the problem I'm having, TL;DR is building the units, RTL or cross compiler fails after amending the fpmake.pp file for the units.

1. #--------------------------------------------------------------
2. # Start with a clean slate.
3. rm -Rf FPC_Source/
4. git clone git@gitlab.com:freepascal.org/fpc/source.git --depth 1 FPC_Source
5. cd FPC_Source/
6. #--------------------------------------------------------------
7. #--------------------------------------------------------------
8. # Build cross compiler.
9. make clean OS_TARGET=sinclairql CPU_TARGET=m68k
10. make crossall OS_TARGET=sinclairql CPU_TARGET=m68k
11. #-------------------------------------------------------------
12. #--------------------------------------------------------------
13. # Install the cross comiler.
14. make crossinstall OS_TARGET=sinclairql CPU_TARGET=m68k INSTALL_PREFIX=/home/norman/bin
15. #--------------------------------------------------------------
16. #--------------------------------------------------------------
17. # Symlink it to "fpc-ql".
18. ln -s lib/fpc/n.n.n/ppcross68k fpc-ql
19. #--------------------------------------------------------------
20. #--------------------------------------------------------------
21. # Build RTL with the cross compiler.
22. make rtl_cleanall OS_TARGET=sinclairql CPU_TARGET=m68k
23. make rtl_all RELEASE=1 FPC=fpc-ql OS_TARGET=sinclairql CPU_TARGET=m68k
24. #--------------------------------------------------------------
25. #--------------------------------------------------------------
26. # Build the QL units with the cross compiler.
27. make packages_clean OS_TARGET=sinclairql CPU_TARGET=m68k
28. make packages RELEASE=1 FPC=fpc-ql OS_TARGET=sinclairql CPU_TARGET=m68k
29. #--------------------------------------------------------------
30. #--------------------------------------------------------------
31. # Do my work here. I've created a new "screen" unit for the QL.
32. # But even if I do nothing, the problem still occurs.
33. #--------------------------------------------------------------
34. #--------------------------------------------------------------
35. # Build the QL units with the cross compiler - BEFORE updating fpmake.pp.
36. make packages_clean OS_TARGET=sinclairql CPU_TARGET=m68k
37. make packages RELEASE=1 FPC=fpc-ql OS_TARGET=sinclairql CPU_TARGET=m68k
38. #--------------------------------------------------------------
39. #--------------------------------------------------------------
40. # Amend packages/qlunits/fpmake.pp
41. # Here I'm simply touching it, I could amend it to add my unit name to the build.
42. ls -l packages/qlunits/fpmake.pp
43. -rw-rw-r-- 1 norman norman 1270 Apr 18 13:45 packages/qlunits/fpmake.pp
44.  
45. touch packages/qlunits/fpmake.pp
46.  
47. ls -l packages/qlunits/fpmake.pp
48. -rw-rw-r-- 1 norman norman 1270 Apr 18 13:53 packages/qlunits/fpmake.pp
49. #--------------------------------------------------------------
50. #--------------------------------------------------------------
51. # Build the QL units with the cross compiler - AFTER updating fpmake.pp.
52. make packages_clean OS_TARGET=sinclairql CPU_TARGET=m68k
53. make packages RELEASE=1 FPC=fpc-ql OS_TARGET=sinclairql CPU_TARGET=m68k
54. #--------------------------------------------------------------

And then, this happens...

20.  

Now, I haven't even changed the content of fpmake.pp, I simply "touched" it, but the same error occurs if I add my new unit name to the file, or if I open and save it unchanged etc. As soon as that file changes, everything crashes. Now, I can no longer build the units, the rtl or the cross compiler.

Up until I change that file in any way, I can build and rebuild the cross compiler, the RTL and the units many times over.

I've run another test, in case it was somehow my new unit, but I didn't add in the new unit file, everything works fine up until fpmake.pp gets touched/changed then nothing will compile.

Once again, I'm grateful for any assistance that can be offered. When I last built units, around 2023, I never encountered this problem.


Cheers,
Norm.

I'm not sure if it matters, but my cross compiler's fpc.cfg is located in ${INSTALL_DIR}/lib/fpc/etc/fpc.cfg, and the content is as follows:

#IFDEF CPUM68K
-Tsinclairql
-Fu/home/norman/bin/lib/fpc/$fpcversion/units/$fpccpu-$fpcos
-Fu/home/norman/bin/lib/fpc/$fpcversion/units/$fpccpu-$fpcos/*
#IFDEF SINCLAIRQL
-FD/usr/local/bin
-XPm68k-sinclairql-
#ENDIF
#ENDIF

$fpcversion is 3.3.1.
$fpccpu is m68k
$fpcos is sinclairql.

There are unit files (*.o and *.ppu)  in both of those locations. One of which is named system.o and system.ppu.

For my host compiler, the config file is /etc/fpc.cfg and it has the following "-Fu" options:


-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/$fpcsubarch-$fpcmemorymodel
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/$fpcsubarch-$fpcmemorymodel/*
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/$fpcsubarch-$fpcmemorymodel/rtl
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/*
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/rtl
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/httpd13/
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/httpd20
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/httpd22
-Fu~/.fppkg/lib/fpc/$fpcversion/units/$FPCTARGET/*

The only ones that exist are these two:


-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/*


And, there are a lot of units in there.


Cheers,
Norm.

Problem solved! I installed Lazarus and it broke my installation of FPC.

FPC was originally installed into /usr/local/bin but Lazarus installed into /usr/local. This messed up my cross compiler's unit paths. 


Cheers,
Norm.

You can avoid that in the future by specifying PREFIX=/usr I believe.
