how to setup rtl makefile?

[Key-Real]

I done all the nesessery changes in /utils/fpcm

now if I do
make all CPU_TARGET=mipsel OS_TARGET=ps1

the crosscompiler is compiled but further building tells me:
/home/key-real/vip-code/source/compiler/ppc fpcmake.pp -n -Fu/home/key-real/vip-code/source/rtl -FU
Fatal: Can't find unit system used by fpcmake
Fatal: Compilation aborted

What do you mean by "further building"? What are you trying to achieve? Are you trying to compile fpcmake? Then, do a 'make clean && make all' in the root fpc directory. If you're trying to do something else, please explain what and how.

[Key-Real]

yes I done
'make clean && make all'
he makes me a build for linux
now i do
'make all CPU_TARGET=mipsel OS_TARGET=ps1'
at some stage of building he tells me

Code: Pascal  [Select][+][-]

1. /home/key-real/vip-code/source/compiler/ppc fpcmake.pp  -Fu/home/key-real/vip-code/source/rtl -FU

which indicates that the system unit is not pre-compiled.

What happens if you try the following:

1) make clean && make all
2) copy the generated fpcmake somewhere outside the fpc git repository
3) make all CPU_TARGET=mipsel OS_TARGET=ps1 FPCMAKENEW=path/to/your/new/fpcmake

he still tryes to compile fpcmake

Afaik you can't do this in one go. In order to compile the rtl you first need to update the makefile(s) but if the target isn't present yet the make process complains.

but I'm building a crosscompiler.

how this should affect the host?

[nickysn]

It could help if you were attaching the complete build log, as well as your commands. It would be easier to answer why it's trying to build fpcmake, if we know *when* (at what stage) does it try to build it. Is it after building the compiler, is it after building the rtl, is it before building packages, is it after? Always paste more information, not less.

Yes, and how do you think the cross-compiler is build ?

how this should affect the host?

Making the cross-compiler is not affecting the host. The host compiler needs to be aware of the (cross)-target otherwise it can't build the cross-compiler.

At least I am not aware of any shortcut there e.g. it is a chicken and egg problem.

[nickysn]

Key-Real, the log you've attached shows a different error. What is it that you're trying to do? What was the make command, that generated this log?

I gonna clone the fresh compiler and make my step by step port, than we can look at it again....
this would take a while.....
