what to do for achieving

make all OS_TARGET=ps1 CPU_TARGET=mips


I'm not clear what make files have to be changed.
He tells me:
Makefile:252: *** The Makefile doesn't support target mips-ps1, please
run fpcmake first.  Stop.

fpcmake -Tmips-ps1
tells me:
Error: No targets set


pls Step by Step explain, thx

make should be called from fpcmake, you should not try to edit or
write your own makefile.
fpcmake is well documented.
https://www.freepascal.org/docs-html/prog/progap5.html

Really, pay attention to that and make sure you are familiar with that
if you want to write your own compiler.

Note that fpcmake may need modifications for architectures and maybe
even OSes too. IIRC there is a loop in there that enumerates all of
them

Key-Real · 2024-07-19 07:39

ok, i read the entire doc and still have no clue.

pls some hints

@Key-real,
There is your answer: make sure your compiler is in the enumeration.

----------------------------------------------------------------------
Key-Real · 2024-07-19 07:45

what enumeration?
which file?

----------------------------------------------------------------------
Key-Real · 2024-07-19 07:54

there are thousands of MakeFile.fpc's
in each folder one.

where is that magic enumeration?

this is my makefile.fpc in ./rtl/ps1

There is only one make file for the compiler. Add your compiler to the
list of targets.

----------------------------------------------------------------------
Key-Real · 2024-07-19 08:15

where? which FILE?

----------------------------------------------------------------------
Key-Real · 2024-07-19 08:22

EY

just tell me:
1)
take ./compier/makefile.fpc (as example)
2)
add ps1 (as example) to mysection(as example)

----------------------------------------------------------------------
Thaddy · 2024-07-19 08:26

yes, that should work.

sorry, but I'm getting mad

tell me:

EDIT FILE.CFG,
PUT PS1 SectionX

----------------------------------------------------------------------

It's not a single place. It's likely many places. Look at how support
for the "embedded" or "freertos" target is done for example. Search
for all strings "freertos" that aren't from autogenerated files and
you'll get an idea about places where you need to add your custom
target

A good place to start is to add ps1 in utils/fpcm/fpcmmain.pp

----------------------------------------------------------------------
Key-Real · 2024-07-19 12:04

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

----------------------------------------------------------------------
nickysn · 2024-07-19 12:14

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 · 2024-07-19 12:20

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

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

----------------------------------------------------------------------
Key-Real · 2024-07-19 12:33

he still tryes to compile fpcmake

----------------------------------------------------------------------
TRon · 2024-07-19 12:33

@nickysn:
+1

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.

----------------------------------------------------------------------
Key-Real · 2024-07-19 12:35

but I'm building a crosscompiler.

how this should affect the host?

----------------------------------------------------------------------
nickysn · 2024-07-19 12:41

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 ?

Quotehow 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 · 2024-07-19 14:16

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?

----------------------------------------------------------------------
Key-Real · 2024-07-19 14:46

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.....
