[SOLVED] How to install an AVR-cross-compiler for multiple AVR-subarches?

[Hartmut]

Some time ago I successfully installed FPC 3.2.2 with Lazarus 2.2.4 with AVR-cross-compiler for AVR-subarch 'avr5' by fpcupdeluxe version 2.2.0n on Linux Ubuntu 18.04 64-bit.

Now I need AVR-cross-compiler for AVR-subarch 'avr25'.

My question is: what will happen, if I use fpcupdeluxe again to install AVR-cross-compiler for AVR-subarch 'avr25'?
a) will I have subarches 'avr5' and 'avr25' both working?
b) or will I loose subarch 'avr5' to have 'avr25' working?
c) or will I damage my installation and have none of both?

Does somebody know this? Thanks in advance.

As fpcupdeluxe makes isolated installs, you can just use (the latest version of) fpcupdeluxe to make a new install in a new directory and give it a try !

I would suggest you run your cross-compiler in a terminal window and specify -ic. Then you can see if that sub-architecture might already be supported. Note that you may still need the correct toolchain but I guess you know that.

Thank you DonAlfredo for your quick reply. But I don't want to make one additional Lazarus installation, if not really needed. AFAIK you are the father of fpcupdeluxe.
Please, what will happen, if I use fpcupdeluxe again to install AVR-cross-compiler for AVR-subarch 'avr25' over my existing 'avr5' installation?

a) will I have subarches 'avr5' and 'avr25' both working?
b) or will I loose subarch 'avr5' to have 'avr25' working?
c) or will I damage my installation and have none of both?

[Thaddy]

Did you run my suggestion? Obviously not!

Hello Thaddy,

yes, I did run your suggestion:

hg6@i3300:/opt/lazarus_224/fpc/bin/x86_64-linux$ ./fpc -ic
ATHLON64
COREI
COREAVX
COREAVX2

But how does this answer my question:

You did not run the cross-compiler. The cross compiler should give you the AVR versions that are supported.
If I run my cross compilers for e.g. ARM I get a long list of supported ARM processors.

[DonAlfredo]

In theory, having two subarchs should work.
Fpcupdeluxe employs some trickery to do so.
E.g. this is by fpc.cfg for avr5 and avr25

Code: Pascal  [Select][+][-]

1. # begin fpcup do not remove avr-embedded
2. # Inserted by fpcup 17/03/2023 10:13:17
3. # Cross compile settings dependent on both target OS and target CPU
4. #IFDEF FPC_CROSSCOMPILING
5. #IFDEF EMBEDDED
6. #IFDEF CPUAVR
7. #IFDEF CPUAVR5
8. #ENDIF CPUAVR5
9. #IFDEF CPUAVR25
10. #ENDIF CPUAVR25
11. -FDC:\fpcupsystems\avr\cross\bin\avr-embedded
12. -XPavr-embedded-
13. -FlC:\fpcupsystems\avr\cross\lib\avr-embedded\$FPCSUBARCH
14. -FuC:\fpcupsystems\avr\fpc\units\avr-embedded\$FPCSUBARCH\rtl
15. -FuC:\fpcupsystems\avr\fpc\units\avr-embedded\$FPCSUBARCH\packages
16. #ENDIF CPUAVR
17. #ENDIF EMBEDDED
18. #ENDIF FPC_CROSSCOMPILING
19. # end fpcup do not remove

The unit-files for avr5 and avr25 are installed in a separate subdir of avr-embedded.
A fake system.ppu is added to satisfy Lazarus in the base directory.

You did not run the cross-compiler.

Ok, did not know that. Please how do I start the cross-compiler?


Thank you very much DonAlfredo for answering my question. I will try to install subarch 'avr25' over my existing 'avr5' installation.

[DonAlfredo]

See screenshot !
Select the avr25 subarch and you should be good to go.
Remember, I use the latest fpcupdeluxe (pre-release).

You did not run the cross-compiler. The cross compiler should give you the AVR versions that are supported.
If I run my cross compilers for e.g. ARM I get a long list of supported ARM processors.

Yes, this will confirm which controllers and subarchitectures the compiler supports.  It does not however guarantee that the RTL and package units for a particular subarch is actually installed.  fpcupdeluxe only install the selected subarch.  Thus, as Don explained, one has to repeat the installation for all the subarches the user needs.

I would suggest you run your cross-compiler in a terminal window and specify -ic. Then you can see if that sub-architecture might already be supported. Note that you may still need the correct toolchain but I guess you know that.

A compiler binary supports all the subarchitectures for a given platform (if they are handled as subarchitectures, so ARM vs. ARMHF or ARMEL vs ARMEB does not count), however the RTL needs to be compiled for that subarchitecture and that can't be reported by the compiler.

You did not run the cross-compiler.

Ok, did not know that. Please how do I start the cross-compiler?

Assuming that the fpc binary can locate the AVR cross compiler you can simply use fpc -P<platform> (e.g. fpc -Pavr) plus whatever additional parameters you need (e.g. -i) to invoke the specific cross compiler with those parameters.

[Hartmut]

Thanks to ccrause and PascalDragon for clarification.

hg6@i3300:/opt/lazarus_224/fpc/bin/x86_64-linux$ ./fpc -Pavr -ic

shows

AVR1
AVR2
AVR25
AVR3
AVR31
AVR35
AVR4
AVR5
AVR51
AVR6

although only AVR5 is installed, as you said.

[Hartmut]

Now I installed with fpcupdeluxe Version 2.2.0qp (Pre-release) AVR-subarch 'avr25' over subarch 'avr5' and it worked perfectly. Now I can use both subarches parallel. Many thanks to DonAlfredo and all others who have helped me.

With me everything goes parallel, dan Don Alfredo.
