Thank you Tomas, I didn't specify the correct options to data2inc.
I managed to regenerate a makefile which reflected the changes in fpcmake.ini!

...the fpmake issue at the moment, but it's a FPC program and it should be
possible to debug it the usual way to find out why it doesn't generate the
.inc file as expected.

Hope this helps

Did you try removing the fpcmake.inc before running make?

If you look into fpmake.pp in the same directory, you'll find out that the
proper command line for calling data2inc should be:

data2inc -b -s fpcmake.ini fpcmake.inc fpcmakeini

(add paths as necessary, e.g. the path to data2inc if not on PATH)

I guess that this is again due to wrong parameters, but that's really just
a guess. Anyway, running 'data2inc data2inc.exm demo.inc' as suggested
within data2inc.exm works for me (using data2inc from the 3.0.4
installation, but that shouldn't make a difference).

Indeed - I'm pretty sure that it should work when using the right parameters.

Invoking of data2inc from fpmake may not be as mature though (as suggested
by your experience with running make in the fpcm directory). I don't have
time for debugging

The .inc file is not regenerated when running make in the fpcm directory.
At first the data2inc utility couldn't be found, fixed that by specifying
DATA2INC=path/to/data2inc. This still didn't regenerate the .inc file.  Tried 
to generate only the .inc file by calling data2inc manually passing unmodified
fpcmake.ini as input - this resulted in a parsing error:

~/fpc/3.1.1/utils/fpcm $ ../bin/x86_64-linux/data2inc fpcmake.ini fpcmake.inc
processing file : fpcmake.ini
Some error with a \xxx constant or a stale (unescaped) backslash
Error in line : 35 Somewhere near :'OVERR'

Data2inc also gives an error when reading data2inc.exm, which seems strange.
Same error when testing data2inc of 3.0.4 (compiled from source). I've already 
deleted, restored and rebuild the utils directory of trunk but get the same 
error.

This is really strange because data2inc seems like a very mature tool.

The .ini file should be translated to .inc using the data2inc utility
(included with FPC as well) and then incorporated into the binary. This
should happen automatically, but let's make sure it was the case for you
as well.

Apart from that, I would make sure that the right (newly compiled) fpcmake
binary was really called rather than some previously existing one - I
believe that building puts the new one in a subdirectory called 'bin'
rather than the main fpcm directory, that's why I asked whether you copied
it there if called using the ./fpcmake path.

My update procedure is basically what you describe: I manually added the
changes from r30766 fpcmake.ini to trunk, then call make inside the fpcm
directory, then execute the newly compiled fpcmake with the Makefile.fpc
file in the fpcm directory as test.

Tonight I will check if fpcmake.inc got updated.  Thanks for this hint, I

I assume that you updated fpcmake.ini in /fpcsrc/utils/fpcm/ (or without
/fpcsrc if using a checkout of the fpc repository rather than fpcbuild)
and rebuilt either all utils, or just fpcmake, right? Could you please

I'm trying to move Florian's changes in the target-subdir branch to trunk. I've 
updated
fpcmake.ini, but when I compile fpcmake and execute ./fpcmake -Tall -w 
Makefile.fpc the
regenerated MakeFile doesn't have any of the modifications in fpcmake.ini.

Any hints on how to compile and use fpcmake so that changes in the ini file 
ends up in the
generated MakeFile?

Re: [fpc-pascal] Is this the correct way to configure fpc for multiple arm-embedded subarchs?

[Michael Ring]

I am doing something similar to what you are doing, see below

I also needed to create a softlink so that fpc can call ppcrossarm, it 
expects to call ppcarm


By using 'INSTALL_UNITDIR' there is no need to copy files at the end.

You will need to do a little tweak in fpc.cfg, after this it is 
transparent to handle the different subarchs, at least for arm and 
mipsel ;-)


Now I can use fpc to select matching arch/subarch and Lazarus works just 
fine.

There is a similar problem with the AVR target having several
subarchitectures.  One option I think is to have a subarch defined by
the compiler, then it would be easy to lay out the compiled unit
structure in fpc.cfg according to subarch.  I've made an attempt at
adding a subarch define to my local compiler source for AVR, but
haven't developed the idea further.  I'm not a compiler dev so there
may be better options.

Subarch directories are imo the best solution, I have a half-backen patch for 
this, not yet
finished
though.

I've made a script file (attached) that iterates through the different 
subarchitectures
available for the AVR compiler, calls make and then moves the compiled units to 
a subdirectory.
I think the logic of this script should be moved to the existing rtl makefile 
so that all
subarchitectures for a target gets generated and sorted in one go.  Of course 
then the default
fpc.cfg ideally needs to be updated to reflect the subarch folder structure for 
ARM and AVR.

I'm putting this out there hoping that someone familiar with the topic and 
makefile syntax can

I've missed a critical bit om information until now - there is a config file 
macro replacement
option called $FPCSUBARCH available since r29316.  At the moment I've modified 
my .fpc.cfg to
use the following include to locate RTL units:

#IFDEF EMBEDDED
-Fu~/fpc/$fpcversion/rtl/units/$fpctarget/$FPCSUBARCH/
#ELSE
-Fu~/fpc/$fpcversion/rtl/units/$fpctarget/
#ENDIF

So far I've compiled the AVR RTL for different subarch types, then copied the 
units into their
respective subdirectories.  Once this is done switching between different 
controllers
irrespective of subarch type works.

The additional work required is in my opinion:
* Change makefile to automatically compile all available controllers by subarch 
type and specify
output directory as rtl/units/$FPCTARGET/$FPCSUBARCH/ or as appropriate for 
directory
configuration.
* Update fpc.cfg template to reflect change in default rtl directory structure.

Not sure if this approach will work for all embedded targets though.
