[Pkg-pascal-devel] Bug#978040: Warning: (9034) "crtbeginS.o" not found (on non-intel architectures)

[Matija Nalis]

Package: fpc
Version: 3.2.0+dfsg-8
Severity: normal
X-Debbugs-Cc: mnalis-debianbug at voyager.hr

Dear Maintainer,

   * What led up to the situation?

trying to compile my source throws warnings (which subsequently causes failure to build due to "-Sewnh". 
I can of course remove that option and continue build even in presence of warnings, but would like to fix 
the  problem at the source, as it is simple fix):

fpc -Mtp -g -gl -gv -fPIC -C3 -Ci -Co -CO  -O1 -gw -godwarfsets  -gt -vewnhiq   -Sa -Sy  -vm4049 -Sewnh -k-lSDL_mixer -k-lSDL -k-lm -k'-z relro' -k'-z now' -k-pie is.pas
Hint: (11030) Start of reading config file /etc/fpc.cfg
Hint: (11031) End of reading config file /etc/fpc.cfg

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

it seems that required /usr/lib/gcc/XXXXX/YYYY library path is not included on fpc.cfg on ARM architectures
(https://buildd.debian.org/status/package.php?p=ironseed shows that warnings at least for arm64, armel, armhf)

It is mentioned in FAQ at https://wiki.lazarus.freepascal.org/Lazarus_Faq#I_receive_a_warning_during_the_linking_that_states:_Warning:_.22crtbeginS.o.22_.28or_.22crtendS.o.22.29_not_found
and manually adding "-Fl/usr/lib/gcc/arm-linux-gnueabihf/10" to /etc/fpc-3.2.0.cfg fixes the problem.
Similar library path is already present for amd64/i386 inside ifdef marked with "# path to the gcclib".
It should be simple to add it to non-intel architectures too.

   * What was the outcome of this action?

The two warnings show above appear (and so build fails due to '-Sewnh')

   * What outcome did you expect instead?

No warnings, and sucessful build on ARM.
