[fpc-devel] adding x86_64-netbsd
Hi List,
I've been fiddling around adding netbsd x86_64 to fpc 2.2.4, I've got it
to the point that I can compile both the rtl and the compiler but I'm
having difficulties creating the prt0.as file(s).
I can't link anything due to missing symbols;
[...]
Assembling pp
Linking ./pp
/home/axel/Sources/FPC/fpcbuild-2.2.4-netbsd_x86_64/fpcsrc/rtl/units/x86_64-netbsd/prt0.o:
In function `___start':
crt0.c:(.text+0xc5): undefined reference to `_fini'
crt0.c:(.text+0xd0): undefined reference to `_(float, char __restrict *,
wchar_t)'
crt0.c:(.text+0xe3): undefined reference to `main'
[..snip!..]
The file I created is a somewhat modified .s output from crt0.c from
netbsd. Can someone help me a bit with this?
I've included a patch with the things I changed (but there's some build
leftovers in it too, sorry)
I used to program a lot in pascal for school about 16yrs ago, it would
be fun to start playing with it again :)
Kind regards,
Axel Scheepers

Axel, It was difficult to create the port to NetBSD? In my company we have several OpenBSD installs and it would be nice if we could run FPC apps on them. Leonardo M.

That's great!, I'll try to compile it this week. Leonardo M.

Re: [fpc-devel] adding x86_64-netbsd
Oh, I also had to build a fpcmake beforehand (see
fpcsrc/utils/fpcm/fpcmmain.pp) and did a
find /path/to/toplevel/source/dir -name Makefile.fpc
-exec /path/to/new/fpcmake -Tall {} \;
I also had to cross build a binutils and put that in my $PATH.
I have some spare time coming, I should take a better look at the
freebsd prt0.as and see if I can work from there to see if my mess can
produce a netbsd-/amd64 binary so I can try to build a native fpc for
it.
Kind regards,
Axel Scheepers
