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.

Hi Leonardo,

It's my first try at it, I don't know if I missed something except the obvious prt0.as problems I'm having. From what I saw most of the *bsd is already defined and I even saw an openbsd i386/m68k target, take a look at fpcsrc/compiler/systems.pas,
fpcsrc/compiler/systems/i_bsd.pas
fpcsrc/compiler/systems/t_bsd.pas and
fpcsrc/rtl/openbsd/

Kind regards,

Axel Scheepers

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

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,
