Description Trev 2019-07-11 05:44:38 UTC
The included bootstrap compiler binary:
-rwxr-xr-x  1 1106  493    3386488 28 Nov  2017 ppcx64-3.0.4-freebsd

Cannot build anything - it simply core dumps with "Bad system call (core dumped)".

Truss reveals:

I installed /usr/ports/misc/compat6x - no change.
Comment 1 Trev 2019-07-21 09:00:15 UTC
The solution was to uncomment these kernel options (they are uncommented in a  GENERIC kernel) and rebuild my kernel.

##options       COMPAT_FREEBSD32        # Compatible with i386 binaries
##options       COMPAT_FREEBSD4         # Compatible with FreeBSD4
##options       COMPAT_FREEBSD5         # Compatible with FreeBSD5
##options       COMPAT_FREEBSD6         # Compatible with FreeBSD6
##options       COMPAT_FREEBSD7         # Compatible with FreeBSD7
##options       COMPAT_FREEBSD9         # Compatible with FreeBSD9
##options       COMPAT_FREEBSD10        # Compatible with FreeBSD10

It seems the FPC binaries are calling some very old FreeBSD system calls dating back some 11 years.
Comment 2 Jose Alonso Cardenas Marquez freebsd_committer freebsd_triage 2019-08-15 19:27:26 UTC
I have committed new changes to lang/fpc and editors/lazarus ports. Please, see it at:

https://svnweb.freebsd.org/ports?view=revision&revision=509004
https://svnweb.freebsd.org/ports?view=revision&revision=509005
https://svnweb.freebsd.org/ports?view=revision&revision=509007

It doesn't work with lld and maybe will not work on short time. We must be use binutils from base or from ports and change LDPATH into fpc/Makefile to ld.bfd path. Also I have regenerated fpc bootstrap (i386 and amd64) . It should be work only with COMPAT_FREEBSD11 added to kernel config on 12.X+ (COMPAT from 4 to 10 should not be necessary)

I have removed LD_UNSAFE because now we can set LDPATH to a working linker (It works with ld.bfd from base or installed from binutils port)
Comment 3 Trev 2019-08-16 02:10:09 UTC

Comment 4 Trev 2019-08-16 06:46:01 UTC
To prevent the bootstrap compiler core dumping I have determined that I need to build a kernel with:

options COMPAT_FREEBSD6         # Compatible with FreeBSD6

and

options COMPAT_FREEBSD7         # Compatible with FreeBSD7

COMPAT_FREEBSD7 was necessary because the kernel would fail to build without it once I added COMPAT_FREEBSD6.
Comment 5 Trev 2019-10-11 06:07:02 UTC
I've tracked down the source of the COMPAT6 dependency to:

/usr/local/share/fpc-3.0.4/rtl/freebsd/sysnr.inc

which includes:

syscall_nr_mmap                        = 197;

and that system call belongs to COMPAT6 (see https://github.com/freebsd/freebsd/blob/master/sys/kern/syscalls.master)

The "standard" mmap system call number is 477.

Date: Tue Dec 31 15:11:25 UTC 2019
New revision: 521624
URL: https://svnweb.freebsd.org/changeset/ports/521624

Log:
  - Change LDPATH to FPC_LDPATH into lang/fpc/Makefile. It can be changed from
    /etc/make.conf
  - Add FPC_LDPATH to freepascal compiler. By default it is defined to
    %%LOCALBASE%%/bin/ld.bfd but it can be changed setting FPC_LDPATH environment
    variable
  - Remove compatX dependencies from bootstrap and compiler. It could fix problems
    when GENERIC kernel is not used [1]
  - Rebuild bootstrap (ppcx64 and ppc386) with new changes
  - Bump PORTREVISION

Hi Trev

Could you test my latest fpc commit? It should works now. Thanks!
Comment 8 Trev 2020-01-04 22:12:12 UTC
(In reply to Jose Alonso Cardenas Marquez from comment #7)
Sure, will test in the next couple of days (need to compile a new kernel).

Comment 11 Jose Alonso Cardenas Marquez freebsd_committer freebsd_triage 2020-02-24 21:50:36 UTC
Hi, I put a new version of fpc ports at the following url:

https://people.freebsd.org/~acm/ports/freepascal/

1) Copy ppc*-freebsd.tar.gz files at /usr/ports/distfiles/freepascal
2) Uncompress fpc.tar.gz and copy fpc directory to /usr/ports/lang/
3) cd /usr/ports/lang/fpc && make install clean clean-depends

It should works fine on FreeBSD 11.x and FreeBSD 12.x (COMPAT11.X should be enable in KERNEL). COMPAT < 11 should not neccesary

Please test it and tell me if it works for you
Comment 12 Trev 2020-03-04 02:23:37 UTC
Success! Yes, this version compiles perfectly and my tests using it were all successful. Thank you very much for your efforts.

Just a note on the blurb displayed after installing: 

"1) Add lib paths to /usr/local/etc/fpc.cfg

   # searchpath for libraries
   -Fl/usr/local/lib
 
    This is necessary for correct linking of libraries."

When I checked fpc.cfg, this path was already there as follows:

"# searchpath for libraries
#-Fl/usr/local/lib/fpc/$fpcversion/lib
#-Fl/lib;/usr/lib
-Fl/usr/local/lib;/usr/local/lib/qt4;/usr/local/lib/qt5/fpc/$fpcversion/lib/$FPCTARGET"

So maybe that first note is not needed.

Additionally, while trying to retrieve the source some of the mirrors no longer exist and others failed to connect as follows:
