Maybe gcc-help is the appropriate mailing list to ask for help?
I have tried debian-ada and help-gnat, but both these lists seem to be
very low traffic lists.
Thanks!

Hi,
I'm forwarding here in hope to get some replies. No response yet from
debian-ada.
Please Cc: me since I'm not subscribed to help-gnat.
Thanks!

Subject: Almost finished porting gnat-4.6 to GNU/Hurd

Hello,
I have almost completed the cross-build and native-build of gnat-4.6.2
for GNU/Hurd. All debs does now compile and I can create packages
requiring gnat. One problem remains: Tuning the OS-interface routines.
Currently libraries and binaries build, but the binaries fail with
exception code: e.g.
./music123
raised STORAGE_ERROR : s-intman.adb:139 explicit raise
gdb music123 gives:
Program received signal SIGSEGV, Segmentation fault.
0x01050b10 in
system__task_primitives__operations__specific__initializeXnn@plt

(gdb) bt

stack_end=0x17ffd6c)
at libc-start.c:257
#8 0x0804cac9 in _start ()
so the problems seems to be in libgnarl-4.6.so.1.
Single stepping in gdb shows where the segfault occurs:
s-taprop-posix.adb:1420 Specific.Initialize (Environment_Task);
It looks like the problems is centered around
src/gcc/ada/{s-intman-posix.adb, s-taprop-posix.adb,init.c}
but from the list below there might be more files involved.
I have mainly used the kfreebsd settings and the
src/gcc/ada/gcc-interface/Makefile.in entry reads:
ifeq ($(strip $(filter-out %86 gnu%,$(arch) $(osys))),)
LIBGNAT_TARGET_PAIRS = \

EH_MECHANISM=-gcc
THREADSLIB = -lpthread
GNATLIB_SHARED = gnatlib-shared-dual
GMEM_LIB = gmemlib
LIBRARY_VERSION := $(LIB_VERSION)
endif
Unfortunately I don't know much about ADA and would really appreciate
hints on how to change the interface routines. GNU/Hurd is almost POSIX
compatible, but there are of course exceptions.
Thanks!
