Hi,
I would like to run radare on OpenBSD. I see that it is not yet
ready, needs a
systcl interface defined (simple but tedious). I guess there may be
other bits
missing too.
Cool, portability to BSD was one of our priorities for 0.8.
why do you need from sysctl? hope it's not a joke #aprilfools? :P
Here are some patches to actually get it building anyway:
https://github.com/vext01/ports-wip/tree/master/devel/radare/patches
Cheers
Finally I got some spare time to review the patches... :) what a
stressful day!
** patch-binr_radare2_Makefile:
There's a TH_LIBS var in libr/config.mk that should do this job. in
fact i plan to
remove all threading stuff in r2.. it's not used anywhere now (I was
using it
in r2 -t to load code analysis in background) but the optimizations we
are doing
for 0.8 will make this unnecessary. Code analysis is fast enought to
not complicate
the code with more threading stuff.
** patch-libr_core_core_c
signal.h is not a portable include. I will commit this but inside a
#if __UNIX__ block. Thanks.
** patch-libr_debug_p_debug_native_c
If you check r1 source code you'll see that the implementation of the
debugger in BSD is
based on redefines of the linux ptrace enums (PTRACE_*), this is the
same you are
doing here. This is ok, but as long as you are doing the same changes
in io_ptrace patch
I would suggest you to do this change in a .h shared by both
libraries. This way the
portability to netbsd and freebsd (and gnu/kfreebsd?) will be simpler.
Can you do this change?
** patch-libr_io_p_io_debug_c
This is ok, as long as this will be required for other BSD systems to
make fork+ptraceme work.
I'm going to commit this change, but using __BSD__ instead of the
specific __OpenBSD__
** patch-libr_io_p_io_ptrace_c
As mentioned earlier in this mail I think this change must be done
once libr/include/r_debug_internal.h ?
so you dont have of ifdef every call to ptrace(). Can you do this change?
I'm gonna review the other PTRACE_ redefinition patch...so .. maybe i
can do I better solution and
you can try it for me (i have no BSD in any box of mine atm)
