Subject: [Boost-users] Boost 1.36 portability issues on FreeBSD 6.x?

I have a FreeBSD 6.1 amd64 box and I'm running into various issues
building boost on my platform. In no particular order:

- libboost_prg_exec_monitor checks for a lot of optional signal codes
(execution_monitor.ipp file) that FreeBSD 6.1 does not support AND
FreeBSD 7 supports somewhat. I'm talking about the XSI codes for
SIGCHLD, SIGILL, etc. in my /usr/include/sys/signal.h (amd64 tree but
is also a problem on my x86 branch):

 #define ILL_ILLOPC 1 /* [XSI] illegal opcode */
 #define ILL_ILLTRP 2 /* [XSI] illegal trap */
 #define ILL_PRVOPC 3 /* [XSI] privileged opcode */
 #define ILL_ILLOPN 4 /* [XSI] illegal operand -NOTIMP */
 #define ILL_ILLADR 5 /* [XSI] illegal addressing mode -NOTIMP */
 #define ILL_PRVREG 6 /* [XSI] privileged register -NOTIMP */
 #define ILL_COPROC 7 /* [XSI] coprocessor error -NOTIMP */
 #define ILL_BADSTK 8 /* [XSI] internal stack error -NOTIMP */
 #define CLD_EXITED

What's the best thing to do here? I've actually compiled against
FreeBSD 7's signal.h just to get me through this but the fact is the
kernel (trap.c) does not set these codes. Will this cause Boost to
crap out on me during runtime? If so, is there a workaround since
this seems like a real bug in portability?

- SIGPOLL is not defined, its SIGIO (I can work around this)

- The Boost build when doing its standard tests sets up the
LD_LIBRARY_PATH on my box as:


- ICU for FreeBSD is in /usr/include/local which causes the build.jam
stuff to miss autodetecting it

On a 64-bit machine, adding /usr/lib32 BREAKS not only the test but
most natively compiled binaries - I had to move /usr/lib32 and rename
it for some of the tests to work (like boost_std_no_locale) etc.

I started a thread on Boost-Build but got no replies. I'm just
wondering how portable the latest release of Boost is on FreeBSD?
Btw, there are several files I had to patch within boost to even get
it to build relatively far (and I haven't tried python support just
yet). The current BSD port is 1.34 and has been that for a long time
(there was a 1.35 release at some point in beta testing) but I would
like to update it to 1.36 but need some guidance on the above.

Any guidance would be much appreciated...
