[bug] QNX SDP 7.0 debug build with stabs

[Johnnyxy]

Hi there,
while compiling code with QNX SDP 7.0 (GCC 5.4) I get an error:

qcc.compile.c++ C:\boost\bin.v2\libs\thread\build\qcc-5.4\dbg\lnk-sttc\trgt-os-qnxnt\thrdp-pthrd\vsblt-hdn\future.o

I investigated the problem and found out that the qcc.jam specifies the -gstabs+ flag.

build/src/tools/qcc.jam

Line 51 in a83f94a

toolset.flags qcc.compile OPTIONS <debug-symbols>on : -gstabs+ ;

build/src/tools/qcc.jam

Line 167 in a83f94a

toolset.flags qcc.link OPTIONS <debug-symbols>on : -gstabs+ ;

The QCC compiler wrapper docs describe only -g as compiler argument (see QNX 7.0, QNX 6.5).

I have patched the file with the attached patch file (locally):
boost_build_qcc_fix_debug_build_parameter.patch.txt

Thank you for your contributions. Main development of B2 has moved to https://github.com/bfgroup/b2
This issue has been automatically marked as "transition" to indicate the potential for needing transition to the new B2 development project.
