I'm getting problems with g++ library compiling in QNX 6.5.0 When I compile a program /src/gcc-4.6-20110212/nto-x86/i486-pc-nto-qnx6.5.0/libstdc++-v3/src/parallel_settings.cc I get an error: xgcc: error: unrecognized option '-pthread' When I use the -v and -save-temps the result is as follows: Reading specs from /src/gcc-4.6-20110212/nto-x86/./gcc/specs COLLECT_GCC=/src/gcc-4.6-20110212/nto-x86/./gcc/xgcc COLLECT_LTO_WRAPPER=/src/gcc-4.6-20110212/nto-x86/./gcc/lto-wrapper xgcc: error: unrecognized option '-pthread' Target: i486-pc-nto-qnx6.5.0 Configured with: ../configure with_gmp=/usr/pkg --srcdir=.. --enable-cheaders=c --with-as=/usr/qnx650/host/qnx6/x86/usr/bin/ntox86-as --with-ld=/usr/qnx650/host/qnx6/x86/usr/bin/ntox86-ld --with-sysroot=/usr/qnx650/target/qnx6/ --disable-werror --libdir=/usr/qnx650/host/qnx6/x86/usr/lib --libexecdir=/usr/qnx650/host/qnx6/x86/usr/lib --target=i486-pc-nto-qnx6.5.0 --srcdir=/src/gcc-4.6-20110205/nto-x86-o-ntox86/.. --prefix=/usr/qnx650/host/qnx6/x86/usr --exec-prefix=/usr/qnx650/host/qnx6/x86/usr --with-local-prefix=/usr/qnx650/host/qnx6/x86/usr --enable-languages=c,ada,c++,objc,obj-c++,fortran --enable-threads=posix --enable-libada --disable-nls --enable-libssp --disable-tls --with-ppl=/usr/local --enable-libgomp --enable-libffi --enable-libmudflap --enable-__cxa_atexit --disable-libstdcxx-pch --with-gxx-include-dir=/usr/include/c++/4.6.0 --enable-multilib --with-bugurl=http://www.qnx.com --with-included-gettext --program-suffix=-4.6.0 --enable-version-specific-runtime-libs --enable-shared --disable-bootstrap CC=i486-pc-nto-qnx6.5.0-gcc CPPFLAGS=' -I/usr/qnx650/target/qnx6/usr/include' LDFLAGS= CXX=i486-pc-nto-qnx6.5.0-g++ AUTOMAKE=: AUTOCONF=: AUTOHEADER=: AUTORECONF=: ACLOCAL=: Thread model: posix gcc version 4.6.0 20110205 (experimental) (GCC) COLLECT_GCC_OPTIONS='-v' '-save-temps' '-shared-libgcc' '-B' '/src/gcc-4.6-20110212/nto-x86/./gcc' '-nostdinc++' '-L/src/gcc-4.6-20110212/nto-x86/i486-pc-nto-qnx6.5.0/libstdc++-v3/src' '-L/src/gcc-4.6-20110212/nto-x86/i486-pc-nto-qnx6.5.0/libstdc++-v3/src/.libs' '-B' '/usr/qnx650/host/qnx6/x86/usr/i486-pc-nto-qnx6.5.0/bin/' '-B' '/usr/qnx650/host/qnx6/x86/usr/i486-pc-nto-qnx6.5.0/lib/' '-isystem' '/usr/qnx650/host/qnx6/x86/usr/i486-pc-nto-qnx6.5.0/include' '-isystem' '/usr/qnx650/host/qnx6/x86/usr/i486-pc-nto-qnx6.5.0/sys-include' '-I' '/src/gcc-4.6-20110212/nto-x86/i486-pc-nto-qnx6.5.0/libstdc++-v3/include/i486-pc-nto-qnx6.5.0' '-I' '/src/gcc-4.6-20110212/nto-x86/i486-pc-nto-qnx6.5.0/libstdc++-v3/include' '-I' '/src/gcc-4.6-20110205/libstdc++-v3/libsupc++' '-fno-implicit-templates' '-Wall' '-Wextra' '-Wwrite-strings' '-Wcast-qual' '-fdiagnostics-show-location=once' '-ffunction-sections' '-fdata-sections' '-g' '-O2' '-fopenmp' '-D' '_GLIBCXX_PARALLEL' '-I' '/src/gcc-4.6-20110212/nto-x86/i486-pc-nto-qnx6.5.0/libstdc++-v3/../libgomp' '-c' '-fPIC' '-shared' '-D' 'PIC' '-o' '.libs/parallel_settings.o' '-mtune=i486' '-march=i486' '-pthread' Please help.
