The file prog-cc.m4 invokes RTEMS_GCC_PIPE. dnl check if the target compiler may use --pipe RTEMS_GCC_PIPE test "$rtems_cv_gcc_pipe" = "yes" && CC="$CC --pipe" but there is no comparable code in the prog-cxx.m4. Looks like an oversight and a patch is welcomed. Feel free to file a ticket and take a shot at fixing it. :) Thank you in advance. > Nice spot! --joel > > Best regards, > Mikhail > > _______________________________________________ > devel mailing list > devel@rtems.org > http://lists.rtems.org/mailman/listinfo/devel >
