I have done the QNX4 port with the current source tree. The number of backend/Makefiles to be patched could significantly be reduced since they have been adopted to the QNX4 needs. Here are the completely new files: pgsql/src/template/QNX pgsql/src/makefiles/Makefile.qnx4 pgsql/src/include/port/qnx4.h pgsql/src/backend/port/dynloader/qnx4.h pgsql/src/backend/port/dynloader/qnx4.c pgsql/src/backend/port/qnx4/Makefile pgsql/src/backend/port/qnx4/ipc.h pgsql/src/backend/port/qnx4/isnan.c pgsql/src/backend/port/qnx4/rint.c pgsql/src/backend/port/qnx4/sem.h pgsql/src/backend/port/qnx4/sem.c pgsql/src/backend/port/qnx4/shm.h pgsql/src/backend/port/qnx4/shm.c pgsql/src/backend/port/qnx4/tstrint.c pgsql/src/backend/port/qnx4/tstsem.c pgsql/src/backend/port/qnx4/tstshm.c The following files have been extended with specific code: pgsql/src/configure.in pgsql/src/configure pgsql/src/config.guess pgsql/src/config.sub pgsql/src/include/storage/s_lock.h pgsql/src/backend/port/Makefile.in pgsql/src/backend/port/isinf.c The extension in s_lock.h is required for the Watcom compiler only. But nevertheless it should be included because this code has been tested and could be usefull for other new platforms. These files have been extended to avoid conflicts/problems: pgsql/src/include/utils/builtins.h pgsql/src/backend/postmaster/postmaster.c pgsql/src/test/regress/regress.sh The following files could be changed in general but to avoid potential problems on other platforms they have been extended with IFs. The mkdir problem can simply be solved with a preceeding "-". Obviously there is a problems with return codes on QNX. The "[ test ] && action" solution doesn't help since it has the same behaviour. pgsql/src/backend/Makefile pgsql/src/bin/scripts/Makefile pgsql/src/interfaces/libpgeasy/Makefile.in pgsql/src/interfaces/libpgtcl/Makefile.in pgsql/src/interfaces/libpq/Makefile.in pgsql/src/interfaces/libpq++/Makefile.in I have inserted a required #include again which has been kicked out since 6.5.2: pgsql/src/backend/storage/lmgr/proc.c The following Makefiles have been changed because the QNX archiver wlib crashes with bootstrap.o. These crashes depend on the code of the object files. It is not known when this happens. This problem comes and goes. In 6.5.2 ipc.o also caused a crash but with the current source not. So it could make sense not to change the related Makefiles in this matter because in following releases may be another behavior. Probably it would be better to address this problem in README.qnx4. The files ipc.h, sem.h and shm.h should be linked to /usr/include. The README.qnx4 will be updated after the QNX port has been included into the source tree. The files themselves will be sent to pgsql-patches. Andreas Kardos
