omniORB 3 for FreeBSD

For FreeBSD 3.2, the following information may be useful.

This information is provided by Andre Fornacon.

If you have questions regarding omniORB on FreeBSD send them to [email protected].

I compiled omniORB 2.7.1 on a FreeBSD 3.2 (RELEASE) system using the pthreads from libc , gnu make and egcs 1.1.2.

the config file for FreeBSD builds:

• omniORB 2.7.1 shared and static libraries
• omniORB utils linked static against the omniORB libs

  [ not enabled by default, edit x86_freebsd_3.2.mk to do so. - SLL ]

        CXXFLAGS = -D_REENTRANT -D_THREAD_SAFE
        CXXFLAGS += -D__x86__ -D__freebsd__ -D__OSVERSION__=3
        CXXFLAGS += -I<YOUR_OMNIORB_INSTALL_DIRECTORY>/include
    

        LDFLAGS = -L<YOUR_OMNIORB_DIRECTORY>/lib/x86_freebsd_3.2
        LDFLAGS += -lomniORB2 -lomniDynamic2 -ltcpwrapGK -lomnithread
        LDFLAGS += -Wl,-rpath,<YOUR_OMNIORB_DIRECTORY>/lib/x86_freebsd_3.2
    

        LDFLAGS = -L/lib/x86_freebsd_3.2
        LDFLAGS += -Wl,-Bstatic 
        LDFLAGS += -lomniORB2 -lomniDynamic2 -ltcpwrapGK -lomnithread
        LDFLAGS += -Wl,-Bdynamic
    

Note!link with the -lpthread flag

During the port I ran into the following problems:

• fcntl.h doesn't define O_SYNC, so i used O_FSYNC instead
  • omniORB-2.7.1/src/appl/omniNames/log.cc
  • omniORB-2.7.1/src/appl/omniNames/omniNames.cc
• need to include unistd.h and sys/wait.h on freebsd in
  • omniORB-2.7.1/src/tool/omniidl2/driver/drv_fork.cc
  • omniORB-2.7.1/src/tool/omniidl2/driver/drv_preproc.cc
• stock egcs 1.1.2 doesn't support the FreeBSD specific -pthread linking flag as the supplied gcc (2.7.2) does. just using -lc_r results into binaries linked against libc_r and libc. 'cause libc_r comes first it may work but isn't a good idea IMHO. so i modified the egcs-1.1.2/gcc/config/i386/freebsd-elf.h file the diff is attached below. apply it and rebuild egcs. [i rename the compiler drivers from gcc and g++ to egcs and egcs++ just to make sure i don't use the supplied system gcc/g++]
