Tclkit HP-UX notes

2003-12-22 - notes by Bob Techentin, Tclkit 8.4.5

  O/S:  HP-UX B.11.00
  Environment
    CC="cc"
    CFLAGS="-Ae +DAportable +Onolimit -O"
    CXX="aCC"
    CXXFLAGS="+DAportable -O"
  gentkit.local - maps gcc/g++ to native cc/aCC compilers
     array set X {
          gcc "cc -Ae +DAportable +Onolimit -O"
          g++ "aCC +DAportable -O"
     }

The build went smoothly - at least as smoothly as before. Genkit still fails for me at line 373, because "gzip | tar" returns a non-zero value on our HP systems. Adding a catch fixes this problem.

  Ok, I've added a catch and a check that the expected dir exists after this.  -jcw

I also forced the build to use the native HP compilers by defining CC, CFLAGS, CXX, and CXXFLAGS environment variables, then wrote similar values to genkit.local for gcc and g++. I used the native flags "-Ae" for ANSI C, +DAportable" for PA-RISC 1.1 and 1.2 architectures, and "-O" and "+Onolimit" for optimization.

the loader looks for the shared library "libtk8.4.sl" which is not there

        -- mea culpa, I'm fixing my "post-build" steps to better deal with this (jcw)

the linking of the main executable and the shared library is not consistent (V1.1 vs V2.0), here's my build:

        $ file tclkit-mae16 tclkit-mae16.vfs/lib/tk8.4/libtk8.4.sl
        tclkit-mae16:                           PA-RISC1.1 shared executable dynamically linked
        tclkit-mae16.vfs/lib/tk8.4/libtk8.4.sl: PA-RISC1.1 shared library

This is compiled on HP-UX 11.00 using HP's ANSI C compiler (cc) version 11.11.04 and HP's C++ compiler (aCC) version 3.33. The build used the +DAportable flag, so the executables should run on PA-RISC 1.x and 2.x processors.

built with genkit on B.11.00 with +DAportable, should work on pa-risc 2.0 and 1.1
Metakit has an #ifdef in src/fileio.cpp to avoid a very nasty mmap bug
