| 13 | REQUIREMENTS
|
|---|
| 14 |
|
|---|
| 15 | In order to compile the Qt library, you will need the following tools:
|
|---|
| 16 |
|
|---|
| 17 | - One of the OS/2 Warp 4, OS/2 Warp 4.5 or eComStation operating systems.
|
|---|
| 18 |
|
|---|
| 19 | - InnoTek GCC compiler version 3.3.5 CSD3 or above (not tested).
|
|---|
| 20 | You can download a copy of the compiler using the following link:
|
|---|
| 21 |
|
|---|
| 22 | ftp://ftp.netlabs.org/pub/gcc/GCC-3.3.5-csd3.zip
|
|---|
| 23 |
|
|---|
| 24 | - Patched OpenWatcom linker which you can download from:
|
|---|
| 25 |
|
|---|
| 26 | ftp://ftp.netlabs.org/pub/gcc/wl-hll-r1.zip
|
|---|
| 27 |
|
|---|
| 28 | Note that if you use IBM ILINK (no matter what version), you will
|
|---|
| 29 | not be able to build the debug version of the library due to
|
|---|
| 30 | bugs/limitations of ILINK.
|
|---|
| 31 |
|
|---|
| 32 | - GNU Make 3.81beta1 or above (not tested) available at:
|
|---|
| 33 |
|
|---|
| 34 | http://unix.os2site.com/pub/binary/make/make-3_81beta1-bin-static.zip
|
|---|
| 35 |
|
|---|
| 36 | After unpacking the GCC archive, you will have to set up the compiler
|
|---|
| 37 | environment by invoking gccenv.cmd from the bin subdirectory with the
|
|---|
| 38 | correct arguments (type gccenv.cmd -? for help). For the OpenWatcom
|
|---|
| 39 | linker, specify WLINK as the second argument. You will also need to perform
|
|---|
| 40 | the following steps:
|
|---|
| 41 |
|
|---|
| 42 | - Make sure the selected linker and the make utility are in PATH.
|
|---|
| 43 |
|
|---|
| 44 | - Make sure CMD.EXE is your command line processor (the generated makefiles
|
|---|
| 45 | will rely on its 'copy', 'if' and other commands).
|
|---|
| 46 |
|
|---|
| 47 | - set LIBRARY_PATH=C:\OS2\DLL;C:\MPTN\DLL where C: is your boot drive.
|
|---|
| 48 |
|
|---|
| 49 | Note that the QTDIR environment variable used by previous Qt versions is not
|
|---|
| 50 | used by Qt4 anymore (except two rare cases that do not affect the OS/2 platform
|
|---|
| 51 | anyway and are probably leftovers after the migration of the qmake feature
|
|---|
| 52 | specifications to Qt4). Therefore, there is no need to set this variable
|
|---|
| 53 | explicitly. See a note below about
|
|---|
| 54 |
|
|---|
| 55 | There is also no need to set the QMAKESPEC variable explicitly. If it is absent,
|
|---|
| 56 | qmake will use the specification stored in the <Qt4_Home>/mkspecs/default
|
|---|
| 57 | directory, which on OS/2 always refers to the "os2-g++" specification, the only
|
|---|
| 58 | one supported at the present time.
|
|---|
| 59 |
|
|---|
| 60 | When the environment is set up, go to the directory where you unpacked the
|
|---|
| 61 | Qt4 source tree and type:
|
|---|
| 62 |
|
|---|
| 63 | configure.cmd
|
|---|
| 64 |
|
|---|
| 65 | This will set up the library (create necessary configuration and include files)
|
|---|
| 66 | and build the qmake utility.
|
|---|
| 67 |
|
|---|
| 68 | The next step is to go to the src subdirectory and type:
|
|---|
| 69 |
|
|---|
| 70 | make
|
|---|
| 71 |
|
|---|
| 72 | This will compile and link the library. Note that by default both the release
|
|---|
| 73 | and the debug version of the library are built (please be patient, it may take
|
|---|
| 74 | quite some time depending on your hardware). The release and debug libraries can
|
|---|
| 75 | co-exist in the same source tree and may be used in parallel: all the debug DLLs
|
|---|
| 76 | get a 'd' letter in their name preceeding the Qt major version number and use
|
|---|
| 77 | separate directories for object files.
|
|---|
| 78 |
|
|---|
| 79 | To save time, you may also build the release and the debug versions of the
|
|---|
| 80 | library separately by typing 'make release' or 'make debug' accordingly
|
|---|
| 81 | instead of just 'make'.
|
|---|
| 82 |
|
|---|
| 83 | Once the library is successfully built, you may try to compile the demos
|
|---|
| 84 | and examples by visiting the individual example subdirectories in the source
|
|---|
| 85 | tree and typing 'qmake' followed by one of 'make', 'make release' or
|
|---|
|
|---|
