| 16 | REQUIREMENTS
|
|---|
| 17 |
|
|---|
| 18 | In order to compile the Qt library and Qt-based applications, you will need
|
|---|
| 19 | the following tools:
|
|---|
| 20 |
|
|---|
| 21 | - One of the OS/2 Warp 4, OS/2 Warp 4.5 or eComStation operating systems.
|
|---|
| 22 |
|
|---|
| 23 | - InnoTek GCC compiler version 3.3.5 CSD3 or 4.4.2 (recommended).
|
|---|
| 24 | You can download the GCC 4.4.2 compiler using the following link:
|
|---|
| 25 |
|
|---|
| 26 | http://download.smedley.info/gcc-4.4.2-os2-20091205.zip
|
|---|
| 27 |
|
|---|
| 28 | GCC 4.4.2 requires newer binutils available at:
|
|---|
| 29 |
|
|---|
| 30 | http://download.smedley.info/binutils-2.19.1-os2-20090427.zip
|
|---|
| 31 |
|
|---|
| 32 | Note that in order to use the above version of GCC, you will also need
|
|---|
| 33 | to install the previous 3.x version (e.g. 3.3.5 CSD3) available at:
|
|---|
| 34 |
|
|---|
| 35 | ftp://ftp.netlabs.org/pub/gcc/GCC-3.3.5-csd3.zip
|
|---|
| 36 |
|
|---|
| 37 | - Patched OpenWatcom linker which you can download from here:
|
|---|
| 38 |
|
|---|
| 39 | ftp://ftp.netlabs.org/pub/gcc/wl-hll-r1.zip
|
|---|
| 40 |
|
|---|
| 41 | Note that if you use IBM ILINK (no matter what version), you will
|
|---|
| 42 | not be able to build the debug version of the library due to
|
|---|
| 43 | bugs/limitations of ILINK.
|
|---|
| 44 |
|
|---|
| 45 | - GNU Make 3.81beta1 or above (not tested) available at:
|
|---|
| 46 |
|
|---|
| 47 | http://unix.os2site.com/pub/binary/make/make-3_81beta1-bin-static.zip
|
|---|
| 48 |
|
|---|
| 49 | - LxLite 1.3.3 or above (not tested) if you want Qt DLLs and application
|
|---|
| 50 | executables to be compressed (to save hard disk space and load time). If
|
|---|
| 51 | you have a recent eComStation installation (e.g. 2.0 rc6) you will already
|
|---|
| 52 | have LxLite installed. Otherwise, you may take it from here:
|
|---|

|
|---|
| 57 |
|
|---|
| 58 | SETTING UP THE ENVIRONMENT
|
|---|
| 59 |
|
|---|
| 60 | After unpacking the GCC archive, you will have to set up the compiler
|
|---|
| 61 | environment by invoking gccenv.cmd from the "bin" subdirectory with the correct
|
|---|
| 62 | arguments (type gccenv.cmd -? for help). For the OpenWatcom linker, specify
|
|---|
| 63 | WLINK as the second argument.
|
|---|
| 64 |
|
|---|
| 65 | Please note that setting up the GCC 4.x environment requires some additional
|
|---|
| 66 | steps. Please look through the README files contained within the OS/2
|
|---|
| 67 | distribution.
|
|---|
| 68 |
|
|---|
| 69 | You will also need to perform the following steps:
|
|---|
| 70 |
|
|---|
| 71 | - Make sure the selected linker, the make utility and LxLite executable are
|
|---|
| 72 | in PATH.
|
|---|
| 73 |
|
|---|
| 74 | - Make sure CMD.EXE is your command line processor (the generated makefiles
|
|---|
| 75 | will rely on its 'copy', 'if' and other commands). If you have a Unix shell
|
|---|
| 76 | (SH.EXE) in your environment, you may need to force GNU make to use CMD.EXE
|
|---|
| 77 | by doing 'set MAKESHELL=C:\OS2\CMD.EXE' where C: is your boot drive.
|
|---|
| 78 |
|
|---|
| 79 | - Do set LIBRARY_PATH=C:\OS2\DLL;C:\MPTN\DLL where C: is your boot drive.
|
|---|
| 80 |
|
|---|
| 81 | - Make sure that there are no traces of any other Watcom or OpenWatcom
|
|---|
| 82 | installation in the environment where you build Qt as it will most likely
|
|---|
|
|---|
