|

|

| 12 | please see the CHANGES.OS2 file included in this distribution.
|
|---|
| 13 |
|
|---|
| 14 | Please note that this version is binary incompatible with previous versions of
|
|---|
| 15 | Qt 4 for OS/2! This is not a behavior of the original Qt library (where versions
|
|---|
| 16 | with the same major number are usually binary compatible), but it is due to the
|
|---|
| 17 | fact that we continue to add missing features to the OS/2 version ot Qt and this
|
|---|
| 18 | cannot be done witout breaking the binary compatibility. On practice, this means
|
|---|
| 19 | that you need to recompile your applications with the new version of the Qt
|
|---|
| 20 | library in order to make them work with it.

| 24 | REQUIREMENTS
|
|---|
| 25 |
|
|---|
| 26 | In order to compile the Qt library and Qt-based applications, you will need
|
|---|
| 27 | the following tools:
|
|---|
| 28 |
|
|---|
| 29 | - One of the OS/2 Warp 4, OS/2 Warp 4.5 or eComStation operating systems.
|
|---|
| 30 |
|
|---|
| 31 | - GCC compiler version 4.4.2 for OS/2, patched OpenWatcom linker and
|
|---|
| 32 | GNU Make 3.81beta1 or above. The GCC compiler must be set up to use the
|
|---|
| 33 | OpenWatcom linker for linking.
|
|---|
| 34 |
|
|---|
| 35 | If you do not have a working GCC environment with the above requirements, it
|
|---|
| 36 | is recommended to download a ready-to-use GCC 4.2.2 distribution from here:
|
|---|
| 37 |
|
|---|
| 38 | ftp://ftp.netlabs.org/pub/qt4/gcc-4_4_2-complete-20091205.zip
|
|---|
| 39 |
|
|---|
| 40 | This distribution includes all tools necessary to compile and build the Qt
|
|---|
| 41 | library from the source code. Just follow the installation instructions
|
|---|
| 42 | contained in the README file inside this ZIP archive to set up the GCC
|
|---|
| 43 | environment.
|
|---|
| 44 |
|
|---|
| 45 | Please note that starting from Qt 4.6.2, support for GCC 3.3.5 and earlier
|
|---|
| 46 | versions of the compiler has been dropped and the Qt library will most
|
|---|
| 47 | likely not build if you use one of these compilers. Later versions prior to
|
|---|
| 48 | GCC 4.4.2 may work but they are not tested and not supported.
|
|---|
| 49 |
|
|---|
| 50 | - IBM RC (Resource Compiler) Version 5.00.007 (comes with OS/2 Toolkit 4.5)
|
|---|
| 51 | or Version 4.00.011 (comes with eCS 2.0). Other versions may not work
|
|---|
| 52 | correctly.
|
|---|
| 53 |
|
|---|
| 54 | There is also a set of optional tools which are necessary to enable the selected
|
|---|
| 55 | features of the Qt library. If these tools are missing, the Qt configuration
|
|---|
| 56 | script (discussed in section "COMPILING QT" below) will automatically disable
|
|---|
| 57 | the corresponding feature:
