This is an unstable +development release and OS/2 is considered to be in beta. + +IMPORTANT NOTE: If you experience problems installing, please +re-read this instructions and other related files (changes.txt, +readme.txt, notes on the Web site) carefully before mailing +wx-users or the author. Preferably, try to fix the problem first and +then send a patch to the author. Please report bugs using the +bug report form on the wxWidgets web site. + +Unarchiving +----------- + +At this time there is no comprehensive setup.exe type installation program. +wxWidgets for OS/2 requires you download various .zip files and unpack them +to your desired location on your system. Pick a location say, +C:\wx\wxWidgets-2.8.0, copy the .zip files to there and unzip them ensuring you +unzip the subdirectories as well. You will need: + +- All common, generic and OS2-specific wxWidgets source; +- samples; +- documentation in HTML Help format; +- makefiles for VisualAge V3.0 (possibly for EMX and Watcom C++); +- JPEG, TIFF, PNG, ZLIB, wxSTC, REGEX, EXPAT library sources. + +All but the documentation is included in wxOS2-2.8.0.zip, documentation +must be downloaded separately from the wxWidgets Web site. + + +General installation notes +-------------------------- + +After unzipping everything your directory tree should look something like +this: + +x:\wx\wxWidgets-2.8.0\docs (your HTML reference manual) +x:\wx\wxWidgets-2.8.0\include\wx +x:\wx\wxWidgets-2.8.0\include\wx\generic +x:\wx\wxWidgets-2.8.0\include\wx\html +x:\wx\wxWidgets-2.8.0\include\wx\os2 +x:\wx\wxWidgets-2.8.0\samples\.... (all the sample directories) +x:\wx\wxWidgets-2.8.0\src +x:\wx\wxWidgets-2.8.0\src\common +x:\wx\wxWidgets-2.8.0\src\generic +x:\wx\wxWidgets-2.8.0\src\html +x:\wx\wxWidgets-2.8.0\src\jpeg +x:\wx\wxWidgets-2.8.0\src\os2 +x:\wx\wxWidgets-2.8.0\src\png +x:\wx\wxWidgets-2.8.0\src\tiff +x:\wx\wxWidgets-2.8.0\src\zlib + +If you are using VisualAge, you will also need to ensure you have a +\lib directory as well, x:\wx\wxWidgets-2.8.0\lib +and you will have to set a WXWIN environment variable in your +config.sys, +SET WXWIN=X:\WX\WXWINDOWS-2.8.0; + +Compilation +----------- + +For now, only VisualAge V3.0 FP 8 and EMX-0.9d (with fix4) are supported. +However, the library has been successfully compiled with Watcom C++ as +well. As those build environments get a bit more "formalized", I will add +them here. + +Compilation with VisualAge on the one hand and EMX on the other hand are +rather different, VisualAge is essentially following Windows' way of doing +it, EMX is following the example of the unix ports. + +Compilation with VisualAge +-------------------------- + +In addition to VisualAge V3.0 Fixpack 8 you will need the following in order +to successfully build and use wxWidgets for OS/2: + +1. IBM OS/2 Toolkit Version 4.5 or later +2. IBM TCPIP V4.0 or later +3. You will need the IBMLAN Lan Requester service and UPM if you wish to use + network based components of the library (generally a standard part of any + Warp Connect 3.0 or Warp 4.0 installation. +4. I strongly suggest that you have the latest IBM fixpacks installed for + all your components. + +Go to the \src directory and open the file, makeva.env (there should be a +.env for each supported compiler when they are fully supported), for edit. +This is where the "make" environment for wxOS2 is set. Locate UMPLIB, NETLIB, +and TCPIP environment variables about 20 lines down. Set these to match +your system. + +There are number of possible outputs you can produce. There is a static +lib and a dynamically linked lib, and both can be built in debug or release +mode. Since wxOS2 is a beta and a rough one at that, I suggest, for now, +you stick to the debug builds. The resultant linkable binaries will be +output to the \lib directory as will the .dll files. The statically linked +lib will be named wx.lib. Each of the third party libs will be there as well, +including png.lib, jpeg.lib, tiff.lib, and zlib.lib. For DLL builds the +import libs will have the same name, only with a 'd' appended. Thus the +import library for the main lib in a dll build is wxd.lib. + +Object modules will be output into paths dictated by the build mode. For +example, for debug static the outputs will be in DebugOS2, for DLLs in +DebugOS2DLL. + +For your first build, you can directly build the library. For subsequent +builds you will want to "clean" the output paths. To build the static library +go to \src and execute nmake all -f makefile.va. To clean out the outputs +execute nmake clean -f makefile.va. + +To build the wx.dll execut nmake all -f makefile.va WXMAKINGDLL=1. To clean +the outputs execute namek clean -f makefile.va WXMAKINGDLL=1. For +VisualAge 3.0 we use the module definition file method. + +If, for some reason you encounter linking problems with your dll build you may +need to rebuild the module definition file, wx23.def, found in \src\os2. To +do this you need to have a static version built. Go to the \lib directoy and +execute CPPFILT /B /P wx.lib>temp.def. Copy this file to \src\os2. Delete +the temp.def from your \lib directory. + +I find the following to be the easiest to reconstruct the .def file. Open +both the wx23.def and the temp.def file. Copy the header of the wx23.def to +the clipboard and paste it into the top of the temp.def file. If you have +a valid SQL database client with its SDK on your system you can skip the next +step. wxWidgets included some ODBC and SQL modules. They expect the standard +sql.h and such to available. If you do not have a database client with its +SDK (such as DB/2) then for the .dll build you need to delete the exports for +the following three modules from your temp.def file, db.cpp, dbgrid.cpp and +dbtable.cpp. save you changes to temp.def. Delete wx23.def and rename your +temp.def to wx23.def and you are ready to go. + +I hope to clean up the .dll builds at some point before the library is +a full fledged production caliber product. Fortunately EMX and Watcom can use +the import and export pragmas successfully negating the need for manual .def +files. VA 3.0, unfortunately in C++ does not properly export the mangled +names so we are stuck with the CPPFILT .def file method of .dll builds for +now. + +When building an application that uses the wx.dll you need to build it using +the WXUSINGDLL=1 macro. For example to build the minimal sample you would +go to \samples\minimal and execute nmake all -f makefile.va WXUSINGDLL=1. + +I strongly suggest when developing apps using wxWidgets for OS/2 under old +VisualAge 3.0, that you use the dynamically linked library. The library is +very large and even the most trivial statically linked .exe can be very +large and take a long time to link. The release builds are much smaller, +however. Fortunately, EMX seems to build much smaller static executables. + +Compilation using EMX +--------------------- + +In addition to EMX-0.9d you will need a rather complete Unix-like +environment, starting with a shell (e.g. ash) and most of the +GNU file/text/shell utilities, but also flex, bison, sed, grep, awk +and GNU make. Particularly note that uname is relevant to get the +configure script working - the one from GNU shell utilities 1.12 +does work (check that uname -s returns "OS/2" and uname -m returns "i386" +and you should be mostly fine. + +The first thing to do is to decide on a build directory. You can either +do in-tree builds or you can do the build in a directory separated from +the source directory. The later has the advantage, that it is much easier +to compile and maintain several ports of wxWidgets on OS/2 - if you are +developping cross-platform applications you might want to compile (and +update) e.g. wxGTK or wxX11 as well. + +In the following, let's assume you decided to build in +\wx\wxWidgets-2.8.0\build\pm. Now we need to set some environment +variables, namely MAKESHELL (to a Unix like shell, let's assume ash) +and INSTALL (to point to the install script. If you omit this, configure +might find something like the system's tcpip\pcomos\install.exe which will +not do the thing you want), e.g. +SET MAKESHELL=ash +SET INSTALL=/wx/wxWidgets-2.8.0/install-sh -c + +Be warned that depending on the precise version of your make, the +variable that needs to be set might be MAKE_SHELL instead of MAKESHELL. +If you have a really deficient version of GNU make, it might even be +necessary to set SHELL or even COMSPEC to a unix like shell as well. + +Now run the provided configure script by executing e.g. +`ash -c "../../configure \ + --prefix=directory_where_you_want_wxWidgets_to_be_installed"' +from within the build directory (the relative path might be different +depending on the build directory you selected). +If you are already running some unix-like shell and not cmd, you may +of course ommit the `ash -c' part in the above command. +This will create a whole directory structure containing lib and sample +directories which each essentially contain a suitable makefile. + +Calling `make' now should start a compile run which hopefully ends +with a library being placed in the lib subdirectory. + +Now you can change in the samples subdirectory and call make to compile +all samples, however currently not all will work on OS/2, so you might +prefer to change into the directory of a specific sample +(e.g. samples\minimal) and call make there to just build this one example. +Essentially, each sample that's not working indicates an area, where help +in porting wxWidgets to OS/2 would be appreciated. + +Finally, you can run `make install' which should install wxWidgets to +the desired place. +Note that we also install the wx-config script which wants to help you +compiling your own applications, e.g. `wx-config --cxxflags` will emit the +flags that are needed for compiling source code which includes wxWidgets +headers, `wx-config --libs` will emit the flags needed for linking against +wxWidgets (wx-config is assuming you are calling it from a unix-like shell!). + +For building a DLL, the only supported way currently is to first build the +static library and then use Andrew Zabolotny's dllar.cmd. However, this +works quite nicely. + +Finally, if you also want to build a different port, e.g. wxGTK, you +essentially have to use the procedure described above, the only difference +being that you have to pass a switch to configure indicating which port +to build. If you do not do this in a separate build directory (e.g. +\wxWidgets-2.8.0\build\gtk), you'll have to do a `make clean' first. +The magical switches that have to be passed to configure for the various +ports are --with-gtk (wxGTK), --with-motif (wxMotif), --with-x11 (wxX11), +and --disable-gui (wxBase). Note that contrary to the native, PM based +OS/2 port, all of those ports work slightly better with POSIX/2's cExt +library. If include and library path include the suitable paths, -lcExt +is automatically appended to the linker flags by the configure script.
