Installing wxWindows 2.3.3
--------------------------
This is wxWindows 2.3.3 for IBM OS/2 Warp3 and Warp4. 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 wxWindows web site.
Unarchiving
-----------
At this time there is no comprehensive setup.exe type installation program.
wxWindows 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\wxWindows-2.3.3, 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 wxWindows source;
- samples;
- documentation in HTML Help format;
- makefiles for VisualAge V3.0 (possibly for EMX and Watcom C++);
- HTML library source;
- JPEG library source;
- TIFF library source;
- PNG library source;
- ZLIB library source;
All but the documentation is included in wxOS2-2.3.3.zip, documentation
must be downloaded separately from the wxWindows Web site.
Other add-on packages are available from the wxWindows Web site, such as:
- mmedia.zip. Audio, CD, video access for Windows and Linux.
- ogl3.zip. Object Graphics Library: build network diagrams, CASE tools etc.
- tex2rtf3.zip. Tex2RTF: create Windows Help, HTML, and Word RTF files from
the same document source.
General installation notes
--------------------------
After unzipping everything your directory tree should look something like
this:
x:\wx\wxWindows-2.3.3\docs (your HTML reference manual)
x:\wx\wxWindows-2.3.3\include\wx
x:\wx\wxWindows-2.3.3\include\wx\generic
x:\wx\wxWindows-2.3.3\include\wx\html
x:\wx\wxWindows-2.3.3\include\wx\os2
x:\wx\wxWindows-2.3.3\samples\.... (all the sample directories)
x:\wx\wxWindows-2.3.3\src
x:\wx\wxWindows-2.3.3\src\common
x:\wx\wxWindows-2.3.3\src\generic
x:\wx\wxWindows-2.3.3\src\html
x:\wx\wxWindows-2.3.3\src\jpeg
x:\wx\wxWindows-2.3.3\src\os2
x:\wx\wxWindows-2.3.3\src\png
x:\wx\wxWindows-2.3.3\src\tiff
x:\wx\wxWindows-2.3.3\src\zlib
If you are using VisualAge, you will also need to ensure you have a
\lib directory as well, x:\wx\wxWindows-2.3.3\lib
and you will have to set a WXWIN environment variable in your
config.sys,
SET WXWIN=X:\WX\WXWINDOWS-2.3.3;
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 inorder
to successfully build and use wxWindows 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. wxWindows 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 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 wxWindows 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.
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 wxWindows 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\wxWindows-2.3.3\build\pm. Now we need to set some environment
variables, namely MAKE_SHELL (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 MAKE_SHELL=ash
SET INSTALL=/wx/wxWindows-2.3.3/install-sh.
Now run the provided configure script by executing e.g.
`ash -c "../../configure \
--prefix=directory_where_you_want_wxWindows_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 wxWindows to OS/2 would be appreciated.
Finally, you can run `make install' which should install wxWindows 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 wxWindows
headers, `wx-config --libs` will emit the flags needed for linking against
wxWindows (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.
\wxWindows-2.3.3\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.
