IMPORTANT NOTE:
When sending bug reports tell us what version of wxWidgets you are
using (including the beta) and what compiler on what system. One

them concurrently. To do this, create a separate directory for each build
of wxWidgets - you may also want to create different versions of wxWidgets
and test them concurrently. Most typically, this would be a version configured
-with --enable-debug and one without. Note, that only one build can
-currently be installed with 'make install', so you'd have to use local version of
-the library for that purpose.

For building three versions (one GTK+, one Motif and a debug version of the GTK
source) you'd do this:
-md buildmotif
+mkdir buildmotif
cd buildmotif
../configure --with-motif
make
cd ..
-md buildgtk
+mkdir buildgtk
cd buildgtk
../configure --with-gtk
make
cd ..
-md buildgtkd
+mkdir buildgtkd
cd buildgtkd
../configure --with-gtk --enable-debug
make
cd ..
+Note that you can install all those libraries concurrently, you just need to
+pass the appropriate flags when using them.

* The simplest errors
---------------------
For any configure errors: please look at config.log file which was generated
during configure run, it usually contains some useful information.

very sure you have. Well, you have installed it, but you also have another
version of the GTK+ installed, which you may need to remove including other

location and configure can't find it there, so please check that your PATH

You get errors from make: please use GNU make instead of the native make
program. Currently wxWidgets can be built only with GNU make, BSD make and
library but not for your program - or due to using a compiler with optimisation
bugs.
-Linker complains about missing PROIO_yy_flex_alloc and similar symbols: you
-probably have an old version of flex, 2.5.4 is recommended.

* The simplest program

---------------
wxWidgets/GTK+ requires the GTK+ library to be installed on your system. It has
-to be a stable version, preferably version 1.2.10 (at least 1.2.3 is required,
-1.2.7 is strongly recommended).
+to be a stable version, preferably GTK+ 2.x.y, where x is an even number.
+GTK+ version 1.2 is highly discouraged, but if you decide to still use it,
+please use version 1.2.10 (at least 1.2.3 is required, 1.2.7 is strongly recommended).
You can get the newest version of the GTK+ from the GTK+ homepage at:
even older ones are expected to work most of the time.
You'll need OS/2 Warp (4.51) or eCS(1.0), X-Free86/2 (3.3.6 or newer),
-GTK+ (1.2.5 or newer), emx (0.9d fix 4), flex (2.5.4), yacc (1.8) or
-bison (1.25), a Unix like shell (pdksh-5.2.14 or ash), Autoconf (2.57),
-GNU file utilities (3.13), GNU text utilities (1.19),

GNU shell utilites (1.12), m4 (1.4), sed (2.05), grep (2.0), Awk (3.0.3),
GNU Make (3.75).
Presence of Posix/2 will be auto-detected.
Open an OS/2 prompt and switch to the directory above.
-Set MAKESHELL (and depending on your installation also INSTALL, for me
-it tends to try to use the system's tcpip\pcomos\install.exe which causes
-problems...) to a Unix like shell, e.g.
+Set MAKESHELL or MAKE_SHELL (which one is needed depends on the version of
+make) to a Unix like shell, e.g.
SET MAKESHELL=ash

-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.
+Depending on your installation you might want to also set INSTALL, for me
+it tends to try to use the system's tcpip\pcomos\install.exe which causes

Notice that the delivered configure scripts are fully OS/2 aware, so you
can simply run
- ash -c "configure --with-gtk"
+ ash -c "configure --with-gtk=1"
and make and possibly make install as described above.
* Building wxGTK on SGI
The SGI native compiler support has only been tested on Irix 6.5.
+* Building wxGTK on Cygwin
+--------------------------
+
+The normal build instructions should work fine on Cygwin. The one difference
+with Cygwin is that when using the "--enable-shared" configure option (which
+is the default) the API is exported explicitly using __declspec(dllexport)
+rather than all global symbols being available.
+
+This shouldn't make a difference using the library and should be a little
+more efficient. However if an export attribute has been missed somewhere you
+will see linking errors. If this happens then you can work around the
+problem by setting LDFLAGS=-Wl,--export-all-symbols. Please also let us know
+about it on the wx-dev mailing list.

Normally, you won't have to choose a toolkit, because when
you download wxGTK, it will default to --with-gtk etc. But

Using this way, a make file for the minimal sample would look
like this
