Subject:   wxWidgets and unixODBC

Hi all,

I managed a compile of wxWidgets 2.6.1 with GCC 3.3.5 B4 that will use the
unixODBC for OS/2 port.

I did a configure with --with-odbc=sys and the environment variable
LDFLAGS set to (set LDFLAGS=-L m:/uodbc/lib) a value that would link in
the unixODBC link libraries. I also had to patch the configure file to use
_System when doing the test for the link with -lodbc

line 29068 changed from 
char SQLAllocEnv ();
to
char _System SQLAllocEnv ();

so that the configure test would find the correct symbol in odbc.lib. I
also generated an odbc.a file using emximp so that the configure test
would link.

emximp -o odbc.a odbc.lib

The header files from unixODBC have to  placed in the C_INCLUDE_PATH and
CPLUS_INCLUDE_PATH and the LIBRARY_PATH can be changed to include the
../lib directory from unixODBC.

In the makefile generated the CXFLAGS and CXXFLAGS values have the define
-DALLREADY_HAVE_OS2_TYPES 
added to eliminate an invalid redefinition created by the unixodbc
sqltypes.h file.
The sqltypes.h file from unixODBC has to be changed to eliminate a
redefinition of HINSTANCE on line 120

The dllnames.sh file also has to be changed to keep it from generating a
nine character name for the wxodbc26.dll file.

The change is 
from
    dllFile=`echo $dllFile | sed 's/base_\(...\)/b\1/'`
to
    dllFile=`echo $dllFile | sed 's/base_\(...\)/\1/'`
on line 11.

I have not done much testing but the dbtest sample program compiles, links
and does show the ODBC data sources correctly.
