My env is: DEVCPP, MINGW32, wxWindows 2.3.2
I changed the setup.h so wxUSE_ODBC = 1
I added the following code fragment to my project:
// obtain DB-connection with default user & DB
wxDbConnectInf *DbConnectInf = NULL;
DbConnectInf = new wxDbConnectInf(NULL,"MySQL5","joe", "-------");
if (!DbConnectInf || !DbConnectInf->GetHenv())
{
wxMessageBox("Unable to allocate an ODBC environment handle",
"DB CONNECTION ERROR", wxOK | wxICON_EXCLAMATION);
}
else
{
wxMessageBox("Connected",
"...", wxOK | wxICON_EXCLAMATION);
// The program is now ending, so we need to close
// any cached connections that are still being
// maintained.
wxDbCloseConnections();
// Release the environment handle that was created
// for use with the ODBC datasource connections
delete DbConnectInf;
}
after compilation I get linker errors:
[Linker error] undefined reference to `wxDbConnectInf::wxDbConnectInf(void*, wxString const&, wxString const&, wxString const&, wxString const&, wxString const&, wxString const&)'
[Linker error] undefined reference to `wxDbCloseConnections()'
[Linker error] undefined reference to `wxDbConnectInf::~wxDbConnectInf()'
How do I rebuild wx-library so the DB/ODBC support will be included?
(I just can't find the propare make file)
or maybe it's not the library and there is some other problem?
My project settings:
C++ Compiler parameters:
-DWINVER=0x0400 -D__WIN95__ -D__GNUWIN32__ -D__WIN32__ -DHAVE_W32API_H -D__WXMSW__ -D__WINDOWS__ -Wall -fno-pcc-struct-return -O2 -Os -fno-rtti -fno-exceptions
Linker:
-Wl,--subsystem,windows -mwindows -lwxmsw -lstdc++ -lgcc -lodbc32 -lwsock32 -lwinspool -lwinmm -lshell32 -lcomctl32 -lctl3d32 -ladvapi32 -lopengl32 -lglu32 -lole32 -loleaut32 -luuid
anyone?
