Problem with compiling/linking the wxdba libraries in Code::Blocks

(1/1)

Hi all,

I have a little problem with compiling/linking the wxdba libraries in Code::Blocks.
At first I tried to compile the following code snippet and received an "undefined reference" error message:


--- Code: ---[...]
wxDbConnectInf *DbConnectInf;
DbConnectInf = new wxDbConnectInf(NULL, "DATABASE", "USERNAME", "PASSWORD");
wxDb sampleDB(DbConnectInf->GetHenv());
[...]

obj/Debug/DBconnectMain.o||In function `DBconnectFrame::DBconnect(wxCommandEvent&)':|
DBconnectMain.cpp|185|undefined reference to `wxDbConnectInf::wxDbConnectInf(void*, wxString const&, wxString const&, wxString const&, wxString const&, wxString const&, wxString const&)'|

--- End code ---

OK, so I added "wxdba" to "Link libraries" in the "Linker settings" tab (Settings / Compiler and debugger... / Global compiler settings) and "/usr/local/include" and "/usr/local/include/wxdba" to the "Search directories / Linker" tab.
Now the "undefined reference" doesn't occur any longer, but instead I get:


--- Code: ---cannot find -lwxdba

--- End code ---

But why? As far as I can say, the entries in the CB configuration mentioned above seem to bee correct:


--- Code: ---/usr/local/bin/wxdba-config
/usr/local/include/wxdba
/usr/local/include/wxdba/array_filter.h

Can anyone help?

Thanks & regards,

... hm, ok. At least a little(!) success:

I recompiled dba-1.4.1 and wxdba-1.4.1 and installed them again.
But this time i compiled them with "--enable-shared".
After this I added "dba", "wxdba-base" and "wxdba-gui" to "Linker Settings / Link libraries" in CB and tried to compile the program, again:


--- Code: ---Linking executable: bin/Debug/DBconnect
/usr/local/lib/libwxdba-base.so: undefined reference to `wxTimeSpan::Format(wchar_t const*) const'
/usr/local/lib/libwxdba-gui.so: undefined reference to `wxString::Format(wchar_t const*, ...)'
/usr/local/lib/libwxdba-gui.so: undefined reference to `wxStringBase::InitWith(wchar_t const*, unsigned long, unsigned long)'
/usr/local/lib/libwxdba-gui.so: undefined reference to `wxString::Find(wchar_t, bool) const'
/usr/local/lib/libwxdba-gui.so: undefined reference to `wxStringBase::ConcatSelf(unsigned long, wchar_t const*, unsigned long)'
/usr/local/lib/libwxdba-base.so: undefined reference to `wxStringBase::wxStringBase(unsigned long, wchar_t)'

/usr/local/lib/libwxdba-base.so: undefined reference to `wxDateTime::Format(wchar_t const*, wxDateTime::TimeZone const&) const'

--- End code ---

So, now it seems that the libraries are being found correctly, but what about the remaining "undefined reference" error messages?
How can I solve this?

Any ideas?

stahta01:
This is NOT an Code::Blocks question; but, are you using Unicode for both wxWidgets and wxDba as is required.

Edit1: I very strongly suggest turning on Full Compiler Logging; read the CB Wiki FAQ for directions.
Edit2: You do realize that the order of library matter in the linker step; make sure wxDba ones are correct relative to wxWidgets.
