  No, I compiled the libraries myself, actually rebuilt severaltimes, the program
code has 5 sub dirs which have code that interfaces & build prperly with the libs
in question. The sub dirs are themselves a set of libraries. The libs I am trying
to use are a wxWidgets gui platform. The code I have developed has copiled and ran
6 weeks ago under a last version of this build system. My build system is called
Scons, a python based sw build system. I have gotten all to coile and build
properly now upto the final step of linking everything to gether. The eror is
undfined resolution as below:
mainframe.o(.text+0x420): In function
`CMainFrame::CMainFrame[not-in-charge](wxWindow*, int, wxString const&, wxPoint
const&, wxSize const&, long)': /swdev/dnr/2.5.3/silverwareIDE/mainframe.cpp:203:
undefined reference to `wxObject::operator new(unsigned long, char const*, int)'
mainframe.o(.text+0x6fb):/swdev/dnr/2.5.3/silverwareIDE/mainframe.cpp:226:

mainframe.o(.text+0x1517):/swdev/dnr/2.5.3/silverwareIDE/mainframe.cpp:226: more
undefined references to `wxObject::operator new(unsigned long, char const*, int)'
follow mainframe.o(.text+0x583f): In function
`__static_initialization_and_destruction_0':
/usr/local/include/wx-2.5/wx/memory.h:327: undefined reference to
`wxDebugContextDumpDelayCounter::wxDebugContextDumpDelayCounter[in-charge]()'

link :
g++ -o silverware mainframe.o classviewframe.o silverwareIDE.o
 -L/usr/local/lib -Llib/debug -L/usr/X11R6/lib64 -lwx_based-2.5
 -lwx_based_net-2.5 -lwx_gtk2d_core-2.5 -lwx_gtk2d_svg-2.5 -lwx_gtk2d_adv-2.5
 -lwx_gtk2d_animate-2.5 -lwx_gtk2d_xrc-2.5 -lregistryD -lwidgetsD -lide_editD
 -ldlgsD -lviewsD -lideutilityD -lX11 -lXpm -lXext -lpthread
 
The unresolved are located in a lib named libwx_based-21.5.so in my /usr/local/lib
dir. The ldconfig -v finds it and all of the wxWidget libs there.  The
/etc/ld.so.conf has all lib dirs listed and the compile/link has the dirs need
listed in the -L. I have compiled the samples programs with wxWidgets and they
work. I have created a test program with KDevelop 3.1 using wxWidgets and it
works. My program does not use a IDE to create and run,  just n editor to code and
a terminala to build. I have also used the above link on a cmdline in a terminal
and got the same results.

cheers
