[MSW] Bundled wx-config and oleacc library

Postby PB_ » Sun Jul 09, 2017 5:59 pm

(I am not a CodeLite user, so I may have missed something obvious, sorry for that)


I installed CodeLite (v10.0.6, Windows Installer 64 bit) and created a project using "Executable (wxWidgets enabled)" project template. I built wxWidgets GIT master with MinGW (5.3) and set wxcfg in the CodeLite Project Settings/Environment/Additional Environment Variables for the debug configuration to "gcc_lib/mswud". When building the project I ended up with errors:
Code: Select all

Default MSW build of wxWidgets master has required linking with oleacc library for some time now, see

I have tried to add oleacc to Project Settings/Global Settings/Linker/Libraries but it did not help (probably because of the library order on the command line). I managed to work around the issue by appending ";-loleacc" in Project Settings/Linker/Linker Options.

Perhaps it would be a good idea to make the bundled wx-config to always output oleacc library for the MinGW builds? The wx-config has the code
Code: Select all
if (sho["wxUSE_OLE"])
   po["__LIB_OLEACC_p"] = addLib("oleacc"); // NOTE: not being used

But for some reason the build.cfg file never contains USE_OLE (nor USE_ACCESSIBILITY) even when the matching setup.h contains "#define wxUSE_OLE 1"?!

Thanks for reading this long post.

BTW, the project builds just fine with DLL build of wxWidgets, e.g. wxcfg=gcc_dll/mswud.
