wxRichTextCtrl undefined reference

Post by coder99 » Tue Nov 19, 2019 6:39 am

Being a bit of a newb to the Linux side of both Codelite (CL) (13.0.5) & wxWidgets (3.1.2 manually built from Github code without issues)), I have installed both of these on a Mint box ( Mint Cinnamon 19.2)
The project I want to port from Windows, where it all compiles and runs, uses a wxRichTextCtrl window and the Codelite linker complains about the undefined reference.
As it is, I have no real clue where or how I would fix this, being used to multi-lib static linking under Windows
I can find my wxWidgets libraries and am prepared to give dynamic liking a try as some other basic wxWidgets app seem to compile and run, mainly the CL demo app.

Hi,
wxWidgets (3.1.2 manually built from Github code without issues)
What was your configure line? In particular, a static or dynamic build?
Codelite linker complains about the undefined reference
(Nitpick: The Mint linker. CL creates a makefile that calls the compiler and linker, it doesn't actually build the program itself.)

What does your Project Settings: Linker > Linker Options field contain? For a dynamic-linking wx it should be something like:
$(shell wx-config --libs std,richtext)

Regards,

David

Thank you.
That last part about "$(shell wx-config --libs std,richtext)" did the trick.

As for the static vs dynamic linking, I will have to explore down the road because for now I have only compiled the dynamic libs of wxWidgets.
If you can point me in the right direction on what I need to know to get static linking set up, I'll be very grateful. I understand Linux apps are typically set to use dynamic linking but as I am just as unfamiliar with packaging the app and all its dependencies so that I can give the app to someone else without too much fuss, I prefer to look at a statically linked package.

Just make a wx build doing, in the extracted wx source, something like:
mkdir disable-shared && cd disable-shared
../configure --disable-shared <--enable-debug --with-gtk=$(number) --whatever>
make -j`nproc`

I almost always add --prefix=$(pwd) to the configure line for such builds. That means they don't need to be 'make installed', you can use them where they are; you'd point to that dir's wx-config in your makefile or CL Compile and Linker settings. So your new Linker settings would be similar to:
$(shell /full/path/to/disable-shared/wx-config --libs std,richtext)

Thank you.
I'll give this a try, once I get the dynamic version working well enough;
still have some porting issues to resolve.

Now that I have the dynamically linked version working as well as I need for the time being, I have started to try and implement the statically linked version. For the record & in case I need to come back to this:

I have executed the commands:
mkdir disable-shared && cd disable-shared
../configure --disable-shared --enable-debug --with-gtk=2 --prefix=$(pwd)
make -j4
and as far as I can tell, that all worked

Next I have changed the c++ compiler options to: $(shell ~/wxWidgets-3.1.2/disable-shared/wx-config --cflags)
and the linker options:$(shell ~/wxWidgets-3.1.2/disable-shared/wx-config --libs )
with the Libraries:
libwx_baseu-3.1
libwx_baseu_net-3.1
libwx_baseu_xml-3.1
libwx_gtk2u_adv-3.1
libwx_gtk2u_aui-3.1
libwx_gtk2u_core-3.1
libwx_gtk2u_gl-3.1
libwx_gtk2u_html-3.1
libwx_gtk2u_propgrid-3.1
libwx_gtk2u_qa-3.1
libwx_gtk2u_ribbon-3.1
libwx_gtk2u_richtext-3.1
libwx_gtk2u_stc-3.1
libwx_gtk2u_xrc-3.1
libwxjpeg-3.1
libwxregexu-3.1
libwxscintilla-3.1.a
curl.a

All compiles, links and executes and runs as well as the dynamically linked version
Big thank you to DavidGH
