CodeLite on Kubuntu 20.04 VM

[Netzschleicher]

Hello together,

i set up a new VM with KUbuntu 20.04 LTS.
wxWidgets are kompiled with following Script:

Code: Select all

#!/bin/bash
cd /usr/share/wxWidgets-3.1.5/
mkdir gtk-build
cd gtk-build
../configure --enable-debug --disable-shared --enable-mediactrl --with-opengl
make install
ldconfig
make clean
../configure --disable-debug --disable-shared --enable-mediactrl --with-opengl
make install
ldconfig
make clean
../configure --enable-debug --enable-shared --enable-mediactrl --with-opengl
make install
ldconfig
make clean
../configure --disable-debug --enable-shared --enable-mediactrl --with-opengl
make install
ldconfig
make clean
cd ..
rm -rf gtk-build
cd /home/uwe

Now, when i compile an Application i Points to /usr/lib/x86_64-linux-gnu/wx but it should point to /usr/local/lib/wx !
Is there an Environment-Variable like 'WXCFG' to use?

Thanks very much

On Linux, wxWidgets uses the wx-config script.
If you get the wrong paths, it means that the wrong wx-config tool was used.

If I had to guess, I would say that you have 2 wx-config (at least) installed

• /usr/bin/wx-config
• /usr/local/bin/wx-config

Local builds will install under /usr/local/

What is the output of /usr/local/bin/wx-config --libs ? does it produce the output you want?
If it does, than its just a matter of setting up your PATH environment variable in your ~/.bashrc (assuming you are using bash) to include:

Code: Select all

export PATH=/usr/local/bin:$PATH

If you are build from within CodeLite, than you have 2 options:

• In the project settings, modify the $(shell wx-config --libs) and $(shell wx-config --cflags) (from the project settings -> compiler and project settings -> linker) to use full path (i.e. use /usr/local/bin/wx-config)
• Go to settings -> environment variables and add this line: PATH=/usr/local/bin:$PATH

Code: Select all

wx-config --libs

shows me the right libs.

But setting PATH=/usr/local/bin:$PATH in Bash and/or in CodeLite Environment changes nothing.
CodeLite says

/bin/make -e -f Makefile

some hint: 'wx-config --libs' on bash uwe@vm-linux-prog:~$ gives:

Code: Select all

-L/usr/local/lib -pthread   -lwx_gtk3u_xrc-3.1 -lwx_gtk3u_html-3.1 -lwx_gtk3u_qa-3.1 -lwx_gtk3u_core-3.1 -lwx_baseu_xml-3.1 -lwx_baseu_net-3.1 -lwx_baseu-3.1

but in CodeLite it refers to /usr/bin

When i compile with CMake as Build System, all good. It compiles without errors.
But with CodeLite Makefile Generator it cannot find my compiled wxWidgets.

Hi,

Warning: No config found to match: /bin/wx-config --libs --unicode=yes --static=yes
in /usr/lib/x86_64-linux-gnu/wx/config

You have a normal, dynamic-linking wx build, not a static-linking one (which is rarely used/needed on Linux). However, somewhere in your workspace configuration (probably the Linker section) you have added --disable-shared or similar. Remove that, do a clean build and it should work.

Regards,

David

You are right. I have a static an a dynamic build to switch between them. When compiling with CMake all work find and i can compile a dynamic and also a static Application.
With Codelite makefile Generator no of them compiles.
Also the Codelite makefile Generator uses /bin/wx-config which refers to System preinstalled wx3.0.
CMake refers to /usr/local/bin/wx-config which is my compiled wx3.1.

[DavidGH]

Also the Codelite makefile Generator uses /bin/wx-config which refers to System preinstalled wx3.0.

Then you need to tell it not to. The easiest way is to use the full path in the Compiler and Linker settings:

Code: Select all

-g;-O0;-Wall;$(shell /usr/local/bin/wx-config --cflags)
and
$(shell /usr/local/bin/wx-config --libs)

Thank s a lot for the Tipps.

I setup my Projects with CMake and all works fine on Linux and Windows.
