Building wxLua in WSL Ubuntu - wxWidgets libraries not found...

[imfatant]

I'm trying to build wxLua (obtained from Github) on WSL Ubuntu using the method described here: https://github.com/pkulchenko/wxlua/blob/master/wxLua/docs/install.md#C4.6

The problem is that despite wxWidgets being installed, and working, CMake is not finding it.

wx-config IS found by CMake (and I checked that it works manually), but CMake still says it can't find wxWidgets.

For reference, here is how I installed wxWidgets:

git clone https://github.com/wxWidgets/wxWidgets
git submodule update --init --recursive
sudo apt-get install build-essential libgtk-3-dev
mkdir buildgtk
cd buildgtk
../configure --with-gtk
make
sudo make install
sudo ldconfig

The libraries are where they should be (I believe):

As I've mentioned, I have checked that /usr/local/bin/wx-config exists and works. Typing wx-config --libs all comes back with the libraries:

-L/usr/local/lib -pthread -lwx_gtk3u_xrc-3.1 -lwx_gtk3u_stc-3.1 -lwx_gtk3u_richtext-3.1 -lwx_gtk3u_ribbon-3.1 -lwx_gtk3u_propgrid-3.1 -lwx_gtk3u_aui-3.1 -lwx_gtk3u_gl-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

I've tried adding a new entry in cmake-gui: wxWidgets_LIBRARY_DIRS /usr/local/lib

I've also tried adding wxWidgets_CONFIG_EXECUTABLE /usr/local/bin/wx-config

Can you help?

I'm not sure what's going on, but will try to reproduce this when I get a chance. What version Ubuntu are you using and what version of CMake are you running?

It seems to be failing on VERIFY_WXWIDGETS_COMPONENTS (this is why you get the list of all missing components), although this doesn't seem to be the main issue and the method has the following comment, so it's possible that it's a sort of expected result:

    # Search through the list of components to see what we were able to find.
    # CMake's find_package for wxWidgets fails on missing components and for
    # some reason CMake's find function gives no indication as to why it failed
    # which makes it difficult, if not impossible, to ever 'find' wxWidgets.

    # In Linux using wx-config the WX_{base/core/etc} vars are not set.
    # Mark all libs as not found.

The main failure seems to be in the find_package call that comes with Cmake: find_package( wxWidgets COMPONENTS ${wxWidgets_COMPONENTS}).

Actually, I think I know what may be going on; you run ../configure --with-gtk, but expect gtk3 to be used. Try running ../configure --with-gtk=3 instead.

[imfatant]

Hi,

Thanks for the reply. I tried rebuilding wxWidgets using ../configure --with-gtk=3 but it seems to have made no difference. Still the same errors.

This is Ubuntu 20.04.2 LTS and CMake version 3.16.3.

[pkulchenko]

Interesting. Can you include the output from wx-config after you build wxwidgets with that command?

[imfatant]

Here's the output of wx-config now: wx-config: Available libraries in this build are: xrc stc richtext ribbon propgrid aui gl html qa adv core xml net base

wx-config --libs all: -L/usr/local/lib -pthread -lwx_gtk3u_xrc-3.1 -lwx_gtk3u_stc-3.1 -lwx_gtk3u_richtext-3.1 -lwx_gtk3u_ribbon-3.1 -lwx_gtk3u_propgrid-3.1 -lwx_gtk3u_aui-3.1 -lwx_gtk3u_gl-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

@pkulchenko

I have got a little further.

One problem appears to have been because of missing dependencies for wxWidgets. So, I rebuilt it after doing:

sudo apt-get install build-essential libreadline-dev
sudo apt-get install libgtk-3-dev libwxgtk-webview3.0-gtk3-dev libwxgtk-media3.0-gtk3-dev
sudo apt-get install libgstreamer-gl1.0-0 libgstreamer-plugins-base1.0-0 libgstreamer-plugins-base1.0-dev libgstreamer-plugins-good1.0-0 libgstreamer-plugins-good1.0-dev libgstreamer1.0-0 libgstreamer1.0-0-dbg libgstreamer1.0-dev
sudo apt-get install libwebkit2gtk-4.0-dev

Next, is a small issue with CMake and wxLua. CMakewxAppLib.cmake doesn't handle parsing portname for gtk3, but I managed to fix this by changing the following section:

# wxWidgets GTK1-3 build using configure
    if ("${wxWidgets_PORTNAME}" STREQUAL "")
        string(REGEX MATCH "wx_(gtk[1-3]?)(univ)?(u)?(d)?_core-([0-9].[0-9])" _match_gtk "${wxWidgets_LIBRARIES}")

        if (NOT "${_match_gtk}" STREQUAL "")
            set(wxWidgets_PORTNAME    "${CMAKE_MATCH_1}" )
            set(wxWidgets_UNIVNAME    "${CMAKE_MATCH_2}" )
            set(wxWidgets_UNICODEFLAG "${CMAKE_MATCH_3}" )
            set(wxWidgets_DEBUGFLAG   "${CMAKE_MATCH_4}" )
            #set(wxWidgets_LIB_VERSION "${CMAKE_MATCH_5}" )
        endif()
    endif()

Now CMake builds... almost! Here's CMake's output:

The odd thing is that the wxWidgets webview and propgrid libraries DO exist, so I don't know what's going on.

EDIT: I edited CMakeLists.txt so that propgrid and webview are specified. wxLua now almost builds:

@imfatant, you may need to add -DCMAKE_CXX_FLAGS="-DwxLUA_USE_wxTranslations=0" option to cmake to fix undefined reference to 'wxPluralFormsCalculatorPtr::~wxPluralFormsCalculatorPtr()' error. See the discussion in #80.

-- WARNING: Specified wxLuaBinding lib 'webview' in variable wxLuaBind_COMPONENTS is missing from wxWidgets_COMPONENTS so it will not be compiled. -- WARNING: Specified wxLuaBinding lib 'propgrid' in variable wxLuaBind_COMPONENTS is missing from wxWidgets_COMPONENTS so it will not be compiled.

I do see those warning too and they appear to be misleading/harmless.

Can you include a full diff with all your changes?

[imfatant]

Good. It builds fine now. Many thanks for your help.

My recipe:

git clone https://github.com/pkulchenko/wxlua
cd wxlua
cd wxLua
mkdir test
cd test
cmake -DCMAKE_CXX_FLAGS="-DwxLUA_USE_wxTranslations=0" ..  #  do this twice!
make -j8
sudo make install

Is this diff what you require?

Thank you for the diff! I pushed an update that incorporates these changes.
