cmake on mac fails with (missing: wxWidgets_LIBRARIES)

[futuretrash]

I'm trying to use wxWidgets with cmake on mac so I had to build it from sources.

Code: Select all

git clone https://github.com/wxWidgets/wxWidgets
cd wxWidgets
mkdir build-cocoa-osx
cd build-cocoa-osx
../configure --enable-debug
make -j 8
make install

The installation was successful and I was able to build the samples and demos as well.

Code: Select all

./wx-config --cxxflags
  -I/..../wxWidgets/build-cocoa-debug/lib/wx/include/osx_cocoa-unicode-3.1 -I/..../wxWidgets/include -D_FILE_OFFSET_BITS=64 -D__WXMAC__ -D__WXOSX__ -D__WXOSX_COCOA__

wx-config for libs

Code: Select all

./wx-config --libs
-L/..../wxWidgets/build-cocoa-debug/lib   -framework IOKit -framework Carbon -framework Cocoa -framework AudioToolbox -framework System -framework OpenGL -lwx_osx_cocoau_xrc-3.1 -lwx_osx_cocoau_html-3.1 -lwx_osx_cocoau_qa-3.1 -lwx_osx_cocoau_core-3.1 -lwx_baseu_xml-3.1 -lwx_baseu_net-3.1 -lwx_baseu-3.1 

In the CMakeLists.txt I added

Code: Select all

find_package(wxWidgets REQUIRED core base HINT ${wxWidgets_ROOT_DIR})
message(STATUS "wxWidgets library:")

But when I run cmake on my project with the following command

Code: Select all

cmake -G "Unix Makefiles" -DwxWidgets_ROOT_DIR=/..../wxWidgets/build-cocoa-osx -DwxWidgets_LIB_DIR=/..../wxWidgets/build-cocoa-osx/lib . -B build

CMake Error at /usr/local/Cellar/cmake/3.17.3/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:164 (message):

* I used /..../ as simplification for the users folder structure.

I don't work under OSX and i know even less about cmake, but are you sure this is right?

Code: Select all

-DwxWidgets_ROOT_DIR=/..../wxWidgets/build-cocoa-osx

Try without the /build-cocoa-osx/

[futuretrash]

@doublemax: The /..../ is only a simplification of the users folder structure. Or do you pertain on the / in the end?

No, i meant the "build-cocoa-osx" part. My suggestion was to try just:

Code: Select all

-DwxWidgets_ROOT_DIR=/..../wxWidgets/

[futuretrash]

I tried multiple variants for wxWidgets_ROOT:

Code: Select all

-DwxWidgets_ROOT_DIR=/..../wxWidgets/build-cocoa-debug/lib
-DwxWidgets_ROOT_DIR=/..../wxWidgets/build-cocoa-debug
-DwxWidgets_ROOT_DIR=/..../wxWidgets

I tried the same diretories for wxWidgets_LIB_DIR as well.

For better understanding, I published a sample project with github actions to build wxWidgets for osx:

Hi,
Why not use a standard way of building under OSX - install and use Xcode?

Thank you.

[futuretrash]

Building with xcode would force me to one platform, I don't need to use wxWidgets nor c++ for a single platform solution.
One of the biggest features of wxWidgets should be multiplatform support

wxWidgets is a C++ library that lets developers create applications for Windows, macOS, Linux and other platforms with a single code base.

Also it should be included in an already existing project based on cmake. So It has to be build with cmake.

[ONEEYEMAN]

Hi,
While wxWidgets is a cross-platform C++ library, you will still suppose to build the library itself and then your code natively on the platform in question.
That's how C++ works comparing to "JAVA".
Are you trying to make the code to compile by the user of the software you're developing?
Or you (and your company) will distribute the binaries?

Thank you.

[futuretrash]

Distribute the app as binary either with an installer and shared libs or as linked against static libs.
Right now I'm hesitating to use wxwidgets since these initial compile issues

[doublemax]

Cmake support in wxWidgets is relatively new and - as far as i can tell - rarely used.

Try posting on the wx-users group where you can reach the core developers. This is a user forum.

I successfully build the samples using CLion and CMake. You can find my steps here:
