Can somebody help me with emcmake error finding FindQt5.cmake

qwerty007 · wrote on 16 Sept 2024, 23:21

I am trying to build project on Ubuntu with this command:

emcmake cmake .. -DCMAKE_PREFIX_PATH=/home/oleksiy/Qt/5.15.2/wasm_32/

and get this error

CMake Error at CMakeLists.txt:16 (find_package):
  By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5" with any of
  the following names:

    Qt5Config.cmake
    qt5-config.cmake

  Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.

i checked in Qt5 folder for Qt5Config.cmake file - it's exist :/
Now i don't know what to do.

Changed -DCMAKE_PREFIX_PATH few times, checked using chatGTP version of Qt, Cmake and Emscripten for comparability, reinstalled Emscripten, added this to cmake file:

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "/home/oleksiy/Qt/5.15.2/wasm_32/lib/cmake/Qt5/")

That's the output when i've enabled verbose

I even build qt from source.
i've added --debug-find flag to cmake comand, the output:

well now added full path all needed modules in cmake command:

all you have to do is call qtpaths (found in wasm_32/bin/qtpaths) BEFORE you call emcmake

P.S.
This is TERRIBLE practice! let CMake set those variables, don't override them

set(CMAKE_C_COMPILER "emcc")
set(CMAKE_CXX_COMPILER "em++")
set(CMAKE_PREFIX_PATH "/home/oleksiy/InstalledLibraries/Qt_5.15.2_wasm-emscripten_debug")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -s FETCH")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -s MODULARIZE=1")

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -s EXPORTED_FUNCTIONS=\"['_main', '_embind_register_function', '_emval_as', '_emval_call', '_emval_call_method', '_emval_call_void_method', '_emval_decref', '_emval_equals', '_emval_get_global', '_emval_get_method_caller', '_emval_get_module_property', '_emval_get_property', '_emval_incref', '_emval_is_string', '_emval_new', '_emval_new_cstring', '_emval_new_object', '_emval_run_destructors', '_emval_set_property', '_emval_take_value', '_getentropy']\"")

@VRonin what if got only qtpaths.js?
If you mean run /home/oleksiy/Qt/5.15.2/wasm_32/bin/qtpaths.js i've got this error

RuntimeError: abort(RuntimeError: abort(RuntimeError: abort(Error: ENOENT: no such file or directory, open '/home/oleksiy/Qt/5.15.2/wasm_32/bin/qtpaths.wasm'). Build with -s ASSERTIONS=1 for more info.). Build with -s ASSERTIONS=1 for more info.). Build with -s ASSERTIONS=1 for more info.

P.s. i tried to fix build using chatgtpt and he give me this recommendations?
