[qt][python][custom build] qt-ida build

[DramaDesu]

Hello!
I have a special version of qt to build. It has been patched to use with ida pro sdk.
I'm trying to write my own portfile, every thing is alright expect run cmd with python script via port file:

vcpkg_extract_source_archive(
    SOURCE_PATH
    ARCHIVE "${CMAKE_CURRENT_LIST_DIR}/qt-5.15.2-full-IDA83.tar.bz2"
)

set(DEV_CMD "${VS_PATH}/Common7/Tools/VsDevCmd.bat")

file(WRITE "${BUILD_WORK_DIR}/build/build.bat"
    "@echo off\n"
    "call \"${DEV_CMD}\"\n"
    "python build.py -j 16 -v\n")

execute_process(
    COMMAND cmd /c build.bat
    WORKING_DIRECTORY "${BUILD_WORK_DIR}/build"
    RESULT_VARIABLE BUILD_RESULT
)

I'm wondering if there are some restrictions in vcpkg_installed folder, in case I move sources with script, for example to disk C, it works, but in this case it doesn't. Could you explain me how to avoid access restriction or some workaround. To clarify: script runs, but stops somehow with error 2. (seems like disk restrictions)

Vcpkg on windows clears parent environment so if you need to run python you should aquire it using vcpkg_find_acquire_program(PYTHON3).

I do:

execute_process(
    COMMAND cmd /c "echo %ProgramFiles(x86)%"
    OUTPUT_VARIABLE PROGRAMFILES_X86
    OUTPUT_STRIP_TRAILING_WHITESPACE
)

set(VSWHERE_EXE "${PROGRAMFILES_X86}/Microsoft Visual Studio/Installer/vswhere.exe")

execute_process(
    COMMAND "${VSWHERE_EXE}" -latest -products * -property installationPath
    OUTPUT_VARIABLE VS_PATH
    OUTPUT_STRIP_TRAILING_WHITESPACE
)

file(TO_CMAKE_PATH "${VS_PATH}" VS_PATH)
message(STATUS "VS_PATH: ${VS_PATH}")

set(DEV_CMD "${VS_PATH}/Common7/Tools/VsDevCmd.bat")
message(STATUS "DEV_CMD: ${DEV_CMD}")

vcpkg_extract_source_archive(
    SOURCE_PATH
    ARCHIVE "${CMAKE_CURRENT_LIST_DIR}/qt-5.15.2-full-IDA83.tar.bz2"
)

file(RENAME "${SOURCE_PATH}/build/build.py" "${SOURCE_PATH}/build/build_orig.py")
file(COPY "${CMAKE_CURRENT_LIST_DIR}/build.py" DESTINATION "${SOURCE_PATH}/build")

vcpkg_find_acquire_program(PYTHON3)
get_filename_component(PYTHON_PATH "${PYTHON3}" DIRECTORY)
vcpkg_add_to_path("${PYTHON_PATH}")

if(VCPKG_TARGET_IS_WINDOWS)
    vcpkg_find_acquire_program(PERL)
    get_filename_component(PERL_PATH "${PERL}" DIRECTORY)
    vcpkg_add_to_path("${PERL_PATH}")

    vcpkg_find_acquire_program(JOM)
    get_filename_component(JOM_PATH "${JOM}" DIRECTORY)
    vcpkg_add_to_path("${JOM_PATH}")
endif()

set(QT_INSTALL_PREFIX "${CURRENT_BUILDTREES_DIR}/qt-install")

set(BUILD_WORK_DIR "${CURRENT_BUILDTREES_DIR}/qt-ida-work")
file(REMOVE_RECURSE "${BUILD_WORK_DIR}")
file(MAKE_DIRECTORY "${BUILD_WORK_DIR}")

file(COPY "${SOURCE_PATH}/." DESTINATION "${BUILD_WORK_DIR}")

file(WRITE "${BUILD_WORK_DIR}/build/build.bat"
    "@echo off\n"
    "call \"${DEV_CMD}\"\n"
    "python build.py -j 16 -v\n")

execute_process(
    COMMAND cmd /c build.bat
    WORKING_DIRECTORY "${BUILD_WORK_DIR}/build"
    RESULT_VARIABLE BUILD_RESULT
)

message(FATAL_ERROR "Build result: ${BUILD_RESULT}")

I'm wondering if there are some restrictions in vcpkg installed folder.

[DramaDesu]

if I move unpacked archive to another folder (for example to disk C), everything is alright

[DramaDesu]

message(FATAL_ERROR "Build result: ${BUILD_RESULT}")
That's for test to do not cache package

[DramaDesu]

It works if it unpacks the archive to another disk, or out of vcpkg folder (either use .bat file manually or via execute_process)
But it doen't if it runs the same in CURRENT_BUILDTREES_DIR

[DramaDesu]

It seems like some restrictions in user call functions, or etc, it seems like qt script requires some sys call or admin mode

[Osyotr]

It's really hard to tell anything without any logs.

I think, something with configuration, or I forget to add includes somewhere

The path is 293 characters long. It's too long for Windows, you should use -x-buildtrees-root or move your vcpkg installation.

Awesome, I will try, I think it will be fixed
