Linker Errors

Error: “undefined reference to `CreateZoomVideoSDKObj’”

Cause: Not linking libvideosdk.so

Solution:

link_directories(${CMAKE_SOURCE_DIR}/lib/zoom_video_sdk)
target_link_libraries(${PROJECT_NAME} videosdk)

Error: Missing Qt symbols

Solution: Link Qt5 libraries:

target_link_libraries(${PROJECT_NAME}
    videosdk
    Qt5Core Qt5Gui Qt5Network Qt5Qml Qt5Quick
)

Header Include Errors

Error: “zoom_video_sdk_api.h: No such file or directory”

Solution:

include_directories(
    ${CMAKE_SOURCE_DIR}/include
    ${CMAKE_SOURCE_DIR}/include/zoom_video_sdk
)

Error: “helpers/zoom_video_sdk_*.h: No such file”

Solution: Include both paths:

include_directories(
    ${CMAKE_SOURCE_DIR}/include
    ${CMAKE_SOURCE_DIR}/include/zoom_video_sdk  # For helpers/ relative includes
)

Runtime Errors

Error: “libvideosdk.so: cannot open shared object file”

Solution:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/lib/zoom_video_sdk

Or set RPATH:

set_target_properties(${PROJECT_NAME} PROPERTIES
    BUILD_RPATH "${CMAKE_SOURCE_DIR}/lib/zoom_video_sdk"
    INSTALL_RPATH "${CMAKE_SOURCE_DIR}/lib/zoom_video_sdk"
)

Compiler Errors

Error: “ISO C++17 does not allow dynamic exception specifications”

Solution: SDK requires C++17:

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

Error: “pure virtual method called”

Cause: Missing IZoomVideoSDKDelegate method implementations.

Solution: Implement ALL delegate methods (even empty stubs).
