 Cmake kann Java beim Erstellen von OpenCv nicht erkennen

Post by Anonymous »

Ich versuche, OpenCv auf Khadas Vim2 zu erstellen, das über ein vorinstalliertes Ubuntu Mate mit einer arm 64-Bit-basierten CPU-Architektur verfügt, unter Verwendung von CMake. Allerdings erkennt CMake Java nicht (

Code: Select all

where i already have both oracle-jdk-1.8 and openjdk-1.8
). Ich habe versucht, Apache Ant neu zu installieren und JAVA_HOME und ANT_HOME in PATH zu exportieren über:

Code: Select all

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-arm64
export PATH=$JAVA_HOME/bin:$PATH
export ANT_HOME=/usr/local/ant
export PATH=$ANT_HOME/bin:$PATH
Ich habe auch versucht, die GCC- und G++-Compiler in der Toolchain-Datei wie folgt festzulegen:

Code: Select all

set( CMAKE_SYSTEM_PROCESSOR arm )
set( CMAKE_C_COMPILER arm-linux-gnueabi-gcc )

endif()

toolchain_save_config()
aber nach dem Ausführen des cmake-Befehls immer noch die folgende Ausgabe:

Befehl:
