i use the libreoffice branch distro/collabora/cp-6.4 and my computer is linux arm64 ubuntu 20.04 and my autogen.input CC=/usr/bin/clang CXX=/usr/bin/clang++ –with-jdk-home=/usr/lib/jvm/java-11-openjdk-arm64 –with-android-ndk=/home/$USER/Android/Sdk/ndk/android-ndk-r20b –with-android-sdk=/home/$USER/Android/Sdk –with-distro=CPAndroid –enable-sal-log i add CC=/usr/bin/clang CXX=/usr/bin/clang++ If I don’t add when run ./autogen.sh will report an error but when i run make still error, i also try use ndk21, ndk23 all error too error message here: pixman-glyph.c:401:16: warning: unknown attribute ‘ **force\_align\_arg\_pointer** ’ ignored [-Wunknown-attributes] **attribute** (( **force\_align\_arg\_pointer** )) ^ pixman-glyph.c:643:16: warning: unknown attribute ‘ **force\_align\_arg\_pointer** ’ ignored [-Wunknown-attributes] **attribute** (( **force\_align\_arg\_pointer** )) ^ 2 warnings generated.
