Bonjour

J'essai de crosscompiler https://github.com/bramp/libcec-daemon pour Android 9 x86_64.

Mais j'ai des erreurs de linker. Pouvez-vous m'aider ?

Cordialement,

Ayuzerak

Toute la partie de ton CMakeLists qui hardcode les propriétés de targets IMPORTED est vraiment suspicieuse. Déjà de une on évite de faire ce genre de chose, de deux tu as déjà un find_package() de Boost donc utilise les targets définies par FindBoost, de trois car tu pointes vers des .so qui sont dans x86_64-linux-gnu donc pas du tout compilés pour Android.

J'ai recompilé les libs boost 1.83.0 pour Android mais j'ai les mêmes erreurs. Je regarde pour Liblog4cplus.

J'ai pu compiler le programme mais maintenant j'ai l'erreur Cannot link executable liblog4cplus-2.1.so.9 not found. Il est dans /system/lib . Une idée ?
