Errore di collegamento degli utensili Cmake e clang (esterno dell'albero sorgente)

Sto tentando di compilare lo RecursiveASTVisitor example of Clang utilizzando un file CMake. La costruzione del progetto va bene, tuttavia il collegamento dell'eseguibile C++ fallisce con riferimenti multipli non definiti alle librerie LLVM e Clang. Sto costruendo l'esempio al di fuori della struttura del file sorgente LLVM/Clang.Errore di collegamento degli utensili Cmake e clang (esterno dell'albero sorgente)

Ecco il mio CMakeLists.txt (sto usando FindClang.cmake and FindLLVM.cmake from this project):

    ${CMAKE_CURRENT_SOURCE_DIR}/cmake/modules

Devi collegare alla libreria LLVMOptions. Verifica se "options" è un target 'llvm_map_components_to_libnames' supportato nella tua versione LLVM, o semplicemente aggiungilo come target_link_library'. – TartanLlama

Ciao, l'opzione è supportata, ma l'aggiunta a 'llvm_map_components_to_libnames', o l'aggiunta di LLVMOption a' target_link_library' non risolve il problema di collegamento. Ancora avendo lo stesso errore di cui sopra. – Adel

L'ordine in cui i flag del linker vengono visualizzati sulla riga di comando è importante in quanto vi sono delle dipendenze tra le librerie. Prova a inserire 'LLVMOption' all'inizio di' target_link_libraries'. – TartanLlama

Ho finito per utilizzare la riscrittura di CMakeLists.txt basata su this particular file.

usa meglio 'llvm-config --src-root' per $ LLVM_PATH –

Grazie Hongxu, è molto utile. – Adel
