Я пытаюсь скомпилировать некоторый код C ++ (включая функции C ++ 11) на OS X 10.8, используя компилятор clang ++. У меня есть make-файл, который генерирует объектные файлы ОК, затем по команде:

clang++  -o Analysis.so -shared DataFile.o CR39DataFile.o

Я получаю тонны ошибок о символах, не найденных для архитектуры x86_64. Код отлично работает в системе * nix, использующей g ++ и соответствующим образом изменяющей флаги компилятора для поддержки C ++ 11. Для компиляции * .o я делаю это так:

clang++ -c -Wall -std=c++11 -stdlib=libc++ -I../src ../src/DataFile.cc

Редактировать: вывод команды связывания:

clang++  -o Analysis.so -shared DataFile.o CR39DataFile.o
