#arm #cross-compiling #glibc
#arm #перекрестная компиляция #glibc
Вопрос:
Я пытаюсь перекрестно скомпилировать glibc 2.10.1 с помощью arm-none-linux-gnueabi-gcc 4.4.1.
Процесс шел хорошо, пока он не собрал build_dir/csu/crti.S, gcc сообщает об ошибке «duplicate .fnstart directive».
были сгенерированы initfini.s и crti.s, но я не знаю, были ли они действительными или нет.
Makefile намеревается разделить initfini.s на crti.s и crtn.s, поэтому пары .fnstart .fnend в initfini.s были разделены на crti.s и crtn.s, а затем они не были сопоставлены, что привело к жалобе gcc на директиву duplicate .fnstart .
Итак, как я могу скомпилировать crti.o и crtn.o с этой версией 4.4.1 gcc? Приветствуются любые советы.

Ответ №1:
Оба .fnstart и .fnend являются директивами LLVM, обозначающими начальную и конечную позиции функции.
Вы должны заменить их на .func и .endfunc соответственно для GCC.
