tôi cố gắng để xây dựng ứng dụng của tôi với CMake trên Mac OS X, tôi nhận được lỗi sau:"ld: Tùy chọn unknown: -soname" trên OS X
Linking CXX shared library libsml.so
ld: unknown option: -soname
collect2: ld returned 1 exit status
make[2]: *** [libsml.so] Error 1
make[1]: *** [CMakeFiles/sml.dir/all] Error 2
make: *** [all] Error 2
Đây là kỳ lạ, như Mac có .dylib mở rộng thay vì .so.
Có CMakeLists.txt tôi:

Không có lỗi trên Linux.
quá trình xây dựng:
cmake -D BuildType=Debug -D LibraryType=shared .
make
tôi thấy, mà lệnh không chính xác tạo ra trong CMakeFiles/sml.dir/link.txt. Nhưng tại sao, vì mục tiêu của CMake là đa nền tảng ..
Cách khắc phục?
Tôi không biết CMake, nhưng đây là gợi ý: hãy thử xem các dự án dựa trên CMake được xây dựng trong MacPorts hoặc Fink vì chúng vá chúng để xây dựng trên Mac OS X. –
