Question

我无法将静态库链接到Mac OS X上的可执行文件。我的回购目录lib包含所有库，例如libstdc++.a，libssl.a，libz.a。

CMakeList.txt包含：

(...)
set(PROJECT_LINK_LIBS libcurl.a libz.a libssl.a libcrypto.a libstdc++.a libjson-c.a)
link_directories(lib/)
add_executable(myapp ${SOURCES})
target_link_libraries(myapp ${PROJECT_LINK_LIBS} ${CMAKE_THREAD_LIBS_INIT} ${CMAKE_DL_LIBS})

编译时我收到了一条消息（对于每个.a文件）：

ld: warning: ignoring file /Users/kuba/CLionProjects/RigService/lib/macos/libz.a, file was built for archive which is not the architecture being linked (x86_64)

和

Undefined symbols for architecture x86_64:
    "_curl_easy_cleanup", referenced from:
        HTTPConnection::request(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >, char const*) in HTTPConnection.cpp.o
    "_curl_easy_init", referenced from:
        HTTPConnection::request(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >, char const*) in HTTPConnection.cpp.o
    "_curl_easy_perform", referenced from:
        HTTPConnection::request(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >, char const*) in HTTPConnection.cpp.o
(...)

我之前在linux上编译了这个，在那里我没有任何问题我想从.o中提取所有.a个文件，并再次使用

构建一个存档文件

ar rcs libcurl.a *.o

但在此之后我遇到了同样的问题我还试图通过

建立档案

libtool -static -o libcurl.a *.o

然后我收到了一条消息：

sal:libcrypto kuba$ libtool -static -o libcrypto.a *.o
error: /Library/Developer/CommandLineTools/usr/bin/libtool: file: a_bitstr.o is not an object file (not allowed in a library)
error: /Library/Developer/CommandLineTools/usr/bin/libtool: file: a_bool.o is not an object file (not allowed in a library)
error: /Library/Developer/CommandLineTools/usr/bin/libtool: file: a_bytes.o is not an object file (not allowed in a library)
(...) // error for each .o file

这是我的问题，也许我应该从中开始，我可以在linux和mac os上编译时链接相同的.a文件吗？

您是否尝试使用为Linux构建的库？这不会起作用，你需要为macOS构建的库。

无法在Mac OS X上链接静态库
