“ld:未知选项:-soname”在 OS X 上
我尝试在 Mac OS X 上使用 CMake 构建应用程序,但收到以下错误:
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
这很奇怪,因为 Mac 的扩展名为 .dylib 而不是 .so。
这是我的 CMakeLists.txt:

Linux 上没有错误。
构建过程:
cmake -D BuildType=Debug -D LibraryType=shared .
make
我发现,在 CMakeFiles/sml.dir/link.txt
中生成了错误的命令。但是为什么,因为 CMake 的目标是跨平台..
如何解决它?
I try to build my app with CMake on Mac OS X, I get the following error:

This is strange, as Mac has .dylib extension instead of .so.

There was no error on Linux.
Build process:
cmake -D BuildType=Debug -D LibraryType=shared .
make
I found, that incorrect command generate in CMakeFiles/sml.dir/link.txt
. But why, as the goal of CMake is cross-platforming..
How to fix it?

我在 OS X 上遇到了类似的问题,我使用
install_name
开关而不是soname
解决了这个问题。I had a similar issue on OS X which I resolved using the the
install_name
switch instead ofsoname
.您解决了您的问题,但我想将此作为未来访问者的参考,因为在 OS X 上创建动态库还有更多内容。另外,请参阅 在 Apple 开发者页面中创建动态库 。
OS X 不使用 libcoolstuff.so.XYZ 约定。相反,OS X 使用约定
libcoolstuff.X.dylib
。然后,要将XYZ
嵌入到库中,请使用-install_name
、-current_version
和-compatibility_version
。我不知道 Cmake,但这是它在 Make 下的样子。构建
libcoolstuff
1.0.6 的方法将如下所示:并且您的
make install
规则将如下所示:在
otool
下,它如下所示:最后,您将按预期使用它:
You cleared your problem, but I wanted to provide this as a reference for future visitors because there's a bit more to creating a dynamic library on OS X. Also, see Creating Dynamic Libraries in the Apple Developer pages.
OS X does not use the convention
libcoolstuff.so.X.Y.Z
. Instead, OS X uses the conventionlibcoolstuff.X.dylib
. Then, to embedX.Y.Z
into the library, use-install_name
,-current_version
and-compatibility_version
.I don't know Cmake, but here's how it looks under Make. Your recipe to build the
libcoolstuff
1.0.6 will look like:And your
make install
rule would look like:Under
otool
, it looks like:Finally, you would use it as expected:
好的,我找到问题所在了。在构建之前,您必须删除所有 CMake 临时文件夹和文件,例如
CMakeFiles
、CMakeCache.txt
、Makefile
。就我而言,问题是我在 Linux 上构建了该项目并且没有删除这些文件......这就是为什么有 .so 扩展名......
OK, I found where problem was. Before build, you have to remove all CMake temp folders and files, e.g.
CMakeFiles
,CMakeCache.txt
,Makefile
. As in my case, issue was that I built that project onLinux
and didn't delete these files...That's why there's .so extension...
我自己也有这个问题。对我来说解决这个问题的方法是删除逗号并将
-soname
替换为-install_name
Had a problem with this myself. What fixed it for me was removing the commas and replacing
-soname
with-install_name
