Force static linking of library linked to Xcode target?
提问by Barry Wark
My Xcode target links against hdf5 library (using the Link Binary with Libraries build phase). libhdf5 is installed using MacPorts, thus /opt/local/lib contains both the dynamic (.dylib) and static (.a) versions of the library.
我的 Xcode 目标链接到 hdf5 库（使用链接二进制与库构建阶段）。libhdf5 是使用 MacPorts 安装的，因此 /opt/local/lib 包含库的动态 (.dylib) 和静态 (.a) 版本。
The text output from the build shows that there is, as expected, a -lhdf5in the linking step of the build. gcc seems to take the dynamic linked library over the static, however. Is there any way to force gcc (via a compiler switch or via Xcode) to statically link with libhdf5.a?
构建的文本输出显示，正如预期的那样，-lhdf5构建的链接步骤中有 a。然而，gcc 似乎将动态链接库置于静态之上。有没有办法强制 gcc（通过编译器开关或通过 Xcode）与 libhdf5.a 静态链接？
The only solution I've found is to copy libhdf5.a to the project (or other) directory and link against that copy, thus avoiding having dynamic and static versions in the same location.
我找到的唯一解决方案是将 libhdf5.a 复制到项目（或其他）目录并链接到该副本，从而避免在同一位置具有动态和静态版本。

In reaction to your comment on Eduard Wirch' answer: you can also control static linking for this one library only, if you replace -lhdf5 by -l/full/path/to/libhdf5.a
回应您对 Eduard Wirch 回答的评论：如果您将 -lhdf5 替换为 -l/full/path/to/libhdf5.a，您还可以仅控制该库的静态链接

Had this exact same problem and despite this being an old post, I thought I'd share what I had to do to make this work.
遇到了完全相同的问题，尽管这是一篇旧帖子，但我想我会分享我必须做的事情才能完成这项工作。
Usually you do just provide the switch '-static' to the linker however, with Xcode this causes all libs including the crt to be linked statically. I got the error:
通常，您只是向链接器提供开关“-static”，但是，对于 Xcode，这会导致包括 crt 在内的所有库都静态链接。我收到错误：
can't locate file for: -lcrt0.o
When I tried this.
当我尝试这个时。
The thing which worked for me was to replace:
对我有用的是替换：
-lmylib
with
和
/path/to/libmylib.a
/path/to/libmylib.a
Note: the -l is dropped.
注意： -l 被删除。

My case with Xcode 4.5:
我的 Xcode 4.5 案例：
When I drag and drop a static C library (a 3rd party library compiled with GNU Autotools) to project's frameworks (Project Navigator > Frameworks) the linker seems to thinks that's a dynamic library and adds -L -lflags:
当我将静态 C 库（使用 GNU Autotools 编译的第 3 方库）拖放到项目的框架 ( Project Navigator > Frameworks) 时，链接器似乎认为这是一个动态库并添加了-L -l标志：
-L/path/to/libfoodir -lfoo
The linking fails because there is no /path/to/libfoodir/libfoo.dylib.
The linker command can be seen from:
链接失败，因为没有/path/to/libfoodir/libfoo.dylib. 链接器命令可以从：
Log Navigator > select a Build log > select a Link line and expand it
The linking succeeds when I add a full path (/path/to/libfoodir/libfoo.a) to the linker settings:
当我/path/to/libfoodir/libfoo.a向链接器设置添加完整路径 ( )时，链接成功：
Targets > Build Settings (all) > Other linker flags

Use the "-static" switch for linking: GCC link options
使用“-static”开关进行链接： GCC 链接选项

Tried to add absolute lib path to Other linker flags. But that doesn't work. So I copied required *.a files (ln -s may also work) to project dir and it worked like a charm.
试图将绝对 lib 路径添加到Other linker flags. 但这不起作用。所以我将所需的 *.a 文件（ln -s 也可以工作）复制到项目目录中，它的作用就像一个魅力。
