-5.4 Build with statically built dependency
-
- The build scripts in curl (autotools, cmake and others) are primarily done to
- work with shared/dynamic third party dependencies. When linking with shared
- libraries, the dependency "chain" is handled automatically by the library
- loader - on all modern systems.
-
- If you instead link with a static library, we need to provide all the
- dependency libraries already at the link command line.
-
- Figuring out all the dependency libraries for a given library is hard, as it
- might also involve figuring out the dependencies of the dependencies and they
- may vary between platforms and even change between versions.
-
- When using static dependencies, the build scripts will mostly assume that
- you, the user, will provide all the necessary additional dependency libraries
- as additional arguments in the build. With configure, by setting LIBS/LDFLAGS
- on the command line.
-
- We welcome help to improve curl's ability to link with static libraries, but
- it is likely a task that we can never fully support.
