Force linking a static library into a shared one with Libtool

Question

I have a library (libfoo) that is compiled using libtool into two objects: libfoo.a and libfoo.so.

I have to create, using libtool

Answer 1

The standard way would be to build libfoo with --disable-shared. Whether to link statically or dynamically is a decision for the user to make, so there's really no way to force it as a package maintainer, but you could set the configury of libbar to fail if libfoo.so is present (I'm not sure of a clean way to do that, and believe it would be a bad idea since it really is a choice for the user.) I think the best bet is to have the user build libfoo with --disable-shared, but you can force that choice by specifying static libraries only in libfoo/configure.ac:

LT_INIT([disable-shared])

Note that if you do that, it will not be possible to build libfoo as a shared library. Perhaps that is what you want.
