GNU Autoconf, Automake, and Libtool

9.4.2. Using Convenience Libraries

To rebuild 'libtrim' as a convenience library (see Section 9.2.4, "Creating Convenience Libraries" ), use the following commands:

$ rm hello *.la

$ ls
hello.c   hello.lo   hello.o   main.c   trim.c   trim.lo   trim.o

$ libtool gcc -o libtrim.la trim.lo
rm -fr .libs/libtrim.la .libs/libtrim.* .libs/libtrim.*
ar cru .libs/libtrim.al trim.lo
ranlib .libs/libtrim.al
creating libtrim.la
(cd .libs && rm -f libtrim.la && ln -s ../libtrim.la libtrim.la)

Then, rebuild 'libhello', with an interlibrary dependency on 'libtrim', like this:

 $ libtool gcc -rpath `pwd`/_inst -o libhello.la hello.lo libtrim.la rm -fr .libs/libhello.la .libs/libhello.* .libs/libhello.* *** Warning: inter-library dependencies are not known to be supported. ...
