Greetings,

I am getting a “make check” linking error ( e.g. ./.libs/library.so: undefined reference to ‘function implemented in another library within the same makefile). Libtool builds everything just fine using bin_, but when copying and pasting the _CFLAGS, _LDADD, etc., renaming to check_ and rebuilding via make check, I get the error.

Note: the referenced libraries are all Libtool .la libraries generated within a large project Makefile. Again, all libraries are building and executing just fine. The only issue is when I attempt to use make check.

Finally, if I comment out the unit test code (leaving essentially a bare bones empty unit test) and remove the LDADD references to the Libtool intermediate libraries and make check works fine (it builds, runs, and shows the Pass/Fail report).

I have done everything I can think of to make this work but I have gotten nowhere. So, I’m guessing this is a bug somewhere.


Thanks,

Michael Cress

In order to help you, It works better if you show us code. :-)

Ideally you would provide a minimal example to let others reproduce the
bug.  You can use “${prefix}/share/doc/automake/amhello-1.0.tar.gz”
example as a basis and add what doesn't work for you.

Thanks.
