Several libraries define identical symbols which prevent static linking.
I need to statically link my programs so that they can be easily used on machines where Stratego/XT isn’t installed.

In order to generated statically linked programs, I ran ./configure –disable-shared and then make LDFLAGS=‘-all-static’ (which is a libtool flag that tells libtool to not use shared libs at all).

STR-673, martin:
I have investigated this issue a bit and found the problem. It is related to STR-672 (multiple external definitions warnings in strc)

1) Library foo defines a signature.

Consequence: libfoo contains the signature and external definitions for (some?) for congruences over this signature.

2) Library bar imports libfoo

Consequence: libbar contains the signature (again) and no external definitions for the congruences

3) Library fred imports libbar

Consequence: libfred will implement the congruences and define the external definitions again.

So what’s wrong? I think that ‘external’ signatures (defined in libfoo) should not be exported again in the newly generated libbar, similar to the recent change that external definitions of imported libraries are not exported.

As a temporary workaround, libraries can import all the indirect dependencies, to make the congruences that were already defined visible. I will commit this for the stratego-libraries.
