Exception in thread "main" eta.runtime.exception.EtaException: WrapPCRE.hsc was not compiled against pcre library with HAVE_PCRE_H defined about eta HOT 2 OPEN

Maybe it is using a version of regex-pcre-builtin that is not patched to work with eta. The patched version is regex-pcre-builtin-0.94.4.8.8.35
You can try to make the build use that version of the library adding a cabal.project like:

packages: .

constraints: bifunctors == 5.5.3,
             regex-pcre-builtin == 0.94.4.8.8.35

or alternatively run etlas build --constraint="bifunctors==5.5.3" --constraint="regex-pcre-builtin == 0.94.4.8.8.35"

I've just tested that the library can be built with those constraints, downloading it with etlas update && etlas get duckling-0.1.6.1

from eta.

Thank you for your answer. I can build it successfully, but I can't run the tests. When I excute etlas run duckling-test, it raise the exception described above.
