curiously "make all"
didnt make libmemenv.a, i had to
>make libleveldb.a libmemenv.a
but... still same error

Ah, yeah, I should have made sure that make all built the libraries and the tests, rather than just the tests.
That being said, is Qt Creator linking the leveldb and boost libraries properly? I've never used Qt Creator because command line compilation is just:
qmake && make . But, from your pastebin, it looks like it can't find leveldb or boost... so perhaps
making sure Qt Creator knows where the libraries are is the answer.
