I still get about twenty errors like: checking zlib.h usability... no checking zlib.h presence... yes configure: WARNING: zlib.h: present but cannot be compiled configure: WARNING: zlib.h: check for missing prerequisite headers? configure: WARNING: zlib.h: see the Autoconf documentation configure: WARNING: zlib.h: section "Present But Cannot Be Compiled" configure: WARNING: zlib.h: proceeding with the preprocessor's result configure: WARNING: zlib.h: in the future, the compiler will take precedence configure: WARNING: ## ---------------------------------------- ## configure: WARNING: ## Report this to pgsql-b...@postgresql.org ## configure: WARNING: ## ---------------------------------------- ## But it seems that I'm using older clang: Debian clang version 3.2-7ubuntu1 (tags/RELEASE_32/final) (based on LLVM 3.2) Target: x86_64-pc-linux-gnu Thread model: posix So maybe that's the problem, I will update clang and try once again. thanks, Szymon
