If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is.If the library file does exist, it may contain errors that are caught by the C compiler at the preprocessing stage. In this case you can re-run configure with the verbosity flag -v3 to see the error messages. cabal: Leaving directory '/tmp/cabal-tmp-9613/posix-api-0.3.5.0' Completed bytebuild-0.3.8.0 cabal: Error: some packages failed to install: bytelog-0.1.1.0-36ixxJ02wAj4kF41e1rzGN depends on bytelog-0.1.1.0 which failed to install. posix-api-0.3.5.0-HHoMYpMDaFuAE8JYtJHfwg failed during the configure step.
