Hello, All of a sudden, the package regex-posix-0.94.2 failed to link after i installed a couple of other packages (http, json). When I try to reinstall it, I got the folowing errors:
D:\projets\crete1941>cabal install --global --reinstall --enable-documentation regex-posix-0.94.2 Resolving dependencies... Configuring regex-posix-0.94.2... Preprocessing library regex-posix-0.94.2... Text\Regex\Posix\Wrap.hsc:107:19: regex.h: No such file or directory
This is the crucial line in this particular build failure, everything else is fluff. I really, really wish gcc would learn to stop compiling after a header file was missing, since it almost always results in large amounts of nonsense errors. It looks like cabal-install or possibly Cabal can't find your headers. I notice you're compiling with an explicit --global option - why is that? Is it currently installed locally or globally? You can use 'ghc-pkg list regex-posix' to check. You can also enable global installs and documentation by default by editing your config file, whose location is given in the output of cabal --help. You can also specify extra-include-dirs there if you need to do that.
