Hi, I get the following error while I tried installing the ByteString package. Could you please help me resolve this >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> C:\Users> cabal install bytestring Resolving dependencies... Configuring bytestring-0.10.4.1... Failed to install bytestring-0.10.4.1 Last 10 lines of the build log ( C:\Users\AppData\Roaming\caba l\logs\bytestring-0.10.4.1.log ): setup-Cabal-1.18.1.3-i386-windows-ghc-7.8.3.exe: Missing dependency on a foreign library: * Missing (or bad) header file: fpstring.h This problem can usually be solved by installing the system package that provides this library (you may need the "-dev" version). 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 header 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: Error: some packages failed to install: bytestring-0.10.4.1 failed during the configure step. The exception was: ExitFailure 1>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Regards,Abhinav
