When compiling my first haskell program (the program on p. 71-72 of RWH), which I have in a file called hhask.hs, I got the following warning: $ ghc --make hhask [1 of 1] Compiling Main ( hhask.hs, hhask.o ) Linking hhask ... /usr/bin/ld: warning -F: directory name (/Users/me/Library/Frameworks) does not exist The program works fine, but I'm wondering about that warning. Does that mean I installed haskell in the wrong place? I installed haskell only last week on osx 10.4.11, and here is what I did: 1) I downloaded GMP.framework and GNUreadline.framework, which my mac automatically unzipped and placed on my desktop. I then dragged the resulting two folders into Library/Frameworks as per the instructions at: http://www.haskell.org/ghc/download_ghc_682.html#macosxintel 2) I downloaded ghc-6.8.2 3) I unzipped and untared into: /Users/me/my_tar_extractions 4) I cd'ed into the newly created ghc-6.8.2 folder. The full path to that folder is: /Users/me/my_tar_extractions/ghc-6.8.2 5) I read the INSTALL document in the ghc-6.8.2 folder. 6) I ran the command: $ ./configure 7) Then I rand the command: $ sudo make install 8) At the end of the install output, I got a message that said: ------------- Installation of ghc-6.8.2 was successful. To use, add /usr/local/bin to your PATH. Warning: this binary distribution does NOT contain documentation! -------------- 9) I appended /usr/local/bin onto the PATH in ~/.bash_profile.
