Greetings all GEMPAK users and experts, I'm writing to you today in hopes of receiving help/advice on installing GEMPAK on my 2011 intel MacBook Pro.. I have been trying to now for going on almost 48 hours trying to get past step four (4) in the GEMPAK 6.6.0 instructions for Mac OS X.. I'm not a complete newbie to installing programs from source on my computer. I have done it several times, albeit with general instructions. But without instructions I'm lost when it comes to the process. Usually it's just a few quick commands in Terminal and it's over, maybe the occasional Fink or MacPort dependency to download, but nothing to complicated. Now step four (4) of the instructions state: "Extract the GEMPAK tarball archive obtained from the *GEMPAK Downloads*<http://www.unidata.ucar.edu/downloads/gempak/nawips-6.6.0/source/index.jsp>page and modify Gemenviron or Gemenviron.profile depending on your shell so that the environmental variable $NAWIPS is set to the correct directory path. Then cd into the $NAWIPS directory (this is the parent directory of the GEMPAK/N-AWIPS directory tree). "... Up to this point I have followed the instructions completely, even deleting my copy of Fink to use MacPorts as the instructions refer to numerous times. I have followed all these instructions to a T! I downloaded the GEMPAK file and extracted the tarball file. Because the Terminal on my Mac uses the "Bash" shell, I navigated to the Gemenviron.profile file with in the GEMPAK-6.6.0 folder and opened in text editor. Now, I moved the extracted GEMPAK folder that was created after extracting the tarball file around a few times first migrating it to a hidden gempak directory that I created within my Home user directory.. I also had it in a visible directory in the same Home directory. What is hanging me up is the instructions are really kind of vague for a "Terminal" dummy like me.. I opened the file, I found the line which the instructions and file both say to change, but I don't know WHAT the correct path would be.. Everything that is stated in the directions leading up to this step has most everything located in the .../opt/local/... directory or somewhere within it. So, I guess my first question would be - 1.) Is this where I should put the resulting GEMPAK 6.6.0 folder that is created during the tarball extraction? 2.) What is the "correct directory path" as it's put in step four (4)? 3.) After this it says to change directory (cd) into the $NAWIPS directory (this is the parent directory of the GEMPAK/N-AWIPS directory tree). Almost directly after this statement it says to, "Be sure you are cd'd into the top level GEMPAK6.6.0 directory at this time."... What is the top level directory that they're referring to, the actual GEMPAK folder that was extracted from tarball or the directory within which GEMPAK will be located? (I know basic file structure, and the concepts are fairly similar across the board for all OS's.. At least in the sense that most OS's have a hierarchical file system, wherein lower levels of folders and files are stored within higher level folders/directory.) 4.) Where is this bloody NAWIPS folder/directory that keeps getting referred to besides in the gemenviron files? It can't be found anywhere. Numerous hours of looking fervently have turned up nothing! 5.) After the "Be sure you're in the NAWIPS top directory..." it says to type "make > make.out", but when I do Terminal just tells me that "make: *** /: Is a directory. Stop." and thats it (I tried this after I though I had everything in order and ready to start compiling... But nothing ever happened, except it just made an additional file in the GEMPAK 6.6.0 directory created after extracting the tarball with absolutely nothing in the file it created.) Any help that anybody could give me, especially anybody with expertise in installing GEMPAK on Mac OS X 10.6, would be GREATLY appreciated!!! As I stated earlier, I've been trying now for over 48 hours straight trying to get the program to compile and install.. I thought I was doing a good job following the instructions exactly to the letter, and figured I wouldn't have a single problem because of following the directions so strictly... But I'm still nowhere near having it installed, I fear, and am beginning to have my doubts that I'll ever have a successful installation on my computer... Thank you all who help for your time! Sincerely, Blake H.
