[CLN-list] CLN on a 64-bit Macintosh

To whoever can answer this question, I downloaded and installed CLN and XCODE on a Macintosh GR4, which is a 32-bit computer, and it works, but later I downloaded and installed CLN and XCODE on a Macbook Pro 15 inch laptop, which is a 64-bit computer, and it doesn't work. The technician at my university is trying to make it work, but so far without success. Can any of you suggest a fix? Yours sincerely, Timothy Walsh P.S. Is there a way in C to declare an integer to be 64 bits long? ------------------------------------------------- Uqam Service IMP: http://www.er.uqam.ca/courrier
