Make install failure 64-bit OS X

[jctull]

I was able to successfully configure and compile 64-bit gdal as a framework for OS X 10.5.2 using svn revision 14012. When I try to install, the script moves into the 'port' directory, begins compiling, and fails. Here is the output from the 'sudo make install' command.

(cd port; make)
/bin/sh /Users/jctull/sources/gdal/libtool --mode=compile --tag=CXX g++ -arch x86_64 -isysroot /Developer/SDKs/MacOSX10.5.sdk -g -O2  -Wall  -DOGR_ENABLED -I/Users/jctull/sources/gdal/port 	 -DHAVE_CURL  -c -o cpl_hash_set.o cpl_hash_set.cpp

Even,

I think this is yours? I see the same problem on my system.

I think you may need to cast a pointer to a long, and then int if you really need it as int.

I'll take care of this if you aren't able to fix it conveniently in the next couple hours.

The function should use #ifdef's instead of "if (sizeof(void*) == 8)". "return (int) elt" would never be executed but the compiler isn't smart enough.

I've changed the type of the return value of the hash function to 'unsigned long' in r14021.

Could you confirm that it fixes the problem ?

The problem is now fixed. I successfully compiled and installed. Thanks!
