Jennie,

you might also want to check, if your system & compiler are actually capable of producing 64-bit binaries, and if so, whether the default of your compiler is 32- or 64-bit. E.g.:

echo -e '#include \n#include \nint main() {\nprintf("Hello\\n");\nreturn 0;\n}' | tee hello.c ; gcc -o hello hello.c && ./hello ; gcc -m32 -o hello32 hello.c && ./hello32 ; gcc -m64 -o hello64 hello.c && ./hello64 ; file hello{,32,64}

or even echo -e '#include \n#include \nint main() {\nprintf("Hello(%d,%d)\\n",8*sizeof(char*),8*sizeof(size_t));\nreturn 0;\n}' | tee hello.c ; gcc -o hello hello.c && ./hello ; gcc -m32 -o hello32 hello.c && ./hello32 ; gcc -m64 -o hello64 hello.c && ./hello64 ; file hello{,32,64}

In case "hello" (the default) is 64-bit, you don't need to use --enable-bits=64 at all.

In case "hello64" does not compiler or work, there is not much hope to get a 64-bit MonetDB on your system (at least not easily).

Could you please also report what uname -a says on your system?
