Wrong ELF Class: ELFCLASS64

Rookie here:

I am trying to compile my softare using cc -o myprog obj1.o obj2.o -lc
-lcurses.

I believe that my problem is being cause by the 32-bit curses library.
Is there a 64-bit curses library?
If there is, where is it usually located?
If only a 32-bit curses library exist, then I will have to compile my
program in 32-bit mode only.

Yes

On SXCE-b96, /lib/64 but there are symlinks in /usr/lib/64. You don't
have to specify the location since ld and ld.so.1 know how to find 64 bit
libraries.

If your program is 64-bit ready then add the compile argument -m64;

cc -m64 -o myprog ....

But your obj1.o and obj2.o will also have to be 64 bit.

To build only 32 bit objects, use -m32.

Thanks, I got it to compile and link. Now all I have to do is get
ncurses (initialization) to work correctly.
