I compile a 32-bit under RHEL3 X86_64. I always get a error message :
ld: Relocatable linking with relocations from format elf64-x86-64 (/redhat30/STDLIB__.o) to format elf32-i386 (csrc/libvhdl_object.o) is not supported
Do someone know how to resolve this program?
I know I have to design a synchronizer with 2 F.F to pass one signal comes from low frequency clock domain to high frequency clock domain. But If a signal comes from A clock domain with fixed clock frequency must be passed to B clock domain. And clock of B clock domain is adjustable. It's...
