make: *** [atscap] Error 1

It builds fine on my fc6 i386 install

Version-Release number of selected component (if applicable):
glibc-2.4-11

How reproducible:
Every time

Steps to Reproduce:
1. Download atscap from http://70.247.38.254/dtv/
2. untar it, and run make
Comment 1 Jakub Jelinek 2007-03-30 02:18:12 EDT
That's the program's fault, it simply has never been ported to non-i386.
There is no %eip register on x86_64 (but %rip; and on other arches it has
even different names, or is represented by multiple registers etc.), so x86_64
defines REG_RIP instead.
Comment 2 Joseph Shraibman 2007-03-30 11:07:31 EDT
And here I thought that x86_64 was completely reverse compatible.  Thanks for
clearing it up for me.
Comment 3 Jakub Jelinek 2007-03-30 11:21:13 EDT
If you build a 32-bit program, it is.  But you are building a 64-bit one.
