Description John Reiser 2012-04-04 02:18:12 UTC 
Description of problem: The symbol 'atan2' is undefined in $libdir/liba2ps.so.1. This will cause an application crash if referenced.


Version-Release number of selected component (if applicable):
a2ps-4.14-14.fc17.x86_64


How reproducible: every time


Steps to Reproduce:
1. readelf --symbols /lib*/liba2ps.so.* | grep atan2
2.
3.
  
Actual results:
    24: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT  UND atan2


Expected results: No unresolved symbols


Additional info: Fix is: add "-lm" to the libraries when building liba2ps.so.1.
Comment 1 John Reiser 2012-04-04 02:24:09 UTC 
Additional piece that is needed to confirm this is a bug:
  $ ldd /lib*/liba2ps.so.1
	linux-vdso.so.1 =>  (0x00007fffac58b000)
	libc.so.6 => /lib64/libc.so.6 (0x0000003d97400000)
	/lib64/ld-linux-x86-64.so.2 (0x0000003d97000000)
which does not include libmath (-lm).
