Why do I see two libasan packages on Red Hat Enterprise Linux 7?

Solution Verified - Updated -


  • gcc build fails if -fsanitize=address option is enabled.
gcc -Wall -pedantic -ansi testme.c -o testme -fsanitize=address
/usr/bin/ld: cannot find /usr/lib64/libasan.so.0.0.0
collect2: error: ld returned 1 exit status

But installing libasan # yum install libasan provides /usr/lib64/libasan.so.1


  • Red Hat enterprise Linux 7
  • gcc-4.8.x-xx.el7
  • libasan-4.8.x-xx.el7
  • libasan-4.9.2-6.2.el7.x86_64 [Developer Toolset 3, Software Collections 1.2]
