I am trying to install gegl in my ubuntu machine 14.0. I configured and installed babl. However, when I run make I keep getting the following error: gegl:noise-hsv babl-format.c:656 babl_format() babl_format("HSVA float"): not found Could not attach to process. If your uid matches the uid of the target process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Operation not permitted. /tmp/babl.gdb:1: Error in sourced command file: No stack. make[2]: *** [examples] Error 255 Can somebody please tell me what I am required to do to fix this error?
