#-----------------------------------------------------------------------------
# GNU makefile for building WCSLIB 6.2 and its test suite.
#
# Summary of the main targets
# ---------------------------
#   build:     Build the library.
#
#   clean:     Delete intermediate object files.
#
#   cleaner:   clean, and also delete the test executables.
#
#   cleanest (distclean or realclean): cleaner, and also delete the object
#              library and the C source files generated by 'flex'.
#
#   check (or test): Compile and run the test programs.  By default they are
#              executed in batch mode, and non-graphical tests only report
#              "PASS" on success.  Use
#
#                make MODE=interactive check
#
#              to run them interactively with full diagnostic output.  To skip
#              graphical tests even if PGPLOT is available, use
#
#                make CHECK=nopgplot check
#
#   tests:     Compile the test programs (but don't run them).
#
# Notes:
#   1) If you need to make changes then preferably modify ../makedefs.in
#      instead and re-run configure.
