+This section contains the answers to questions that may arise when you are

+look in the other chapters, and if you still don't have the answer, ask on the
+pkgsrc-users mailing list.

+19.5. Why does make show-var VARNAME=BUILDLINK_PREFIX.foo say it's empty?
+
+19.1. What is the difference between MAKEFLAGS, .MAKEFLAGS and MAKE_FLAGS?
+
+ MAKEFLAGS are the flags passed to the pkgsrc-internal invocations of make
+ (1), while MAKE_FLAGS are the flags that are passed to the MAKE_PROGRAM
+ when building the package. [FIXME: What is .MAKEFLAGS for?]
+
+19.2. What is the difference between MAKE, GMAKE and MAKE_PROGRAM?
+
+ MAKE is the path to the make(1) program that is used in the pkgsrc
+ infrastructure. GMAKE is the path to GNU Make, but you need to say
+ USE_TOOLS+=gmake to use that. MAKE_PROGRAM is the path to the Make
+ program that is used for building the package.
+
+19.3. What is the difference between CC, PKG_CC and PKGSRC_COMPILER?
+
+ CC is the path to the real C compiler, which can be configured by the
+ pkgsrc user. PKG_CC is the path to the compiler wrapper. PKGSRC_COMPILER
+ is not a path to a compiler, but the type of compiler that should be

+Every directory in the regress category that contains a file called spec is
+considered a regression test. This file is a shell program that is included by
+the pkg_regress command. The following functions can be overridden to suit your
+needs.
+
+20.3.1. Overridable functions
+
+These functions do not take any parameters. They are all called in "set -e"
+mode, so you should be careful to check the exitcodes of any commands you run
+in the test.
+
+do_setup()
+
+ This function prepares the environment for the test. By default it does
+ nothing.
+
+do_test()
+
+ This function runs the actual test. By default, it calls TEST_MAKE with the
+ arguments MAKEARGS_TEST and writes its output including error messages into
+ the file TEST_OUTFILE.
+
+check_result()
+
+ This function is run after the test and is typically used to compare the
+ actual output from the one that is expected. It can make use of the various
+ helper functions from the next section.
+
+do_cleanup()
+
+ This function cleans everything up after the test has been run. By default
+ it does nothing.
+
+20.3.2. Helper functions
+
+exit_status(expected)
+
+ This function compares the exitcode of the do_test() function with its
+ first parameter. If they differ, the test will fail.
+
+output_require(regex...)
+
+ This function checks for each of its parameters if the output from do_test
+ () matches the extended regular expression. If it does not, the test will
+ fail.
+
+output_prohibit(regex...)
+
+ This function checks for each of its parameters if the output from do_test
+ () does not match the extended regular expression. If any of the regular
+ expressions matches, the test will fail.
