ATF-CONFIG(1) BSD General Commands Manual ATF-CONFIG(1)NAMEatf-config — queries static configuration information of ATF
SYNOPSISatf-config [-t] [var1 [.. varN]]
atf-config-h
DESCRIPTIONatf-config is a utility that queries static configuration information of
ATF. Static configuration refers to all those values for settings that
were built into the ATF binaries at build time.
In the first synopsis form, atf-config will print variable-value pairs
for all built-in static variables if no variable names are provided as
arguments. If any is provided, it will only print the variable-value
pairs for those variables. The output of the utility does not use the
‘=’ symbol to separate the variable name from its corresponding value in
an attempt to avoid sourcing the output in shell scripts or Makefiles.
If you need to do that, the -t flag allows you to query the value of
individual variables without any surrounding text.
In the second synopsis form, atf-config will print information about all
supported options and their purpose.
The following options are available:
-h Shows a short summary of all available options and their purpose.
-t Changes the output of the utility to show the variable values, one
per line, without the variable names.
Static configuration variables
The following list describes all the variables that are part of ATF's
static configuration:
atf_arch The architecture name detected by ATF. This is
derived from atf_machine because it is a subset of
it. Given that this name might be misdetected, it
is provided to the user as a configuration variable
so that he can fix its value temporarily until a
real fix is incorporated into mainstream sources.
atf_build_cc The C compiler used by the ATF checks that provide
build-time tests.
atf_build_cflags The C compiler flags used by the ATF checks that
provide build-time tests.
atf_build_cpp The C/C++ preprocessor used by the ATF checks that
provide build-time tests.
atf_build_cppflags The C/C++ preprocessor flags used by the ATF checks
that provide build-time tests.
atf_build_cxx The C++ compiler used by the ATF checks that pro‐
vide build-time tests.
atf_build_cxxflags The C++ compiler flags used by the ATF checks that
provide build-time tests.
atf_confdir The path to the directory that contains the system-
wide configuration files for ATF.
atf_includedir The path to the directory that contains the ATF
header files.
atf_libdir The path to the directory that contains the ATF
libraries.
atf_libexecdir The path to the directory that contains the auxil‐
iary utilities of ATF, used internally by the pub‐
lic tools.
atf_machine The machine type name detected by ATF. This should
not be tunable but is provided for symmetry with
atf_arch.
atf_pkgdatadir The path to the directory that contains the files
that form the ATF's shell-scripting library.
atf_shell The path to the shell interpreter that will be used
by ATF.
atf_workdir The path to the temporary directory that the utili‐
ties and the test programs will use to store tempo‐
rary files in.
ENVIRONMENT
Every variable that is part of the static configuration can be overridden
at run-time by defining an environment variable. This environment vari‐
able has the exact same name as the one shown by atf-config except that
the name is all composed of uppercase letters.
In general, empty values in the environment will be ignored unless other‐
wise noted below.
The recognized environment variables are:
ATF_ARCH Overrides the built-in value of atf_arch.
ATF_BUILD_CC Overrides the built-in value of atf_build_cc.
ATF_BUILD_CFLAGS Overrides the built-in value of atf_build_cflags.
Empty values are allowed.
ATF_BUILD_CPP Overrides the built-in value of atf_build_cpp.
ATF_BUILD_CPPFLAGS Overrides the built-in value of atf_build_cppflags.
Empty values are allowed.
ATF_BUILD_CXX Overrides the built-in value of atf_build_cxx.
ATF_BUILD_CXXFLAGS Overrides the built-in value of atf_build_cxxflags.
Empty values are allowed.
ATF_CONFDIR Overrides the built-in value of atf_confdir.
ATF_INCLUDEDIR Overrides the built-in value of atf_includedir.
ATF_LIBDIR Overrides the built-in value of atf_libdir.
ATF_LIBEXECDIR Overrides the built-in value of atf_libexecdir.
ATF_MACHINE Overrides the built-in value of atf_machine.
ATF_PKGDATADIR Overrides the built-in value of atf_pkgdatadir.
ATF_SHELL Overrides the built-in value of atf_shell.
ATF_WORKDIR Overrides the built-in value of atf_workdir.
