dnl -----------------------------------------------------------
|
|
dnl Check for package defined by header and libs, and probably
|
|
dnl located in dir-prefix, possibly with libs in libdir-prefix.
|
|
dnl Both dir-prefix and libdir-prefix can be empty. Will set
|
|
dnl prefix_{CPPFLAGS, LDFLAGS, LIBS} as needed.
|
|
dnl
|
|
dnl The general intent of this macro is to provide finer-grained scoping
|
|
dnl of C preprocessor flags, linker flags, and libraries (as opposed to
|
|
dnl unconditionally adding to the top-level CPFLAGS, LDFLAGS, and LIBS,
|
|
dnl which get used to compile/link *everything*).
|
|
dnl
|
|
dnl Here is a breakdown of the parameters:
|
|
dnl
|
|
dnl * prefix: the macro sets $prefix_CPPFLAGS, $prefix_LDFLAGS, and
|
|
dnl $prefix_LIBS (and AC_SUBSTs all of them). For example, if a
|
|
dnl provider uses this macro to check for a header/library that it
|
|
dnl needs, it might well set prefix to be its provider name.
|
|
dnl * header_filename: the foo.h file to check for
|
|
dnl * library_name / function_name: check for function function_name in
|
|
dnl -llibrary_name. Specifically, for library_name, use the "foo" form,
|
|
dnl as opposed to "libfoo".
|
|
dnl * extra_libraries: if the library_name you are checking for requires
|
|
dnl additonal -l arguments to link successfully, list them here.
|
|
dnl * dir_prefix: if the header/library is located in a non-standard
|
|
dnl location (e.g., /opt/foo as opposed to /usr), list it here
|
|
dnl * libdir_prefix: if the library is not under $dir_prefix/lib or
|
|
dnl $dir_prefix/lib64, list it here.
|
|
dnl * action_if_found: if both the header and library are found and
|
|
dnl usable, execute action_if_found
|
|
dnl * action_if_not_found: otherwise, execute action_if_not_found
|
|
dnl * extra_includes: if including header_filename requires additional
|
|
dnl headers to be included first, list them here
|
|
dnl
|
|
dnl The output _CPPFLAGS, _LDFLAGS, and _LIBS can be used to limit the
|
|
dnl scope various flags in Makefiles.
