|
|
dnl of some commands and utilities needed to allow
|
|
dnl configure script bootstrapping itself when using

|

dnl code that performs PATH_SEPARATOR auto-detection
|
|
dnl and sets its value unless it is already set with
|
|
dnl a non-empty value.
|
|
dnl
|
|
dnl These basic checks are intended to be placed and
|
|
dnl executed as early as possible in the resulting
|
|
dnl configure script, and as such these must be pure
|
|
dnl and portable shell code.

dnl
|

dnl This macro may be used directly, or indirectly

|
dnl when using other macros that AC_REQUIRE it such

|
|
dnl
|
|
dnl Currently the mechanism used to ensure that this
|
|
dnl macro expands early enough in generated configure
|
|
dnl script is making it override autoconf and libtool
|

dnl PATH_SEPARATOR check.

dnl XC_CHECK_PATH_SEPARATOR
|
|
dnl -------------------------------------------------
|
|
dnl Public macro.
|
|
dnl
|
|
dnl Usage of this macro ensures that generated configure
|
|
dnl script uses the same PATH_SEPARATOR check irrespective
|
|
dnl of autoconf or libtool version being used to generate
|
|
dnl configure script.
|
|
dnl
|
|
dnl Emits shell code that computes the path separator
|
|
dnl and stores the result in 'PATH_SEPARATOR', unless
|
|
dnl the user has already set it with a non-empty value.
|
|
dnl
|
|
dnl This path separator is the symbol used to separate
|
|
dnl or diferentiate paths inside the 'PATH' environment
|
|
dnl variable.
|
|
dnl
|
|
dnl Non-empty user provided 'PATH_SEPARATOR' always
|
|
dnl overrides the auto-detected one.
|
|
dnl
|
|
dnl Strictly speaking the check is done in two steps. The
|
|
dnl first, which does the actual check, takes place in
|
|
dnl XC_CONFIGURE_PREAMBLE macro and happens very early in
|
|
dnl generated configure script. The second one shows and
|
|
dnl logs the result of the check into config.log at a later
|
|
dnl configure stage. Placement of this second stage in
|
|
dnl generated configure script will be done where first
|
|
dnl direct or indirect usage of this macro happens.
