Notes: When running a configure script that has nested packages (for example libcurl's configure with --enable-ares and c-ares sources embedded in curl tree) and AC_CONFIG_SUBDIRS([nested-subdir]) machinery is used to automatically run the nested configure script from within the parent configure script, it happens that the nested _shell_ script will inherit shell variables exported from the parent _shell_ script. If for example parent configure script sets and exports LDFLAGS and LIBS variables with proper values in order to link either a parent library or program with a library which will be configured and built by a nested package; It will happen that when the nested configure script runs, the nested library does not exist yet and _any_ link-test done in the nested configure will fail, such as those that autoconf macros perform in order to detect existing compiler and its characteristics, the result is that the nested configure script will fail with errors such as: configure: error: C compiler cannot create executables For now, we no longer export variables previously exported here. On the other hand, AC_SUBST'ing them is appropriate and even with nested packages each package's config.status gets its own package values. So we reinstate AC_SUBST'ing previously AC_SUBST'ed variables. |
