As I see it, the only real way to play it safe here, per POSIX, is to
forgo the use of nested variables altogether.
Exactly. Hence the proposal for a configure-time check, which expands
to the extension where the extension was tested to work, and which
expands to an innocuous variant that avoids nested variables where the
test fails.
I remember one old discussion from automake list that end with following
solution
lib_LTLIBRARIES = @[email protected]
@MODULE@_la_SOURCES = module.c
@MODULE@_la_LDFLAGS = -module -avoid-version
Following current discussion I think that next will be automake to be
able to process following Makefile.am
MODULE = @MODULE@
lib_LTLIBRARIES = $(MODULE).la
$(MODULE)_la_SOURCES = module.c
$(MODULE)_la_LDFLAGS = -module -avoid-version
I think that is too early to request such automake functionality .
