U_HEADERS = \ a.h
noinst_HEADERS = \ $(U_HEADERS) \ b.h
The manual says I can do that
When examining a variable definition, Automake will recursively examine variables referenced in the definition. For example, if Automake is looking at the content of foo_SOURCES in this snippet
xs = a.c b.c
foo_SOURCES = c.c $(xs)but I get an ": invalid variable `U_HEADERS'" error.
$ automake --version automake (GNU automake) 1.6.3
