@ -105,23 +105,33 @@ Modify the VPATH variable in your Makefile.am:
Notice the use of "+=": it is necessary for the vpath builds to work.
Add wordsplit.o to the name_LIBADD or name_LDADD variable, depending on
the nature of the object being built.
Define the nodist_program_SOURCES variable:
Modify AM_CPPFLAGS as shown in the previous section:
nodist_program_SOURCES = wordsplit.c
AM_CPPFLAGS = -I$(srcdir)/wordsplit
The nodist_ prefix is necessary to prevent Make from trying to
distribute this file from the current directory (where it doesn't
exist of course). It will find it using VPATH during compilation.
Add both wordsplit/wordsplit.c and wordsplit/wordsplit.h to the EXTRA_DIST
variable.
Finally, add both wordsplit/wordsplit.c and wordsplit/wordsplit.h to
the EXTRA_DIST variable and modify AM_CPPFLAGS as shown in the
previous section.
An example Makefile.am:
program_SOURCES = main.c
LDADD = wordsplit.o
noinst_HEADERS = wordsplit/wordsplit.h
nodist_program_SOURCES = wordsplit.c
VPATH += $(srcdir)/wordsplit
EXTRA_DIST = wordsplit/wordsplit.c wordsplit/wordsplit.h
AM_CPPFLAGS = -I$(srcdir)/wordsplit
It is also possible to use LDADD as shown in the example below:
program_SOURCES = main.c
LDADD = wordsplit.o
VPATH += $(srcdir)/wordsplit
EXTRA_DIST = wordsplit/wordsplit.c wordsplit/wordsplit.h
AM_CPPFLAGS = -I$(srcdir)/wordsplit
