Re: cyclic dependancy

[Neel Basu]

When I compile/make I see this error.

make[2]: *** No rule to make target `../cgi++/jsutil/libcgixx-jsutil.la', 
needed by `cgixx'.

Here is my makifile.am

cgixx/Makefile.am
AUTOMAKE_OPTIONS = foreign 1.4
SUBDIRS = cgi++ src
#Doesn't order matter here ?? and I think cgi++ should come first.

cgixx/cgi++/Makefile.am
INCLUDES =
#It doesn't need to include anything else. rather others include this one.
METASOURCES = AUTO
lib_LTLIBRARIES = libcgixx.la
noinst_HEADERS =  NOT-MENTIONED
libcgixx_la_SOURCES = NOT_MENTIONED
SUBDIRS = jsutil

cgixx/cgi++/jusutil/Makefile.am
INCLUDES = -I$(top_srcdir)/cgi++
METASOURCES = AUTO
noinst_HEADERS = NOT-MENTIONED
lib_LIBRARIES = libcgixx-jsutil.a
libcgixx_jsutil_a_SOURCES = NOT-MENTIONED
libcgixx_jsutil_a_LIBADD = $(top_builddir)/cgi++/libcgixx.la

cgixx/src/MakeFile.am
bin_PROGRAMS = cgixx
cgixx_SOURCES = cgixx.cpp myapp.cpp

# set the include path found by configure
INCLUDES = -I$(top_srcdir)/cgi++ -I$(top_srcdir)/cgi++/jsutil $(all_includes)

# the library search path.
cgixx_LDFLAGS = $(all_libraries)
noinst_HEADERS = myapp.h
cgixx_LDADD = $(top_builddir)/cgi++/jsutil/libcgixx-jsutil.a \
        $(top_builddir)/cgi++/libcgixx.la 
$(top_builddir)/cgi++/jsutil/libcgixx-jsutil.la

Hope this makes it more clear.
