Re: How to revise automake.am

[Zhi Qing Wu]

Thanks for your quick reply. By following your advice,
 I did some changes to Makefile.am:

The original Makefile.am:
...
modpermisdir = $(libexecdir)
modpermis_LTLIBRARIES = mod_permis.la
mod_permis_la_SOURCES = mod_permis.cpp
mod_permis_la_CXXFLAGS = $(APXS_CFLAGS)
-I$(APXS_INCLUDE) $(RPC_CFLAGS) $(LIBGCJ_CXXFLAGS)
mod_permis_la_LDFLAGS = -module -avoid-version
...

The revised Makefile.am:
...
modpermisdir = $(libexecdir)
modpermis_LTLIBRARIES = mod_permis.la
mod_permis_la_SOURCES = mod_permis.cpp
mod_permis_la_CXXFLAGS = $(APXS_CFLAGS)
-I$(APXS_INCLUDE)
/home/zhiqing/tmp/shibboleth-1.2/apache $(RPC_CFLAGS)
$(LIBGCJ_CXXFLAGS)
mod_permis_la_LDFLAGS = -lgcj -module -avoid-version
mod_permis_la_LDADD =
/usr/lib/gcc-lib/i386-redhat-linux/3.3.2/libotherclass.so

"otherclass" is the class I need to add to the program
mod_permis.cpp (belong to the project)
Directory "/home/zhiqing/tmp/shibboleth-1.2/apache"
contains otherclass.h
and mod_permis_la_LDADD points to the shared library
"libotherclass.so"

Yes, the project uses Libtool.

The compilation result shows:
apache/Makefile.am:44: use `mod_permis_la_LIBADD', not
`mod_permis_la_LDADD'
/usr/share/automake-1.7/am/depend2.am: am__fastdepCXX
does not appear in AM_CONDITIONAL
....
and other errors.

I have read
info '(automake.info)Java Support'
Without much experience in customing Makefile.am, I am
not sure what to do next.
