Is that true for all systems, even those where the usual shared library extension is different, e.g., .sl on HP-UX systems, .dll on w32 ones, etc.? You can avoid warnings about the 'lib' prefix by making these things modules instead of libraries, as in lib_LTLIBRARIES = opengl.la opengl_la_LDFLAGS = -module -avoid-version that will under the hood create a .so in the hidden .libs (or _libs) subdirectory, and install them in the right place. For modules however, it is suggested to put them in package-specific directories such as pkglibdir not in libdir; you'd get the former by adding them to pkglib_LIBRARIES instead. > INCLUDES = -I$(srcdir)/include -I/usr/include/lua5.1 -I/usr/include/GL This is ok, but INCLUDES is an old name; use AM_CPPFLAGS instead. > LIBS = -shared This is wrong and broken. LIBS is only for libraries, -l and -L flags. For other link flags, use AM_LDFLAGS or per-target flags like in my example above. The -shared flag should not be needed at all for libraries created by libtool, however: it will add that flags for you it appropriate (or another one for a different compiler). > $ autoreconf -i > libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and > libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree. > libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am. You can avoid those warnings by heeding them, and creating a m4 directory in your tree. > opengl/Makefile.am:4: `opengl.so' is not a standard libtool library name > opengl/Makefile.am:4: did you mean `libopengl.la'? > autoreconf: automake failed with exit status: 1 Hope that helps.
