It should be fooplug_LIBTOOLFLAGS = --tag=disable-static instead. The *_LIBTOOLFLAGS is like other per-target flags such as *_LDFLAGS; the only difference is that it comes earlier on the libtool command line, and that it is used for compile mode (and other modes) as well; for example --silent can be put in there. > But is there also a way to define fooplugs_LIBTOOLFLAGS somewhere > in configure.ac, so, that - in case you're having a rather big project - you > don't need to define the libtool flags for this "target" everytime? Hmm. Whenever no per-target flags are given, AM_LIBTOOLFLAGS will be used. Depending on whether most of your LTLIBRARIES are modules or not, you could set AM_LIBTOOLFLAGS and override for the non-modules, in the example above by setting `libfoo_la_LIBTOOLFLAGS ='. Of course you can also AC_SUBST()itute the *_LIBTOOLFLAGS variables from configure.ac, but I guess that won't save you from getting all their names right. > Although, I never played with targets yet, i'm quite new to them though :) Well, you've already used per-target LDFLAGS. > > Further, I should be advising against removing installed .la files. > > While they may not help you much, they are usually of more help to > > users that install software below nonstandard locations. > > for shared libraries I do totally agree, but how could they help for dso's > that are dlopen()'d only? Well, if only for the simple reason that if you (or another software that would like to use your modules) also use libltdl's lt_dlopen, it needs these files in general. Hope that helps. Cheers, Ralf
