Hi Santhosh,
I suggest writing your *_LTLIBRARIES with a comment in front,
perhaps
with # to differ between disabled and enabled libraries. Then
using
grep(1) to extract the names and the same tools to extract the
dependencies. You can then use tsort(1) to topologically sort the
libraries and write the actual ${dir}_LTLIBRARIES to an included
.am
file. Semantically, this is what I do. In reality, I wrote a
preprocessor
for automake that does this, but I don't suggest using it, as it's
beta
and very much tailored to my needs.
Hi Pippijn
Thank you for taking time and trying to help us... because we really
get
stucked.
I tried to understand your answer but I honestly think I'm not good
enough with automake to be able to understand and apply your
methodology. I also doubt that the other cases given by Santhosh are
the
same as our, although the symptom is.
From my understanding the previously described issues occur if the
dependences are not compiled in the right order. I think this is not
our
problem because at the moment the error occurs, I know the
dependence is
already compiled.
The issue occurs if the dependencies are not _installed_ in the right
order.
So, I'm sure the file $(top_builddir)/src/ctpp2/src/libctpp2.la
exists.
As you noted, the dependency has been compiled and linked, but for
installation, it has to be relinked:
libtool: relink: g++ -shared -nostdlib
^^
The above occurs in make install.
So my question is why automake replaces the path with libcttp2.la in
-lctpp2, replacing a static linking with a dynamic one?
It's related to rpath linking. The resulting binaries are relinked to
include $(libdir) as rpath, so that installed binaries can be called
and
libraries loaded without listing $(libdir) in LD_LIBRARY_PATH or
ld.so.conf.
It looks like you are using a recursive make, in your project. Are
you
sure that libcttp2.la exists in $(libdir)? As an experiment, try make
install in libctpp2's $(builddir) and then make install in
$(top_builddir).
So problem was fixed by using the noinst prefix for the ctpp2 code.
If I correctly have understood the autotools behaviour it seems that if
you don't use noinst prefix, the autotools install the libraries. In
our case this does not make sense as the *.la files are only linked one
time during the software compilation and not used afterwards (for
example from thirds projects).
Thx you again Pippijn vor your help, without your answer I wouldn't
have discover that the static lib were installed.
Regards
Emmanuel
