building a program with ghc
Hello, I am trying to write rules in order to build a program with ghc I end up with this, I think that I could improve all this a lot. So I would like your advices in order to improve this thanks for considering Frederic GHCLINK = $(LIBTOOL) $(AM_V_lt) --tag=CC $(AM_LIBTOOLFLAGS) \ $(LIBTOOLFLAGS) --mode=link $(GHC) $(AM_CFLAGS) $(CFLAGS) \ $(AM_LDFLAGS) $(LDFLAGS) -o $@ .hsc.o: # fake in order to let automake generate clean rules for _OBJECTS files hsc2hs --cflag=$(AM_CFLAGS) -o $@ $< .hs.o: # fake in order to let automake generate clean rules for _OBJECTS files ghc --make -i$(srcdir)/src -i$(builddir)/src -outputdir=$(builddir)/src -c -O -o $@ $< hsc_sources=\ src/Hkl/C/Hkl.hsc \ src/Hkl/C/Binoculars.hsc sources=\ src/Hkl.hs \ src/Hkl/Binoculars.hs \ src/Hkl/Binoculars/Command.hs \ src/Hkl/Binoculars/Common.hs \ src/Hkl/Binoculars/Config.hs \ ...

Hi,
I am facing a problem with libtool. While installing it complains
a
relink required and while doing so it tries to link against the
shared library instead of static library.
Well, the problem is better explained in this thread
http://sourceware.org/ml/automake/2004-07/msg00127.html with
example
code.
I am facing exactly the same problem.
I saw a similar problem in this thread also
http://www.mail-archive.com/libtool@gnu.org/msg00782.html
Is there a solution available for this?
Thanks

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

embeding a shared library into another one
Hello I am using the bullet project [1] The author said that the best things to do is to statically link the libraries provided by their projetc. so I copy the bullet sources into my own project ans add a configure.ac AC_CONFIG_SUBDIRS(/path/to/bullet) now I create my how library which use thie bullet libraries. So I add for my library AM_LDFLAGS = -version-info 0:0:0 \ $(HKL_LIBS) \ $(G3D_LIBS) \ ./bullet/src/libbulletmath.la \ ./bullet/src/libbulletcollision.la lib_LTLIBRARIES = \ libhkl3d.la libhkl3d_la_SOURCES = \ hkl3d.cpp Now my problem is : I want to embed the code of bullet in my share library that way A programm using my library just need to link agains my hkl3d library. A sort of : link all .os object of bullet into my own library How can I do this ? thanks Frederic [1] http://bulletphysics.org/wordpress/
