Hello Vincent,

Thanks for the bug report.

I'm compiling two libraries with the options -fprofile-arcs
-ftest-coverage passed to gcc.

The first one has .gcno files in his directory and the .libs sub
directory. The second one has .gcno files in his directory but not in the
.libs subdir. I paste below the Makefile.am of eash lib:

[...]

clean-local:
        @rm -rf *.gcno

BTW, why the '@' here?  There's nothing wrong with showing this command
(but of course it doesn't matter much either).

I agree, it even be usefull to see such commands

there is a difference in the creation of the libs.

libtool explicitely removes the .gcno files in the 2nd case:

libtool: link: rm -fr  .libs/eina_chained_mempool.gcno

does someone know why libtool remove the .gcno files.

Not yet, but it does sound like a bug (in either Libtool or Autoconf).
You could really help us find this bug more easily by trying to reduce
this to a small example package that exposes the issue for you, and show
how exactly you configured and built the package.  The files
configure.ac, Makefile.am, and one library source file, should probably
be sufficient.  If that's too much work for you, then please at least
post how you configured and built the second package (all command lines
plus all of their output), and also post config.log.  Please gzip large
files, thank you.

for the source code: see the attached file autotools.tar.bz2

for the configuration:

autoreconf -f -i
./configure
make

for the output : output.log.bz2
for config.log : config.log.bz2

BTW, which Libtool and Autoconf versions do you use?

autoconf 2.62
libtool 2.2.5a



thanks

Vincent Torri

for libtool, it's a git version that I have grabbed just after cegcc was added. PS: if you note things that are wrong in configure.ac, please don't hesitate to tell me.
