I noticed a bug in fsa-0.9.4: when an XML file is read in which an arc
has no weight specified then the weight will be uninitialized and may
be a random value.
The behavior occurred on an Intel(R) Xeon(TM) CPU 3.06GHz system,
after compiling with gcc-3.4.4. For example, the arc weight in the
src/Tools/Fsa/examples/closure-1.fsa machine is -1.792753, or
-1.829887, different on every run, instead of 0.
To fix the bug, insert the line
arc_->weight_ = fsa_->semiring()->one();
in src/Fsa/StorageXml.cc, after line 97, so that you have
arc_->output_ = Epsilon;
arc_->weight_ = fsa_->semiring()->one();

Hello,
I have been unable to compile the library. I've tried with GCC 3.4.4 and
GCC 4.0.2. I get this error message:
BinaryStream.cc:105: warning: specialization of 'template<class T> bool
Core::BinaryOutputStream::write(const T*, std::streamsize)' in different namespace
BinaryStream.hh:136: warning: from definition of 'template<class T> bool
Core::BinaryOutputStream::write(const T*, std::streamsize)'
BinaryStream.cc: In member function 'bool
Core::BinaryOutputStream::write(const T*, std::streamsize) [with T = bool]':
BinaryStream.cc:105: internal compiler error: in comptypes, at cp/typeck.c:942
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
If I comment out those errors, I still get this:
Parameter.cc:174: warning: extra ';'
Parameter.cc:179: error: expected unqualified-id before ';' token
Parameter.cc:180: error: expected unqualified-id before ';' token
Parameter.cc:181: error: expected unqualified-id before ';' token

Parameter.cc:187: error: expected unqualified-id before ';' token
Parameter.cc:188: error: expected unqualified-id before ';' token
Parameter.cc:189: error: expected unqualified-id before ';' token
>From my understanding of the internal compiler error in the first error,
is that it has so to do with the type checker failing when it tries to
compare two types. It seems that both these errors have to do with
template specilization.
Any suggestions on what I can do to compile the code? Should I downgrade
GCC to 3.2 (which is what you quote in the README)?

Hi!
I'm proud to announce version 0.9.3 of the RWTH FSA toolkit. It's a
maintainance release this time that fixes 2 small compilation problems:
* changed local handler in Core/Assertions from private
to public, caused problems during compilation for
Georg Stemmer <stemmer(a)itc.it> on gcc version 3.2.2
20030222 (Red Hat Linux 3.2.2-5))
* fixed a small 64-bit linux compilation bug in
Fsa/Semiring.cc
I also apologize that the announcement of version 0.9.2 over a month ago
did not go to both mailing lists. All users that experienced compilation
problems due to Common C++ are strongly encouraged to try either version
0.9.2 or 0.9.3 as we removed the dependency on Common C++ from the package.
As usual, the package can be obtained from the software page at I6,
RWTH Aachen:
http://www-i6.informatik.rwth-aachen.de/web/Software/index.html
Cheers,
Stephan Kanthak
Dear,
First of all, I would like to say congratulation for
the new version of our FSA toolkit.
I have tried to compile the new version in my computer
but it seems not successful. As a very beginner of
Linux, I could not fix it myseft. Please help me to
solve the problem. Thanks in advance.
Bellow is the message appeared on the screen.

your problems are due to Common C++. It may be that
you didn't have it

please wait until
I've released the new version 0.9.2 which does not

Stephan,
Could you tell me when the new version of our FST
software is available ?
I am waiting for it for more than 2 weeks .

Fsa seemed to have no way of constructing the cross product of two
acceptors, so I wrote a function that would do it. I think I must
have handled the alphabets wrong, because when I concatenate such a
transducer with others, I get arcs with 2147483647 for the label.
Here's what I did:
crossProduct is a function that maps the output labels of the first
transducer and the input labels of the second transducer to epsilon,
and then composes them.
To map input labels and output labels to epsilon, I have two different
classes extending ModifyAutomaton:
EpsilonInputAutomaton replaces all of the arc input labels with
Epsilon, and returns an empty Alphabet from getInputAlphabet.
EpsilonOutputAutomaton does likewise with the outputs.
Is there something obviously wrong with this that should lead to
InvalidLabelId (which I think 2147483647 corresponds to) when I
concatenate a transducer produced using my crossProduct function?
Thanks,
Roy
