Hi,
I have checked in your changes in the other mail.
I am still trying to battle with X509 and have made some progress. Thanks
for the feedback below.
The compiler can as i understand it not handle parameterized types so i
massaged the asn1 file to
not use parameterized types at all.
Now it then generates a pretty complete dissector (with dependencies on
other modules however)
but it will not compile.
The compiler has generated a ber_structure containing an undefined variable
imp
For example, see the structure : static ber_sequence
T_signedCertificate_sequence[] = {
The compiler also complains about the unknown define BER_UNI_TAG_UTCTime
in the generated file.
Please assist.

Hi Ronnie,
the "The same type names for different ..." warning is recommendation for
TYPE_RENAME
derective usage. See attached x509af.cnf file.
The "#Unhandled ..." message is internal compiler message which means that
something is
not supported and I have to implement it :-). But it is the better case of
unsupported
feature. Worse case is that it crashes with Python error :-(.
The "#Unhandled GetTTag() in SetOfType" was fixed with my patch which I sent
few minutes ago.
If you would like to understand a little bit an internal structure of the
compiler you can
use "-d t" option and redirect standard output. It will contain internal
tables of
compiler. (see attached file x509af)
Regards,
Tomas
