Wireshark-dev: Re: [Wireshark-dev] Solaris dfilter/dtd issues

Well, I have these:

firebird [~/]> flex -V
flex version 2.5.4
firebird [~/]> lex -V
lex: Software Generation Utilities (SGU) Solaris-ELF (4.0)
but it appears to be using 'flex':

checking for flex... /usr/local/bin/flex
I upgraded to flex 2.5.31 but still hit the problem.

So I updated SVN (to try the fix for bug 1010) and I still get the parse errors and the core:
firebird [~/wireshark/source/]> ./tshark -i qfe2
tshark: Dtd Parser in file /usr/local/share/wireshark/dtds/dc.dtd: syntax error in dc.dtd:7 at or before '#PCDATA': tshark: Dtd Parser in file /usr/local/share/wireshark/dtds/itunes.dtd: syntax error in itunes.dtd:7 at or before '#PCDATA': tshark: Dtd Parser in file /usr/local/share/wireshark/dtds/pocsettings.dtd: syntax error in pocsettings.dtd:4 at or before ')': tshark: Dtd Parser in file /usr/local/share/wireshark/dtds/presence.dtd: syntax error in presence.dtd:4 at or before ')': tshark: Dtd Parser in file /usr/local/share/wireshark/dtds/reginfo.dtd: syntax error in reginfo.dtd:5 at or before ')': tshark: Dtd Parser in file /usr/local/share/wireshark/dtds/rss.dtd: syntax error in rss.dtd:5 at or before ')': tshark: Dtd Parser in file /usr/local/share/wireshark/dtds/smil.dtd: syntax error in smil.dtd:14 at or before ',': syntax error at end of fileDTD parsing failure

firebird [~/wireshark/source/]> cat svnversion.h #define SVNVERSION "SVN Rev 18777"
though actually the core is in a new place:

Oof.

can you type
$ lex -V
$ flex -V

and see what comes out. I think you might be using sun's lex (for
which I never tested the code) instead of flex.

Hi list,

I've been trying to get a running Wireshark 0.99.2 on Solaris 9 for a
couple days now; recently I switched to working from SVN and I'm still
having issues.  They all seem to be related to dtd or dfilter stuff.
For example, trying to run SVN 18769 gives:

firebird [~/wireshark/source/]> export LD_LIBRARY_PATH=epan/.libs
firebird [~/wireshark/source/]> .libs/tshark -i qfe2

Magic num is 0x00000000, but should be 0xe9b00b9e

Interestingly, if I build the package and install it, I get a different
set of errors, still in dfilter, though:

The dtd errors make me think think maybe I'm running into issues at
least related to bug 1010:

http://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1010


Interestingly, if I create a ~/.wireshark/dtds, the error changes back
to the first one:

firebird [~/]> mkdir .wireshark

I've poked around with this for a while now and I'm not getting anywhere
fast.  Anyone have any clues/pointers?

Thanks,
