Hello, is it ok, that after the build process some of the source files have been changed and some other has been added?

Here there are some of the files that has been changed after build:: - Wireshark\epan\dfilter\grammar.c - Wireshark\epan\dfilter\scanner.c - wireshark\epan\diam_dict.c - wireshark\epan\dtd_grammar.c - wireshark\epan\dtd_parse.c - wireshark\epan\dtd_preparse.c - wireshark\epan\radius_dict.c - wireshark\epan\uat_load.c - etc

And here there are some of the files that has been generated after build: - wireshark\epan\inet_ntap.c - wireshark\epan\inet_ptap.c - wireshark\epan\mkstenp.c - wireshark\epan\strptime.c - wireshark\svnversion.h - wireshark\config.h

I am using Wireshark 0.99.7.

Thank you, Carlo

That version has been EOL'd for a very long time, so support will be mostly non-existent.

Are you building from a tarball, if so then it may include some generated files that get regenerated during the build?

Out of interest, why are you compiling such an old version?

Hello, and thank you!

Yes I am building from a tarball.
Reading your answer I get that it may include some generated files. So it is normal that these files can be regenerated during build, and some other can be generated from scratch.

My anxiety comes form the high number of differencies that I see, when I compare some of these files. For example. try to compare theese two files:
- diam_dict.c - https://drive.google.com/open?id=1E_q...
- diam_dict.rebuilt.c - https://drive.google.com/open?id=18v7...

Is it normal? Can I sleep pacefully? ;)

I am using Wireshark 0.99.7, because some years ago I have developed an ehercat voe dissector on that Wireshark version, that now I need to update in a very short time…

Thank you, Carlo

As nobody else is building that version now, we're relying on ancient memories, but I would expect everything is OK. The build from that version is what it is, so unless you've managed to obtain a trojan'ed tarball, I wouldn't worry about it.

I have done some regression test, respect Wireshark 0.99.7 + old dissector (buid with XP and VS2003).

I haven't seen differencies, using the regenerated Wireshark + regenerated dissector (build with W10 and VS2005). I have seen differencies, instead, using Wireshark 0.99.7 + regenerated dissector.

The dissector sources are the same. They have only been rebuilt with VS2005, instead of VS2003. Why I have this different behaviour?
