Re: [Clamav-devel] enabling DMG and XAR support

Why do people have to be so stupid and immediately implicate the build tools or environment?
Because updates and bug-fixes were applied, your assuming that these are not done correctly or in compliance with the OS and build environment or that they are faulty. 


First, you need to stop this bull-crap about non-standard and heavily  
modified and listen to the details regarding the issue you are told  
and stop focusing on the build tools which you have no clue about.



It is best that you accept my word that it is standard and in  
compliance with the OS, build environment and ADE.



I have confirmed the issue still exists under gcc-4.4 so it's not a  
build tool issue.



I now have generated a fully working  ClamAV 0.98.1 under gcc-3.3,  
gcc-4.0.0 and gcc 4.0.1 by cleanly autoreconf-ing the source tree.



Here's my configure for the working builds under the mentioned  
compilers:
CFLAGS="-arch ppc -arch i386 -g -Os -pipe -DFD_SETSIZE=2048 -arch ppc  
-arch i386" CCFLAGS="-arch ppc -arch i386 -g -Os -pipe " CXXFLAGS="- 
arch ppc -arch i386 -g -Os -pipe " LDFLAGS="-arch ppc -arch i386    
"   ./configure --prefix="/usr" --mandir=/usr/share/man --sysconfdir=/ 
etc --enable-bigstack --with-user=clamav --with-group=clamav --with- 
dbdir=/var/clamav --disable-clamav





Is using ltmain.sh from Debian-Ubuntu called portability amongst  
different environments??

Your entire build system is non-standard if you maintain in the way  
you say

you do.


This is very likely an architecture issue and will require explicit  
casts
in order to work for you (which would cause performance decreases  
for every
other ClamAV user). Would you expect the ClamAV project to maintain  
this?
You say you have submitted code in the past, you will likely need  
to make

this work yourself by adding the explicit casts to the codebase.


This really isn't an issue with ClamAV or LLVM/Clang. You have a  
system

that is relatively unsupportable because of A) age and B) you have

*heavily* modified it at this point to attempt to maintain it. Even  
if one
of us had an old PPC with gcc 4.0 (which compiles ClamAV just fine  
on FC4

which makes me think your patching has not been as successful as you

think), we would still not have the same environment you do since  
you claim

to maintain your binaries by hand.


Unless you are willing to add the explicit casts yourself, I think  
you are

probably SOL.

make

make install # no issues with the build or install but nothing

works and segfaults (expected behavior)

Legacy systems are unfortunate. However, I think you would be hard
pressed to find any open source project today supporting that, so I

don't think it is that ridiculous to not expend the effort to  
actively

support it. I wouldn't be surprised if the code required to make it

compile on your system *and* modern systems caused performance  
decreases

(or even not compile on modern gcc!).


There might be a small chance that you would need to maintain a  
separate
patchset to maintain this compatibility since having it compile  
on both
your legacy and modern systems would be detrimental to other  
ClamAV users.
