Off-topic post but we use McAfee with MIMEDefang so hopefully people won't
mind. And since McAfee is end of lifing the 4400 product at the end of
January, others might benefit.
In short, we have some older but perfectly good boxes running that we want
to upgrade with the Linux version of McAfee (Uvscan). However, the current
version (5100) no longer is compiled where it will work on machines without
GCC 3.2.
This means that on older machines that predate GCC 3.2, it won't work. It
also means that on newer machines like CentOS 4, you have to load
compat-libstdc++-33-3.2.3-47.3 RPMs because GCC 3.2.3 was released in
2002/2003 so it's already outdated, sigh.
ldd uvscan
liblnxfv.so.4 => /usr/local/lib/liblnxfv.so.4 (0x40018000)
libstdc++.so.5 => not found
libm.so.6 => /lib/libm.so.6 (0x4046a000)
libgcc_s.so.1 => not found
libc.so.6 => /lib/libc.so.6 (0x4048d000)
libdl.so.2 => /lib/libdl.so.2 (0x405cc000)
libstdc++-libc6.2-2.so.3 => /usr/lib/libstdc++-libc6.2-2.so.3
(0x405d1000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
What I've done is downloaded the source to GCC 3.2.3 and run the following
commands:
./configure --prefix=/usr/local/gcc3.2.3
make install
vi /etc/ld.so.conf adding /usr/local/gcc3.2.3/lib as the last entry?
ldconfig
This seems to work fine.

Since I have virtually no experience compiling compilers and stdc libs, I've
got the following questions:
a) will this cause issues with other programs on the server?
b) is there a better way to compile gcc (perhaps gcc core?) where you just
get the libgcc_s.so.1 & libstdc++.so.5?
Love to hear from anyone else dealing with this issue out there or who has
any experience with libstdc / gcc issues.
Regards,
KAM
