Hi Nicholas,
I am also compiling ClamAV into a library and opening it with a dlopen()
call. The technique I use is:
/configure
make
I then merge together the different ClamAV libs using this command:
ld -shared -o clamav.lib clamav-0.94.2/libclamav/.libs/libclamav.a
clamav-0.94.2/libclamunrar_iface/.libs/libclamunrar_iface.a
clamav-0.94.2/libclamunrar/.libs/libclamunrar.a -lbz2 -lgmp -lpthread -lz
Which creates a file called clamav.lib that can be passed to dlopen().
There are a couple of notes. Which libraries you dynamically link
against when using ld will vary depending on your platform and how
ClamAV configures itself. For example, on my system I don't actually
link against pthread specifically because I know the program I'm using
is already linked against the pthread library. On Cent OS 4/Red Hat
Enterprise 4 specifically, I need to pass the --disable-zlib-vcheck
parameter to configure and I need to manually edit the libclamav
makefiles to pass -O1 instead of -O2 to gcc or all of the free() calls
will be optimized away inside the cl_free() function. See this bug for
details:
https://bugzilla.redhat.com/show_bug.cgi?id=490253
If anyone knows of a better way to do this, or finds any problems with
using ClamAV this way, please let me know...
