Using the system LLVM</A>

</H2>

Some problems have been reported when compiling ClamAV's built-in LLVM with recent
|
|
C++ compiler releases. These problems may be avoided by installing and using
|
|
an external LLVM system library. To configure ClamAV to use LLVM that is installed
|
|
as a system library instead of the built-in LLVM JIT, use following:
|
|
<PRE>
|
|
$ ./configure --with-system-llvm=/myllvm/bin/llvm-config
|
|
$ make
|
|
$ sudo make install
|
|
</PRE>
|
|
The argument to <code>--with-system-llvm</code> is optional, indicating the path name of
|
|
the LLVM configuration utility (llvm-config). With no argument to <code>--with-system-llvm</code>,
|
|
<code>./configure</code> will search for LLVM in /usr/local/ and then /usr.
|
|
|
|

|
|

|
|
Recommended versions of LLVM are 3.2, 3.3, 3.4, 3.5, and 3.6. Some installations have
|
|
reported problems using earlier LLVM versions. Versions of LLVM beyond 3.6 are not
|
|
currently supported in ClamAV.
