Hi.

I'm trying to install the latest version of clamav (0.102.3) on Ubuntu 20.04. I'm configuring clamav following the steps explained in http://www.clamav.net/documents/installation-on-debian-and-ubuntu-linux-distributions. It's the first time that I download the source code and I configure and compile a programme. I'm blocked because I don't know how to recompile with fPIC.

The two last steps:

configure: Summary of detected features follows

              OS          : linux-gnu

              pthreads    : yes (-lpthread)

configure: Summary of miscellaneous features

              check       : -lcheck_pic -pthread -lrt -lm -lsubunit

              fanotify    : yes

              fdpassing   : 1

              IPv6        : yes

              openssl     : /usr

              libcurl     : /usr

configure: Summary of optional tools

              clamdtop    : yes (-lncurses)

              milter      : no (missing libmilter) (disabled)

              clamsubmit  : yes (libjson-c-dev found at /usr, linking=static)

              clamonacc   : yes (auto)

configure: Summary of engine performance features

              release mode: yes

              llvm        : no (disabled)

              mempool     : yes

configure: Summary of engine detection features

              iconv       : yes

              bzip2       : ok

              zlib        : yes (from system)

              unrar       : yes

              preclass    : yes (libjson-c-dev found at /usr, linking=static)

              pcre        : /usr

              libmspack   : yes (Internal)

              libxml2     : yes, from /usr

              yara        : yes

              fts         : yes (libc)

             

I think it's all right. Then, I try to compile:

(...)

Those are the last messages. I have to recompile with -fPIC, but I don't know how. I've spent some hours trying to find the way to do it, but... Can you help me? Thank you very much.
