Suricata

If Suri is compiled towards a custom PCRE 8.38 "/opt/pcre" location on Debian Jessie .. during the configure stage - it still disables/blacklists PCRE jit since it finds that the one in the OS is 8.35 ...but it should not complain since it is pointed to a diff location where the pcre version is diff/better than 8.35.

Configure line -

./autogen.sh && ./configure  --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-pie --enable-geoip  --enable-lua --with-libpcre-includes=/opt/pcre/include/ --with-libpcre-libraries=/opt/pcre/lib/   --with-libjansson-includes=/usr/local/include/ --with-libjansson-libraries=/usr/local/lib/ --with-libnss-libraries=/usr/lib64 --with-libnss-includes=/usr/include/nss3 --with-libnspr-libraries=/usr/lib64 --with-libnspr-includes=/usr/include/nspr4

where pcre is compiled and installed in /opt/pcre - with the following config line -

./configure --prefix=/opt/pcre/ --enable-unicode-properties --enable-jit --enable-utf8 --enable-pcre16 --enable-pcre32--enable-pcregrep-libz --disable-static  && make clean && make -j && make install
