PCRE2 support #444
Description
Hello,
Im new in c, c++ and I wanted to install snort3 with hyperscan support from source.
So I have debian bookworm and have to make some changes:
set (CMAKE_CXX_STANDARD 14) and CXX_FLAGS "-std=c++14". because of unique_ptr
set CXX_FLAGS -lpthread because of error with compilation
next wiht pcre, I did not install libhyperscan(which is old pcre.h lib) from default debian mirror.
I have to download old unofficial version of PCRE - none other available. So i did not like it.
So i downloaded latest PCRE2 source and rewrited the hyperscan to PCRE2.
for example pcre_exec, changed to pcre2_match|compile etc. with pcre2.h support and some castings things
The result is that the unit-hyperscan runs without errors but unit-chimera run with 35 errors. log is below:
maybe because of this:
https://stackoverflow.com/questions/70273084/regex-differences-between-pcre-and-pcre2
a) So I would like to ask you if the unit-hyperscan|chimera runs all tests OK. is it all valid?
b) And that 35 errors are due to new PCRE2 syntax? (32 errors is due to badpattern)
