[GitHub] [trafficserver] Bharat786 opened a new issue #8222: Error using lpeg.so with trafficserver.
Bharat786 opened a new issue #8222:
URL: https://github.com/apache/trafficserver/issues/8222
I build trafficserver version 9.0.2 from the source code and since luajit (LuaJIT 2.1.0-beta3) was installed, it was able to generate tslua.so plugin and then i installed lpeg using luarocks, but when i ran trafficserver it is showing this error :
```

actually you do have https://github.com/luvit/lpeg/blob/master/makefile
you can try out changing
"DLLFLAGS = -shared -fPIC"
and add " -lluajit-5.1" to the end and then use "make linux" to compile and see.

That should be because the lpeg.so is compiled to expect the lua related symbols in the executing context. In a normal lua program, those should be expected to be present. In ATS, they are not and you will need to compile your shared object to require a dynamic link to the luajit library.
