Hello,

 

I have been trying to build streamdevice with PCRE but cannot for the life of me figure out why the compilation keeps failing (using libpcre and libpcre-dev). The release file for streamdevice has PCRE_LIB=/usr/lib  and PCRE_INCLUDE=/usr/include/pcre which seem to be pointing to the correct libraries.  I have looked into trying to build PCRE as a standalone epics module as well as stated in the documentation but ran into similar issues using PCRE v8 and v10 from the ftp(didn’t see v7 which is what the documentation originally built with for standalone).  It looks like one of the pcre shared objects is failing to compile and recommends to compile with -fPIC flag but it looks like that flag is already being used.  Couldn’t find a ton of info out on the internet with regards to this type of compilation error except that usually the -fPIC (position independent code) fixes it.  Below is my compilation error
