Hello all, i have an areaDetector IOC which im cross-compiling for aarch64. The ioc also uses streamDevice 2.8.22 and is being compiled in an ubuntu 16.04 container.

I have another ubuntu 16.04 old container in which i compiled it in the past, but he configuration of the container is kinda messy and im improving things.

I remember i did something ugly in the old container and it has lpcre somewhere, but i couldnt find it, although i can recompile the ioc in it. I also couldnt solve the compilation issue in the new container with apt install libpcre3 libpcre3-dev or anything similar.

So in the new container i just found PROD_SYS_LIBS_DEFAULT += pcre in a makefile, commented it and it compiled nicely.

I understand its a lib for regex in perl and streamDevice might use it but might already have it out-of-the-box.

My question is: am i breaking my IOC in ways im going to regret? Or just getting rid of old dependencies that are not needed anymore? 

Thanks for any help, 

Marco
