10:42 <olek_poz> Hello guys. While I'm learning crystal I started working on http rest api server https://github.com/akwiatkowski/crystal_api Hope it will become useful in future

13:51 <xdougx> hello :)

13:52 <xdougx> when i have an processes running in a pid xyz and then i have a method called when this process is running, and this method starts another process, it will block the current process?

16:29 <SergXIIIth> Hello. I would like bind to libav (ffmpeg). I have building problems, same program on C pass build. More details in https://gist.github.com/SergXIIIth/c5d6bcac4476ac09c0f8

16:46 <jhass> looks like you ran into https://github.com/manastech/crystal/issues/1269

16:47 <jhass> https://github.com/zamith/heroku-buildpack-crystal/pull/2/files might give a workaround

17:09 <SergXIIIth> Hm... Does not help. Here output - /usr/bin/ld: /opt/crystal/embedded/lib/libgc.a(os_dep.o): undefined reference to symbol '_end'

17:14 <SergXIIIth> Other problem is build crystal from source. msa@Mag2 ~/oss/crystal (master)

17:14 <SergXIIIth> $ make

17:14 <SergXIIIth> CRYSTAL_CONFIG_PATH=`pwd`/src ./bin/crystal build -o .build/crystal src/compiler/crystal.cr

17:14 <SergXIIIth> I wait for a day, but command it still running :-(

17:16 <jhass> oO

17:17 <jhass> it shouldn't take more than 10min on a recent enough machine

17:24 <SergXIIIth> it look like it not work at all. I believe this process - 18542 msa 20 0 21004 2716 2552 S 33.1 0.1 3:38.27 bash /home/msa/oss/crystal/bin/crystal build -o .build/crystal src/compiler/+
