Compiled w/o using artifacts ff is either super-slow or crashes? need help

Firefox Development
#1

hi!

i’m a newbie wannabe contributor, right now I am trying to do some simple customization, and have problems building FF

  1. the fast build with --enable-artifact-builds runs fine

  2. once i started changing some .cpp files, I needed to run a “real” compilation

compiled with --disable-optimize - to speed compilation up - ff runs, but is unusably slow: 3-5-10 second after each key press / click (is it normal?)

  1. compiled with optimization, it crashes on startup - shows a dialogue for sending crash report but doesn’t show stack trace or any error (“stack overflow” / “segmentation fault” etc.) it says it is “attempting” to generate dump, but the specified directory remains empty. can post crash report details if it can help

  2. compilation with --enable-release fails with “dist/include/mozilla/dom/AnimationEffectBinding.h:86:58: error: field has incomplete type ‘OwningUnrestrictedDoubleOrString’” (why is this only a problem with this build setting?)

i have almost zero experience building huge projects of compiled code, probably need some advice

thanks in advance for any help

Thank you for your desire to help Mozilla. As you probably noticed there isn’t much activity here. I suggest you join the Matrix and ask in the #introduction room.
