* It is highly suggested to only enable the engines and features that you need for your test, e.g. <code>./configure --disable-gold --disable-detection-full --disable-all-engines --enable-engine=tinsel --disable-lua --disable-tinygl --disable-cloud --disable-hq-scalers --disable-optimizations --enable-debug</code> will save you a lot of time if you're only interested in testing the Tinsel engine. | * It is highly suggested to only enable the engines and features that you need for your test, e.g. <code>./configure --disable-gold --disable-detection-full --disable-all-engines --enable-engine=tinsel --disable-lua --disable-tinygl --disable-cloud --disable-hq-scalers --disable-optimizations --enable-debug</code> will save you a lot of time if you're only interested in testing the Tinsel engine. | ||
