building JPEG-8 with ALCHEMY

You need definitely need a "properly" installed Alchemy.

According to FlashLibJpeg on github,

Configure

LDFLAGS="-emit-llvm" CFLAGS="-emit-llvm" ./configure --prefix="$ALCHEMY_HOME/usr/local/" enable_shared="no" enable_static="yes"

Once youve configured, a make would generate jpeg.l.bc in ./.libs directory.

Thanks Ed!
