# Using dynamic linked lua is not recommended for performance

# reasons. http://article.gmane.org/gmane.comp.lang.lua.general/18519
|
|
|
|
# Mainly, this is of concern if your arch is poor with GPRs, like x86.
|

# Therefore both lua interpreter and compiler are statically linked to
|
|

|
# the core library modules.

# Note: This patch only adds the required targets to the makefiles
|
|
|
|
# instead of relying upon libtool, which fails cross-compiling. Both
|
|
|
|
# shared and static versions of lua libraries are installed.
