It would therefore be good to add the relevant architecture dependencies in Config.in, and probably only the ones you actually tested. For example, it's not necessarily clear if the MIPS support covers MIPS 32 bits only, or also MIPS 64 bits, and if it covers MIPS 64 bits, which MIPS ABIs are supported. Also, that's a minor nit, but you could use some 'else' instructions, like: ifeq (...) ... else ifeq (...) ... else ifeq (...) ... endif > +define LJSYSCALL_INSTALL_TARGET_CMDS > + $(INSTALL) -d $(TARGET_DIR)/usr/share/luajit-$(LUAJIT_VERSION)/syscall > + $(INSTALL) -m 0644 -t $(TARGET_DIR)/usr/share/luajit-$(LUAJIT_VERSION)/ $(@D)/syscall.lua > + $(INSTALL) -m 0644 -t $(TARGET_DIR)/usr/share/luajit-$(LUAJIT_VERSION)/syscall $(@D)/syscall/*.lua > + > + $(INSTALL) -d $(TARGET_DIR)/usr/share/luajit-$(LUAJIT_VERSION)/syscall/linux/$(LJSYSCALL_ARCH) > + $(INSTALL) -m 0644 -t $(TARGET_DIR)/usr/share/luajit-$(LUAJIT_VERSION)/syscall/linux/ $(@D)/syscall/linux/*.lua > + $(INSTALL) -m 0644 -t $(TARGET_DIR)/usr/share/luajit-$(LUAJIT_VERSION)/syscall/linux/$(LJSYSCALL_ARCH) $(@D)/syscall/linux/$(LJSYSCALL_ARCH)/*.lua > +endef Maybe you could define: LJSYSCALL_TARGET_DIR = $(TARGET_DIR)/usr/share/luajit-$(LUAJIT_VERSION) and use that in your install target commands to save a bit of space. Could you fix these and resend an updated version? Thanks! Thomas

It's true, and this was also suggested by François. However, the limitations are already in LuaJIT, except even more restrictive, so he relented on the suggestion. But i can certainly do that. I'm not sure about the MIPS cases either, and I notice that LuaJIT avoids MIPS altogether. So I'll follow that example. > Also, that's a minor nit, but you could use some 'else' instructions, > like: > > ifeq (...) > ... > else ifeq (...) > ... > else ifeq (...) > ... > endif Wow, I didn't know that Make could do that.

An FFI implementation of the Linux and NetBSD kernel ABIs for LuaJIT. Signed-off-by: Danomi Manchego <danomimanchego123@gmail.com> --- Note: this package requires LuaJIT specifically, so there is a depends-on in the ljsyscall/Config.in, even though though it is included from a menu with a "if BR2_PACKAGE_LUA || BR2_PACKAGE_LUAJIT" test around it. v1 -> v2: Removed unnecessary build time dependency on LuaJIT. Specify -m 0644 during installation, since .lua files need not be executable. --- package/Config.in | 1 + package/ljsyscall/Config.in | 8 ++++++++ package/ljsyscall/ljsyscall.mk | 35 +++++++++++++++++++++++++++++++++++ 3 files changed, 44 insertions(+) create mode 100644 package/ljsyscall/Config.in create mode 100644 package/ljsyscall/ljsyscall.mk
