[ptxdist] Newbie: Howto add luajit 2.x as a new package in ptxdist

[ptxdist] Newbie: Howto add luajit 2.x as a new package in ptxdist

[Michael Deiters]

Hi,

I'm a newbie on ptxdist. I successfully managed to build my 1st BSP based 
on Generic-arm recently.

I'm getting lost on how to add luajit including the libluajit-5.1-dev as 
package to ptxdist. I understand the approach to add an autotoolized 
package, but for the desired luajit-5.1-dev, I can only find the apt-get 
source on my host.

I'm wondering if there isn't an easy way to let ptxdisk know about the 
required package. I searched the web, but didn't found enlightenment...

I would be grateful if somebody could point me the right direction.

Many thanks in advance!

Kind regards
Michael

Hi Michael,

there is no need to add a -dev package for luajit, at least not for 
installing on the target. When crosscompiling, the install stage of your 
rules/luajit.make effectively calls `make install` in the luajit source 
folder, which should install the development headers to 
<your-platform>/sysroot-target/. When other packages depend on luajit, 
they will look there for the includes and libraries to link against.

What is installed into the target root file system is different from 
that; your `targetinstall` stage is responsible for that and should copy 
all the files needed on the target to <your-platform>/root (e.g. by 
using $(call install_lib), $(call install_alternative) etc., see Section 
5.2 in the PTXdist manual [1]).

Hope that helps!

  - Roland

Hi Roland,

many thanks for the swift reply.

My disconnect starts already at the first stage. My BSP has no information 
that I need luajit in my project. I understand I need to create the 
"rules" files to instruct PTXdist to compile luajit. My question is, how 
do the rule file(s) look like, if I (simply) would like to include a 
source package from a debian distro. I'm afraid I'm either far away from 
the correct approach or very close...

Thank you for your patience.

Kind regards
Michael

Hi Michael,

Have a look at the manual that Roland linked in his answer:
http://www.pengutronix.de/software/ptxdist/appnotes/OSELAS.BSP-Pengutronix-Generic-arm-Quickstart.pdf

Specifically chapter 4, PTXdist Developer’s Manual, and section 4.2,
Adding new Packages.

Best regards,

Guillermo

Hi Michael,

LuaJIT is not Autotools-based and cross-compilation is complicated:
According to the Makefile, you can only cross-compile from 64-bit host
systems to 32-bit target systems with multilib-libraries. (gcc -m32)
But maybe it's enough to advise the user in the HELP text, that he needs
to have multilib libraries installed on his host system..

You have to pass custom variables in LUAJIT_MAKE_ENV.

Also have a look at Buildroot, how they did it:
https://github.com/buildroot/buildroot/blob/master/package/luajit

Cheers,
Clemens
