Compilation of nanojit with avmplus generates errors on arm32 linux

[al-sabr]

Greetings to all!

I was since the last 2 days trying to compile avmplus which incorporates nanojit. I had to modify the configure.py files and use py-cpuinfo to get detailed infos about the cpu and the features supported by the host cpu.

py-cpuinfo : https://github.com/workhorsy/py-cpuinfo avmplus : https://github.com/adobe/avmplus

This is a fork of avmplus on my github repo : https://github.com/gdeverlant/avmplus

Now these are the information concerning the arm32(armv7l) board I'm using to compile natively: more info here : http://www.hardkernel.com/main/products/prdt_info.php?g_code=G141578608433

* Amlogic ARM® Cortex®-A5(ARMv7) 1.5Ghz quad core CPUs 
* Mali™-450 MP2 GPU (OpenGL ES 2.0/1.1 enabled for Linux and Android)
* 1Gbyte DDR3 SDRAM
* Gigabit Ethernet
* 40pin GPIOs
* eMMC4.5 HS200 Flash Storage slot / UHS-1 SDR50 MicroSD Card slot
* USB 2.0 Host x 4, USB OTG x 1,
* Infrared(IR) Receiver

This is the output I get from py-cpuinfo:

    "bits": 32,

    "hz_advertised_raw": [

        0
    ]
}

I'm running on HypriotOS (Debian Jessie) armhfv7(ARM32) via SSH. I had to remove the GCC error flag in configure.py file https://github.com/gdeverlant/avmplus/blob/arm32/configure.py#L139.

When I tried to compile the the project I got this error at the end with nanojit:

true "Compiling nanojit/njconfig"

make: *** [nanojit/NativeARM.o] Error 1

I have no idea what does it mean can someone help me to overcome this problem?

Hi - sorry I am unable to help with avmplus questions. Also my version of NanoJIT is only tested on x64.

[al-sabr]

nanojit is actually a part of avmplus. It is the only part which gives me error. We can maybe collaborate and check what are the possibilities.

Hope you had some luck with this. Unfortunately I don't think I can help as the problem is not something I can test.
