[Buildroot] Enable option of nodeJS 4.1.2 in buildroot 2015.11

[Buildroot] Enable option of nodeJS 4.1.2 in buildroot 2015.11

[Lijun QIN]

Hello Buildroot supporter,

I have Buildroot 2015.11 with some Marvell flavor.
According to Mavell's instructions, I did
(1) make mvebu_armv7_le_defconfig
(2) select external toolchain gcc5.2-HF
(3) I run make menuconfig, trying to select Node.JS 4.1.2 package in
Interpreter languages and scripting selection, but only node.JS 0.10.40 is
available.
(4)  However,  I tried to make raspberrypi2_defconfig,  make menuconfig
does offer options to
      select Node.JS 4.1.2.
 Could you please possibly provide any advice on fix ? I post some part of
my .config file
Thank you so much.

That's because nodejs 4.1.2 on Buildroot 2015.11 (and 6.7.0 on current master) 
depends on BR2_ARM_CPU_HAS_VFPV2:

config BR2_PACKAGE_NODEJS_V8_ARCH_SUPPORTS
        bool
        # On supported architectures other than ARM, no special requirement
        default y if !BR2_arm
        # On ARM, at least ARMv6+ with VFPv2+ is needed
        default y if !BR2_ARM_CPU_ARMV5 && BR2_ARM_CPU_HAS_VFPV2

The comment seems indicates that BR2_ARM_CPU_HAS_VFPV3 should also be fine. 
You may try changing this line to

        default y if !BR2_ARM_CPU_ARMV5 && (BR2_ARM_CPU_HAS_VFPV2 || BR2_ARM_CPU_HAS_VFPV3)

Yann, you added this dependency in commit f443386c5d. Is that the right fix?

[Buildroot] Fwd: Enable option of nodeJS 4.1.2 in buildroot 2015.11

[Lijun QIN]

Thank you so much for your help, Baruch
I took your advice and applied the change to the Config.in in nodejs
package. Since my .config does not have BR2_ARM_CPU_HAS_VFPV3,  I used
BR2_ARM_CPU_MAYBE_HAS_VFPV3 instead. The issue seems to have fixed.
Thank you so much again, Baruch.

That's because nodejs 4.1.2 on Buildroot 2015.11 (and 6.7.0 on current
master)
depends on BR2_ARM_CPU_HAS_VFPV2:

config BR2_PACKAGE_NODEJS_V8_ARCH_SUPPORTS
        bool
        # On supported architectures other than ARM, no special requirement
        default y if !BR2_arm
        # On ARM, at least ARMv6+ with VFPv2+ is needed
        default y if !BR2_ARM_CPU_ARMV5 && BR2_ARM_CPU_HAS_VFPV2

The comment seems indicates that BR2_ARM_CPU_HAS_VFPV3 should also be fine.
You may try changing this line to

        default y if !BR2_ARM_CPU_ARMV5 && (BR2_ARM_CPU_HAS_VFPV2 ||
BR2_ARM_CPU_HAS_VFPV3)

Yann, you added this dependency in commit f443386c5d. Is that the right fix?

I'm wondering if BR2_ARM_CPU_HAS_VFPV3 shouldn't select
BR2_ARM_CPU_HAS_VFPV2, and ditto for V4 selecting V3.

Not really: if VFPv3 is enabled, so is VFPv2, see the conditions:
	https://git.buildroot.org/buildroot/tree/arch/Config.in.arm#n21

and see the reasons below...

Unless I'm mistaken, that's already the case, and has been so at least
since 2013:

    5f959a1c arch: improve ARM floating point support and add support for EABIhf

   21 config BR2_ARM_CPU_HAS_VFPV3

[Buildroot] Fwd: Enable option of nodeJS 4.1.2 in buildroot 2015.11

Lijun, All,

This is definitely incorrect. The _MAYBE_HAS option is an internal one
that should not be used to derive the presence of abscence of VFPv3.

If your CPU does have VFPv3, then you must enable it with the correct
option, BR2_ARM_ENABLE_VFP "Enable VFP extension support", which has
been avaialble since f52692e: arch/arm: add option to enable an optional
VFP unit (and I should know, I did that patch in 2015! ;-) ).

Please update your Buidlroot version.

Sorry, this is the support for the official Buildroot. If you have
troubles with a fork from some vendors, we can't really help: we have no
way to know what has been changed in your tree.

Please use the latest released version of Buildroot, and you'll even get
nodejs 6.7.0 for the rpi2.

I don't see how I could miss this. But then, why did Lijun had issues
selecting NodeJS, and Baruch proposal to add || BR2_ARM_CPU_HAS_VFPV3
solved it?

We need to look into this.

It did _not_ solve the issue, because Lijun did not have BR2_ARM_ENABLE_VFP
enabled, which meant he also did not have BR2_ARM_CPU_HAS_VFPV3 enabled.

Instead, he did use BR2_ARM_CPU_MAYBE_HAS_VFPV3 which is wrong.

Lijun must enable BR2_ARM_ENABLE_VFP in his config, if his CPU (cortex-a9)
indeed has a VFP. If not, then he'll be stuck with nodejs 0.10.x and
there is nothing we can do about that.

Nothing to investigate here on our side.

Yann E. MORIN.

Actually Lijun had to add BR2_ARM_CPU_MAYBE_HAS_VFPV3. That's apparently 
because 2015.11 predated Yann's commit f52692ed64c64 (arch/arm: add option to 
enable an optional VFP unit). So BR2_ARM_CPU_HAS_VFPV3 was not selected and 
hence neither BR2_ARM_CPU_HAS_VFPV2.
