NodeJS on linux-ppc64be (T1040D4RDB)

I need to get a working copy of node 8 on the T1040. I am using the Qoriq SDK v2.0 and have tried meta-node but the binary produced crashes on start. Cross compiling does not really work, but compiling from source on the T1040 and executing gets a little farther, but crashes in the V8 engine.

The team that supports the nodejs ppc port is from IBM, and they do not support Freescale/NXP ppc64 hardware. The support is almost there as they support linux-ppc64le and AIX-ppc64be, so I hope to add support for a linux-ppc64be target.

Building the node 8.11.4 release binary succeeds and node starts, but it crashes after any input (like enter).

$ ./configure --without-intl --without-snapshot --gdb --without-inspector
$ make -j4 node
./node
>
unhandled signal 4 at 000000bb709be26c nip 000000bb709be26c lr 000000bb708b39f0 code 30001
# .... ENDS IN SIG 4 (illegal instruction).....‍‍‍‍‍‍‍‍‍‍‍‍

Building with the debug configuration and running with gdb shows that the initial crash is in the native macro assembly module:

$ ./configure --without-intl --without-snapshot --gdb --without-inspector
$ make -j4 -C ./out BUILDTYPE=Debug node
$ gdb ./out/Debug/node

This crash is from a debug assertion in some template code that is removed in later versions of v8, I am removing the assertion and recompiling to see if the crash still happens.

I appreciate any assistance or direction with this problem. I do not have much experience with porting and can use some suggestions for tools or techniques.

Hello Patrick Brown,

Please download the latest nodejs 7.10.0 recipe from OpenEmbedded Layer Index - meta-nodejs, then put these recipes in the folder meta-openembedded/meta-oe/recipes-devtools/nodejs, and execute "bitbake nodejs".

Please add "nodejs" in variable IMAGE_INSTALL_append in meta-freescale/recipes-fsl/images/fsl-image-core.bb, execute "bitbake fsl-image-core" to build nodejs to the rootfs filesystem.

Have a great day,
TIC
