Can't compile v8ppc with nativesim=true for PowerPC 440

[sokovykh]

Hi All,

I want to compile v8 in simulation mode, but I get strange errors:

Can I build nodejs with some "nativesim=true" option for build V8 engine in simulation mode?

Hi,
You should be able to use the official google v8 repo (https://chromium.googlesource.com/v8/v8.git) to build V8 on ppc. Google V8 4.5 and up contains all the PPC changes.

You may encounter an error with gclient sync, although MAKE should still work, but you can fix that issue by disabling sysroot check for ppc. More info https://github.com/ibmruntimes/v8/issues/1 (we are in process of upstreaming this change)

@jbajwa

Thanks, I tried:

gclient config --spec "solutions = [{'name': 'v8', 'url': 'https://chromium.googlesource.com/v8/v8.git'}]"
gclient sync
make nativesim=true ppc.debug V=1 -j8 snapshot=off

But I get the following errors:

Hi,
The make command is missing "i18nsupport=off" option (since we don't have internationalization support on Big-Endian platform yet)
However, that option won't fix the errors you are seeing, looks like g++ is not correctly configured, the include path is not set correctly.
Can you try compiling this in verbose mode

>cat test.cpp
#include <ostream>
int main() {return 0;}

>g++ test.cpp -v

-v should emit the include path that gcc uses to lookup the header files.

Hi,
I think my crosscompiler powerpc-440-linux-gnu-g++ is configured correctly, because I can build other big projects. For example (node-v4.4.7 from https://nodejs.org/dist/v4.4.7/node-v4.4.7.tar.gz)

I can to compile successfully your example:

Just a clarification on the internationalization front. Its not that it is not supported in V8 for BE but that the tests are not set up to properly test as they have LE dependencies. Regardless to be able to get a clean test run you do need to disable it as @jbajwa mentioned

[sokovykh]

@jbajwa @mhdawson
Thanks for clarification! But I can compile V8 (without snapshot and i18n, in BE and define USE_SIMULATOR in globals.h) only as part of nodejs (v.4.4.7 or 6.3.2) see issue #128.

Why I can't compile separate last version of v8?

[jbajwa]

@zZzlodey
Hi,
If you're seeing the same error as before eg:"fatal error: 'ostream' file not found", that looks like gcc not being able to find the key header files, which has nothing to do with v8.
You can try the following:

make -j1 SHELL="/bin/bash -x" ...

It should print the failing g++ command, and you can run that separately with "-v" to see why gcc is not able to find for those headers.

Also, without i18nsupport=off V8 should build fine, but to get a clean test run you need it disabled. (we are in process of enabling it #109 )

Hi, You should be able to use the official google v8 repo (https://chromium.googlesource.com/v8/v8.git) to build V8 on ppc. Google V8 4.5 and up contains all the PPC changes.

You may encounter an error with gclient sync, although MAKE should still work, but you can fix that issue by disabling sysroot check for ppc. More info https://github.com/ibmruntimes/v8/issues/1 (we are in process of upstreaming this change)

@jbajwa Is it still relevant? We don’t need v8ppc branch, upstream has ppc code? I am interested to build v8 for Darwin PowerPC (and bring it to Macports then hopefully).
