gcc version if that helps...
g++ -v

We don't support PowerPC. Make sure you're using the correct GCC version.

[nareshk355]

could you please let me know which specific gcc version to use.

Hi Vitallium,

I am working with my colleague nareshk355 on this. We understand that phantomJS is not ported to PowerPC, but we are trying to port it ourselves to PowerPC. Once PhantomJS is ported to PowerPC, we will be committing it back to PhantomJS community.

We do have GCC ported to PowerPC, however if there is a need to port specific GCC version to PowerPC in order to get PhantomJS ported, we are willing to do that. Could you please let us know the specific GCC version you need to get PhantomJS compiled?

Any help in this regard is highly appreciated.

Thanks,
Atul.

@sowani It's not about a specific version of GCC, it's all about specific features on PowerPC (architecture).
In order to compile PhantomJS for your specific arch you need:

• Create mkspec for your platform (https://github.com/ariya/phantomjs/tree/master/src/qt/qtbase/mkspecs)
• Make sure Qt compiles successfully for it
• Webkit already has support for PowerPC, and it should be configured automatically, but you might need to adjust build flags.

I suggest you create a new issue where we can track support for PowerPC (like we did it for Solaris #10521)

[sowani]

Thank @vitallium! Yes, I think it would be better to create another issue to track PowerPC port, so we will create it now.

I understand that PhantomJS has dependency on Qt and Webkit and unless they are ported first, PhantomJS cannot be compiled on PowerPC. However, if it is not required for core functionality of PhantomJS, can it be somehow bypassed? This would enable us to work on core functionality first and tackle the Qt porting and support related functionality later.

Best regards,
Atul.

Closed. PowerPC is not supported target platform yet.
