Cross compiling V8 for ARM on Windows

[Mihail Slavchev]

Hello,

I am trying to compile V8 for ARM using cygwin and ndk-r9. I get the following error:

  CXX(host) /home/slavchev/test/node/deps/v8/out/android_arm.release/obj.host/v8_base.arm/src/platform-posix.o

  CXX(host) /home/slavchev/test/node/deps/v8/out/android_arm.release/obj.host/v8_base.arm/src/platform-linux.o

/tmp/cchi7mgX.s: Assembler messages:

I tried setting different arm architectures as follows

export CCFLAGS="-march=armv5"

and 

export CCFLAGS="-march=armv7"

but it didn't help.

My GYP knowledge is very poor and I am looking for a guide/article how to compile V8 for ARM on Windows. Any help is appreciated.

Thanks,

Mihail

Hi Rodolph,

Thank you for the quick response. I've read the suggested wiki and http://code.google.com/p/v8/wiki/D8OnAndroid as well but I couldn't find any info about cross compiling V8 for ARM on Windows. There is info about cross compiling V8 for ARM on Linux, though. Unfortunately, this is not my scenario.

I start to think that cross compiling V8 for ARM on Windows is not supported option, though I don't see any reasons for this. I guess I am missing something.

I've never heard of anyone trying to cross-compile V8 for ARM on Windows. I have no idea if it is possible. You're welcome to try it, and contribute patches and/or documentation if/when you find out anything.
