Build Issues

[Corey]

Hey, so I'm coming back to an old project of mine that I'm starting up again, and I'm trying to build V8 from scratch on the r9343 revision, and I'm getting some errors when trying to build. I'm using Visual Studio 2010 on Windows 7 x64, building as x86 using the following:

C:\path\to\v8> "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" x86

C:\path\to\v8> scons mode=debug library=shared env="PATH:%PATH%,LIB:%LIB%,INCLUDE:%INCLUDE%"

All goes well until the linking phase, where I get these errors:

v8preparser_g.dll : fatal error LNK1120: 8 unresolved externals

scons: *** [v8preparser_g.dll] Error 1120

scons: building terminated because of errors.

I've looked through the compilation instructions for Windows several times, and haven't found anything to indicate why I would be getting this problem.

Hi Corey,

sorry for the late reply. The shared library build seems indeed to be
broken. However, it seems to work fine if you provide a target to
scons, for example the d8 shell:

scons mode=debug library=shared env="PATH:%PATH%,LIB:%LIB%,INCLUDE:

%INCLUDE%" d8

As the scons build is going to become deprecated in the medium term, I
would like to point you to the GYP build: http://code.google.com/p/v8/wiki/BuildingWithGYP

Regards,

Yang

Hm, well I'm trying to run the GYP install in cygwin, and I get this:

I'm sure my cygwin is missing some modules, I'm just not sure what.
