Build failure: cannot allocate an object of abstract type error

[GoogleCodeExporter]

I'm running the following as instructed:
svn checkout http://v8.googlecode.com/svn/trunk/ v8
svn checkout http://pyv8.googlecode.com/svn/trunk/ pyv8
export V8_HOME=/home/user/v8
cd pyv8
python setup.py build

The build fails during the pyv8 part (v8 itself builds just fine):

I'm using a flavor of ubuntu 12.10 with python 2.7.3.

What's causing this issue?

This issue is being caused by the current revision of v8.  The workaround to 
fix this problem is to checkout r13134 of v8.  Additionally, make sure to 
comment out line 448 in pyv8/setup.py so that pyv8 does not update the v8 code:
#self.checkout_v8()

I've got the same problem. In order to build PyV8, I follow this guide: 
http://andrewwilkinson.wordpress.com/2012/01/23/integrating-python-and-javascrip
t-with-pyv8/ I've checkedout the r13134 of v8, as you suggested here, but it 
doesn't work! Any suggestions?

Did you comment out self.checkout_v8() ? If not, then you will update v8 to the 
new non-working version before building pyv8.

Original comment by rsimmo...@gmail.com on 8 Dec 2012 at 6:24

[GoogleCodeExporter]

Yes, I've commented self.checkout_v8() in setup.py (in pyv8 source code).

Original comment by gilberto...@gmail.com on 8 Dec 2012 at 6:28

[GoogleCodeExporter]

Ah.  Perhaps don't follow those directions.  Do the following:
svn checkout http://v8.googlecode.com/svn/trunk/@13134 v8
svn checkout http://pyv8.googlecode.com/svn/trunk/ pyv8
Comment out line 448 of pyv8/setup.py: #self.checkout_v8()
export V8_HOME=/path/to/v8
cd pyv8
python setup.py build
sudo python setup.py install

Now it works. I suppose the error was in "export PyV8=`pwd`" command. Thank you 
for helping me.

I just attempted to build today and experienced this issue.  The easiest 
solution I found, given the current v8 code base is to have setup.py checkout 
r13261 of v8.  If you set V8_SVN_REVISION to 13261, everything seems to work 
just fine.

It looks like r13262 was a fairly large change, and the most recent culprit for 
these errors.

• Changed state: Accepted

[GoogleCodeExporter]

Why does pyv8 require its own private copy of v8 to build against?  Can't it be 
set to build against an installed version of v8 already on the system?

[GoogleCodeExporter]

v8 disabled C++ exception and RTTI by default, but boost::python need it

Please verify it with SVN trunk code after r459, thanks

I've just been able to build successfully on Mac OS.  Thanks for the fix!
