Ubuntu 12.04 PPA fails compiling Expressions

Question

I am using Ubuntu 12.04, I recently updated via PPA to dolfin 1.2.0

My code does not work when I try to use "Expression"

In [1]: from dolfin import *
In [2]: mesh = UnitCubeMesh(10,10,10)
In [3]: V=FunctionSpace(mesh,"CG",2)
In [4]: E=Expression('x[0]>12?1:2')
Calling DOLFIN just-in-time (JIT) compiler, this may take some time.
In instant.recompile: The module did not compile with command 'cmake -DDEBUG=TRUE . ', see '/home/cchintaluri/.instant/error/dolfin_compile_code_d921ff1f9a69752d5ac5a72c2e599b20/compile.log'
.
.
In [5]: dolfin.__version__
Out[5]: '1.2.0'

In [6]: dolfin.has_cgal()
Out[6]: True

The complile.log reads thus:

CMake Error at CMakeLists.txt:11 (INCLUDE):
include called with wrong number of arguments. Include only takes one
file.

Thanks in advance!

Also including the CMakeLists.txt file as suggested by [Kent-Andre Mardal][1]

Compiling dolfin from the source solves the issue, perhaps this question / comment will address the issue with the PPA for Ubuntu 12.04.

Answer 1

Hi, perhaps the problem is related to spacing in your ternary operator. Try adjusting your
code following answers to this question.

Comments

Thank you for your comment. But it doesn't change the output

In [4]: a=dolfin.Expression('(x[0]>1) ? 1 : 2')

Calling DOLFIN just-in-time (JIT) compiler, this may take some time.
In instant.recompile: The module did not compile with command 'cmake -DDEBUG=TRUE . ', see '/home/cchintaluri/.instant/error/dolfin_compile_code_60df0b618f8bbad0294e27b48bbb6091/compile.log'

Answer 2

I think you need to send the CMakeLists.txt file as well.

Comments

Added the said relevant file. Thanks for the comment.

Compiling from the source resolves this issue. Perhaps an error in the PPA for Ubuntu12.04?

No, it is not an error in the PPA. I have tested it on several different setups and it works exactly as described in the answer in this question.
