[Scons-users] TeX, PDF, VariantDir + children() and "no such file or directory: '.sconsign.dblite'"

[Pawel Tomulik]

Hi,

I have a simple project with three files:

SConstruct
src/SConscript
src/foo.tex

It uses VariantDir and DVI + PDF builders to compile LaTeX document. The
contents of the files are:

# SConsctruct
env = Environment(tools = ['latex','dvipdf'])
VariantDir('build', 'src', duplicate = 1)
SConscript('build/SConscript', exports = 'env')


# src/SConscript
Import('env')
dvi = env.DVI('foo.tex')
pdf = env.PDF(dvi)
print str(pdf[0].children()) # <- the pdf[0].children() causes the error


# src/foo.tex
\documentclass{article}
\title{Hello world}
\author{Pawel Tomulik}
\date{April 2013}
\begin{document}
   \maketitle
   Hello world!
\end{document}

When compiling the project, I get exception
  OSError: [Errno 2] No such file or directory: '.sconsign.dblite':

Here is the full log from build:

After compilation I have .sconsign.tmp file in my top source directory, 
but there is no .sconsign.dblite.

My setup is: debian jessie/sid, python2.7, scons 2.3.

SCons by Steven Knight et al.:
         script: v2.3.0, 2013/03/03 09:48:35, by garyo on reepicheep
         engine: v2.3.0, 2013/03/03 09:48:35, by garyo on reepicheep
         engine path: ['/usr/lib/scons/SCons']


Is this a bug or its me doing something wrong? Any workaround?

I attach a minimal example.

Regards!
