copied!<p>I figured out what the problem is when I was trying to see why the print statement I suggested in the comments didnt work.</p> <p>First of all, an efficient way in Python to print all the strings in a list of strings is like this:</p> <pre><code>', '.join(Sources) </code></pre> <p>The part in the quotes <code>', '</code> is the separator between elements in the list of strings.</p> <p>I realized the problem with the following SConstruct excerpt:</p> <pre><code>sources = (Glob('src/dir1/*.cc') +Glob('src/dir2/*.cc') +Glob('src/dir3/*.cc')) print sources print ', '.join(sources) </code></pre> <p>Which gives this output:</p> <pre><code>scons: Reading SConscript files ... [<SCons.Node.FS.File object at 0x122e4d0>, <SCons.Node.FS.File object at 0x122e710>, <SCons.Node.FS.File object at 0x122e950>] TypeError: sequence item 0: expected string, File found: File "/home/notroot/projects/sandbox/SconsGlob/SConstruct", line 10: print ', '.join(sources) </code></pre> <p>That's when I remembered that the SCons Glob() function returns a list of Nodes (Files), not a list of strings. According to the <a href="http://www.scons.org/doc/production/HTML/scons-man.html" rel="nofollow">SCons man page</a> (search for 'glob(' ) the usage is as follows:</p> <pre><code>Glob(pattern, [ondisk, source, strings]) </code></pre> <p>And the strings argument does the following:</p> <blockquote> <p>The strings argument may be set to True (or any equivalent value) to have the Glob() function return strings, not Nodes, that represent the matched files or directories...</p> </blockquote> <p>The MSVSProject() builder is expecting a list of strings, not Nodes. So, it works as you are expecting if you do the following:</p> <pre><code>sources = (Glob('src/dir1/*.cc', strings=True) +Glob('src/dir2/*.cc', strings=True) +Glob('src/dir3/*.cc', strings=True)) print ', '.join(sources) </code></pre> <p>Which gives the following output:</p> <pre><code>scons: Reading SConscript files ... src/dir1/main.cc, src/dir2/func2.cc, src/dir3/func3.cc scons: done reading SConscript files. scons: Building targets ... scons: `.' is up to date. scons: done building targets. </code></pre>
