    <h2>Background</h2> <p>I'm trying out Scons by setting up a basic C++ sample project that has two sub-projects:</p> <ul> <li>Prj1 is an EXE that depends on Prj2</li> <li>Prj2 is a DLL that exports some functions</li> </ul> <p>You can see the directory structure and the contents of my SConstruct and SConscript files <a href="https://stackoverflow.com/questions/279860/how-do-i-get-projects-to-place-their-build-output-into-the-same-directory-with">here</a></p> <h2>Problem</h2> <p>The problem I'm running into is that in order to build these targets from the command line I have to specify both the relative path to their build directory and their platform specific file extensions.</p> <p>For example, to build Prj1 I have to do:</p> <pre><code> build> scons ../bin/project1.exe </code></pre> <p>Likewise, to build Prj2 I have to do:</p> <pre><code> build> scons ../bin/project2.dll </code></pre> <h2>Question</h2> <p>How can I make SCons build these projects without specifying the relative path and platform specific file extension?</p> <p><strong>Desired:</strong></p> <pre><code> build> scons project1 build> scons project2 </code></pre> <h2>Potential Solutions</h2> <ul> <li>Use Alias - I'm pretty sure this <strong>is</strong> what I want but I'm messing something up apparently. I've tried the following without success:</li> </ul> <pre><code> prj1_env.Alias( 'project1', PROG) prj1_env.Alias( 'project1', os.path.join( BIN_DIR, PROG) ) </code></pre> <h2>References</h2> <ul> <li><a href="https://stackoverflow.com/questions/279860/how-do-i-get-projects-to-place-their-build-output-into-the-same-directory-with">How do I get projects to place their build output into the same directory with Scons?</a></li> </ul>

    1. COIf I remember from the other question PROG does not have the .exe on it. Try adding that in the second case.

    2. COThat is correct, PROG does not have the .exe on it. However, this is intentional and recommended by the Program function because adding the extension is platform specific and will therefore not support cross-platform work. I know I could put in platform detection, but SCons can do it for you.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
