    <p>My goal is to successfully link a folder to /opt/ directory- which needs to be run with sudo.</p> <p>I have tried this:</p> <pre><code> system(sudo ln -s $$OUT_PWD/xampp /opt/lampp):message("You should manually link LAMPP") </code></pre> <p>But building from qt-creator it does not prompt for sudo password, therefore I couldn't get it to link the folder. I got the "wrong password attempts..." error in the Compiler Output. Then I tried these with build steps:</p> <pre><code>make sudo make install </code></pre> <p>to see if it would prompt me there, but it failed on <code>make install</code> step with the same error, which is this in detail:</p> <pre><code>00:31:20: Starting: "/usr/bin/sudo" make install sudo: no tty present and no askpass program specified sudo: no tty present and no askpass program specified Sorry, try again. sudo: no tty present and no askpass program specified sudo: no tty present and no askpass program specified Sorry, try again. sudo: no tty present and no askpass program specified sudo: no tty present and no askpass program specified Sorry, try again. sudo: 3 incorrect password attempts 00:31:20: The process "/usr/bin/sudo" exited with code 1. </code></pre> <p>The <code>system()</code> function in the qmake script works fine when I use <code>qmake &amp;&amp; make &amp;&amp; make install</code> from terminal since it prompts me before <code>sudo ln...</code> command; but for fast testing purposes I feel that building with CTRL-B inside Qt Creator should also work with sudo commands... </p> <p>Is there a way to be prompted from Qt Creator, or a way around this? Like storing the sudo pass within the Qt Creator (although it is risky)... Or maybe making it run build steps on a terminal where it would prompt me? Would <code>prompt()</code> function in qmake work with gathering sudo passwords?</p> <p>Any suggestions are welcome...</p>

    1. COCan you build from gnome-terminal? I'm not sure how you would integrate a build step in Qt-Creator that requires elevated privileges. It would probably be easier to build from the terminal anyway. You could easily make a bash script that does all the build steps including qmake, make, and make install.

    2. COYes, I can build from gnome-terminal. Thank you for the suggestion, I was thinking that a bash script would be easier too... :)

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.
