    <p>I know this has been asked a thousands times, but I'm stumped. I've been looking all over for that last 3 days without a result. I keep getting this error and I can't figure out why. I've added only the code that I have input / that matters. If I comment out my code the program compiles without a problem. What am I doing wrong???</p> <blockquote> <p>CMakeFiles/brewtarget.dir/MainWindow.cpp.o: In function MainWindow::MainWindow(QWidget*)': MainWindow.cpp:(.text+0xb145): undefined reference to yeastCellCounter::yeastCellCounter()'</p> </blockquote> <p><strong><code>CODE</code></strong></p> <p><strong>mainwindow.cpp</strong></p> <pre><code>#include "yeastcellcounter.h" // a whole lot of stuff between these... yeastCountDialog = new yeastCellCounter(); </code></pre> <p><strong>mainwindow.h</strong></p> <pre><code>class yeastCellCounter; // A whole log of stuff between these... yeastCellCounter *yeastCountDialog; </code></pre> <p><strong>yeascellcounter.cpp</strong></p> <pre><code>#include "yeastcellcounter.h" yeastCellCounter::yeastCellCounter(){} </code></pre> <p><strong>yeastcellcounter.h</strong></p> <pre><code>#ifndef YEASTCELLCOUNTER_H #define YEASTCELLCOUNTER_H class yeastCellCounter { public: yeastCellCounter(); }; #endif // YEASTCELLCOUNTER_H </code></pre> <p>This are the INCLUDE_DIRECTORIES directive in cmakelist.txt</p> <pre><code>SET(ROOTDIR "${CMAKE_CURRENT_SOURCE_DIR}") SET(SRCDIR "${ROOTDIR}/src") SET(UIDIR "${ROOTDIR}/ui") SET(DATADIR "${ROOTDIR}/data") SET(TRANSLATIONSDIR "${ROOTDIR}/translations") SET(WINDIR "${ROOTDIR}/win") INCLUDE_DIRECTORIES(${SRCDIR}) INCLUDE_DIRECTORIES("${CMAKE_BINARY_DIR}/src") # In case of out-of-source build.

    2. CO@vinod I've made and edit to include the section that references the include_directories part in cmakelist.txt. It looks right to me, I added all my code the the same section as the rest of the source

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.
