    <p>I know a similar question to this has already been asked but I have been unable to fix this issue for hours.</p> <p>Basically I have a DLL with code in it and an application that calls it. Everything works fine but if I take the two outside of my development enviroment it says the program cannot start because <code>libgcc_s_dw2 1.dll</code> is missing from the computer. </p> <p>This is fair enough considering it is not a development computer. So for distribution I added the compiler flags "<code>-static-libgcc -static-libstdc++</code>". I did this for the dll and for the application.</p> <p>But when I compile the application I get the error:</p> <blockquote> <p>"multiple definition of `_Unwind_Resume'"</p> </blockquote> <p>I thought this was due to both the dll and the application having the static libraries built into them, and it is. But if both of them don't have the static libraries built in, the program will not run on end user machines.</p> <p>How can I remove this error while still having no dependencies on the mingw libs? My IDE is Code::Blocks.</p> <p>David</p> <p><strong>EDIT:</strong> here is the build log when building the application that links to the dll:</p> <pre><code>c:/mingw/bin/../lib/gcc/mingw32/4.6.2/libgcc_eh.a(unwind-dw2.o):(.text+0x298c): multiple definition of `_Unwind_Resume' ..\EquilibriumEngine\bin\Release\libEquilibriumEngine.dll.a(d000015.o):(.text+0x0): first defined here collect2: ld returned 1 exit status Process terminated with status 1 (0 minutes, 0 seconds) 2 errors, 0 warnings </code></pre>

    1. COCan you add whatever log Code::Blocks has for the build (something that includes the commands used to compile/link along with whatever warnings and errors result)?

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.
