    <p>I know there are several questions regarding this. I have looked through them all but still haven't found an answer.</p> <p>I'm trying to use SDL with xCode on my Mac. I'm using xCode 4.5</p> <p>I followed <a href="http://lazyfoo.net/SDL_tutorials/lesson01/mac/xcode/index.php" rel="nofollow">this</a> tutorial exactly, twice! I even tried a second tutorial which was basically the same and it still didnt compile.</p> <p>When i compile i get this error:</p> <pre><code>Ld /Users/shardy/Library/Developer/Xcode/DerivedData/SDL_SetUp-efqnmqdzqqtkktbodsopeytuwjxt/Build/Products/Debug/SDL_SetUp normal x86_64 cd "/Users/shardy/Desktop/shardy/C++ Programs/GlutApps/SDL_SetUp" setenv MACOSX_DEPLOYMENT_TARGET 10.7 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ -arch x86_64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk -L/Users/shardy/Library/Developer/Xcode/DerivedData/SDL_SetUp-efqnmqdzqqtkktbodsopeytuwjxt/Build/Products/Debug -F/Users/shardy/Library/Developer/Xcode/DerivedData/SDL_SetUp-efqnmqdzqqtkktbodsopeytuwjxt/Build/Products/Debug -F/Library/Frameworks -filelist /Users/shardy/Library/Developer/Xcode/DerivedData/SDL_SetUp-efqnmqdzqqtkktbodsopeytuwjxt/Build/Intermediates/SDL_SetUp.build/Debug/SDL_SetUp.build/Objects-normal/x86_64/SDL_SetUp.LinkFileList -mmacosx-version-min=10.7 -stdlib=libc++ -framework SDL -framework Cocoa -o /Users/shardy/Library/Developer/Xcode/DerivedData/SDL_SetUp-efqnmqdzqqtkktbodsopeytuwjxt/Build/Products/Debug/SDL_SetUp Undefined symbols for architecture x86_64: "_main", referenced from: start in crt1.10.6.o (maybe you meant: _SDL_main) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) </code></pre> <p>Followed by:</p> <pre><code> "_main", referenced from: Start in crt1.10.6.o (maybe you meant:_SDL_main) Symbol(s) not found for architecture x86_64 Linker command failed with exit code 1 (use -v to see invocation) </code></pre> <p>I was originally using xCode 4.3 and it wouldnt compile, so i updated to xCode to 4.5 thinking maybe xCode was causing issues and tried everything again, but unfortunately, still did not compile... I am not experienced enough to know how to fix this and i am out of relatable threads to read... Thanks.</p>

You should update your question to say what you tried, but didn't work so other people don't give you answers that you've already tried. The error message is telling you the linker can't find a main() function. Assuming you have a main() function in your program, check its arguments. You may also need to add a search path to the SDL headers to the Header Search Paths build setting, which you can see in Step 6 of the LazyFoo tutorial you linked to.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
