    <p>I created a very simple C++ library in xcode, it was basically:</p> <pre><code>//Numbers.h class Numbers { public: int Get10(); } //Numbers.cpp int Numbers::Get10() { return 10; } </code></pre> <p>I compiled it to a static (debug) library then carefully followed <a href="http://monotouch.net/index.php?title=Documentation/Linking_Native_Libraries&amp;highlight=static%20library" rel="nofollow">the instructions here</a> up until step 2, I couldn't progress further because the code won't compile anymore, this is basically what the compiler outputs before giving me the 'mtouch failed with no output' message:</p> <blockquote> <p>/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 -arch i386 -gdwarf-2 -fobjc-legacy-dispatch -fobjc-abi-version=2 -miphoneos-version-min=4.3 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk /var/folders/-M/-Mb3Z8vAGIqK88qeV-fXk++++TI/-Tmp-/tmp216a96e0.tmp/main.x86.o -o /var/folders/-M/-Mb3Z8vAGIqK88qeV-fXk++++TI/-Tmp-/tmp216a96e0.tmp/ChicksnVixens -framework CFNetwork -framework Foundation -framework OpenGLES -framework UIKit -framework AudioToolbox -framework QuartzCore -framework CoreFoundation -framework CoreGraphics -framework AudioToolbox -lz -u _mono_pmip -u _CreateZStream -u _CloseZStream -u _Flush -u _ReadZStream -u _WriteZStream -liconv -lmono-2.0 -lmonotouch -L/Developer/MonoTouch/SDKs/MonoTouch.iphonesimulator.sdk/usr/lib -u _catch_exception_raise -L/Users/ahmedhakeem/Documents/Projects/goodjabberengine/MyCode/ChicksnVixens -lMylibrary -cxx -force_load /Users/ahmedhakeem/Documents/Projects/goodjabberengine/MyCode/ChicksnVixens/libLogger.a</p> </blockquote> <p>I very strongly suspect the compiler is not able to find libLogger.a because if I changed libLogger.a to something like abc.a (which doesn't exist) I get the same problem. I do know for sure that libLogger.a exists in the directory specified directory under MyCode/ChicksnVixens/ and it is included in the source hierarchy.</p> <p>Any ideas on how to fix this? I kind of suspect maybe it has something to do with me using xcode 4 to compile it?</p> <p>Or the problem could be the arguments I'm passing in:</p> <pre><code>-gcc_flags "-L${ProjectDir} -lMylibrary -cxx -force_load ${ProjectDir}/libLogger.a" </code></pre> <p>I had to add 'cxx' as per the instructions but maybe I'm doing something wrong without seeing it?</p>

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.
