  1. POLinking Static Libraries in iPhone SDK 3.0
    text
    copied!<p>I have an iPhone app that heavily relies on the OpenCV library; as such, I've compiled a static version of this library for inclusion with my app. The instructions for doing this are relatively straightforward: <a href="http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en" rel="nofollow noreferrer">Using OpenCV on iPhone</a>. The only gotcha I ran into was setting the linker flag, <code>STANDARD_C_PLUS_PLUS_LIBRARY_TYPE</code> to "<code>standard</code>". The app compiled and ran perfectly under OS 2.0 and 2.2.</p> <p>After upgrading to SDK 3.0 and trying to re-compile my app, I'm running into an issue with this linker flag. I'm getting this error while linking:</p> <p><em>ld: library not found for -lstdc++-static</em></p> <p>It's also interesting that on my system, "libstdc++-static" is present under seemingly every iPhoneOS and iPhoneSimulator SDK except for iPhoneOS.platform/SDKs/iPhoneOS3.0.sk. Here are the search results:</p> <pre><code>$ locate libstdc++-static /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/usr/lib/libstdc++-static.a /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/lib/libstdc++-static.a /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/usr/lib/libstdc++-static.a /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.sdk/usr/lib/libstdc++-static.a /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.0.sdk/usr/lib/libstdc++-static.a /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.1.sdk/usr/lib/libstdc++-static.a /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.2.1.sdk/usr/lib/libstdc++-static.a /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.2.sdk/usr/lib/libstdc++-static.a /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/usr/lib/libstdc++-static.a /Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libstdc++-static.a /Developer/SDKs/MacOSX10.5.sdk/usr/lib/libstdc++-static.a /usr/lib/libstdc++-static.a </code></pre> <p>I'm pretty baffled and haven't been able to find any answers on Google or iPhone dev forums. I'd really appreciate if someone could shed some light here.</p> <p>Thanks!</p>
