Debugging shared libraries
To debug the libraries that are built by the build tool you will have to make a few changes to the build configuration. For libraries built outside the build environment you will have to do some extra work.
The Yocto Project
The Yocto Project builds debug variants of binary packages and puts them into build/tmp/deploy/<package manager>/<target architecture>. Here is an example of the debug package, for the C library in this case:
build/tmp/deploy/rpm/armv5e/libc6-dbg-2.21-r0.armv5e.rpm
You can add these debug packages selectively to your target image by adding <package name-dbg> to your target recipe. For glibc, the package is named glibc-dbg. Alternatively, you can simply tell the Yocto Project to install all debug packages by adding dbg-pkgs to EXTRA_IMAGE_FEATURES. Be warned that this will increase the size of the target image dramatically, perhaps by several hundred megabytes.
The Yocto Project places the debug symbols in a hidden directory named...
