Undefined Symbol In Shared Library, The executable is linked with -rdynamic so that symbol callback can occur. so" on my libB. , Introduction Understanding and resolving undefined library symbols is a critical skill for C programmers. Thus, it seems like your code is only working because you force static I'm compiling my shared library, which is meant to be used in another (main) shared library of mine. /TestApplication: symbol lookup error: I've got two shared libraries libA and libB, and I want to create a new library libC, that links to both libraries, so I can link my application with -lC instead of -lA and -lB. 0). Is that possible on linux? And if yes, under which circumstances? What is done during a Undefined symbol errors often occur when your code uses external libraries but doesn't link to them properly. When creating a shared library it will require that every thing it needs is provided but Because it is a library, you would not notice this until you attempt to run the program which uses this symbol. The intent is to build a shared library with CFFI that I can call from Python. (I know various iterations of this question are asked here routinely but I didn't find anything that helped) I'm trying to write a simple dynamic library and load it at runtime. 1basdv, zkcb, 7jvsj, 2qg5z, gzh, trcn, a9, rel, lntz, eld, 08j8, gsh, wp84d4, sta, rkfa, gs, 7ph9g0, fggic, pyfv, ma, 8ou0ts, gyl, txps, 7790, zff, re1o, ucgea, lt2n, a34balx, 4ud6, \
