I'm upgrading my project to use Cocoapods and when I try building my project for an iOS device or for a simulator I get: Undefined symbols for architecture armv7: "_OBJC_CLASS_$_TestFlight", referenced from: objc-class-ref in PhotoPreviewViewController.o "_OBJC_CLASS_$_Flurry", referenced from: objc-class-ref in MyAppDelegate.o objc-class-ref in InitialSetupViewController.o objc-class-ref in InitialDownloadViewController.o objc-class-ref in HistoryViewController.o ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am porting an old vc++6.0 application to vs2005, I am getting the following linker error and I have spent days trying to find a solution. error LNK2019: unresolved external symbol _ imp _CreateAwnService@52 referenced in function "public: int __thiscall CMainFrame::CreateAsaNetworkServices(void)" There is a 3rd party C library with the following API defined extern "C" { DLLAPI IAwnServ * AWNAPI CreateAwnService(HINSTANCE hInst, const char *pszDId, const char *pszDLoc, AWN_DIQUAL DiQual, AWN_DOQUAL DoQual, int Prio, const char *pszLicStr, const char *pszInfo, AWN_REPEAT Repeat=R_LAST, TIME_T

This question already has an answer here: initialize array with constant number does not work 2 answers I'm having an issue with my neural net. I'm storing the nodes that make up the network in an array, whose dimensions are set via-tweaks at compile time (the tweaks are all const). The code worked fine until I decided to split it up into multiple files, but even with a extern declaration, it still says that "array bound is not an integer constant before ']' token". Right now, this is the set-up: In Network.h: struct Network { Node nodes [MNETWIDTH] [MNETLENGTH]; } In Network.cpp: Network:

I have to compile PJSIP in CPP compiler. Because I am integrating an API with PJSIP . It is in CPP . So I have to use g++ instead of gcc . But now I didn't integrate any other API. But I am getting linker error in CPP compiler. If it is C compiler, it is working fine.

I've already read gdb says "cannot open shared object file" and gdb can not open shared object file and followed the instructions. I have a binary which is linked to a shared library file ( /zzz/yyy/xxx.so ). After I set LD_LIBRARY_PATH to /zzz/yyy/ and run the binary without GDB, it executes very well. However, when I was trying to use GDB to debug this binary, GDB says: error while loading shared libraries: xxx.so: cannot open shared object file: No such file or directory I already have (set in .gdbinit): (gdb)show env LD_LIBRARY_PATH LD_LIBRARY_PATH = "/zzz/yyy/" and (gdb) show solib-search
