Cef/Chromium Linker Issues on MAC

Hi All,

I somehow deleted my Cefclient Helper Target. When I decided to make helper target by making a duplicate of  Cefclient Target then faced some issues which are listed below along with their solutions that are quite generic and can be applied anywhere with similar issues.


System Info:
OSX : 10.11.6
XCode : 8.1

Error :

Undefined symbols for architecture x86_64 + "_main", referenced from: implicit entry/start for main executable

Solution :

• Main method is either commented or missing. Plz add
• int main(int argc, char * argv[])

Error :

 cef::logging::LogMessage::LogMessage(char const*, int, std::string*) in libcef_dll_wrapper.a(cef_logging.o)
      cef::logging::LogMessage::LogMessage(char const*, int, int, std::string*) in libcef_dll_wrapper.a(cef_logging.o)
      cef::logging::ErrnoLogMessage::~ErrnoLogMessage() in libcef_dll_wrapper.a(cef_logging.o)

libcef_dll_wrapper.a 

ld:symbol(s) not found for x86_64

Solution :

• C++ Standard Library: libc++ (LLVM C++ standard library with C++11 support)
• This value should be same for both Library and targets.
• In my case it was different for my Helper Target.
• Remember to set the correct architecture.

Hope its helpful :)
