A recent post on C++11 lambdas and a forum question led me to this topic. Lambdas are a new C++ feature, described very well in the first link. The forum post asked how to build a simple test program using lambdas with ellcc:
#include <functional> #include <iostream> #include <string> int main(int argc, char **argv){ std::string test; test += "Hello World!"; std::cout << test << std::endl; auto lambda = [&](const std::string &in) -> void { std::cout << "Text was: " << in << std::endl; return; }; lambda("extra text."); return 0; }
The simple solution was:
[~] dev% ellcc/bin/ecc++ -target x86_64-ellcc-linux --std=c++11 test.cpp [~] dev% ./a.out Hello World! Text was: extra text. [~] dev%
The important thing here is that you need the -target option to set the appropriate target environment and you need to specify --std=c++11 to enable C++11 language features.
