I started using Ubuntu on an older desktop. When I got this laptop (64 bit) I used the same CD to install Ubuntu (32-bit) on the laptop and never thought twice about it. As a result of your post I have now upgraded to Ubuntu 14.04 64-bit. Alas, I have the same problem compiling and linking the job. |

You might try getting verbose output from the linker by adding "-Wl,-v" to your compile command; it should tell you which directories it's searching for libraries. These will be directories will be prefixed by "-L". If libdevIl.so (or libdevIl.a) is in a directory that the linker isn't searching, you'll probably have to add your own -L<directory name> to the compile command. Louis |

I was thinking it might have to do with the OP's assuming int is 4 bytes.

Scroll down. This was already covered in the part you erased before replying: Compilation attempt with g++ gives these errors: %g++ -Wall -std=c++11 program.cpp -o program.exe weird-program.cpp: In function 'int main()': weird-program.cpp:16:7: error: 'make_unique' is not a member of 'std' std::make_unique<std::string> ("string"); ^ weird-program.cpp:16:35: error: expected primary-expression before '>' token std::make_unique<std::string> ("string"); ^ weird-program.cpp:18:30: error: request for member 'find' in '("examples")', which is of non-class type 'const char [9]' std::cout << ("examples").find('x') << std::endl; ^ Hmmm. Function "make_unique" *should* be in header <memory>. Ah, I see, I'm compiling with std=c++11, but I need std=c++14. <<< HERE Then you need to rethink your usage of "find" a if it were a method of a string literal. String literals don't have methods. But std::string does, so i'll make that correction for you. Yes, THIS version compiles: #include <initializer_list> #include <iostream> #include <ostream> #include <string> #include <regex> #include <thread> #include <memory> void alpha() { std::cout << "alpha\n"; } int main(void) { std::unique_ptr<std::string> s = std::make_unique<std::string>("string"); std::regex pat {R"(\w{2}\s*\d{5}(-\d{4})?)"}; std::cout << std::string("examples").find('x') << std::endl; std::thread t(alpha); t.join(); return 0; } %g++ -Wall -std=c++14 program.cpp -o program.exe [no errors, no warnings] On running, prints: 1 alpha -- Cheers, Robbie Hatley Midway City, CA, USA perl -le 'print "\154o\156e\167o\154f\100w\145ll\56c\157m"' http://www.well.com/user/lonewolf/ https://www.facebook.com/robbie.hatley |
