gcc undefined reference

gcc-problem-link library chain still exists "undefined reference to"? Description These days when performing some makefile found that the same link library link when the compile command, under different Linux platforms under different versions of GCC show different effects. Their code is the same, linked to the libra

GCC says: Undefined reference to 'std: cout' @ 10/17/2005Computing lifeThe program written by the boss should be run in Linux and Windows. As a result, I first wrote it through vs.net and then compiled it under GCC. This error occurs on N screens. I guarantee that my program is definitely a standard C ++ program. If

The online explanation is: "You need to add-lstdc++, or using ' g++ ' rather than ' gcc ' as your driver program." That is, if you want to use the g++ compiler, then you need to add "- Istdc++ ".I tried it, and when I added "-istdc++" to the link, there was no problem.About g++, reminds me, in Ubuntu the next beginning installs the Code::Blocks, the prompt needs installs the g++. Originally Code::Blocks built-in compiler used is the g++, but why in th

Because the pthread_create and Pthread_detach functions are not Linux's built-in functions, you need to add-pthread parameters to the link process when compiling a link production executable for a project that uses multithreaded technology. Depending on the help from the man in Linux, you can also see the corresponding hint "Compile and link With-pthread". So makefile should write this: testpthread:testpthread.o Gcc-o testpthread-pthread testpth

When using a thread, when compiling with GCC or ARM-LINUX-GCC, an error occurs: undefined reference to ' pthread_create 'There are two main reasons for this:1. #include 2,-lpthread compile options, that is, at compile time to add additional compilation options, such as the use of ARM-LINUX-

The undefined reference to ' sin ' error occurs when compiling a C program with a mathematical function using the GCC compiler. This error is generally caused by a lack of libraries.
