Re: [CMake] undefined reference to `_exit'

If I follow you correctly you are trying to replace the startup files that are normally used with your own versions. You don't mention what the new library is that you are using to replace the startup files. The standard startup files provide _init and _fini. You are also missing _exit which I

Re: [CMake] undefined reference to `_exit'

Hex, Can you see what else is in /opt/arm-none-eabi/lib/thumb/v7- ar/fpv3/hard (the same directory as libc.a)? There might be another system library that contains the _exit() implementation that isn't being linked due to your use of the -nostartfiles flag. Kyle On Fri, 2019-02-01 at 22:15 +,

I believe that doesn't have anything to do with C11 flags. You are just missing the link to the pthread library. I could be wrong. Try and add this to your cmake file: find_package (Threads) target_link_libraries (myexecutable/lib ${CMAKE_THREAD_LIBS_INIT}) Sent from my iPhone > On Feb 4,

Hello, I have a cmake project that uses C++11 threads. I have added the lines set (CMAKE_CXX_STANDARD 14) set(CMAKE_CXX_STANDARD_REQUIRED ON) CMAKE version is 3.2.2, running on Ubuntu. When I try to build, I get the error undefined reference to `pthread_create` Any ideas on how to fix this?

c++ does name mangling on functions... so functions like 'f' become a much more complex name (as shown in the xxx not found in your error messages). In order for C++ to not produce a mangled name C functions have to be defined as extern c void f( void ); but 'extern c' is not liked by C... so you
