Hello,
I'm attempting to port an application to FreeBSD (version 10 to be
specific). The application has been developed using C++11 and uses
thread_local.
As below, the use of thread_local is giving me linking errors for the C++
ABI.
troy@freebsd10:~ # cat tl.cpp
#include <string>
thread_local std::string test;
int main()
{
}
troy@freebsd10:~ # clang++ -std=c++11 tl.cpp -o tl
/tmp/tl-7sN7Nb.o: In function `__cxx_global_var_init':
tl.cpp:(.text+0xbb): undefined reference to `__cxa_thread_atexit'
clang++: error: linker command failed with exit code 1 (use -v to see
invocation)
troy@freebsd10:~ #
Has anyone else experienced this? Should I report it as a bug?
Thanks,
Troy Heron
