I am trying to compile freeradius on uclibc, it complains of undefined symbol __tls_get_addr. So I went to modify src/include/autoconf.h, and commented #define HAVE_THREAD_TLS 1, then the compilation was successful. My question is what do I missed from disabling THREAD_TLS ? Does it mean performance impact ? Will it mean freeradius will be slower, consuming more memory or what ?

Apparently src/lib/log.c is the only source which uses HAVE_THREAD_TLS, and from the source I can see that once I disable HAVE_THREAD_TLS, in my case, the code will be USE_PTHREAD_FOR_TLS. Sorry this sounds like something for the developer folks but it remains as a user question:- What is the performance impact of disabling THREAD_TLS but USE_PTHREAD_FOR_TLS instead ? Thank you for your attention.
