The only way I know to get a TLS common symbol out of gcc is to use an omp pragma: int x; #pragma omp threadprivate (x) Otherwise TLS variables are generated as definitions rather than as common variables. Personally I tend to think that that is a good thing. Treating uninitialized variables as common variables is a non-standard extension even for C90. We can't get rid of them for existing code, but __thread code is by definition new. Why do you want them to be common? Ian
