If by "platform" you mean hardware platform, I can't really speak to that. The next paragraph sort of insinuates that you mean OS-platform. In that case, it doesn't matter, since the entire block of code in question is enclosed in: print '#if defined(GLX_USE_TLS) && defined(__linux__)' > As you say, I'd guess it's hard to find a *Linux* system w/o TLS > support.

With all due respect, asking nVidia and all of the other GL vendors to start implementing this tag is a little unrealistic. nVidia also seems to deal with the TLS solution somehow, since they used to have "tls" copies of their libraries installed, and I believe now ship them exclusively. I think the non-TLS days are long behind us. Can anyone else comment? What is the purpose of the ABI tag? If it were removed and someone tried on kernel 2.4.18, would the actual behaviour be any different or result in the same segfault anyway? --Pat ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
