Thus this warning is rather bogus apparently. Would > you please file a bug report against dpkg-dev for this? If you don't actually use threads, the stubs provided by glibc will be used (they are mostly no-ops). This is done to avoid the need for every library to come in a single-threaded and a multi-threaded version and yet pay the performance costs of threading only when they are actually needed. The only such function you use is pthread_exit(), so dpkg-shlibdeps is correct here. -- 1KB // Microsoft corollary to Hanlon's razor: // Never attribute to stupidity what can be // adequately explained by malice.
