The Cray compiler wrappers will often add `-lrt` to the base compiler with `-static` linking (the default at most sites.) However, `-lrt` isn't automatically added with `-dynamic`. This means that if jemalloc was built with `-static`, but then used in a program with `-dynamic` jemalloc won't have detected that librt is a dependency. The integration and stress tests use -dynamic, which is causing undefined references to clock_gettime(). This just adds an extra check for librt (ignoring the autoconf cache) with `-dynamic` thrown. It also stops filtering librt from the integration tests. With this `make check` passes for: - PrgEnv-gnu - PrgEnv-intel - PrgEnv-pgi PrgEnv-cray still needs more work (will be in a separate patch.)
jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling, Valgrind integration, and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: http://www.canonware.com/jemalloc/
