We just posted v1.4rc2 on the web. It brings many additional fixes: + Fix missing last bit in hwloc_linux_get_thread_cpubind(). Thanks to Carolina Gómez-Tostón Gutiérrez for reporting the issue. + Fix FreeBSD build without cpuid support. + Fix several Windows build issues. + Fix inline keyword definition in public headers. + Fix dependencies in the embedded library. + Improve visibility support detection. Thanks to Dave Love for providing the patch. + Remove references to internal symbols in the tools.
Please test and let us know if you find any issue.
