The error text in this case is You do not have support for any sources of high quality entropy enabled. For end user security, that is probably not what you want. Your options include: * Linux + glibc >=2.25 (getrandom): HAVE_GETRANDOM, * Linux + glibc <2.25 (syscall SYS_getrandom): HAVE_SYSCALL_GETRANDOM, * BSD / macOS >=10.7 (arc4random_buf): HAVE_ARC4RANDOM_BUF, * BSD / macOS <10.7 (arc4random): HAVE_ARC4RANDOM, * libbsd (arc4random_buf): If insist on not using any of these, bypass this error by defining XML_POOR_ENTROPY; you have been warned. If you have reasons to patch this detection code away or need changes to the build system, please open a bug. Thank you! You can bypass this by using CXXFLGS="-DXML_POOR_ENTROPY=1" but you should reinspect the osusres to use a better random seed. so long MUFTI _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
