Source: openmpi Followup-For: Bug #1120617 X-Debbugs-Cc: [email protected] User: [email protected] Usertags: hurd-amd64 Control: tags -1 ftbfs
Linux sets PATH_MAX to 4096 in /usr/include/linux/limits.h (included in sys/param.h) We already have a debian patch for hurd, so easy to update it to add 3rd-party/romio341/mpl/src/str/mpl_str.c. Updated build_hurd patch attached (patched against salsa debian/latest)
Description: Fix build problems on hurd-i386 This patch allows Open MPI to build on Debian GNU/HURD. . Also, the memory:linux MCA component is disabled, since its use of POSIX API in malloc hooks called very early at startup causes troubles. .
