This only occurs if you just do -lpthread. This can be worked around in the build, by changing -lpthread to -lpthread -lrt so I don't think it is a ship stopper but its something that should likely be fixed at some point. I am currently poking at this. 86898 1 jpuhlman 2020-04-03 05:18:08 +0000 Adding Tim, since he did a lot of work on this and may have some insight. 86904 2 jpuhlman 2020-04-03 16:51:59 +0000 Here is the issue: 3061991 openat(AT_FDCWD, "/home/jpuhlman/builds/master/profiles/opencgx-x86-generic-64/buildtools/sysroots/x86_64-pokysdk-linux/etc/etc/ld.so.conf", O_RDONLY) = -1 ENOENT (No such file or directory) 86905 3 jpuhlman 2020-04-03 17:39:17 +0000 Looks like the issue is ld_sysconfigdir is set to /<sysroot path>/ then we add /etc/ld.so.conf as well in the binutils ld patch.
