No. ldd output from a cmake on a different system and architecture
(amd64):
libdl.so.2 => /lib64/libdl.so.2 (0x00000039e1e00000)
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x0000003332800000)
libm.so.6 => /lib64/libm.so.6 (0x00000038a1e00000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00000039e3a00000)
libc.so.6 => /lib64/libc.so.6 (0x00000039e1600000)
/lib64/ld-linux-x86-64.so.2 (0x00000039e1200000)
Oddly enough, I cannot get anything from this binary within the chroot,
outside of the chroot or even on a Linux system:
not a dynamic executable
strace does show it loading dynamic libraries:
open("/etc/ld.so.cache", O_RDONLY) = 3
open("/lib/libdl.so.2", O_RDONLY) = 3
open("/usr/lib/libstdc++.so.5", O_RDONLY) = 3
open("/lib/libm.so.6", O_RDONLY) = 3
open("/lib/libgcc_s.so.1", O_RDONLY) = 3
open("/lib/libc.so.6", O_RDONLY) = 3
Heh. I tried to rebuild the RPM within the chroot, but it also cores
during the build.
