I replaced the -XR option with
and that works (ie, you are correct, -XR does not appear to pass the
sysroot to the linker) but there's another catch. Now I'm getting:
x86_64-linux-ld: skipping incompatible /mnt/engels/usr/lib64/libdl.so
when searching for -ldl
this library (on /mnt/engels) **is compatible** but it is a symlink:
/usr/lib64/libdl.so -> /lib/libdl.so.2
Given the specified --sysroot the linker should be looking at
but I'm guessing it's looking at
which does not right to me. It looks like --sysroot is not analogous to
chroot as far as the linker is concerned and symlinks are dereferenced
For completeness I added
as well, so all the (other) linker search paths are prepended with
/mnt/engels. This ended up producing a slightly errnoeous message:
x86_64-linux-ld: skipping incompatible /mnt/engels/usr/lib64
//libdl.so when searching for -ldl
Note the "//" in the reported path name before libdl.so.
This time it also reported the same error for glibc:
x86_64-linux-ld: skipping incompatible /mnt/engels/usr/lib64//libglib-
2.0.so when searching for -lglib-2.0
again with the erroneous "//".
This glibc library is also a symlink to the /lib directory on engels.
I tried adding -k-rpath-link options to tell the linker to look in the
relevant paths under /mnt/engels but all to no avail.
