Comment 2 Richard W.M. Jones 2017-11-02 15:42:01 UTC

ocaml-libguestfs-devel is part of the libguestfs source package.

Unless we suspect that the OCaml compiler is at fault (which seems
very unlikely based on the description), this should have been filed
under libguestfs, and therefore I'm changing the component.  If it's
wrong for some reason please change it back with explanation.

Comment 5 YongkuiGuo 2017-11-03 03:47:04 UTC

Reproduced with the following packages:
binutils-2.27-19.base.el7.x86_64
libguestfs-1.36.10-1.el7.x86_64

Steps:

1. On rhel7.4(x86_64) host
#mkdir /dev/shm/delme; pushd /dev/shm/delme

2. Download the package of ocaml-libguestfs-devel-1.36.10-1.el7.x86_64.rpm
#rpm2cpio ocaml-libguestfs-devel-1.36.10-1.el7.x86_64.rpm | cpio -dim

3. #find . -type f -exec readelf -r -W {} \; > relocs.out

4. #grep -e GOTPCRELX -e GOT32X relocs.out

Comment 7 Richard W.M. Jones 2017-11-03 12:28:39 UTC

I verified that this appears to be fixed in the
ocaml-libguestfs-devel-1.36.10-2.el7.x86_64.rpm package.

Comment 8 YongkuiGuo 2017-11-06 03:04:40 UTC

Verified with the following packages:
binutils-2.27-19.base.el7.x86_64
libguestfs-1.36.10-1.el7.x86_64

Steps:

1. On rhel7.4(x86_64) host
#mkdir /dev/shm/delme; pushd /dev/shm/delme

2. Download the package of ocaml-libguestfs-devel-1.36.10-2.el7.x86_64.rpm
#rpm2cpio ocaml-libguestfs-devel-1.36.10-2.el7.x86_64.rpm | cpio -dim

3. #find . -type f -exec readelf -r -W {} \; > relocs.out

4. #grep -e GOTPCRELX -e GOT32X relocs.out

In step 4, there is no relocs found. So verified this bug.
