Bug ID: 8916
Summary: LDFLAGS pass to openssh
Product: buildroot
Version: unspecified
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: yxygyxyg at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---
The fail message we obtain in buildroot-compiled chroot environment:
bash-4.3# ssh
bash: /usr/bin/ssh: No such file or directory
It happens because ssh execute file does not contain proper dynamic linker way:
# readelf /tmp/usr/bin/ssh -l
...
[Requesting program interpreter:
/home/cf/e2k/mcst.rel-21-0.fs/2016-04-12/e2k-generic-linux.cross/lib64/ld-linux.so.2]
...
The proper way to dynamic linker we set with
BR2_TARGET_LDFLAGS="-Wl,-dynamic-linker,/lib/ld-linux.so.2" option in .config
file. This scheme works fine in different packages (busybox, bash ...).
In case of openssh package the option does not pass through
package/openssh/openssh.mk file:
...
OPENSSH_CONF_ENV = LD="$(TARGET_CC)" LDFLAGS="$(TARGET_CFLAGS)"
...
Here internal openssh option LDFLAGS contain only common $(TARGET_CFLAGS).
Common $(TARGET_LDFLAGS) does not pass inside openssh build system here.
If we change this line to the next:
...
OPENSSH_CONF_ENV = LD="$(TARGET_CC)" LDFLAGS="$(TARGET_CFLAGS)
$(TARGET_LDFLAGS)"
...
ssh works fine.
