Bug ID: 12076
Summary: Patchelf can link against an incompatible libc++
version
Product: buildroot
Version: 2019.05.1
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: bradley.gamble at ncipher.com
CC: buildroot at uclibc.org
Target Milestone: ---
Attempting a build of buildroot can fail if the host machine is using an older
version of libstdc++. In this instance I was using a Docker container with
libstdc++ 3.4.13 (GLIBCXX_3.4.13).
The truncated output from the build is as follows:
>>> Sanitizing RPATH in target tree
/home/bgamble/buildroot-2019.05.1/support/scripts/fix-rpath target
Error: can't execute patchelf utility
'/home/bgamble/buildroot-2019.05.1/output/host/bin/patchelf'
make[1]: *** [target-finalize] Error 1
make: *** [_all] Error 2
Attempting to manually execute the patchelf binary will give the following
error message:
$ ./output/host/bin/patchelf
./output/host/bin/patchelf: /usr/lib/libstdc++.so.6: version
`GLIBCXX_3.4.20' not found (required by ./output/host/bin/patchelf)
This means that it is not possible to perform a build with an older version of
the libstdc++ library.
It is possible to build and execute patchelf manually using the host compiler
so I believe this is a Buildroot-specific issue and not caused by the upstream
Patchelf source.
