Hello all,
I am building OpenOffice trunk in a CentOSX Environment running as a docker
image. Anyone has an Idea where to look. The versions look very old and even
for CentOSx not up to time.
My host system is Arch Linux. I run into a strange QA Issue:
Entering workspace/AOO/github/main/sal/qa/osl/condition
../../../unxlngx6.pro/bin/sal_ut_osl_condition: /lib64/libstdc++.so.6:
version `GLIBCXX_3.4.20' not found (required by
workspace/AOO/github/main/solver/450/unxlngx6.pro/lib/libgtest.so.0)
I don't know Docker, but what you wrote below may give us a
suggestion.
[...]
My Config:
[ ...snip as nothing seems wrong there ... ]
My Docker build environment:
FROM centos:7
RUN yum update -y
RUN echo "assumeyes=1" >> /etc/yum.conf
RUN yum install epel-release -y
RUN yum install -y\
gcc \
expat-devel \
openssl-devel \
autoconf \
gcc-c++ \
Here we are.
It is part of the guide. see [1]
Does this needs to change?
(The guide differs a bit with the docker commands, since it did not work
out of the box.
If I understand correctly, you are installing an older C++ (from
Centos 7) into your up-to-date system.
The error message is about a library mismatch between
/lib64/libstdc++.so.6 and one of the shared libraries you compiled.
Is it possible that, for some reason, the AOO build system is not
always using the same version of GCC, or the same libraries? I.e. it
is mixing them from the CentOS installation and from the host system?
Or maybe the Docker image contains multiple versions of GCC, and the
build system is mixing them?
This could lead to errors similar to the one you reported.
You can get information about individual libstdc+ versions with the
following command:
$ strings /path/libstdc++.so.6 | grep GLIBCXX
And from here:
https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html you can see
that GLIBC_3.4.20 corresponds to GCC 4.9.0.
I hope this helps.
However I believe that during my tries to make the docker image world I
tried to build OpenOffice with different gcc version as you have suspected.
Thanks for pointing this out.
