Does anyone know of a CentOS 6 compiled version of the widevine DRM

With Firefox 60ESR, Netflix (e.g.)  installs a version in your
~/.mozilla/firefox/(profile name)gmp-widevinecdm/ directory but it has
the
following library failures in 'ldd' output:

ldd libwidevinecdm.so
./libwidevinecdm.so: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.5'
not
found (required by ./libwidevinecdm.so)
./libwidevinecdm.so: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14'
not found (required by ./libwidevinecdm.so)
./libwidevinecdm.so: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15'
not found (required by ./libwidevinecdm.so)



I have not tried playing DRM things on the CentOS-6 browser .. but this
looks like a place to start:

https://support.mozilla.org/en-US/kb/enable-drm

To be clear .. I don't know if the compiled version of firefox we
shipped has a DRM widevine that will work with netflix .. the error you
are getting seems to happen because of where:

libwidevinecdm.so

was compiled (against which glibc-devel).

so .. maybe adding in the google widevine and somehow disabling the
built in firefox one might work .. OR .. disabling the google version
might work, etc.


It appears firefox downloads the google library each time it is requested,
and the one it downloads is compiled against the wrong libraries.

I realize this is not a CentOS support issue per se, I was inquiring if
anyone in the community, or upstream,  had dealt with this before.

I agree, we should apply directly to one of these three letter agencies to have their code straightened up ;-) I don't know which one though.

I understand the CentOS 7 version works fine, however we are still running
CentOS 6.
