[jira] Updated: (HARMONY-3091) CLONE -Linux-- C++ library compatibility

["Chris Elford (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HARMONY-3091?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chris Elford updated HARMONY-3091:
----------------------------------

    Environment: RedHat Enterprise Linux 4 Update 4 -- x86_64  (was: Fedora Core 6 -- x86)

Note that this problem (cloned) is not limited to new OSes like Fedora Core 6.  I have verified the same issue exists for RedHat Enterprise Linux 4 Update 4 in the x86_64 version.

To get the binary versions to run on this platform, one needs to install the "Legacy Software Development" packages.

> I tried to use the binary JRE bundle from the web site (jre-r468731) to run a hello world application.
> I got error: java/lang/UnsatisfiedLinkError : Failed loading library "libhytext.so": DSO load failed
> According to strace, the issue appears to be an inability to load the nonexistant libstdc++.so.5.  By installing the gcc 3.3.4 compatibility libraries (compat-libstdc++-33 package), I was able to get it to work.
> It would be good to document the needed library set or have a more meaningful error message than failure to load libhytext.so.
> Another anomoly that appeared when running strace is that it appears to load BOTH libstdc++.so.6 AND libstdc++.so.5.  This seems to be quite odd and seems to indicate that some components were compiled with one compiler and some other components were compiled with another compiler.  It looks like libharmonyvm.so uses a current compiler while the hytext library uses an older compiler.
> strace logs from the failure and after  the legacy compatibility libraries were installed are attached.
