Re: [platform-swt-dev] Problems loading SWT on newest Linux versions

[Thomas Singer <ts-swt@xxxxxxxxxxx>]

Hi Leo,

Thank you for the answer. I thought it would be a problem of SWT 
(loading libz.so) but it was caused by a problem of SmartSVN having its 
own libz.so for the SVN libraries. The problem revealed because 
LD_LIBRARY_PATH was set to the path where the libz.so from the SVN 
binaries was provided and SWT picked that up instead the one from the 
system. I have no idea why it actually failed to load, but I now know 
how to workaround.

Sorry for the noise.
