[syslog-ng] Getting error : .../libsyslog-ng.so: file not recognized: File truncated

[Peter Kokai (pkokai)]

Hello,

Have you verified if both file is the same (no transport issue) ? (check sha256sum)
Could other tools - that understands elf - read that library ? (readelf -a syslog..so)

What was the exact linker option it was called with ? (you can ask gcc/clang to emit such information with -### option)
