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

[Nitish Saboo]

Hi,

I compiled the syslog-ng-3.7.1.tar.gz on a Ubuntu 16.04 machine .The
syslog-ng got compiled successfully on this machine.

Libraries have been installed in:
   /home/anassa/nitish/syslog-ng-3.7.1/install/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

My project got compiled in 'syslog-ng-3.7.1' folder on machine Ubuntu 16.04.

I have a different machine  with Ubuntu 14.04.I copied 'syslog-ng-3.7.1'
folder on this machine (Ubuntu 14.04). In this machine I tried compiling my
CGO project (Go and C) where my Go code is calling the C wrapper code that
internally call syslog-ng api's.
I have defined all the CFLAGS and LDFLAGS in my Go code for the run-timne
dependencies. At the time of compilation it is failing with the following
error:

Error

lib/../deps/syslog/syslog-ng-3.7.1/install/lib/libsyslog-ng.so: file not
recognized: File truncated

Can someone please guide me what could be the possible reasons to get this
error ? What am I missing here ?


Thanks,
