[syslog-ng] syslog-ng 3.7.x support on armv7 architecture

Thu Feb 18 15:05:06 CET 2016

Thanks Czanik  for detailed information.
I have included following libraries . Please let me know if this is ok.  I have not included libjson.

·         EVTLOG

·         GLIB

·         PCRE

·         OPENSSL

Since my requirement is  sending syslog  log messages over TLS and it is on embedded systems I have to include minimum number of libraries.
Please let me know if any of the libraries can be removed

Regards,
Girish

Hi,

I never did cross compiling, so I can't help you in that one, but compiling nativity on a Raspberry Pi 2 using an up-to-date Raspbian as OS worked fine. First I installed all development dependencies, downloaded an unpacked sources. Next I ran configure with python support disabled (did not have time to debug why configure failed to find python, but most likely you don't need it anyway in an embedded environment). Next I built it and ran make check to see if self check succeeds. Everything was all right. Make install put the whole thing under /usr/local. As it's the only software there, it's easy to remove it using 'find /usr/local -type f -delete' :)

apt-get install gcc make flex bison libssl-dev libglib2.0-dev autoconf libtool libevtlog-dev libjson0-dev

cd syslog-ng-3.7.2

./configure --disable-python

make

make check

Thanks Peter.
I started using syslog-ng 3.7.2.

Armv7 hardware is BCM56340(Helix4) from broadcom
My requirement is sending syslog messages over TLS to remote server.
My compilation went fine for power pc architecture.
But  for ARMv7 I am having problem as I  mentioned earlier.

Following is the error. As other community friends suggested to I tried setting magic CFLAGS and LDFLAGS. But could not succeed.
Could you please share your experience.

Hi,

Starting with syslog-ng 3.7, sources are only published on github.
This is the current stable version, 3.8 is the current development version, which is now git head.

BTW: could you write about your use case? On which ARMv7 hardware do you use syslog-ng? How do you (plan to) use it? (I'm an ARM addict, running syslog-ng on the Raspberry Pi2)
