Ubuntu 18.04 problem with make

DeamonMV commented 5 years ago

Hello.

Tried to compile udp514-journal on ubuntu 18.04 and got a problems

first was this one

gcc -std=c11 -O2 -fPIC -Wall -Werror  -Wl,-z,now -Wl,-z,relro -pie -o udp514-journal udp514-journal.c
In file included from udp514-journal.c:8:0:
udp514-journal.h:23:10: fatal error: systemd/sd-journal.h: No such file or directory
 #include <systemd/sd-journal.h>
          ^~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
Makefile:25: recipe for target 'udp514-journal' failed
make: *** [udp514-journal] Error 1

I installed libsystemd-dev and then got another one:

gcc -std=c11 -O2 -fPIC -Wall -Werror  -Wl,-z,now -Wl,-z,relro -pie -o udp514-journal udp514-journal.c
/tmp/ccUwqKTG.o: In function `main':
udp514-journal.c:(.text.startup+0xa5): undefined reference to `sd_notify'
udp514-journal.c:(.text.startup+0x118): undefined reference to `sd_journal_send_with_location'
udp514-journal.c:(.text.startup+0x12a): undefined reference to `sd_notifyf'
collect2: error: ld returned 1 exit status
Makefile:25: recipe for target 'udp514-journal' failed
make: *** [udp514-journal] Error 1

Can you please describe more about compile and which applications need to install

Please install pkg-config.

The CFLAGS for libsystemd should be generated in Makefile by pkg-config, but your gcc call does not contain them. What's the output of this command?

pkg-config --cflags --libs libsystemd

DeamonMV commented 5 years ago

$ pkg-config --cflags --libs libsystemd
-lsystemd

eworm-de commented 5 years ago

That's expected and correct. So no idea what fails... The output (-lsystemd) should appear in gcc call just after -Werror.

i'll try to reboot tomorrow, and let you know if something changed.

DeamonMV commented 5 years ago

reboot. didn't helped. but main question i'm closed - i'm configured rsyslog instead of udp514-journal

eworm-de / udp514-journal
