There are some very useful functions in systemd/src/shared that are tempting to
reuse in other, unrelated applications. My first attempt is like this:
/usr/bin/gcc -g -Wall -Wextra -std=gnu99 -I../systemd/src/systemd
-I../systemd/src/shared -I/usr/include/x86_64-linux-gnu/python2.7/
someprogram.c ../systemd/src/shared/log.c -I. ../systemd/src/shared/util.c -o
someprogram
but the result doesn't come close to compiling:
===
In file included from ../systemd/src/shared/log.c:33:0:
../systemd/src/shared/util.h:51:4: error: #error Unknown pid_t size
# error Unknown pid_t size
^
In file included from ../systemd/src/shared/util.h:87:0,
from ../systemd/src/shared/log.c:33:
../systemd/src/shared/missing.h:282:6: error: #error "neither secure_getenv nor
__secure_getenv are available"
# error "neither secure_getenv nor __secure_getenv are available"
^
===
and so on. Is it necessary to understand libtool to proceed in this
direction, or has someone already figured out how to refer to src/shared
functions in a plain old Makefile for compilation outside of the systemd source
tree?
Thanks,
Alison
