Hi! This is a question to all autoconf/automake experts out here.
I have a package which has kernelmode modules and usermode programs.
Now both of them use a common library file which can be compiled into either
kernel mode or userland mode, depending on which it is being linked against.
How do I define using automake definitions to get this file compiled twice -
once in kernel mode and once in userland mode?
e.g. my package tree looks like this:
$(top_srcdir)
|
+------- common/ : commonlib.c
|
+------- kernel/ : kernelmod.c
|
+------- user/ : userprog.c
Now the kernel module needs to be linked with commonlib.o AFTER commonlib.c
has been compiled using Kernel module directives. (-D__KERNEL -DMODULE -O2 etc.)
userprog application needs to be linked with commonlib.o AFTER commonlib.c
has been compiled using normal directives.
How do I get commonlib.c to be compiled twice using different options.
If I use the following definitions, it is flagged as an error because the object file
is not created in the current directory.
user/Makefile.am:
bin_PROGRAMS = userprog
userprog_SOURCES = ../common/commonlib.c
