自动工具生成Makefile时，多个程序共享一个源文件

Question

This question concerns mostly Unix/Linux style C development. I am using autotools to generate Makefile .

There are two programs share a source file named utils.c .

The structure of my source tree goes like this:

app/
    src/
        server/
            server.c
            ...
        client/
            client.c
            ...
    include/

The question is where should I put the shared source file and how should I write my Makefile.am or configure.ac to make it work.

The current configure.ac only specify the AC_CONFIG_FILES([Makefile src/Makefile])

And the current src/Makefile.am goes like this:

bin_PROGRAMS = server client
server_SOURCES = server/server.c
client_SOURCES = client/client.c
server_LDADD = $(DONT_KNOW_WHAT_TO_WRITE)
client_LDADD = $(DONT_KNOW_WHAT_TO_WRITE)

Thanks.

If it is just one relatively small source file, you might as well add it to the respective _SOURCES lines.

If the shared code consists of multiple files, you could create a static library. https://www.gnu.org/software/automake/manual/html_node/A-Library.html
