[SOLVED] help with automake

RudraB · 10-02-2012, 08:57 AM

Code:

exe=ptbl 
CC=gcc 
CFLAGS =-O3 
SUBDIR=files 
PCONF1=pkg-config --cflags --libs gtk+-2.0 
sources := $(wildcard $(SUBDIR)/*.c) 
objects := $(sources:.c=.o) 
$(exe): $(objects) help.c  table.c  callbk_list.h  cwlst.h
         $(CC) `$(PCONF1)` $(objects) help.c  table.c -o $(exe)  
$(SUBDIR)/%.o: $(SUBDIR)/%.c
         $(CC) -c `$(PCONF1)` $<
         mv $(*F).o $(SUBDIR)/$(*D)  
clean:         rm -vf $(SUBDIR)/*.o $(exe)

I would like to achieve the same goal using autotools.
I googled, but all seems to assume there is a executable in each directory, like each, for me, files/Makefile.am *MUST* have a bin_PROGRAM, which is *NOT* what I am looking for. Can you kindly help me?

How can you expect one to read that unreadable mess, while even TABs matter in Makefiles?
Please edit your first post using [code][/code] tags around source code/commands output to make it readable.

Edited, and viewable now.
Please have a look.

Thanks, that's so much better.

I'm not too fluent with autotools (having written only one project with them), but I didn't have to specify a bin_PROGRAM when compiling some source files to be later linked into the executable. What I had to do, however, was to specify a lib_LIBRARIES variable containing the name of the static library I was gonna use thereon.
This is my Makefile.am for that small library (just a parser for a 3D mesh specification text file):

Code:

GRAMMAR_PREFIX=mfile_
SUBDIRS=m_files
noinst_PROGRAMS=parseTest
lib_LIBRARIES=libmfile.a

## Had to add the autogenerated lexer and parser to LDADD... O_o

AM_YFLAGS=-d -p $(GRAMMAR_PREFIX)
AM_CFLAGS=-Im_files/ -I..
libmfile_a_SOURCES=m_files/m_lexer.l m_files/m_parser.y m_parsing_util.c m_print_visitor.c m_stats_visitor.c m_toMeshDescriptor.c ../meshUtil.c libmfile_wrapper.c
parseTest_LDADD=libmfile.a
parseTest_SOURCES=test_m_parsing.c

You can safely ignore those AM_YFLAGS (automake flags for yacc) and things regarding parseTest, as it just was a test program to see if the parsing went smooth with some example files.
To use the code compiled as a static library, you'll add to modify your top level binary LDADD flags, eg:

Code:

bin_PROGRAMS=foo

foo_LDADD=dir/libbar.a

Hope this is helpful.

Thanks,
I will try.
