Newbie Automake Problem

[JASON TILLEY]

I am trying to create a Makefile.am for a package on github in order to make it more friendly to packaging (https://github.com/sakov/csa-c). I am having linking problems on my Mac. I’m sure its my complete lack of understanding of Automake. My make command executes the following:

Where is the Makefile.am? We need to see that to be able to diagnose your issue.

At least the '-lm -lcsa' argument on the linking command looks fishy.

[JASON TILLEY]

I have been editing my Makefile since the original post, so the linker is no longer getting ‘-lm -lcsa’. The final lines now look like this:

/bin/sh ./libtool --tag=CC --mode=link /opt/local/bin/gcc -O2 -m64 -fPIC -g -Wall -L/opt/local/lib -o csabathy src/csabathy-csa.o src/csabathy-svd.o src/csabathy-minell.o libcsa.la -lm -L/opt/local/lib
libtool: link: /opt/local/bin/gcc -O2 -m64 -fPIC -g -Wall -o .libs/csabathy src/csabathy-csa.o src/csabathy-svd.o src/csabathy-minell.o -L/opt/local/lib ./.libs/libcsa.dylib -lm
Undefined symbols for architecture x86_64:
"_main", referenced from:
implicit entry/start for main executable
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
make: *** [csabathy] Error 1

My Makefile.am contains this currently:

ACLOCAL_AMFLAGS = -I m4 --install

lib_LTLIBRARIES = libcsa.la
libcsa_la_SOURCES = src/csa.c \
src/svd.c \
src/minell.c
libcsa_la_LIBADD = -lm

include_HEADERS = src/csa.h src/svd.h src/minell.h src/nan.h

bin_PROGRAMS = csabathy
csabathy_SOURCES = src/csa.c \
src/csa.h \
src/svd.c \
src/svd.h \
src/minell.c \
src/minell.h \
src/nan.h
csabathy_CFLAGS = $(AM_CFLAGS)
csabathy_LDADD = libcsa.la -lm
csabathy_DEPENDENCIES = src/csa.lo \
src/svd.lo \
src/minell.lo

EXTRA_DIST = /src/m4/NOTES

Thanks for the help.

You should not need this done this directly. Use |AC_CHECK_LIB()| or
similar macro in |configure.ac| to detect if you need it.

include_HEADERS = src/csa.h src/svd.h src/minell.h src/nan.h
bin_PROGRAMS = csabathy
csabathy_SOURCES = src/csa.c \
src/csa.h \
src/svd.c \
src/svd.h \
src/minell.c \
src/minell.h \
src/nan.h

You are using the same sources as the |libcsa.la| library but you are
actually linking to the library for the executable. This does not make
much sense.

Also, remove the |.h| files from the list.

Post by JASON TILLEY
csabathy_CFLAGS = $(AM_CFLAGS)
csabathy_LDADD = libcsa.la -lm

|-lm| again.

Post by JASON TILLEY
csabathy_DEPENDENCIES = src/csa.lo \
src/svd.lo \
src/minell.lo

Why do you need this? I do not think it is necessary. The appropriate
objects are linked in through the |libcsa.la| library.

This should probably not be an absolute path.

implicit entry/start for main executable
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
make: *** [csabathy] Error 1
Does anyone know what this error means? Thanks.

Where is the Makefile.am? We need to see that to be able to diagnose your issue.
At least the '-lm -lcsa' argument on the linking command looks fishy.
