Makefile link math.h - makefile

I try to add LDLIBS=-lm to my makefile, to link math.h, but I get the same error as before "sin undeclared " function. Here is part of my makefile:
I appreciate your help in advance.
LDLIBS=-lm

Why is automake prefixing my object files with the package name?

In my src directory, I have source files such as cells.c. When I perform a compilation, the compiler prefixes the object file with the package name, so that it becomes neoleo-cells.o, for example. Why is it doing this, and how can I stop it? I don't think it's standard behaviour.
Here is Makefile.am:
#VPATH = $(srcdir) $(builddir)
GUI_SRCS =
GUI_LINK =
#GUI_DEFINES = -DX_DISPLAY_MISSING
GUI_DEFINES = -DHAVE_X
# Order of linking of libraries for Motif seems to be important
# I have decided to mandate the use of the Xbae library, rather than
# have it optional.

# plotter.c xbase.cpp
ref.o : parse.h
#neoleo_wrap.c : $(srcdir)/neoleo.i neoleo_swig.c neoleo_swig.h
# swig -tcl8 -o $# $<
This line causes the rename of the object files:
neoleo_CFLAGS = $(GUI_DEFINES) -Dmain0=main
If you have target-dependent compilation flags, Automake chooses different names for the resulting object files. This approach avoids clashes if there are multiple different targets that use the same sources but different flags.
Now, Automake could in theory notice that this isn't happening and not rename the object files. However, in practice most people don't care what the intermediate files are called, and this approach, I believe, simplified the implementation.
In your case, it sounds like you do care. So, just rename that variable to AM_CFLAGS and everything should work as you expect.

How do I compile VASP 5.4.1 on a Cray XC

I want to compile the latest version of VASP 5 (5.4.1) on a Cray XC MPP machine. Does anyone have the settings I can use? The VASP distribution does not come with an example for Cray.
The build system has changed from the 5.3.5 version.
Full compilation instructions can be found on the ARCHER (http://www.archer.ac.uk) website at:
http://www.archer.ac.uk/documentation/software/vasp/compiling_5-4-1-phase2.php
But in brief:
Download and patch the source code
Switch to Intel programming environment and load the fftw module:
module swap PrgEnv-cray PrgEnv-intel
module load fftw
Create "makefile.include" with the following settings:
# Precompiler options

How to link against just built libraries in autotools project

How can I link an executable in say test subdirectory of an autotools project against a library, say libfoo, that is just built from files in src directory of same project?
Makefile.am looks like:
SUBDIRS = src . test
AUTOMAKE_OPTIONS = subdir-objects
ACLOCAL_AMFLAGS = ${ACLOCAL_FLAGS} -I m4
src/Makefile.am:
ACLCAL_AMFLAGS = ${ACLOCAL_FLAGS} -I m4
lib_LTLIBRARIES = libfoo.la
libfoo_la_SOURCES = \
foo.cpp
foo_includedir = $(includedir)/foo
foo_include_HEADERS = \
foo.hpp
test/Makefile.am:
ACLCAL_AMFLAGS = ${ACLOCAL_FLAGS} -I m4
check_PROGRAMS = footest
footest_SOURCES = \
main.cpp
footest_LDADD = ?????
That's easy: footest_LDADD = ../src/libfoo.la
This works for 'out-of-tree' builds, e.g., if you invoke configure from another directory (not ./configure).

PROBLEM: empty Makefile.am caused infinite loop
SOLUTION: add an empty variable to it

how to set conditional bin program creation using autotools

I am a beginner in using autotool, I want to add some shell script in the Makefile.am, when I use the method below, the Makefile created by autotool is not I am expected. How can I write to create the correct one.
Thanks for your reply!
PS:
this is my configure.in and Makefile.am(parts)
configure.in:
if test "$sample" = yes;then
DEFS="$DEFS -DSAMPLE=1"
AC_SUBST(SAMPLE, [yes])
fi
Makefile.am:
if test "$SAMPLE" = yes;then
noinst_PROGRAMS = test
test_SOURCES = test.c
else
bin_PROGRAMS = release
release_SOURCES = main.c
fi
Makefile autotool created:
........
........
.PHONY: CTAGS GTAGS all all-am check check-am clean clean-generic \

if test "yes" = yes;then
fi
Automake conditionals don't work like that. See the manual.
Here's how it should look:
configure.ac:
AM_CONDITIONAL([SAMPLE], [test "$SAMPLE" = yes])
Makefile.am:
if SAMPLE
noinst_PROGRAMS = test
test_SOURCES = test.c
else
bin_PROGRAMS = release
release_SOURCES = main.c
endif
