here is my source tree

and here are the Makefile.am and configure.ac
FILE: configure.ac
Code:
AC_INIT([triangle], [1.0], [selva.developer@gmail.com])
AC_CONFIG_AUX_DIR([build/build-aux])
AM_INIT_AUTOMAKE([foreign -Wall -Werror])
AC_PROG_CC
AC_PROG_INSTALL
AC_PROG_RANLIB
AC_CONFIG_HEADERS([config.h])
AC_CONFIG_FILES( [Makefile
lib/Makefile
helloworld/Makefile]
)
AC_OUTPUT
FILE: Makefile.am
Code:
SUBDIRS = helloworld lib
FILE: helloworld/Makefile.am
Code:
AM_CFLAGS = -I$(srcdir)/lib
LDADD = ../lib/libshaderutils.a
bin_PROGRAMS = triangle
triangle_SOURCES = triangle.c
FILE: lib/Makefile.am
Code:
lib_LIBRARIES = libshaderutils.a
libshaderutils_a_SOURCES = shaderutils.c shaderutils.h
include_HEADERS = shaderutils.h
and when I run the autotools the following error is thrown
Code:
