CPPFLAGS and AC_CHECK_HEADERS

[Jose Roman Bilbao]

Hi again,

Do you know why this is not working?, is there something wrong I am
missing?: (The problem is specified at the end)

AC_INIT
AM_CONFIG_HEADER(config.h)
AM_INIT_AUTOMAKE(Xmipp,0.9)
AC_PROG_LIBTOOL
AC_PROG_CPP
AC_SUBST(XMIPP_PREFIX)

# checking for the existence of VTK on regular PATH
AC_MSG_CHECKING("VTK library dir")
AC_ARG_WITH(vtk-libdir,[  --with-vtk-libdir=DIR           location of
the vtk lib directory],
        [LDFLAGS="${LDFLAGS} -L${withval} -lvtkCommon -lvtkImaging -lvtkIO
-lvtkGraphics" ])

AC_ARG_WITH(vtk-incdir,[  --with-vtk-incdir=DIR           location of
the vtk include directory],
        [CPPFLAGS="${CPPFLAGS} -I${withval}"])

# If vtk is not found and no valid --with-vtk-libdir PATH
# has been provide configuration finishes

AC_CHECK_LIB(vtkCommon, main,,
        [AC_MSG_ERROR([VTK not found; Check your installation or try
./configure --with-vtk-libdir=/libdir/for/vtk])])
AC_CHECK_LIB(vtkImaging, main,,
        [AC_MSG_ERROR([VTK not found; Check your installation or try
./configure --with-vtk-libdir=/libdir/for/vtk])])
AC_CHECK_LIB(vtkGraphics, main,,
        [AC_MSG_ERROR([VTK not found; Check your installation or try
./configure --with-vtk-libdir=/libdir/for/vtk])])
AC_MSG_RESULT($CPPFLAGS)
AC_CHECK_HEADER([vtkImageFFT.h],,
        [AC_MSG_ERROR([VTK headers not found; Check your installation or try
./configure --with-vtk-incdir=/libdir/for/vtkheaders])])

The problem is on the last stage. The header vtkImageFFT is where I have
pointed with --with-vtk-incdir but the test does not detect it. Do you
know why is it?.

I am sorry for the inconveniences I can create to you but I am rather
new on this of autoconf.

Many thanks
