linke ifort with created lib

[ppthelion]

Hi:
I have problem with run with created lib "HEALPix" which down from JPL .my environment is "Fedora 12 , ifort 11.064" ,what I have done as follows:
the command I used: compile:ifort -c check_HEALpix.f90 -I{INCLUDE} -I/opt/healpix/include -L{LIBRARY_PATH} -L/opt/healpix
/lib/libhealpix.a -fpp -assume underscore
it sounds no errors or warnnings.but then I want to run it
run : ifort -o check check_HEALpix.o
the compilor showed: check_HEALpix.o: In function `MAIN__':
check_HEALpix.f90:(.text+0x236): undefined reference to `pix_tools_mp_nside2npix_'
check_HEALpix.f90:(.text+0x6d5): undefined reference to `pix_tools_mp_pix2vec_ring_'
check_HEALpix.f90:(.text+0x733): undefined reference to `pix_tools_mp_vec2ang_'
check_HEALpix.f90:(.text+0x804): undefined reference to `alm_tools_mp_alm2map_sc_d_'
check_HEALpix.f90:(.text+0x822): undefined reference to `alm_tools_mp_map2alm_sc_d_'
check_HEALpix.f90:(.text+0x940): undefined reference to `alm_tools_mp_alm2map_sc_d_'
But when I checked the library
:: nm /opt/healpix/lib/libhealpix.a | egrep "pix_tools_mp_vec2ang"
the result is ::00019760 T pix_tools_mp_vec2ang_
it seems that this function is contained in the library,so why this happens?
Any hints is appreciated
Thanks

Did you check whether the library is for the same architecture as your compiler?
file healpix.a
ifort -V

Thanks for your reply,I did as your follows,but I don't know if there any difference between them.
file healpix.a :: (result) current ar archive
ifort -V :: (result) Intel Fortran Compiler Professional for applications running on IA-32, Version 11.1 Build 20090827
