fortran - Unresolved external symbol when linking a precompiled module -

i trying compile fortran file external precompiled module. first compile module file with:

ifort /c kdtree_mod.f90 

it generates .mod files (kdtree2_module.mod, kdtree2_precision_module.mod, kdtree2_priority_queue_module.mod).

at beginning of subroutine have:

subroutine film(h,tinf,ts,n,time) use kdtree2_module 

but when launch program gives me error:

user_film.obj : error lnk2019: unresolved external symbol kdtree2_module_mp_kdtree2_create referenced in function film user_film.obj : error lnk2019: unresolved external symbol kdtree2_module_mp_kdtree2_n_nearest referenced in function film user_film.exe : fatal error lnk1120: 2 unresolved externals link failed user_film.obj 

procedure:
1. compile module ifort /c kdtree_mod.f90
2. launch msc marc user subroutine film.
run_marc -j name_input_file -u user_subroutine
3. error

msc marc commercial software has possibility create user subroutine.

update:
tried:
1. ifort /c kdtree_mod.f90 --> generate .obj file
run_marc -j name_input_file -obj name_obj.obj -u name_input_file
compiles fine error:

forrtl: severe (170): program exception - stack overflow image

2. ifort /c kdtree_mod.f90 ifort /c user_film.f run_marc -j name_input_file -obj kdtree_mod.obj user_film.obj
read error: no such option: user_film.obj or input value: -b
   seems not able pass both .obj files.

3. ifort /c kdtree_mod.f90 ifort /c user_film.f kdtree_mod.obj ifort: warning #10146: no action performed specified object file(s)

update 2 able compile dll file these commands:

ifort /nologo /iface:stdcall /libs:dll /threads /c kdtree_mod.f90 link /nologo /subsystem:windows /manifest /dll /out:kdtree_mod.dll kdtree_mod.obj mt /nologo “/outputresource:kdtree_mod.dll;#2″ /manifest kdtree_mod.dll.manifest 

the useful information found on internet in german cad forum, says, there run_marc following:

fcomp=ifort ... fortran="$fcomp -c -assume byterecl -safe_cray_ptr $profile -save -zero -mp -wb -w90 -o1 $i8fflags -i$marc_source/common \ -i$marc_source/bcssolver/common -i$marc_source/mumpssolver/include $i8defines -dlinux -dlinux -dlinux_intel $fdefines $ddm $solverflags" 

you need add -obj kdtree_mod.obj or command line. descriptions there sounds possible link against libraries, might option create library , use via path more in line general usage of tool.

regarding first update: wouldn't have expected -obj option work @ all. meant, need modify run_marc script itself. according link above appears script variable containing run script in it. might case on unix systems, , on windows solved differently. did try run_marc script? have no clue, first command in update, compiles, name_obj of sudden?

in second command, have expected like:

run_marc -j name_input_file -u user_film -obj kdtree_mod.obj 

though, outlined above, don't think obj gets passed on.

regarding second update, , comment below:

besides linking need have module file available in include path. include path of compiler includes current working directory, if can put module file directory compiler executed, ought work. or put in 1 of directories stated via -i options in compiling fortran command above. or, modify command , add own include path it.

how command pastebin set userdll option filled:

ifort  /fpp /c /dwin32_intel  -d_implicitnone /nologo       -dmkl -dopenmp -domp_compat -d_mscmarc -dwin64       /i"c:\msc.software\marc\2014.0.0\marc2014\common"       /i"c:\msc.software\marc\2014.0.0\marc2014\bcsgpusolver\common"        /i"c:\msc.software\marc\2014.0.0\marc2014\mumpssolver\include"        /i"c:\msc.software\marc\2014.0.0\marc2014\intelmpi\win64\include"       /o2 /qip /qvec- /qsafe-cray-ptr /switch:fe_old_modvar       /w0  /qopenmp /qopenmp-threadprivate:compat  -dcasi -dpardiso -dmumps       -dbcsgpu -dcuda /md -dddm       /object:"c:\users\yellowhat\desktop\prova\user_film.obj"       "c:\users\yellowhat\desktop\prova\user_film.f" 

it looks c:\msc.software\marc\2014.0.0\marc2014\common location put kdtree *.mod files into.
