Incluindo um módulo compilado no módulo envolvido com f2py (exemplo de trabalho mínimo)?
Eu tentei, mas estou falhando, obter um exemplo de trabalho mínimo. Como não preciso expor muito do meu código fortran ao python, não preciso do f2py para envolver grandes partes dele. Além disso, devido à passagem de matrizes alocáveis e à utilização de tipos derivados,Eu quero especificamente que o f2py envolva apenas o módulo de interface que criei (no exemplo a seguir 'main.f90'). Mas estou tendo problemas para obter os outros módulos que eu compilo separadamente para vincular ao meu módulo principal.
O código:Observe que todos os arquivos de origem estão em um único diretório.
Eu criei um módulo fortran que eu querocompilar (libtest.f90):
module testmod
implicit none
contains
subroutine testsub(arr)
real, allocatable, intent(in) :: arr(:,:)
print *, 'testsub executed'
end subroutine testsub
end module testmod
e um módulo fortran que eu queroenrole com f2py (main.f90):
module mainmod
use testmod
implicit none
contains
subroutine mainsub
real, allocatable :: arr(:,:)
call testsub(arr)
end subroutine main sub
end module mainmod
gfortran -c -fPIC libtest.f90
que gera 'libtest.o' e 'testmod.mod' e
f2py -c --fcompiler=gfortran -L. -I. -llibtest -m Main main.f90
O que me dá 'ld: biblioteca não encontrada para -llibtest'
Não entendo por que isso ocorre, pois parece funcionar para outras pessoas (F2PY não encontra um módulo). Se eu fizer o teste -llib, é claro que recebo (no meu script python):
Traceback (most recent call last):
File "./script.py", line 7, in <module>
import Main
ImportError: dlopen(/Users/gmueller/Workspace/Minimum_PySpin/Main.so, 2): Symbol not found: ___testmod_MOD_testsub
Referenced from: /Users/gmueller/Workspace/Minimum_PySpin/Main.so
Expected in: dynamic lookup
Edit: Note que estou no OSX (10.9.5), caso isso faça alguma diferença (mas não deveria, pois não preciso passar nenhum -shared (linux) ou -dynamiclib (osx) para o gfortran, certo? )
Aqui está a saída completa do f2py:f2py -c --fcompiler=gfortran -L. -I. -llibtest -m Main main.f90
