Einschließen eines kompilierten Moduls in ein Modul, das mit f2py umschlossen ist (Minimales Arbeitsbeispiel)?
Ich habe versucht, aber ich versage, ein minimales Arbeitsbeispiel zu bekommen. Da ich nicht viel von meinem fortran-Code für Python verfügbar machen muss, brauche ich f2py nicht, um große Teile davon zu verpacken. Aufgrund der Übergabe zuweisbarer Arrays und der Verwendung abgeleiteter Typen ist Ich möchte ausdrücklich, dass f2py nur das von mir erstellte Schnittstellenmodul umschließt. (im folgenden Beispiel 'main.f90'). Ich habe aber Probleme, die anderen Module, die ich separat kompiliere, zu meinem Hauptmodul zu verlinken.
Der CodeHinweis: Alle Quelldateien befinden sich in einem einzigen Verzeichnis.
Ich habe ein fortran Modul erstellt, das ich erstellen möchtekompiliere (libtest.f90):
module testmod
implicit none
contains
subroutine testsub(arr)
real, allocatable, intent(in) :: arr(:,:)
print *, 'testsub executed'
end subroutine testsub
end module testmod
und ein fortran Modul, das ich möchtewrap with 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
, das 'libtest.o' und 'testmod.mod' erzeugt, und
f2py -c --fcompiler=gfortran -L. -I. -llibtest -m Main main.f90
Was gibt mir 'ld: Bibliothek für -llibtest @ nicht gefund '.
Ich verstehe nicht, warum dies auftritt, da es für andere zu funktionieren scheint F2PY findet kein Modul). Wenn ich den -llibtest rausnehme, bekomme ich natürlich (in meinem Python-Skript):
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: Hinweis: Ich arbeite unter OSX (10.9.5), falls dies einen Unterschied macht (sollte es aber nicht, da ich kein -shared (linux) oder -dynamiclib (osx) an gfortran übergeben muss, richtig ?).
Hier die volle Ausgabe von f2py:f2py -c --fcompiler=gfortran -L. -I. -llibtest -m Main main.f90
