This work is under progress

These are working notes for the Phelib connection to Capsis, made in June 2015 (Isabelle chuine, Yassine Motié, Inaki Garcia, Gallian Colombeau, Hendrik Davi, Hélène Raynal, Eric Casellas, F. de Coligny)

• JNA: Getting started
• Java - Fortran connection with JNA for Organon in Capsis, September 2014

• Trouble while searching the dll: https://www.chilkatsoft.com/java-loadLibrary-Linux.asp
• How to tell if .dll is 32 bits or 64 bits?

Preparation notes:

• Phelib source files in /home/coligny/des-trucs/phelib
• Downloaded jdk 7 windows 32 and 64 bits
• Compile the dll for windows 64 bits
• copy the dll to capsis4/ext/windows64/

• make sure the dll path is in java.library.path AND in the system PATH variable
• Add in capsis.bat : PATH=%jlp%;$PATH

fonctions interface possibles :

String getVersion ()

init (String path_xml_file)
    appelle execute () de phelib

int getPhaseCount ()
    retoure le nombre de phases gérées par le métamodèle
    utilisable pour tailler les tableaux float[] de la fonction f(), en fin de signature

f (site, year, doy, latitude, 

    float[] climat_t, 
	Dans l'ordre attendu par Phelib (recompilation si changelent de modèle Phelib)
	Exemple : 
	tmoy, 
	tmin, 
	tmax, 
	pre, 
	wind
    float[] climat_t+1, 
	Idem, même ordre (incluant tmin_t+1, Option 2)

    int[] prevId, float[] prevValue,  -> valeurs retournées la veille
    int[] newId, float[] newValue); -> resultats : phases et valeurs

Quelques erreurs rouges dans Dependency Walker

2 fics: dll et dlla

Localisation du projet, sources Phelib: C:/tmp

dans standalone/src/CmakeList SHARED → dll (sinon STATIC)

c:/boost_include c:/mingw

compilation c:/Users/051E999/local/lib → libPhelib.dll

La méthode getVersion n'est pas trouvée par Java Phelib.java

fc - 1.7.2015

Des exemples de functions interfaces à la fonction compute en place dans Phelib (modification différée pou qu'elle renvoie plusieurs phases en cours).
