[Ephore]

Bonjour,

J'essaie actuellement d'utiliser la librairie GSL avec QtCreator, mais je bloque sur un problème de compilation. Travaillant, sur windows, j'ai décompressé l'archive avec cygwin. Pour intégrer la bibliothèque à mon projet, j'ai modifié mon fichier .pro comme suit :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Mais lorsque je fais un

dans DataClass.h, voilà ce que me sort le compilateur :

Error while building project HRVanalysis
When executing build step 'Make'

Apparemment l'erreur viendrait du gsl_multifit.h, qui ne contient que

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

!<symlink>ÿþ.

Quelqu'un aurait-il une solution à me proposer ? ^^'

[Ephore]

En fait, je me suis rendu compte qu'il y a plusieurs fois les dossiers contenant les includes et les fichiers .a :
- dans le dossier où j'ai décompressé l'archive de la bibliothèque (C:\cygwin\home\PhuongToan\gsl-1.13)
- dans le dossier où la bibliothèque a été installée via cygwin (C:\cygwin\usr\local)

Lequel est-ce que je devrais utiliser dans mon fichier .pro ?

Lorsque j'utilise la premier,

Code :

QWT_DIR = C:\Qt\qwt-5.1.2

DEFINES += QT_DLL \
    QWT_DLL
TARGET = HRVanalysis
TEMPLATE = app
DEPENDPATH += .
INCLUDEPATH += $$QWT_DIR\src \
    $$FFTW_DIR\api \
    C:\cygwin\home\PhuongToan\gsl-1.13

    $$FFTW_DIR\.libs\libfftw3.dll.a \
    C:\cygwin\home\PhuongToan\gsl-1.13\.libs\libgsl.a \

Ca compile sans erreur lorsqu'il n'y a pas de #include <gsl/gsl_multifit.h> dans mon code. Lorsque je rajoute l'include, le compilateur sort la même erreur que précédemment.

Et lorsque j'utilise le second :

Code :

Ce n'est pas vraiment mieux: même sans #include, ça ne compile pas :

Apparemment, ce sont des problèmes de déclarations de variables, mais je n'ai pas touché aux fichiers de GSL
