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 :

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 ? ^^'
