Bonjour,

J'ai essayé de mettre à jour Gcc/G++ sous Cygwin en suivant les étapes suivantes:
1) Télécharger la dernière version de Cygwin
2) Installer Cygwin avec tous les outils nécessaires pour la compilation du nouveau GCC.

Code :

bzip2                 1.0.6-2
cygwin                1.7.9-1
gcc-core              3.4.4-999
gcc-g++               3.4.4-999
gzip                  1.4-1  
m4                    1.4.16-1
make                  3.81-2
unzip                 6.0-10
zip                   3.0-11

L'installation de Cygwin dans /opt/cygwin
3) Télécharger la dernière version de GMP, MPFR, MPC
4) unzip ces gmp-xx.zip, mpfr-xx.zip, mpc-xx.zip dán /us/local/contrib/
5) Installer GMP, MPFR, MPC en suivant les étapes pour chaque package
./configure
make
make check
make íntall

6) Unzip le contenue gcc-xx.zip dans /usr/local/contrib
7) Creer le répertoire /usr/local/contrib/build
8) Se mettre dans /usr/local/contrib/build
9) Éxécuter ../gcc-*/configure --enable-languages=c,c++
10) Éxécuter make comme suit
make 2>&1 | tee ggcmake.log

Et j'ai des erreurs suivantes dans le fichier log (extrait de la fin)

J'ai essayé de fixer ce problème mais je ne sais pas comment.

Avez-vous une idée?

Merci d'avance

Salut,
Cela risque de ne pas vraiment répondre à ton problème mais il existe un tutoriel pour compiler GCC à partir de MinGW.
Si ton objectif est de compiler GCC et peu importe de passer par Cygwin, cela peut suffire.

Merci de ton aide.
Comme cygwin vient de mettre a jour gcc je n'ai pas besoin de compiler GCC pour cygwin.

En passant j'ai compile et ca dure plus de 36 heures et ca ne repond plus. Comme je n'ai le temps de creuser (peut-etre plus tard) j'ai fait la mis a jour de gcc, gcc+ avec cygwin.


Merci
