Comment puis-je comprendre ces erreurs terribles lors de la construction de gcc-4.8.2?

J’essaie d’installer le compilateur gcc-4.8.2 sur un système Debian 7 distant, auquel je n’ai pas de privilèges root , mais uniquement un access ssh . J’ai compris que le moyen le plus simple serait de comstackr le compilateur à partir des sources.

Je suis ce manuel d’installation court de la page Web de GCC.

Fondamentalement, j’ai fait l’ installation la plus simple , qui est résumée au bas de la page:

tar xzf gcc-4.8.2.tar.gz cd gcc-4.8.2 ./consortingb/download_prerequirejsites cd .. mkdir objdir cd objdir $PWD/../gcc-4.8.2/configure --prefix=$HOME/gcc-4.8.2 --enable-languages=c++ make

avec la petite exception que je n’ai pas exécuté le script ./consortingb/download_prerequirejsites sur la machine distante en raison de ressortingctions de pare-feu. Au lieu de cela, je l’ai exécuté sur ma machine locale, puis j’ai compressé le dossier entier dans gcc-4.8.2.tar.gz et l’ gcc-4.8.2.tar.gz sur la machine distante. Là, j’ai recréé les liens symboliques vers les bibliothèques prérequirejses (gmp, …) et lancé make . Après quelques secondes, je reçois des erreurs incroyables:

Je comstack avec gcc 4.7.2-5 sur Debian .

Sur la machine locale, il y a Ubuntu 13.10 avec gcc 4.7.3 et la construction semble bien aller (toujours en cours).

S’il vous plaît, quelle pourrait être la cause de ces erreurs?

MODIFIER:

J’ai vérifié le fichier /home/mdrozdik/gccbuild/libcpp/config.log . C’est très long mais à deux endroits il y a ces erreurs:

 configure:3086: gcc -V >&5 gcc: error: unrecognized command line option '-V' gcc: fatal error: no input files compilation terminated. configure:3097: $? = 4 configure:3086: gcc -qversion >&5 gcc: error: unrecognized command line option '-qversion' gcc: fatal error: no input files compilation terminated. configure:3097: $? = 4

Mais le journal continue cependant pour plusieurs pages.

J’ai eu un problème similaire (gcc 4.8.3) et ceci l’a résolu: g ++ 4.7.1 erreur de compilation: types contradictoires pour ‘strsignal’

La solution consistait à supprimer un certain nombre de drapeaux du compilateur C (CPATH, etc.)

https://stackoverflow.com/users/1224886/tsbertalan a rapporté que cela a fonctionné pour lui (et c’est ce que j’ai utilisé):

 unset LIBRARY_PATH CPATH C_INCLUDE_PATH PKG_CONFIG_PATH CPLUS_INCLUDE_PATH INCLUDE
