Salut tout le monde, j'ai encore des nouvelles pour mon problème de compilation

J'essaie de compiler postgresql-8.4.1 sur AIX 5.3 mais j'ai un message d'erreur:

Voici la façon dont je l'ai fait:
J'ai tapé la commande configure sans options, et voici ce que j'obtiens à la fin de configure:

Après cela, j'ai lancé la compilation avec gmake et j'ai eu ce message d'erreur:

Après avoir cherché un peu et essayer de comprendre quel était le problème, j'ai remarqué qu'il doit traiter les gros fichier "large file".

Donc, j'ai essayé d'exécuter la commande configure avec l'option - disable-largefile comme suite ". / Configure - disable-largefile».

Et voici ce que j'ai eu à la fin de la commande configure avec l'option - disable-largefile:

checking for docbook2man...
checking if gcc supports -Wl,--as-needed... no
configure: using CFLAGS=-O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing -fwrapv

config.status: linking ./src/makefiles/Makefile.aix to src/Makefile.port
configure: WARNING: option ignored: --enable-largefile

Comme vous remarquez dans le warnaing, il a ignorait le "enable-largefile"

Mais quand je lance la compilation (gmake), après cela, la compilation se termine bien comme suite :

-L../../src/port -Wl,-blibpath:/usr/local/pgsql/lib:/usr/lib:/lib -Wl,-bnoentry -Wl,-H512 -Wl,-bM:SRE -o autoinc.so autoinc.o -Wl,-bE:autoinc.exp -Wl,-bI:../../src/backend/postgres.imp -L../../src/port -lpgport

gmake[1]: Leaving directory `/var/prog/postgresql-8.4.1/src'
gmake -C config all
gmake[1]: Entering directory `/var/prog/postgresql-8.4.1/config'
gmake[1]: Nothing to be done for `all'.
gmake[1]: Leaving directory `/var/prog/postgresql-8.4.1/config'
All of PostgreSQL successfully made. Ready to install.

Ma question est quel est l'effet de l'option - disable-largefile?

Je réussi la compilation avec l'option "disable-largefile", Mais je crains que je rencontre quelques problèmes dans le futur, lors de l'exécution de l'application en production.

S'il vous plaît quelqu'un peut me préciser le sens de cette option et si je désactive l'option largefile, il va avoir un effet ou non ?

Merci
