 |
|
Bonjour a tous,
Alors voila j'ai sacré problème avec gcc, il me sort des programmes qui ne marchent pas 
exemple:
| Code: |
// hello.c
#include <iostream>
int main (int argc, char *argv[]){
std::cout << "HelloWorld\n";
return 0;
}
|
# g++ -Wall -o hello hello.c
là OK ça roule... mais ensuite
#./hello
bash: ./hello: Permission denied
peu importe qui essaye de lancer hello. (même root)
pourtant emerge marche bien. je comprend vraiment pas. je suis pas un grand expert en programmation mais je sais que ça devrais marcher ça pourtant.
même des programmes que j'avais fait avant (sur une autre install) et qui marchais merdouille comme ça.
mon emerge --info:

Une idée comme ça : ton programme qui ne s'exécute pas, il est où ? Dans ton home ? dans /tmp ?
Et quelles sont les options de montage de la partition en question ? je parie que y a un noexec qui traîne

le programme en question n'est ni dans mon home ni dans /tmp...
voici mon fstab:
| Code: |
# <fs> <mountpoint> <type> <opts> <dump/pass>
/dev/disk/by-id/scsi-SATA_WDC_WD1600JD-00WD-WMAES3261030-part1 / ext3 noatime 0 0
/dev/disk/by-id/scsi-SATA_WDC_WD1600JD-00WD-WMAES3261030-part3 none swap sw 0 0
/dev/cdrom /mnt/cdrom auto noauto,ro,users 0 0
# PTI DIMENSION !
/dev/disk/by-id/scsi-SATA_WDC_WD1600JD-00WD-WMAES3261030-part2 /mnt/pti ext3 auto,rw,users 0 0
# GRO TORTURE ROOM !
/dev/disk/by-id/scsi-SATA_SAMSUNG_HD501LJS0MUJ1MP747756-part1 /mnt/gro ext3 auto,rw,users 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
|
la partoche en question c'est pti
donc pas de noexec qui traine. |

Guilc a raison, ton problème vient de noexec...en effet ta partoche est montée avec l'option users et celle ci implique noexec.... cf man mount :
| Code: |
users Allow every user to mount and unmount the file system. This option implies
the options noexec, nosuid, and nodev (unless overridden by subsequent
options, as in the option line users,exec,dev,suid).
|
donc rajoutes exec....
