no longer able to compile

Ljubomir · 03-15-2005, 01:42 PM

Hi all,

For unknown reasons I am no longer able to compile programs. When I run

Code:

./configure

script from _ANY_ project i get only:

Code:

bash: ./configure: /bin/sh: bad interpreter: Permission denied

So I run it through:

Code:

sh ./configure

but it ends at:

Code:

checking whether the C compiler works... configure: error: cannot run C compiled programs.

I've checked config.log, and found:

Code:

configure:2823: checking whether the C compiler works
configure:2829: ./a.out
./configure: line 2830: ./a.out: Permission denied
configure:2832: $? = 126
configure:2841: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.

Same is when running as root. Any ideas?

suse 9.2 prof
gcc version 3.3.4 (pre 3.3.5 20040809)

I've compiled many apps on this machine just few weeks ago...

try entering this into foo.c

Code:

int main () { }

then run:

Code:

$ gcc foo.c -o foo
$ ./foo
$ echo $?

if an error happens, post the output; also, do post the output of echo $?

Code:

ljubomir@Fidel:~> gcc foo.c -o foo
ljubomir@Fidel:~> ./foo
ljubomir@Fidel:~> echo $?
16
ljubomir@Fidel:~>

No output, just echo returns code 16.

that's weird. Post
$ gcc --version

Do you think updating gcc might help?

jonaskoelker · 03-29-2005, 02:58 AM

it might. Also worth updating: the C library (`glibc[something]', iirc). I expected `echo $?' to return `0'; why it doesn't fails me, but I think it might be the C library. Post the output of `gcc -S foo.c && cat foo.s'

Also, it struck me: why is /bin/sh a bad interpreter? Not present? bad chmod?

are you using multiple partitions?

I have this problem myself if I try to compile out of my "storage" partition. If I move the source back into my root partition, problem goes away. I've never really investigated it so I'm not sure what it is, but ( in my case) it must be something with how I'm mounting my storage partition

edit: My symptoms above were on multiple distro's

This problem can be caused by trying to execute code residing on a partition which has been mounted with 'noexec' set.
To check issue the mount command and check for the 'noexec' option against the partition your code is on :
e.g. etlnhl@Roland:~> mount
proc on /proc type proc (rw)
tmpfs on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
/dev/hda1 on /Data_120_C type reiserfs (rw,noexec,acl,user_xattr)

To fix, unmount the partition - umount /Data_120_C (make sure that nothing is using the partition i.e check that no shell or filemanager is currently open at a directory on that partition) and then remount it with the noexec option
e.g. etlnhl@Roland:~> mount /dev/hda1 /Data_120_C -o noexec

If you get an error such as the command complaining that you do not have permission or are not root then you will either have to mount the partition as root or change the /etc/fstab entry to include the option 'users'
Regardless you will need to edit your /etc/fstab file to create a permanent fix.

hope this helps.
