compiling [message #647]

Hi,

Using centos-default I add the gcc, cpp, glibc-devel and other dependant rpms.

However gcc will not build anything. It errors with:

bash-3.00# gcc test.c
collect2: cannot find `ld'

ld exists and is in the path:

bash-3.00# ld
ld: no input files

any ideas?

Thanks!

I have checked /proc/user_beancounters and nothing is going over.

I also created a fedora core 4 ve, did :

yum install gcc

and it too has the same compile error.

Any ideas - this is driving me crazy Smile

do you use EMT64 arch?
maybe you installed 32bit ld, so gcc can't find the appropriate 64bit. or vise versa.
send me credentials via email if want some help.

so everything is 32bit?
then send me a dump of `strace -f -o dump gcc test.c` please
or give me credentials to the VPS. I'm sure, it's something simple Smile

The output is very large so I am trying to cut it down some.

I did find it is something to do with linking:

gcc -c test.c

works and produces test.o

What packages install the linker? I think I have them all installed but I must not!

Thanks again

try to find out from strace output what was doing gcc before it printed that it failed. this is a clue. it will be visible that it looks for some file or something like that. after that you can check to which RPM this file in question belongs to and install the required packages.

The command line result is:

bash-3.00# gcc test.c
collect2: cannot find `ld'

test.c is :

main(){return(0);}

ok, i fixed it.

classic operator error!

my path was not set. I could have SWORN I checked it first thing since that would be an obvious reason that ld could not be found.

Anyway fixed now. Argggg....

Hi,

Thanks again for your help! Smile

As a reminder to anyone who may be reading this in the future - if you vzctl into a ve I don't think it sets the same environment as if you ssh'd in.

This was the main cause of my problem.

Also, don't forget to export your PATH after you set it.

I think what I was doing was:

using vzctl to enter the VE
try to complile
gcc can't find ln
checking path
no path
setting path
FORGETTING TO EXPORT PATH!!!
still no worky

exporting my path or ssh'ing in proper fixed it.

Anyway, I hope this may help someone who has the same problem in the future.
