Bug #: 15190
Summary: programs run inside gdb ignore LD_LIBRARY_PATH
Product: gdb
Version: 7.2
Status: NEW
Severity: normal
Priority: P2
Component: cli
AssignedTo: unassigned@sourceware.org
ReportedBy: lvernschrock@gmail.com
Classification: Unclassified
This looks very similar to bug # 9011. I think that the easiest way to discuss
this is to simply paste my shell output in the bug report:
[quote]
tc@box:~$ cat > awsome.h << EOF
> void printmessage();
> EOF
tc@box:~$ cat > awsome.c << EOF
> #include "awsome.h"
> #include <stdio.h>
>
> void printmessage(){
> printf("your computer is awsome\n");
> }
> EOF
tc@box:~$ mkdir mylib
tc@box:~$ gcc -fPIC -c awsome.c -o awsome.o
tc@box:~$ gcc -shared awsome.o -o mylib/libawsome.so
tc@box:~$ cat > demo.c << EOF
> #include "awsome.h"
>
> int main(int argv){
> printmessage();
> return 0;
> }
> EOF
tc@box:~$ gcc -c demo.c -o demo.o
tc@box:~$ gcc demo.o -Lmylib -lawsome -o demo
tc@box:~$ ./demo
./demo: error while loading shared libraries: libawsome.so: cannot open shared
object file: No such file or directory
tc@box:~$ export LD_LIBRARY_PATH=~/mylib
tc@box:~$ ./demo
your computer is awsome
tc@box:~$ gdb demo

What really bothers me is the output from "show env LD_LIBRARY_PATH".
It seems that gdb sees the environmental variable; why can't the program inside
see it?
I'm running on a Linux-based O.S.; kernel version 3.0.21.
P.S. I don't actually want to debug this demo program. I'm trying to debug a
more complex program and I wrote this trivial example to illustrate the issue
I'm running into.

Not reproducible for me (Fedora 17 x86_64):
$ echo $LD_LIBRARY_PATH

Could it be something in your shell's config clearing the environment?
GDB runs the program like "exec $SHELL -c program".

Okay, it is defiantly a problem with my shell configuration.

tc@box:~$ export LD_LIBRARY_PATH=/home/tc/mylib
tc@box:~$ echo $LD_LIBRARY_PATH
/home/tc/mylib
tc@box:~$ $SHELL
tc@box:~$ echo $LD_LIBRARY_PATH
tc@box:~$ exit
tc@box:~$ echo $LD_LIBRARY_PATH
/home/tc/mylib
[/quote]
Thus I assume that this is an invalid bug. I'll mark it as a duplicate of bug#
9011.
