From: "lvernschrock at gmail dot com" <sourceware-bugzilla@sourceware.org> To: gdb-prs@sourceware.org Subject: [Bug cli/15190] New: programs run inside gdb ignore LD_LIBRARY_PATH Date: Sun, 24 Feb 2013 21:49:00 -0000 [thread overview] Message-ID: <bug-15190-4717@http.sourceware.org/bugzilla/> (raw) http://sourceware.org/bugzilla/show_bug.cgi?id=15190 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 GNU gdb (GDB) 7.2 Copyright (C) 2010 Free Software Foundation, Inc.

(gdb) show env LD_LIBRARY_PATH LD_LIBRARY_PATH = /home/tc/mylib (gdb) quit [/quote] 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. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
