View Full Version : LD_LIBRARY_PATH Question
January 29th, 2005, 11:40 PM
Does the LD_LIBRARY_PATH environment variable work in Ubuntu similar to how it does in other distros? I have previously worked with both Debian an Mandrake 9.2, and exporting this variable would cause my programs to search the paths I gave for shared libraries. I've tried the same trick with Warty, but it doesn't seem to work. sym-linking the library into /usr/lib seems to work, but I hate to keep reaching for sudo all the time. Any thoughts?

I just tried ldd with a modified LD_LIBRARY_PATH, and it displays the expected thing, and strace reveals it opening the correct file in my LD_LIBRARY_PATH. What evidence do you have that it doesn't work?

I downloaded and compiled a side scrolling game called "Holtz's Castle", which creates an executable and a library. The library installs itself in /usr/local/lib. I tried setting my LD_LIBRARY path to that directory, but kept getting an error that the library failed to load.
Dunno what I was doing wrong (maybe a typo?), but I tried it a couple times before posting. Tried again after reading your reply, and it works fine now. I must have just been doing something silly (maybe two different shells open and I didn't notice I exported in one and tried to run in the other.
Anyway, thanks for your help.
