Hey gang,

I'm messing with camstream again now that it's being worked on again, and had to install an old verion of qt (qt-2.3.2 to be exact) alongside my 9.2 stock qt3. The latest snapshot of camstream compiled just fine, no errors (that I saw), and during configure I told it where to find the old qt version to use. When I do ./camstream though, I get this error:

./camstream: error while loading shared libraries: libqt-mt.so.2: cannot open shared object file:No such file or directory

How about LD_LIBRARYPATH? Did you append the location of your old qt version there?

Dmitry

I don't understand what that means. I've seen it in the --help part of configure, but don't have a clue what it means or what I should do with it. Can I ask you to explain in simple terms, or just tell me what I should do?

LD_LIBRARY_PATH is a colon-separated list of directories in which to search for libraries at execution-time. When runtime linker needs to load a shared library, it uses the value of this environment variable to determine a search order (it uses other env. variables as well, for complete list do man ld.so) So for you in order to use old qt libraries is necessary to append their path at the beginning of the LD_LIBRARY_PATH env. variable. Hope it helps Dmitry

Thanks for any help.
