- Subject: how to get my app to find a dynamic library
I'm using Cygwin on Windows XP. gcc version 3.4.4.
My main app 'main.c' is in one directory and I have a dynamic library
'cygmylib.dll' in a subdiretory 'tmp'. I can compile and link my main
app fine but having trouble running it. It complaints about not being
able to find the dynamic library. I have tried just about everything
from -L, -Wl,-rpath using relative or absolute paths on the compile line
to setting LD_LIBRARY_PATH and LD_RUN_PATH at run time, but to no avail.
Here is how I link:
gcc -o app main.c -Wl,-rpath tmp/ -Ltmp/ -lmylib
If I run from the same directory, it cannot find the dynamic library.
If I cd to tmp and run it like ../app it does run fine and finds the
dynamic library, but this is not how I want to use it.
Is there a special link option I need to use? What is the magic?
Thanks.
