Why is there no library on the LD LIBRARY PATH?

Why is there no library on the LD LIBRARY PATH?

It is possible that despite LD_LIBRARY_PATH, a library is not found because of ABI mismatch. Note also that languages (like Perl and Python) and packages may have their own system of libraries (possibly also with .so files), unrelated to LD_LIBRARY_PATH.

How to find multiple directories in LD LIBRARY?

Multiple directories can be listed, separated by a colon (:), and this list is then searched before the compiled-in search path (s), and the standard locations (typically /lib, /usr/lib, …). testing new versions of a shared library against an already compiled application

Is there a Perl script for LD LIBRARY PATH?

Note: pldd is originally a Solaris command, that usually is not available on Linux. However, there is a Perl-script available (and installed on our machines) that extracts this information from the /proc/ /maps file. How to avoid those problems with LD_LIBRARY_PATH? A very simplistic answer would be: “just don’t use LD_LIBRARY_PATH!”

What should I do if I get library error?

If the library error is when you actually run the compiled program then you need to add the library path to /etc/ld.so.conf and run ldconfig to rebuild the library search path cache. Thanks for contributing an answer to Unix & Linux Stack Exchange!

How to tell the linker where to find libraries?

It is not consulted at link time (except maybe for locating libraries required by the built tools themselves!). In order to tell the linker where to find libraries at build time, you need to use the -L linker option. You already did that too: If you are still getting the error, then you need to make sure that the library is actually there.

How to tell the linker where to find libraries at build time?

You already did that too: If you are still getting the error, then you need to make sure that the library is actually there. Do you have a file libboost_regex-mt.so or libboost_regex-mt.a in that (or any) directory?
