The return value of dlopen() is a ``handle'' that should be considered an opaque value to be used by the other DL library routines. The simplest way is to set the LD_RUN_PATH environment variable when building software. This post describes how to debug some library dependency issues on a Linux machine. Documented those few variables that can be used to alter the installation tree structure in the install guide. However when RUNPATH is used, it does not. Mac or MonoMac The quick answer. There are a couple possible possible solutions : 1) when PR_LoadLibrary without a PATH fails, try again with a hard-coded PATH to the Sun absolute location (/usr/lib/mps ). Also dlopen ignores LD_LIBRARY_PATH as opposed to dlopen(3). In these examples, it is assumed that a standard development environment has been set up (system build tree, search path, boot and initialization of target machine). Warning: That file was not part of the compilation database. so does not dlopen liby. dlsym() The function dlsym () takes a "handle" of a dynamic library returned by dlopen () and the null-terminated symbol name, returning the address where that symbol is loaded into memory. o db | The UNIX and Linux Forums. rJava is often needed for tasks like reading Excel files or connecting to databases.

A quick fix for this is to revert to using the DT_RPATH attribute, which can be done by explicitly setting the --disable-new-dtags linker flag. The knobs I'm aware of are the DT_RPATH/DT_RUNPATH section in ELF, LD_LIBRARY_PATH, and system-wide config files. The segfault seems to happen only in combination with RPATH but we're not 100% sure if that is the only way to trigger this. I am experiencing different behaviours with MacOS and Linux.

A dynamic shared object (DSO) is an object file that is meant to be used simultaneously (or shared) by multiple applications (a. This is not because of this bug (easy enough to work around, just add -ldl to LDFLAGS), but because openssl, when configured without shared libraries, builds without -fPIC, which will cause linking errors on many Linux-based platforms. This handle is employed with other functions in the dlopen API, such as dlsym(3) , dladdr(3) , dlinfo(3) , and dlclose (). so, libclang_compiler.
