rpath

I'm aware that it is possible to use readelf -d <elf> | grep RPATH to inspect a given binary from the shell, but is it possible to do this within a process? Something like (my completely made up system call): /* get a copy of current rpath into buffer */ sys_get_current_rpath(&buffer); I'm trying to diagnose some suspect SO linking issues in our codebase, and would like to inspect the RPATH this way if possible (I'd rather not have to spawn an external script). Employed Russian #include <stdio.h> #include <elf.h> #include <link.h> int main() { const ElfW(Dyn) *dyn = _DYNAMIC; const ElfW(Dyn)

I have Ubuntu 14.04. It came with openssl 1.0.1f. I want to install another openssl version (1.0.2) and I want to compile it by myself. I configure it as follows: LDFLAGS='-Wl,--export-dynamic -L/home/myhome/programs/openssl/i/lib -L/home/myhome/programs/zlib/i/lib' CPPFLAGS='-I/home/myhome/programs/openssl/i/include -I/home/myhome/programs/zlib/i/include' ./config --prefix=/home/myhome/programs/openssl/i \ zlib-dynamic shared --with-zlib-lib=/home/myhome/programs/zlib/i/lib \ --with-zlib-include=/home/myhome/programs/zlib/i/include make make install After install, when i check the binary with

For convenience I added the relevant manpages below. My (mis)understanding first: If I need to separate options with , , that means that the second -Wl is not another option because it comes before , which means it is an argument to the -rpath option. I don't understand how -rpath can have a -Wl,. argument! What would make sense in my mind would be this: -Wl,-rpath . This should invoke -rpath linker option with the current directory argument. man gcc: -Wl,option Pass option as an option to the linker. If option contains commas, it is split into multiple options at the commas. You can use this
