I want to execute a c++ program that starts 2 sub-programs. The problem is, that one program needs another library path as the other program. So I have something like this: -_Parent program execution --->setting LD_LIBRARY_PATH-> Execute first child program --->setting LD_LIBRARY_PATH new -> Execute second child program

How can I achieve that (or isn't this possible at runtime?). Thanks in advance!

  • You can append more than one path with the `LD_LIBRARY_PATH` flag. Or am I missing what you're asking? – Tyler Jandreau Feb 04 '14 at 15:53
  • The problem is, that i need in the path one library, but with two different compile options. If I append them both in the LD_LIBRARY_PATH, my programs will chose always the first. But I want program A to chose the libraryXa and program B libraryXb. LibraryX can only be compiled to support C++ OR CUDA, but not both -.- , and one program needs the library with C++ support, the other the same library with CUDA support. That's why I have to do this like this. Hope this makes it more clear. – user2835278 Feb 04 '14 at 15:58
  • Yes, that does, however, I have no idea how to fix that. Sorry! – Tyler Jandreau Feb 04 '14 at 16:01
