[Bug 1804762] Re: libomp5 packaging problem: *.so are in -dev package
Ok, I got it. In my case error was thrown by libmkl_intel_thread.so, it dlopen() libiomp5.so. This thread describes the reason: https://software.intel.com/en-us/forums/intel-math-kernel-library/topic/402497 So I chose the wrong package, must be libmkl-rt. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1804762 Title: libomp5 packaging problem: *.so are in -dev package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openmprtl/+bug/1804762/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1804762] Re: libomp5 packaging problem: *.so are in -dev package
Hi! I'm asking for the details because I think they do matter. It could be that the problem is resolved by changing your link flags. Libomp's packaging looks to be arranged in the correct way. The -dev package contains files ending in .so. Those are symbolic links to a file ending in .so.5 that is contained in the libomp5 package. Usually a compiled program only requires the .so.5 file to be present. This is how it's described in Debian policy: https://www.debian.org/doc/debian- policy/ch-sharedlibs.html My perception is that when I link a program with -liomp5, I get this dependency: "libomp.so.5 => /usr/lib/x86_64-linux-gnu/libomp.so.5 (0x7f78ae8b2000)". Because *.so in -dev package is usually the correct thing to do in Ubuntu, I believe your conclusion that the packaging is wrong, might not be true.

Hi! This doesn't really matter. I'm building dlib (http://dlib.net/) with Intel MKL libraries. One of them loads libiomp5.so dynamically and that causes "undefined symbol" error.

Hi, please provide some information about your library and application. What is the linker command to produce the application? What is the full output of your failing application? What does ldd tell about your executable? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1804762 Title: libomp5 packaging problem: *.so are in -dev package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openmprtl/+bug/1804762/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
