I have the same problem. On old version of Ubuntu our own and other projects from the web properly compile, link *and* run. The same is true using all other systems we have tested, openSUSE up to 13.1, different Red Hats, Fedoras, Angstroem, Debian (RaspberryPi).
But with Ubuntu 14.04.2 LTS it doesn't work any more. When I install the original libtool 2.4.2 from the GNU sources on Ubuntu 14.04.2 LTS everything is fine and back to normal. Just setting link_all_deplibs to yes didn't help too much. Linking wasn't a problem, but we had unresolved externals when trying to run binaries, and ldd didn't show the dependencies as well, allthough libtool linked the appropriate libs, probably missing some rpath statements (?). Changing all autotool files of all our projects, or as a maintainer in the sources from the web is quite some work. And the manual maintenance of the nested dependencies in other libs or executables is not very efficient and redundant work. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libtool in Ubuntu. https://bugs.launchpad.net/bugs/1002565 Title: Libtool fails to handle library interdependencies Status in libtool package in Ubuntu: New Bug description: Libtool fails to handle library interdependencies. The interdependency is specified on the command line, and is recorded correctly by libtool, however, since there is no dependency from the point of view of the binary library files, and since libtool no longer adds all dependency libraries on the command line, compiling of the final application fails. I suppose the problem is that libtool has been changed to set link_all_deplibs=no on my platform, but I'm not sure. Here is an example that illustrates the problem: ### create test files: cat >alpha.hpp <<EOI void alpha(); EOI cat >alpha.cpp <<EOI #include "alpha.hpp" void alpha() {} EOI cat >beta.hpp <<EOI #include "alpha.hpp" void beta1(); inline void beta2() { alpha(); } EOI cat >beta.cpp <<EOI #include "beta.hpp" void beta1() {} EOI cat >app.cpp <<EOI #include "beta.hpp" int main() { beta2(); return 0; } EOI ### build 'libalpha': libtool --tag=CXX --mode=compile g++ -c alpha.cpp libtool --tag=CXX --mode=link g++ alpha.lo -o libalpha.la -rpath /tmp ### build 'libbeta': libtool --tag=CXX --mode=compile g++ -c beta.cpp libtool --tag=CXX --mode=link g++ beta.lo libalpha.la -o libbeta.la -rpath /tmp # Depends on 'libalpha' ### build app: libtool --tag=CXX --mode=link g++ app.cpp libbeta.la -o app ### error: # In function `beta2()': # app.cpp: undefined reference to `alpha()' ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: libtool 2.4.2-1ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-24.38-generic 3.2.16 Uname: Linux 3.2.0-24-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.0.1-0ubuntu7 Architecture: amd64 Date: Tue May 22 00:37:22 2012 InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) ProcEnviron: LANGUAGE=en_US:en TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: libtool UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libtool/+bug/1002565/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
