With this option, the dynamic libraries are only linked in if the linker sees a need for them. So library names *must* be passed in strict use order, i.e. a library containing symbols must come after the one that needs it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

While building with osc, some modules link with wxWidgets libraries, but don't use the -rpath. As a consequence, the resulting module cannot find wxWidgets libraries. Now I have to check, why it is happening. All variables seems to be set properly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=690952 https://bugzilla.novell.com/show_bug.cgi?id=690952#c6 --- Comment #6 from Stanislav Brabec 2011-05-13 14:53:49 CEST --- On my machine, even x86_64 packages exhibit the problem and three modules fail to load. I found an apparent linking definition bug in the codeblocks code: Libraries in src/plugins/contrib/wxSmith/wxwidgets apparently use wxWidgets, but they don't define dependency on wxWidgets. They include reference to src/sdk/libcodeblocks.la which link to wxWidgets. As the consequence, references to wxWidgets are evaluate correctly (it links even with a strict -no-undefined linking policy), but the linking infrastructure (libtool & co.) don't pass the required -rpath. As a consequence, these libraries are not able to find wxWidgets libraries. Here is my theory, why it exhibits problem only with -as-needed: The whole application probably links with all wxWidgets libraries without -as-needed. The library module inherits references to wxWidgets from the application. With -as-needed this does not happen. I have to check, whether it is only a bug of codeblocks (which is apparent), wxWidgets (extra option needed for -rpath inheritance?) or even libtool. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=690952 https://bugzilla.novell.com/show_bug.cgi?id=690952#c8 --- Comment #8 from Stanislav Brabec 2011-05-16 21:52:08 CEST --- I finally see, where is the problem and how to fix: Affected third party packages use libtool to link libraries. libtool has its own heuristic, which decides, whether -Wl,-rpath should be included. The libtool heuristic fails here. This heuristic uses .la files. But wxWidgets libraries are not linked by libtool, and no .la files exist there. wx-config explicitly provides -Wl,-rpath. It is used by the libraries directly linked against wxWidgets (and this linking succeeds), but their .la file does not store -Wl,-rpath. Second level libraries or binaries that link against these first level libraries are linked with wxWidgets again (however it makes no sense in a modern GNU-Linux system, it is a standard libtool behavior), but as the .la file does not contain -Wl,-rpath information, the inherited -Wl,-rpath are not added to LDFLAGS. Linking succeeds, but runtime is not able to find libraries. I see two possible fixes: 1. Fast and easy: Create syntethic .la files for wxWidgets libraries to work-around linking problem. 2. Complex: Learn libtool to be smarter if .la file does not exist.

To Neil Darlow (comment 9): 1) As long as codeblocks uses wx-config (and it uses), it should be always OK. 2) Bootstrapping will always need Makefile-based build. In fact, codeblock just correctly uses libtool (well, not completely correctly, see comment 6). But the libtool does incorrect thing - it passes wxWidgets libraries to the third level libraries/binaries linker but does not inherits linking flags needed to link against xWidgets libraries. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
