I added a KControl check box control for the shutdown feedback dialog. The one that says "Saving your settings" when logging out. The underlying support already existed. The check box merely adds a direct way for users to show or disable the dialog box. The patch provides nominal temporary relief against bug report 922: "When logging out with unsaved file, trinity does not ask to save it," (http://bugs.pearsoncomputing.net/show_bug.cgi?id=922). Currently the only solution to that bug is a work-around of disabling the feedback dialog. The patch is available through bug report 681 (http://bugs.pearsoncomputing.net/show_bug.cgi?id=681). Please test. Upon receiving a successful report I'll push to GIT. Thanks for helping. :) Darrell

gcc 4.7 template errors: a detailed explanation

by /dev/ammo42

There is an entry on Marshall Cline's C++ FAQ concerning the template constructs that generate new errors on G++ 4.7: http://www.parashift.com/c++-faq-lite/templates.html#faq-35.19 (see also the previous entry).

Updating mlt/mlt++ sources

by Darrell Anderson

Several days ago we discussed updating the mlt sources. I looked at that today. I need help knowing how to do this. 1. Many file differences and stupid git requires "git add" for new additions (but needs no help with deletions --- go figure). 2. mlt++ is now part of the mlt sources and would not need to be a separate libary in the source tree. 3. How to add the tqt layer to anything needing that if needed? I think only the qimage module is affected. qimage will know about Qt3 but not TQt3. 4. I'm still confused why we want to keep these sources in the tree when we do not provide anything needing them (unless kdenlive is ported). But I'll still try updating if provided sufficient information. Darrell

Bug 958 opened - gcc 4.7 build failures

by David C. Rankin

All, I have opened a bug for handling gcc 4.7 build failure issues: http://bugs.pearsoncomputing.net/bugzilla/show_bug.cgi?id=958 I have also uploaded a complete set of build logs for the packages listed as not building due to gcc 4.7 changes. I have set the priority to 'major'. Tim will need to determine if this is what it should be or whether it should be elevated for R14. Thankfully the packages that are affected is relatively small. Thus far: basket gwenview k3b kima kipi-plugins krusader python-tqt rosegarden tdebase ( now requires -fpermissive ) tdegames tdegraphics tdepim tdesdk The big issue is that distros that ship or update to 4.7 will not be able to build TDE until these issues are resolved. That eliminates Archlinux as the build environment updates to build on the current stable release of all packages (including gcc). Some build failures may be able to be handled by compiler/linker flags, where code changes will be required for the rest. The primary culprit seems to be gcc 4.7 implementation of additional features and extensions from C11 and C++11. The changes are summarized at: http://gcc.gnu.org/gcc-4.7/changes.html My guess for the lead suspect is: G++ now correctly implements the two-phase lookup rules such that an unqualified name used in a template must have an appropriate declaration found either in scope at the point of definition of the template or by argument-dependent lookup at the point of instantiation. As a result, code that relies on a second unqualified lookup at the point of instantiation to find functions declared after the template or in dependent bases will be rejected. The compiler will suggest ways to fix affected code, and using the -fpermissive compiler flag will allow the code to compile with a warning. template <class T> void f() { g(T()); } // error, g(int) not found by argument-dependent lookup void g(int) { } // fix by moving this declaration before the declaration of f template <class T> struct A: T { // error, B::g(B) not found by argument-dependent lookup void f() { g(T()); } // fix by using this->g or A::g }; struct B { void g(B); }; int main() { f<int>(); A<B>().f(); } That would explain my need to use -fpermissive to build tdebase last night where I never needed it before. Oh, well, the challenges of progress... Let's rip this apart and 'get her fixed' :) -- David C. Rankin, J.D.,P.E.

tdeedu gcc47 patch - signoff & push

by David C. Rankin

All, I was successful in developing a patch for the tdeedu package. It largely was another stl library vector with missing 'this->' prefixes in the class calls. tdeedu builds fine now! That's it for tonight. Now if I can just get a bit of help with tdepim, k3b, & digikam, we will be one to new packages... -- David C. Rankin, J.D.,P.E.

gcc47 - need help with tdepim - no real error - just huge cmake link output and crash

by David C. Rankin

All, Working with tdepim trying to solve the gcc47 issues, I'm stuck and don't really know where to start. I have the full build log at: http://www.3111skyline.com/dl/dt/tde/err/gcc47/tdepim/tde-tdepim-3.5.14_dev… I can't find and "error: whatever" to start with. All I get is this massive string of stuff and then the build fails. I saw something similar with tdegraphics that was solved with -fpermissive, but that didn't solve the tdepim issue. What to do next?
