[Qt-creator] Slow cdb
Wasn't there a wiki entry about dead slow cdb or cdb in general? I think there was something related to the warning WARNING: Unable to verify checksum for ... but I couldn't find it any more. What was the reason for this warning, is this warning related to the slowdown? How could I fix the bad cdb speed on my installation side? (I use cdb to debug gdb support atm) Peter ___ Qt-creator mailing list Qt-creator@qt-project.org http://lists.qt-project.org/mailman/listinfo/qt-creator
Re: [Qt-creator] Slow cdb
Do you try to access global variables? I sometimes have a dead slow cdb too, if I try to access member / global variables that are out of scope. In this case, there are warnings in the debugger log that it can't access the variable. Once you run into this problem, the only solution is to re-start Creator (it seems the watched variable can't be removed) Andre Am 04.06.2013 09:40, schrieb Peter Kümmel: Wasn't there a wiki entry about dead slow cdb or cdb in general?

Re: [Qt-creator] Slow cdb
Hi Peter, the warning could result from using the Microsoft Symbol Server. The problem is that the cdb tries to get all your symbols from this server. What results in some overhead for all the symbols which are not available. For Example the whole Qt and QtCreator libraries. If you have a Creator checkout from the 2.8 branch you schould be able to add a symbol cache to the symbol paths for the cdb in the options under Debugger - CDBPaths - Symbol Paths - Insert... - Symbol Cache... It is important that you insert the cache before the symbol server otherwise the symbols wouldn't get cached and read before the server is contacted. If you are using an older QtCreator add the symbolcache manually. The setting can be found under Options - Debugger - CDB - Paths - Symbol Paths - Edit... in versions 2.8. For Example: cache*C:\dev\symbolcache srv*http://msdl.microsoft.com/download/symbols You should also remove the folder from the path with srv*. Otherwise The symbols from the server would be cached in two places. BR David Am 6/4/2013 9:40 AM, schrieb Peter Kümmel: Wasn't there a wiki entry about dead slow cdb or cdb in general?

But I couldn't test with Creator and qbs, because 2.8/qbs build is broken: ..\diffeditoreditable.cpp': No such file or directory Peter ___ Qt-creator mailing list Qt-creator@qt-project.org http://lists.qt-project.org/mailman/listinfo/qt-creator
