Description nick smethurst 2003-11-23 01:34:17 UTC

Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 3.3.1 
OS:          Linux

In auto project, if a project contains two libtool libraries and they are mistakenly crosslinked, KDevelop enters into an endless loop when the user types F7 to compile, and eventually crashes:

A bit of the resulting kdebug output (full directory paths not shown):

kdevelop (auto project):

and so on ..

Maybe there should be some kind of check for this user error which prevents the crash?

OK, I'll take a look at it

Comment 2 Amilcar do Carmo Lucas 2003-11-23 14:27:12 UTC

The problem is in the recursive function:
void AutoProjectPart::queueInternalLibDependenciesBuild(TargetItem* titem)
that starts around line buildtools/autotools/autoprojectpart.cpp:665 

The fix seams to be non trivial due to the async nature of the function.
Besides that we need to issue an error to the user, and we are currently in a string freeze, so I'll postpone this one for after the release.

Thanks for reporting.

Comment 3 Amilcar do Carmo Lucas 2004-01-21 15:10:37 UTC

Reopen, because the REMIND state "hides" the bug

Check for circular dependecies and tell the user if one is found.
