From: "vz-gdb at zeitlins dot org" <sourceware-bugzilla@sourceware.org> To: gdb-prs@sourceware.org Subject: [Bug c++/9541] Bogus "warning: can't find linker symbol for virtual table for 'Foo' value" messages Date: Thu, 29 Nov 2012 20:03:00 -0000 [thread overview] Message-ID: <bug-9541-4717-TnUvWkFM9y@http.sourceware.org/bugzilla/> (raw) In-Reply-To: <bug-9541-4717@http.sourceware.org/bugzilla/> http://sourceware.org/bugzilla/show_bug.cgi?id=9541 --- Comment #4 from vz-gdb at zeitlins dot org 2012-11-29 20:03:04 UTC --- I can confirm that the problem still exists with 7.5.50.20121129-cvs version (built from sources without any special configure options under bog standard x64 Debian system). I didn't see it with wxWindow yet but just showing the value of some random window pointer I see the following: (gdb) p *this $4 = (wxNumberEntryDialog) { <wxDialog> = { <wxDialogBase> = { <wxTopLevelWindow> = { <wxTopLevelWindowGTK> = { <wxTopLevelWindowBase> = { <wxNavigationEnabled<wxNonOwnedWindow>> = { <wxNonOwnedWindow> = { <wxNonOwnedWindowBase> = { <wxWindow> = { <wxWindowBase> = { ... m_font = warning: can't find linker symbol for virtual table for `wxFont' value { <wxFontBase> = { <wxGDIObject> = { <wxObject> = { _vptr.wxObject = 0x67e510 <_ZTV6wxFont@@WXU_2.9+16>, m_refData = 0x0 }, }, }, }, m_backgroundColour = warning: can't find linker symbol for virtual table for `wxColour' value { <wxColourBase> = { <wxGDIObject> = { <wxObject> = { _vptr.wxObject = 0x67b330 <_ZTV8wxColour@@WXU_2.9+16>, m_refData = 0x0 }, }, <No data fields>}, }, ... (gdb) p this->m_font $5 = warning: can't find linker symbol for virtual table for `wxFont' value warning: can't find linker symbol for virtual table for `wxFont' value { <wxFontBase> = { <wxGDIObject> = { <wxObject> = { _vptr.wxObject = 0x67e510 <_ZTV6wxFont@@WXU_2.9+16>, m_refData = 0x0 }, }, }, } AFAICS there is absolutely nothing special about wxFont and wxColour classes compared to many others that it doesn't seem to have problems with. Please let me know if there is anything else I can do to help finding this bug. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
