Hi,
I have got a program using plplot wxwidgets and opencv on windows and
linux mint.
I use valgrind to check memory on linux. I have got some memory leak
(definitely lost) :
==19342== 128 bytes in 13 blocks are definitely lost in loss record
14,252 of 17,211
==19342== at 0x4C2935B: malloc (vg_replace_malloc.c:270)
==19342== by 0x1008661F: rdbuf_text (in
/usr/local/lib/libplplot.so.12.0.1)
==19342== by 0x10085FBC: rdbuf_esc (in
/usr/local/lib/libplplot.so.12.0.1)
==19342== by 0x10086A9C: plbuf_control (in
/usr/local/lib/libplplot.so.12.0.1)
==19342== by 0x100869B9: plRemakePlot (in
/usr/local/lib/libplplot.so.12.0.1)
==19342== by 0x10057EC3: c_plreplot (in
/usr/local/lib/libplplot.so.12.0.1)
==19342== by 0xB8146F5: plstream::replot() (in
/usr/local/lib/libplplotcxx.so.11.0.0)
==19342== by 0xB5FE151: wxPLplotstream::RenewPlot() (in
/usr/local/lib/libplplotwxwidgets.so.0.0.0)
==19342== by 0xB6001FE: wxPLplotwindow::RenewPlot() (in
/usr/local/lib/libplplotwxwidgets.so.0.0.0)
==19342== by 0x495D04: FenetreCoupe::Plot(bool) (in
/home/lb/Documents/wxOpenCV/wxOpenCVMain/wxOpenCVMain)
==19342== by 0x4B70E0: ImageStatistiques::MAJCoupe(wxRect&) (in
/home/lb/Documents/wxOpenCV/wxOpenCVMain/wxOpenCVMain)
==19342== by 0x48737B: ZoneImage::OnLeftButtonUp(wxMouseEvent&) (in
/home/lb/Documents/wxOpenCV/wxOpenCVMain/wxOpenCVMain)
My code to plot the curve is here
perso.univ-lemans.fr/~berger/Afsd56/FenetreCoupe.cpp and sa screencopy
of the curve perso.univ-lemans.fr/~berger/Afsd56/copie.jpg
Is it really a memory leak ? If yes Have you got any idea to solve this
problem?
Thanks you for your answer.
