Hi;
Gerbv PNG export is broken when cairo disabled.
How to reproduce:
1) configure with --disable-cairo option
2) load examples/dan/top.gbx
3) invoke File->Export->PNG
The result is segmentation fault. The cause is that
gerbv_render_to_pixmap_using_gdk() is called with selectionInfo
being NULL, whereas line 701,
if (selectionInfo->type != GERBV_SELECTION_EMPTY) {
relies on it's being non-NULL
I suggest to replace the line with
if (selectionInfo != NULL && selectionInfo->type != GERBV_SELECTION_EMPTY) {
This fixes the problem on all test I've run.
Regards,
Ineiev
