如何定位segment fault发生的位置(wgdi)

Question

我试过运行wgdi -d grape.total.conf，显示是这样的：

blast  =  grape.blast.txt
gff1  =  grape_Chr_uniq.gff
gff2  =  grape_Chr_uniq.gff
lens1  =  grape_Chr.len
lens2  =  grape_Chr.len
genome1_name  =  Vitis_vinifera
genome2_name  =  Vitis_vinifera
multiple  =  1
score  =  100
evalue  =  1e-5
repeat_number  =  10
position  =  order
blast_reverse  =  false
ancestor_left  =  none
ancestor_top  =  none
markersize  =  0.5
figsize  =  10,10
savefig  =  grape.dot.png
failed to get the current screen resources
Segmentation fault (core dumped)

我运行 gdb core.76309 :

我应该如何查明错误的位置？

Answer 1

gdb core.76309

这是错误的命令。相反，这样做：

gdb wgdi core.76309
