程序使用libstdc++库文件偏低及解决方案

./svict -i sim.75.sorted.bam -r /data/ref_data/GATK_bundle/hg38/hg38.fasta -o out

运行svict报错
[me@node1 svict] strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2

GLIBCXX_3.4.18
GLIBCXX_3.4.19
GLIBCXX_DEBUG_MESSAGE_LENGTH
可以看到，最高版本为3.4.19，没有对应的3.4.20。

通过查看libstdc++.so.6可以看到它链接到了另外一个库
[me@node1 svict]$ ll /usr/lib64/libstdc++.so.6
lrwxrwxrwx. 1 root root 19 3? 10 11:43 /usr/lib64/libstdc++.so.6 -> libstdc++.so.6.0.19

接下来看看系统还有没有更高版本的lib库
