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] $./svict/svict -i sim.75.sorted.bam -r /data/ref_data/GATK_bundle/hg38/hg38.fasta -o out ./svict/svict: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by ./svict/svict) ./svict/svict: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by ./svict/svict) ./svict/svict: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ./svict/svict) 这个错误是目前的libstdc++.so.6没有对应的GLBCXX造成的。可以通过如下命令查看： [me@node1 svict]$ strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBCXX_3.4.14
GLIBCXX_3.4.15
GLIBCXX_3.4.16
GLIBCXX_3.4.17
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
[root@node1 svict]# find / -name libstdc++.so.6*
