在linux用gdb或者cgdb计较不爽的地方是无法打印STL的东西,所有啊去网上找了找解决方案 https://www.douban.com/note/182826844/?qq-pf-to=pcqq.c2c
本帖把怎么配置这个东西写出了,万一以后忘了,可以回头找找。
首先是下载gdb文件 https://sourceware.org/gdb/wiki/STLSupport ------》找到网页里面的
然后点击进去下载stl_views_1.0.3.gdb
接下来把这个东西当到linux下,位置随便放,我放到了我的用户目录下
然后写一个小程序测试一下,
接着cgdb test 进入调试模式,然后加载刚才的stl_views_1.0.3.gdb
接着就可以看看pmap的命令了
pmap variable------------>打印variable这个map的定义和map里面的个数
pmap variable int int(就是单纯的两个int) ------------>打印pmap的元素和map的个数
pmap variable int int 20------------>打印索引是20的map的值 和map的个数
pmap variable int int 20 200------->打印索引是20 值是200的map值和map的个数
东西很好用,就怕以后链接失效找不到这个文件了,下面会把这个文件东西拷贝在下面。以后用到了,自己建立一个stl_views_1.0.3.gdb,然后把下面的东西拷贝进去使用。
