collect2: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.

请问这是因为环境版本不匹配还是因为什么啊？

@AndroidLwk 少链接库了，sample::splitToStringVec找不到

[sang8052]

我也遇到了这个错误，现在已经解决。已经请求合并fix
问题是作者使用的是 tensorrt 8.4.2.4 ， 在 版本号 >= 8.4.2.4 (具体未知)的 tensorrt 中，将 splitToStringVec 放在了 samples/common/sampleUtils.h 因此缺少了依赖，请求修正
