在linux上开发嘉楠耘智K210依赖库的问题

首先放出我IDE编译时出现的问题：

[ INFO] /home/wenhan/k210/KendryteIDE/LocalPackage/toolchain/bin/../libexec/gcc/riscv64-unknown-elf/8.2.0/cc1: error while loading shared libraries: libisl.so.19: cannot open shared object file: No such file or directory

这明显是k210的依赖库的问题，我就在~/.bashrc上添加了依赖库的路径 export LD_LIBRARY_PATH=路径，添加完毕之后，重新编译还是没有用。然后在换了一个 sudo vi /etc/profile 在这个文件下添加 LD_LIBRARY_PATH=$LD_LIBRARY_PATH:路径 export LD_LIBRARY_PATH 添加之后在终端输入 soucre /etc/profile 发现问题解决了。这应该是大部分编译C/C++依赖库的问题，因为我也用linux没多久，所以慢慢积累一些小问题的解决方式吧。
