注意，最新开发版本的代码不稳定，存在问题，以下的仅仅是记录自己的操作过程，代码并不能正常工作。正常使用的话，请不要使用如下的版本操作。
参考ubuntu 16.04系统LimeSDR V1.4使用OpenAirInterface搭建LTE实验环境，并参考 解决ubuntu 16.04系统上2017.06版本之后的LimeSDR V1.4驱动不能正常运行OpenAirInterface搭建的LTE实验环境的问题使用最新的LimeSDR驱动能正常进行LTE实验之后，我们开始尝试把OpenAirInterface的代码更新到最新版本（2018_w15),新版本的代码结构更加清晰，但是不可用。

另外，最新版本运行的时候如果增加-d参数，启动图形界面，程序会崩溃。目前这个版本可以运行，但是貌似会导致LimeSDR驱动数据发送异常，目前已知，这个版本的驱动没有正确的读取配置文件，导致给硬件的配置信息是错误的，暂时这个版本还不可用。
您好前辈 limesdr usb 什么固件比较好用 升级新固件后之前gnuradio和好多东西都不能用了，新固件问题多 那个最新版本稳定
v17.06.0 版本稳定性不错，不过，目前我这边测试最新的代码是没有问题的，就是启动的时候比较慢，一般解决方法是外接 9V-12V的直流电源来解决启动问题。
前辈你好
sed -r -i "s/first_rx[ \t]*=[ \t]*1;/first_rx = 0;/g" targets/ARCH/LMSSDR/USERSPACE/LIB/lms_lib.cpp s
报错说没有这个文件 还有 source oaienv 这个也是 一样报错
版本，请注意代码版本，git clone 下来，默认是最新版本，请切换到我使用的版本，编译通过之后，再切换到最新版本上试试。这样调整比较快
source oaienv 说没此文件
不清楚你是什么意思。
