... because the file system is not case sensitive and the subdirectory location exists in the build directory. If you follow the description from the README.md to include Location in your own project everything should be fine.

Details:

ld: can't open output file for writing: Location, errno=21 for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

How to fix:
Use a different name (other than Location) in Location/CMakeLists.txt, e.g.

...
add_executable(LocationTest main.cpp)

target_link_libraries(LocationTest Location_math)
target_link_libraries(LocationTest Location_models)
target_link_libraries(LocationTest Location_location)
target_link_libraries(LocationTest Location_sensor)
target_link_libraries(LocationTest Location_system)
target_link_libraries(LocationTest Location_utils)
target_link_libraries(LocationTest Location_test)

Builded apk with android studio. With BlueStacks 5.5.101.1002 it start's up.
Maybe someone could do some updates for this project?

您好，想求教几个API调用的问题：
1、在安卓开发中，该如何调用该项目API呀？
2、输出的经纬度需要是WGS_84格式的吗？

This project does not have an open source license. This makes the project nearly impossible to use under US intellectual property laws. Please choose one of the standard open source licenses and add it to your project. (GitHub has built-in functionality that makes this easy to do.)

If you are looking for pointers, I would suggest the BSD-3-Clause or Apache licenses. I would avoid the LGPL, GPL, and AGPL, because they make your code difficult to use for many organizations.

您好！
想请教下二阶低通滤波器参数计算公式的推导过程，查阅相关滤波器设计的资料，发现无法推导出你在代码中实现的参数公式，请问您是如何推导而来的，有相关参考资料吗？
望不吝赐教！谢谢！！

您好 ，我看到您对通过imu和gps传感器模拟定位有很多经验 ，我有一个问题很困扰想从您这得到帮助。
我是游戏开发工程师 ，希望通过手机的imu和gps模拟手机的姿态和位置出现在unity(游戏引擎)中的地图上行驶。 但是我根据imu的横摆角来模拟时和gps经纬发生了很大的偏离 ，您是否有使用gps来纠正imu yaw角 来修正朝向的经验？ 我希望能够及时的响应imu的朝向 ，但不要偏离gps位置太多 。

黄色箭头是gps位置，红色箭头是根据imu航向和速度模拟的，朝向偏差导致分道扬镳了。

The project is very referential and the code annotation is complete. how to get the sensor data required by the project with mobile phone? Or what devices do you need to buy to collect sensor data?

你好，想问一下关于测试算法的几个问题
1.手机需要固定的很好吗，是不是竖直手机放置就行了
2.在测试时候发现，算法在gnss失锁了的话，惯导就很快会发散了，不知道作者您是否也是同样的情况。
