开源目的

鉴于rtklib的巨大的时间更新间隔，作者在github上fork了一个仓库，初步用于以下目的，

修复代码中的bug/issue
对代码或者结构进行尽可能小的调整或者优化,程序性能提升，编译器，操作系统支持等
算法性能的提升或优化
建立一个rtklib的wiki

目前的工作

目前已经进行了部分更行，此部分更新暂时位于分支cmake_support，等待cmake的support全部完成后，会merge到master分支
https://github.com/akstuki/RTKLIB_improve/tree/feature/cmake_support

在目前的cmake_support分支中主要修复了以下两个bug,

关于windows下路径下文件读取的bug，windows实际上是支持路径分隔符/的，但在原代码中必须使用\\
修复了一个单点定位程序debug下的bug

另外，此分支主要致力于将app下的程序对编译器的依赖抽离出来，使用CMake重新组织代码，这样我们可以有更好的跨平台和多编译器支持，现在rnx2rtkp的support已经完成，并分别在Windows和Linux下进行了测试。

使用

下边简单介绍一下cmake 对 rnx2rtkp的support，以linux为例，windows是一样的，

首先，我们使用以下命令生成makefile，以下命令要在目录rtklib_improve/app/consapp/rnx2rtkp下执行，

$ cmake -S . -B binn

上述命令的输出大概是下边的样子，

-- The C compiler identification is GNU 11.2.0
-- The CXX compiler identification is GNU 11.2.0

-- Build files have been written to: /cygdrive/c/xq/1-own/0-code/0rtkapps/rtklib_improve/app/consapp/rnx2rtkp/binn

编译程序
执行以下两行命令，
cd binn
make

在windows下如果我们安装了visual studio，那么第一步会在binn文件夹下生成visual studio的工程文件，我们使用visual studio打开文件编译即可

编译输出很可能看起来是下边的样子，

编译成功，我们查看以下当前目录，发现可执行程序已经生成了，

$ ls
CMakeCache.txt  CMakeFiles  CTestTestfile.cmake  Makefile  cmake_install.cmake  rnx2rtkp.exe

run test
我们通过以下命令run以下test，
make test
输出大概是下边的样子，

$ make test
