本文档详细介绍了如何在使用Eigen3.4.0时屏蔽大量编译警告，包括修改Eigen源文件、创建构建目录、配置CMake并安装，以及在CMakeLists.txt中添加相关路径。通过这些步骤，可以避免在开发过程中因Eigen库引发的警告干扰。

屏蔽Eigen大量警告

1.下载eigen3.4.0
2.
	cd eigen-3.4.0
	vi Eigen/src/Core/util/DisableStupidWarnings.h 修改成如下部分
	
	#elif defined __GNUC__
	  #pragma GCC diagnostic ignored "-Wdeprecated-declarations"
    #pragma GCC diagnostic ignored "-Wdeprecated-copy"
    #pragma GCC diagnostic ignored "-Wint-in-bool-context"
    #pragma GCC diagnostic ignored "-Wint-in-bool-context"
    #pragma GCC diagnostic ignored "-Wmisleading-indentation"
    #pragma GCC diagnostic ignored "-Wdeprecated"
    #pragma GCC diagnostic ignored "-Wconversion-null"
    #pragma GCC diagnostic ignored "-Wattributes"
    #pragma GCC diagnostic ignored "-Wreturn-type"
    #pragma GCC diagnostic ignored "-Wunused-result"

  #if (!defined(EIGEN_PERMANENTLY_DISABLE_STUPID_WARNINGS)) &&  (__GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ >= 6))
    #pragma GCC diagnostic push
  #endif
  // g++ warns about local variables shadowing member functions, which is too strict
  #pragma GCC diagnostic ignored "-Wshadow"
  #if __GNUC__ == 4 && __GNUC_MINOR__ < 8
    // Until g++-4.7 there are warnings when comparing unsigned int vs 0, even in templated functions:
    #pragma GCC diagnostic ignored "-Wtype-limits"
  #endif
  #if __GNUC__>=6
    #pragma GCC diagnostic ignored "-Wignored-attributes"
  #endif
  #if __GNUC__==7
    // See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89325
    #pragma GCC diagnostic ignored "-Wattributes"
  #endif

3.mkdir build
	cd build
	cmake .. -DCMAKE_INSTALL_PREFIX=../ -DINCLUDE_INSTALL_DIR=../include #设置isntall到eigen-3.4.0/include
	make
	make install

4.使用时在CMakeLists.txt中添加
	INCLUDE_DIRECTORIES(
	"/home/jiatonglee/modules/eigen-3.4.0/include"
	)
