CMake 各种报错报警

  • integer_sequence’ is not a member of ‘std’

编译工程时报错 integer_sequence’ is not a member of ‘std’
CMake中添加 set(CMAKE_CXX_FLAGS "-std=c++14")

  • CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required): Compatibility with CMake < 2.8.12 will be removed from a future version of CMake

我升级CMake后出现的报警，虽然不影响，但是一旦工程多了以后，这个报警会很烦人。只需要修改cmake_minimum_required (VERSION 3.19.0)

但是有时CMakeLists太多了，不可能一一去修改，使用sed命令集体修改：

sed -i "s/2.8.3/3.19/g" `grep 2.8.3 -rl . --include="*.txt" `

这个命令不要滥用，否则可能更改过多
  • 涉及PCL的一个警告
CMake Warning (dev) at /usr/local/share/cmake-3.17/Modules/FindPackageHandleStandardArgs.cmake:272 (message):
  The package name passed to `find_package_handle_standard_args` (PCL_KDTREE)
  does not match the name of the calling package (PCL).  This can lead to
  problems in calling code that expects `find_package` result variables
  (e.g., `_FOUND`) to follow a certain pattern.

在find_package(PCL REQUIRED)之前加上

if(NOT DEFINED CMAKE_SUPPRESS_DEVELOPER_WARNINGS)
    set(CMAKE_SUPPRESS_DEVELOPER_WARNINGS 1 CACHE INTERNAL "No dev warnings")
endif()
  • No rule to make target

有时明明写好了，但编译会出现报错，看上去是CMakeLists中没有编译规则

make[2]: *** No rule to make target 'package/CMakeFiles/test_bin.dir/build'。 停止。
CMakeFiles/Makefile2:3192: recipe for target 'package/CMakeFiles/test_bin.dir/all' failed
make[1]: *** [package/CMakeFiles/test_bin.dir/all] Error 2
Makefile:138: recipe for target 'all' failed
make: *** [all] Error 2
Invoking "make -j4 -l4" failed

此时再重新编译仍然报错，只要把CMakeLists改一下，再编译就通过了
