double free or corruption (out) about river

Can you point out the specific location of this error? I saw a warning above the error message in the picture that shouldn't appear: "Framebuffer with requested attributes not available, Using available framebuffer...". This warning does not come from our library.

I searched and found that it comes from the visualization library Pangolin. And this problem is also explained in its readme. Hope this helps!

This doesn't seem to make sense. We don't have any problems with our computer at all. What do you think is the problem? 😭

"Hi bro, I had a similar problem once. I solved the problem by modifying the CMakeLists.txt file. Modify lines 10 and 11 as follows:"
Before modification

set(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -march=native")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -march=native")

After modification

set(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE}")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE}")

“嗨兄弟，我曾经遇到过类似的问题。我通过修改CMakeLists.txt文件解决了该问题。修改第10行和第11行如下：” 修改前

set(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -march=native")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -march=native")

修改后

set(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE}")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE}")

Bro, you're really talented!"

Awesome, problem solved 😃 .

The -march=native option in GCC compiler is used to automatically set compilation flags based on the features supported by your CPU. If you're using an Intel or AMD CPU and a GCC version 4.2.3 or higher, it's recommended to use -march=native.

This option adjusts the compilation settings according to your CPU architecture and instruction set extensions, optimizing the generated machine code. It selects the best instruction set based on your CPU's capabilities, which can improve program performance.

In summary, -march=native is a convenient option that automatically optimizes compilation results based on your hardware environment .
