Error with c++11 compiler #14

Closed pankhurivanjani closed 2 years ago

pankhurivanjani commented 2 years ago

Hello!

I am trying to run the code, while building tandem I am getting 2 major errors from cuda_coarse_tracker side. I have cuda 11.1, and same cudNN and libtorch version as mentioned in readme.

Could you suggest anything to solve these?

I am using SET(CMAKE_CXX_FLAGS "-std=c++0x") in CMakeLists.txt

Thanks,

Update1: I fixed the cnpy error by cloning the cnpy repo, cmake, make and make install for future reference

C++11 Compiler error still remains

This error was coming in dr_mvsnet too but using SET(CMAKE_CXX_FLAGS "-std=c++0x") in Cmakelists.txt solved the issue but somehow it is not helping for cuda_coarse_tracler

I also tried using set (CMAKE_CXX_STANDARD 11) In CMakeLists.txt but the next error log set comes

I can see this line in the cmakelists of cudacoarser https://github.com/tum-vision/tandem/blob/master/tandem/libdr/cuda_coarse_tracker/CMakeLists.txt#L23 @lkskstlr Did you also had this problem while developing?

pankhurivanjani commented 2 years ago

This was compiler version error, this code gives problem with g++5/gcc5 version.

I got hint from here https://github.com/getkeops/keops/issues/102 and wasable to solve this problem after upgrading to g++7/gcc+7 by increasing the priority as explained here https://stackoverflow.com/questions/7832892/how-to-change-the-default-gcc-compiler-in-ubuntu

I Hope, it helps future users!

I can see this line in the cmakelists of cudacoarser https://github.com/tum-vision/tandem/blob/master/tandem/libdr/cuda_coarse_tracker/CMakeLists.txt#L23 @lkskstlr Did you also had this problem while developing?

I am having this exact error but I am using gcc-7. Any idea on how to solve this?
