Compiling source: COLMAP make failed at 96%

[abai...@gmail.com]

Hello,

I am relatively new to Linux and am seeking some foolproof advice for installing COLMAP on Ubuntu 16.04. I have followed the instructions here:

https://colmap.github.io/install.html#build-from-source

However, It crashes with an error at 96% completion. For trial and error sake, I have started from scratch 3 times now and I still get the same error. The error looks like this:

/usr/include/string.h: In function ‘void* __mempcpy_inline(void*, const void*, size_t)’:
/usr/include/string.h:652:42: error: ‘memcpy’ was not declared in this scope
   return (char *) memcpy (__dest, __src, __n) + __n;
                                          ^

I appreciate any advice in advance!

I resolved adding

 -D_FORCE_INLINES

to line 188 of CMakeLists.txt

resulting in

        set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} -D_FORCE_INLINES -Wno-deprecated-gpu-targets")

Dude!!

I was just trying to insall colmap on my machine, and looked on Google for this exact problem.

Your post, posted 14 minutes before I found it, just saved me, so thanks for sharing, and +1 I guess!

Good colmaping!

[Johannes Schönberger]

Thanks for reporting the fix. It seems like this is a common issue under some combinations of GCC/CUDA. I already added the flag to some of the subfolders, but now also enabled the flag globally for all COLMAP CUDA code with the most recent commit in the dev branch. Let me know if the code compiles now without any manual change on your side. Thanks.

Cheers, Johannes

I confirm that now it compiles.

current dev branch and Ceres 1.14

I can also confirm that it now compiles without any issues using the latest version of the dev branch. Thank you!!

I got this with Cuda 11.7 and Ceres 2.1. Following the instructions precisely, still colmap would not get installed.

Me too, I also got this error.
