New error here with the new package:

How did you fix it? Did you manage to compile with cuda?

acxz commented on 2019-11-21 05:10

Thx for letting me know, I have fixed it. Note installing with CUDA is still troublesome.

@dferio good catch! I tried adding in the flag, however another issue popped up. I get undefined references relating to opencv functions. Do I need to recompile opencv with gcc8 (using that flag) as well? I can't expect users to have opencv compiled a specific way. Did you encounter this issue?

We can also make an issue on the github, the developers are very friendly. I am quite busy these days so sadly I will not be able to spend more time on this issue. Do keep me updated on possible solutions tho and I will try to integrate them into the build process asap.

Building fails, I think you should add -DCMAKE_CXX_FLAGS='-D_GLIBCXX_USE_CXX11_ABI=0' to make it compatible with gcc 8 that is required by Cuda.

@vfbsilva I believe you only need to do that if you are using just the Makefile. This package uses darknet's CMakeLists.txt which does properly find opencv.

vfbsilva commented on 2019-06-16 06:50

Opencv was not being properly found. I did a dirty hack I'm not even sure is right:

export PKG_CONFIG_PATH=/usr/lib/pkgconfig sudo cp -p /usr/lib/pkgconfig/opencv4.pc /usr/lib/pkgconfig/opencv.pc

I think I could have modified the makefile but my test did work so I kept it.

acxz commented on 2019-06-15 22:13

Is it possible to do a clean build of a package using yaourt? If not can you manually build the package without using an AUR helper or use one that does allow you to do that like yay?
