Error when making source code on Ubuntu 16.04 #1542

Closed jiayilee97 closed 4 years ago

jiayilee97 commented 4 years ago

i followed these instructions (for linux x86): https://github.com/Tencent/ncnn/wiki/how-to-build

when i tried to build the NCNN using sudo make -j4, i got these errors

The errors are very similar to this: /ncnn/tools/quantize/ncnn2table.cpp:820:26: error: passing ‘const cv::CommandLineParser’ as ‘this’ argument discards qualifiers [-fpermissive]

im using g++-5, gcc5 and opencv 2.4

fixed in https://github.com/Tencent/ncnn/commit/c089ddb3c235033f8da52b5d22639df5b0ff0824

please update the ncnn git code and try again :)

Thanks for the quick reply. There are still errors after running your updated git code.

Here are the screenshots of the error: Screenshot 1 image Screenshot 2 image

hmmm, the opencv api compatibility issue is not so easy to fix

For now, you can comment the quantize directory if you aren't eager to use the quantization tools.

I have the same issue. Have you solved the problem？

helloworld77 commented 4 years ago

The default opencv version of Ubuntu 16.04 is too old, using opencv 3.+ could solve the problem. download and compile 3.x+ version of opencv, then setting the env like this: export PATH=xxx/opencv-3.xx/bin:$PATH then... cd build; cmake ../; make -j10 That works for me

重装一下opencv3就好了，感谢
