Example camfilter fails

Example camfilter fails

Opened this issue 5 years ago · 8 comments

I have a self-built LLVM/Clang 6.0.1 and building with examples fails at camfilter with

I also have custom built opencv 4.0.1

Answer 2 · 2019-03-17T12:48:10.000Z

fixed it by replacing said lines with this:

    cv::putText(*Out, fps_message.str().c_str(), cv::Point(30,30),
                cv::FONT_HERSHEY_COMPLEX_SMALL, 0.8,
                cv::Scalar(200,200,250), 1, cv::LineTypes::LINE_AA);

but now I get the following errors:

added .txt file endings because githubs upload filter
camfilter-f88ddd.cpp.txt
camfilter-f88ddd.sh.txt

Answer 4 · 2019-03-18T07:33:32.000Z

looks like I forgot to set the LLVM_EXPORT_SYMBOLS_FOR_PLUGINS cmake variable when building llvm/clang... might be related to that.
I'll get back on that once building has finished.

now I get:

Answer 6 · 2019-03-19T09:17:45.000Z

I had the same error, i fixed it by adding this two header (in camfilter.cpp):

#include <opencv2/imgproc/imgproc_c.h>  
#include <opencv2/core/types_c.h>

imgproc_c.h contains definition for CV_AA
types_c.h contains definition of cvPoint (It was not defined when i tried to build the example)

I didn't change the line like you did by the way.

Answer 7 · 2019-03-19T15:40:54.000Z

Good to know, but i prefer the c++ headers.

Still, there is the problem with the undefined symbol _ZTVN4llvm2cl6parserINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEEE'

Answer 8 · 2019-03-19T17:48:02.000Z

I could resolve the symbol by adding llvm_config(EasyJitPass support) to pass/CMakeLists.txt.

Now I get this:
