At first thank you very much
I have installed some of the opencv libraries with the command: sudo apt-get libopencv-dev.
Then I can find them in / usr / lib / arm-linux-gnueabihf Directory,such as : libopencv_ Video. a libopencv_ Video. so libopencv_Video.so. 3.2 libopencv_Video. so. 3.2.0
Libopencv_ Videostab Libopencv_ Viz Libopencv_ Ximgproc Libopencv_ Xobjdetect Libopencv_Xphoto Libopencv_Core etc (about 165 files)
Then I used this header file(RaspiOpencv.pas) to prog:
RaspiOpencv
*********************************************************************
* Modified to use Raspberry Pi with Ver3.3. for evaluation purpose.*
* Functions were changed to suit RaspberryPi and FPC Lazarus. *
* Add function cvLoadImageM etc. *
* Replaced Bitmap2IplImage and iplImage2Bitmap. *

The compilation can pass, but there is an error in running. The prompt message is:
Project Project1 raised exception class 'External:SIGTRAP'. In file '../sysdeps/unix/sysv/linux/raise.c' at line 50
File not found
The file '/build/glibc-FUvrFr/glibc-2.28/sysdeps/unix/sysv/linux/raise.c" was not found.
Do you want to locate it yourself?
I did not find this file(raise.c) in the download files (library and source code). How can I do it?
Thank you again
