kuento 学习-kms-pointerdetector 编译-运行-调试

1、编译

1、下载代码
2、复制到kms-omni-build# 目录下
3、修改kms-omni-build# vi CMakeLists.txt

../kms-omni-build# vi CMakeLists.txt

...

dd_subdirectory(kms-pointerdetector)

list(INSERT CMAKE_MODULE_PATH 0 "${CMAKE_CURRENT_BINARY_DIR}/kms-pointerdetector/src/server")

list(INSERT CMAKE_PREFIX_PATH 0 "${CMAKE_CURRENT_BINARY_DIR}/kms-pointerdetector")
list(INSERT CMAKE_PREFIX_PATH 0 "${CMAKE_CURRENT_SOURCE_DIR}/kms-pointerdetector")
set(KMSFILTERS_BINARY_DIR_PREFIX "${CMAKE_CURRENT_BINARY_DIR}" CACHE PATH "Path prefix used to look for binary files" FORCE)
set(KMSFILTERS_SOURCE_DIR_PREFIX "${CMAKE_CURRENT_SOURCE_DIR}" CACHE PATH "Path prefix used to look for source files" FORCE)

set(KURENTO_MODULES_DIR "${KURENTO_MODULES_DIR};${CMAKE_CURRENT_BINARY_DIR}/kms-pointerdetector/src/server/kmd" CACHE PATH "Directory where kurento modules descriptors can be found" FF
ORCE)

...

2、编译错误及解决办法

问题 1、

Make Error at kms-pointerdetector/tests/check/CMakeLists.txt:11 (target_link_libraries):
  Attempt to add link library "glib-2.0" to target "kmstestutils" which is
  not built in this directory.

解决办法：不用编译tests 模块， 在CMakefile.txt中注释掉

../kms-omni-build/kms-pointerdetector# vi CMakeLists.txt 

add_subdirectory(src)
#add_subdirectory(tests)

问题 2、

/home/sandra/kms/kms-omni-build/kms-pointerdetector/src/gst-plugins/pointerdetector/kmspointerdetector.c:163:3: error: ‘soup_session_sync_new’ is deprecated: Use 'soup_session_new' in]
   session = soup_session_sync_new ();

解决办法： session = soup_session_sync_new (); 改为 soup_session_new ()；

  SoupSession *session;
  SoupMessage *msg;
  FILE *dst;

  session = soup_session_sync_new ();  
  msg = soup_message_new ("GET", url);
  soup_session_send_message (session, msg);

  dst = fopen (file_name, "w+");

  SoupSession *session;
  SoupMessage *msg;
  FILE *dst;

  session = soup_session_new ();//soup_session_sync_new ();  //wanli
  msg = soup_message_new ("GET", url);
  soup_session_send_message (session, msg);

  dst = fopen (file_name, "w+");

问题 4、

/home/sandra/kms/kms-omni-build/kms-pointerdetector/src/gst-plugins/pointerdetector/kmspointerdetector.c:890:9: error: implicit declaration of function ‘sqrt’ [-Werror=implicit-function-declaration]
         sqrt (((abs (pointerdetector->priv->finalPointerPosition.x - p[0]) -
         ^~~~

解决办法：加#include<math.h>

问题 5、

/home/sandra/kms/kms-omni-build/kms-pointerdetector/src/gst-plugins/pointerdetector/kmspointerdetector.c:188:9: error: implicit declaration of function ‘cvLoadImage’; did you mean ‘cvShowImage’? [-]
   aux = cvLoadImage (uri, CV_LOAD_IMAGE_UNCHANGED);
         ^~~~~~~~~~~
         cvShowImage
make[2]: Circular kms-core/src/server/core.kmd.json <- kms-core/src/server/core.kmd.json dependency dropped.
/home/sandra/kms/kms-omni-build/kms-pointerdetector/src/gst-plugins/pointerdetector/kmspointerdetector.c:188:27: error: ‘CV_LOAD_IMAGE_UNCHANGED’ undeclared (first use in this function)
   aux = cvLoadImage (uri, CV_LOAD_IMAGE_UNCHANGED);

解决办法：加头文件#include<opencv2/imgcodecs/imgcodecs_c.h>

编译通过，main: Kurento Media Server started
