1、編譯
1、下載代碼
2、複製到kms-omni-build# 目錄下
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、編譯錯誤及解決辦法
問題 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.
解決辦法：不用編譯tests 模塊， 在CMakefile.txt中註釋掉
../kms-omni-build/kms-pointerdetector# vi CMakeLists.txt
add_subdirectory(src)
#add_subdirectory(tests)
問題 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 ();
解決辦法： session = soup_session_sync_new (); 改爲 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+");
問題 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]) -
^~~~
解決辦法：加#include<math.h>
問題 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);
解決辦法：加頭文件#include<opencv2/imgcodecs/imgcodecs_c.h>
