aobo@aobo-tp:/usr/include/ni$
Now let's look at the header and link files of the openni installation:
The following two commands do not detect openni's header file path.
aobo@aobo-tp:/usr/include/ni$ pkg-config --cflags openni
Package openni was not found in the pkg-config search path.
Perhaps you should add the directory containing `openni.pc'
to the PKG_CONFIG_PATH environment variable
No package 'openni' found
aobo@aobo-tp:/usr/include/ni$ pkg-config --cflags ni
Package ni was not found in the pkg-config search path.
Perhaps you should add the directory containing `ni.pc'
to the PKG_CONFIG_PATH environment variable
No package 'ni' found
aobo@aobo-tp:/usr/include/ni$ Correct commands:
aobo@aobo-tp:~$ pkg-config --cflags libopenni
-I/usr/include/ni
aobo@aobo-tp:~$ pkg-config --libs libopenni
-lOpenNI
aobo@aobo-tp:~$ My current project is in the QT. The solution is:
In the. pro file, add openni header file path and link file path.
INCLUDEPATH += /usr/include/ni
LIBS += -L/usr/lib -lOpenNIMore wonderful blogs, please visit: http://www.aobosir.com/
