make error: (long) unsigned int #31

Open JHPHELAN opened 1 year ago

JHPHELAN commented 1 year ago

upon make there are MULTIPLE errors of the form:

In member function ‘int ydlidar::core::base::Thread::join(long unsigned int)’: /home/ubuntu/YDLidar-SDK/./core/base/thread.h:118:18: warning: format ‘%X’ expects argument of type ‘unsigned int’, but argument 2 has type ‘_size_t’ {aka ‘long unsigned int’} [-Wformat=] 118 printf("0x%X thread has been canceled\n", this->_handle); ~^ ~~~~~
unsigned int _size_t {aka long unsigned int}
%lX

Despite this, the make seems to complete ok and the following sudo make install completes ok.

JHPHELAN commented 1 year ago

@mjlee111 @ghdic I found that, although there are unsigned int errors in 'make', it didn't fail. Also 'sudo make install' installs ok.

Looking at the source code, it seems that I have to fix the error directly. Am I the only one like that?

same errors on my side

JHPHELAN commented 5 months ago

Having upgraded to Ubuntu 22.04 and ROS2 Humble have re-attempted install and get the same "long unsigned int" warnings, but does not crash. Would be fantastic if a better coder that I (a very low bar indeed) would update the code to eliminate these warnings before they become errors with the next upgrade.
