error: Ordered comparison of pointer with integer zero ('char*' and 'int') when compiling in traffic.cpp

[Arsivnet]

When i try the command in the INSTALL manual: sudo make install PREFIX=/usr/local

I get the error in error_1.png "böyle bir dosya ya da dizin yok" means "no such file or directory"

When i try sudo make I get the error in error_2.png

Which is weird because i thought that "NULL" and normal "0" are interchangable in C. Could it be because of compiler versions?

I also faced this recently. You're right, it's probably due to compiler versions. Have a look at this - https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87699 This did not happen before GCC 11+, where this has now been implemented.

Were you able to compile it ? @hrishikeshathalye @Arsivnet

@Dhyey-Thummar I changed the code a bit to account for the errors, but now when i try to compile i get this error. Anyone know what -lITG flag is all about in the makefile in ITGManager?

Edit: fixed formation
