if used in project directory: the make command compiler, is also no problem, can produce an executable file,

Using qtcreator compiler will go wrong, what reason be,

CodePudding user response:

Complier add a c + + compiler, you fill in is c

CodePudding user response:

Your compiler should be g + + ah, how do you become a c, not directly modify Makefile to compiler command to change into available, such as: g + +
General corresponding Makefile in the variable $(MAKE)

CodePudding user response:

A newspaper wrong, know cross-compilation environment variable configuration,
Yocto cross-compilation environment, configuration into the Qt Creator, there are two ways:
The first: simple point, at the command line, first souce environment - setup - * * * * *, and then the command line to perform startup Qt
The orders of the Creator;
The second: a little more complicated, it is through the env command to print all the environment variables, and then copy these environment variables to the Qt environment option in the configuration of the Kits,

I see, you are Qt 5.3.2 the Creator of the location of the unknown environment, if not, you can install a slightly higher version of the Creator, is my Qt5.8,

CodePudding user response:

If there is always some compile in qt configuration of the above problems, and don't know how to solve the proposed to qt reinstall, or install the updated version, configure the environment again, it may be faster to solve the problem, because sometimes from already forgot to modify where, always can't normal use, anyway, I be a few times, so get along while, reinstall and reconfigure the normal,,,

Problem solving, it is a question of environment variables,
