make: nothing to be done for 'all'

Post by **TELunus** » Sat Feb 10, 2018 10:44 pm

Hello

I'm having an issue trying to build a simple hello world program. The code is just main.cpp:

#include <iostream>

int main(int argc, char **argv)
{
    std::cout << "Hello World" << std::endl;
    return 0;
}

However when I do a build and run the Build tab just says

Code: Select all

C:\Windows\system32\cmd.exe /C C:/MinGW/bin/mingw32-make.exe -j12 SHELL=cmd.exe -e -f  Makefile
"----------Building project:[ hello - Debug ]----------"
mingw32-make.exe[1]: Entering directory 'C:/Users/TELun/Documents/Sandbox2/hello'
mingw32-make.exe[1]: Nothing to be done for 'all'.
mingw32-make.exe[1]: Leaving directory 'C:/Users/TELun/Documents/Sandbox2/hello'
====0 errors, 0 warnings====

Which would be expected if my program had just been built before and no changes had happened since. However that should mean that the code I have as written should be running. Unfortunately the command prompt window that shows up just says

Code: Select all

Press any key to continue.

No mention of "hello world"

After hitting enter on the command prompt the CodeLite's Output tab shows:

Code: Select all

Current working directory: C:\Users\TELun\Documents\Sandbox2\hello\Debug
Running program: le_exec.exe C:\Users\TELun\Documents\Sandbox2\cmake-build-Debug\output\hello
Program exited with return code: 0

So make is telling me there's nothing to be done even though it's not keeping up to date with my code. That sounds like there's a problem with the makefile. The file being called in the make command is Sandbox2\Makefile:

Code: Select all

.PHONY: clean All

All:
	@echo "----------Building project:[ hello - Debug ]----------"
	@cd "hello" && "$(MAKE)" -f  "hello.mk"
clean:
	@echo "----------Cleaning project:[ hello - Debug ]----------"
	@cd "hello" && "$(MAKE)" -f  "hello.mk" clean

This in turn references Sandbox2\hello\hello.mk

Code: Select all

Now I'm not great at reading makefiles, so I'm not really sure how correct that is. All I know is that it's not causing make to issue compiler calls. I also know that CodeLite is supposed to be generating makefiles that cause this project to be built using its builtin generator.

My compiler is clang 4.2.1, which I downloaded an installer for from the LLVM website (i.e. not self compiled)
My operating system is Windown 10
My build system is mingw32-make.exe from MinGW
I've got my makefile generator set to Default, which CodeLite says will make it use its builtin makefile generator.
My codelite version says 10.0.1, which I downloaded an installer for from the CodeLite website (i.e. not self compiled)

Any help getting this hello world will be much appreciated!
