Building a c program with gradle

Question

I am new to creating a c / cpp plugin in gradle. This is the project structure.

.
|-- build.gradle
`-- src
    `-- main
        `-- c
            `-- hello.c

Content hello.c

#include <stdio.h>

int main(int argc, char** argv){
    printf("Hello World!\n");
    return 0;
}

Build.gradle content

apply plugin: 'c'

executables {
    main {
    }
}

When I run: $ gradle mE, I get the following error

FAILURE: Build failed with an exception.

* Where:
Build file '/home/sujith/Downloads/cpp-examples-master/gradle-c-plugin/03-executable/build.gradle' line: 3

* What went wrong:
A problem occurred evaluating root project '03-executable'.
> Could not find method executables() for arguments [build_aaxd7x5nukew1jgziyan9q177$_run_closure1@57552dfc] on root project '03-executable'.

Am I missing something? Any help is appreciated. Thanks you

Answer 1

I ran into the same problem when the use is executables { ... }not working and it produces the same error as you mentioned. It was probably used in an older version of gradle.

I referred to gradle docs for creating my own binaries.

build.gradle:

apply plugin: 'c'

model {
  components {
    main(NativeExecutableSpec) {}
  }
}

.

gradle tasks, , .

gradle build build/binaries/mainExecutable/main.

, , , , C.

EDIT. , . , build.gradle. clincher , executables {...}, libraries {...} .., , , , .
