[gradle-dev] Re: Sample for native cross compilation?

[johnrengelman]

I have no experience using the native tools but I think you can reference the 
GccToolChainCustomisationIntegrationTest class in gradle-core.

In that test they are doing the following:
            model {
                toolChains {
                    ${gcc.id} {
                        addPlatformConfiguration(new ArmArchitecture())
                    }
                }
                platforms {
                    arm {
                        architecture "arm"
                    }
                    i386 {
                        architecture "i386"
                    }
                }
            }

            class ArmArchitecture implements TargetPlatformConfiguration {
                boolean supportsPlatform(Platform element) {
                    return element.getArchitecture().name == "arm"
                }

                List<String> getCppCompilerArgs() {
                    ["-m32", "-DFRENCH"]
                }

                List<String> getCCompilerArgs() {
                    ["-m32", "-DFRENCH"]
                }

                List<String> getObjectiveCCompilerArgs() {
                    []
                }

                List<String> getObjectiveCppCompilerArgs() {
                    []
                }

                List<String> getAssemblerArgs() {
                    []
                }

                List<String> getLinkerArgs() {
                    ["-m32"]
                }

                List<String> getStaticLibraryArchiverArgs() {
                    []
                }
            }


My guess is that you'll want to do something like that.
