qbs avr编译

Question

我尝试用qbs构建简单的项目。

import qbs
Project {
    name: "simple"
    Product {
        name: "micro"
        type: "obj"
        Group {
            name: "sources"
            files: ["main.c", "*.h", "*.S"]
            fileTags: ['c']
        }
        Rule {
            inputs: ["c"]
            Artifact {
                fileTags: ['obj']
                filePath: input.fileName + '.o'
            }
            prepare: {
                var args = [];
                args.push("-g")
                args.push("-Os")
                args.push("-w")
                args.push("-fno-exceptions")
                args.push("-ffunction-sections")
                args.push("-fdata-sections")
                args.push("-MMD")
                args.push("-mmcu=atmega328p")
                args.push("-DF_CPU=16000000L")
                args.push("-DARDUINO=152")
                args.push("-IC:/Programs/arduino/hardware/arduino/avr/cores/arduino")
                args.push("-IC:/Programs/arduino/hardware/arduino/avr/variants/standard")
                args.push("-c")
                args.push(input.fileName)
                args.push("-o")
                args.push(input.fileName + ".o")
                var compilerPath = "C:/Programs/arduino/hardware/tools/avr/bin/avr-g++.exe"
                var cmd = new Command(compilerPath, args);
                cmd.description = 'compiling ' + input.fileName;
                cmd.highlight = 'compiler';
                cmd.silent = false;
                console.error(input.baseDir + '/' + input.fileName);
                return cmd;
            }
        }
    }
}

我会犯错误

compiling main.c
C:/Programs/arduino/hardware/tools/avr/bin/avr-g++.exe -g -Os -w -fno-exceptions -ffunction-sections -fdata-sections -MMD "-mmcu=atmega328p" "-DF_CPU=16000000L" "-DARDUINO=152" -IC:/Programs/arduino/hardware/arduino/avr/cores/arduino -IC:/Programs/arduino/hardware/arduino/avr/variants/standard -c main.c -o main.c.o

我做错什么了？

文件main.c存在于项目和目录中。

如果从命令提示符启动此命令，则不会出现错误。

简而言之，您需要在input.filePath之后传递-c和-o，而不是input.fileName。不能保证调用的命令的工作目录是源目录的工作目录。

您可以设置workingDirectory对象的命令，但通常不建议这样做，因为除非绝对必要，否则命令应该独立于工作目录。

此外，您似乎在重复cpp模块的功能。相反，您的项目应该如下所示：

import qbs
Project {
    name: "simple"
    Product {
        Depends { name: "cpp" }
        name: "micro"
        type: "obj"
        Group {
            name: "sources"
            files: ["main.c", "*.h", "*.S"]
            fileTags: ['c']
        }
        cpp.debugInformation: true // passes -g
        cpp.optimization: "small" // passes -Os
        cpp.warningLevel: "none" // passes -w
        cpp.enableExceptions: false // passes -fno-exceptions
        cpp.commonCompilerFlags: [
            "-ffunction-sections",
            "-fdata-sections",
            "-MMD",
            "-mmcu=atmega328p"
        ]
        cpp.defines: [
            "F_CPU=16000000L",
            "ARDUINO=152"
        ]
        cpp.includePaths: [
            "C:/Programs/arduino/hardware/arduino/avr/cores/arduino",
            "C:/Programs/arduino/hardware/arduino/avr/variants/standard
        ]
        cpp.toolchainInstallPath: "C:/Programs/arduino/hardware/tools/avr/bin"
        cpp.cxxCompilerName: "avr-g++.exe"
    }
}

这是工作args.push("-c") args.push(input.filePath) at you args.push(input.fileName) args.push("-o") args.push(output.filePath)at you args.push(input.fileName)
