嵌入式软件交叉编译： junk at end of line, first unrecognized character 问题解决可有偿

Question

windows上使用arm-none-eabi-gcc 编译器编译.c汇编文件出现以下错误：

CMAKE构建好后，直接make -j20，使用ARM GCC 14.2进行交叉编译一系列.c文件时，Stm_Ip_PBcfg.c出现以上问题不知道如何处理？有些博主说是将.S改为.s，可我这是.c文件不是汇编，不知道怎么处理？
附加信息：
在用cmake进行构建时，使用target_sources链接到执行文件上，构建是成功的。

根据错误提示，可能是源文件中存在非ASCII字符导致编译错误。建议检查源文件中是否存在非ASCII字符，特别是前面的提示中提到"valued 0x7f"和"valued 0x1"的地方，可能是因为这些字符引起的问题。 如果确定源文件中没有非ASCII字符，可以尝试使用文本编辑器将源文件重新保存为UTF-8编码，或者尝试重新编译整个项目以确保没有其他因素导致这种问题。 以下是一个简单的示例代码来将一个文件保存为UTF-8编码：

#include <stdio.h>
int main() {
    // Open the input file
    FILE *inputFile = fopen("input.c", "rb");
    if (inputFile == NULL) {
        perror("Error opening input file");
        return 1;
    }
    // Open the output file
    FILE *outputFile = fopen("output.c", "wb");
    if (outputFile == NULL) {
        perror("Error opening output file");
        fclose(inputFile);
        return 1;
    }
    int c;
    // Read each character from input file and write to output file
    while ((c = fgetc(inputFile)) != EOF) {
        fputc(c, outputFile);
    }
    // Close both files
    fclose(inputFile);
    fclose(outputFile);
    printf("File saved as UTF-8 successfully\n");
    return 0;
}

可以将待转换的源文件保存为input.c，然后运行该程序即可将其保存为UTF-8编码的output.c文件。希望能帮到您解决问题。
