怎么在编译的代码中添加构建版本

这个“构建版本”从何而来？



      以下为原文

    Where might this "build version" come from ?

如果有日期和时间符号可用，那就太好了。我也不记得了，有人知道吗？${De}}似乎是nul.gP



      以下为原文

   


It would be nice if there were date and time symbols available.  I don't recall either, does anyone know for sure?  ${DATE} seems to be null.

您可以在源代码（这里是XC16）中执行，但这当然不是一个“构建”版本，它必须有一些“原点”。你不会真的想为每个编译器运行（我假设）增加你的构建号。&编辑：忘了说：如果你不指定你想“显示”或稍后检索它，你的构建版本是相当无用的。



      以下为原文

    You could do that within the source code (here xc16),
 
#ifdef __XC16__
   dbgPuts("XC16-");
   dbgPutDec(__XC16_VERSION__);
   dbgPutc(':');
 #else
   dbgPuts("C30: ");
 #endif

  dbgPuts("Compiled ");          // output Build Date and Time
  dbgPuts(__DATE__);
  dbgPutc(',');
  dbgPuts(__TIME__);
 

 
but that's of course not a "Build" version, which must have some "origin".  You would not really want to increment your build number just for each compiler run (I assume).
 

在G.CMD文件中使用Git作为预构建选项。



      以下为原文

    I use this with git in a .cmd file as a prebuild option.
 

git rev-list --full-history --all --abbrev-commit | wc -l | "D:Program Files (x86)GnuWin32binsed.exe" -e "s/^ *//" >>AppConfiguration.h
echo|set /p="#define GIT_HASH " >>AppConfiguration.h
git rev-list --full-history --all --abbrev-commit | head -1 >>AppConfiguration.h

我使用一个简单的Windows控制台应用程序，它运行为一个预构建步骤：-它创建一个文件（BuffdNo..h作为默认值，但接受一个文件名作为参数），其中生成号既定义为整数又是String宏，每次运行时都增加它。不管怎样，你需要它。邮政1000！[/OT ]



      以下为原文

    I use a simple Windows console app which runs as a pre-build step:-
// BuildNumber.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "stdio.h"
#include "string.h"
#include "ctype.h"
#include "stdlib.h"

int main(int argc, char* argv[])
{
    char filename[1024];
    strcpy(filename,"buildnumber.h");
    char linebuf[1024];
    int nBuild=1;
    if (argc>1)
    {
        char *cmd=argv[1];
        strncpy(filename,cmd,1023);
    }
    printf("BuildNumber 1.0n");
    printf("© S. Gregory 2016n");
    FILE *fp=fopen(filename,"r+");
    if (fp)
    {
        memset(linebuf,0,sizeof(linebuf));
        int ctr=0;
        while(fgets(linebuf,1023,fp))
        {
            char *cctr;
            for(cctr=linebuf;*cctr;cctr++)
                *cctr=tolower(*cctr);
            char *pctr=linebuf;
            while((*pctr)&&(isspace(*pctr))) pctr++;
            if (strncmp(pctr,"#define buildnumber",19)==0)
            {
                nBuild=atol(pctr+19)+1;
                fclose(fp);
                fp=fopen(filename,"w");
                if (fp)
                {
                    fprintf(fp,"/* Generated by BuildNumber Version 1.0 */rnrn");
                    fprintf(fp,"#ifndef BUILD_NUMBER_H_rn");
                    fprintf(fp,"#define BUILD_NUMBER_H_rnrn");
                    fprintf(fp,"#define BUILDNUMBER %drn",nBuild);
                    fprintf(fp,"#define BUILDNUMBER_STR "%04d"rn",nBuild);
                    fprintf(fp,"#endif /* BUILD_NUMBER_H_ */rn");
                    printf("Build %dn",nBuild);
                    fclose(fp);
                    return 0;
                }
                else
                {
                    printf("File Open Errorrn");
                }
                return -1;
            }
        }
        printf("%s not validrn",filename);
        fclose(fp);
        return -2;
    }
    else
    {
        fp=fopen(filename,"w");
        if (fp)
        {
            fprintf(fp,"/* Generated by BuildNumber Version 1.0 */rnrn");
            fprintf(fp,"#ifndef BUILD_NUMBER_H_rn");
            fprintf(fp,"#define BUILD_NUMBER_H_rnrn");
            fprintf(fp,"#define BUILDNUMBER %drn",nBuild);
            fprintf(fp,"#define BUILDNUMBER_STR "%04d"rn",nBuild);
            fprintf(fp,"#endif /* BUILD_NUMBER_H_ */rn");
        }
        else
        {
            printf("File Open Errorrn");
            return -1;
        }
        fclose(fp);
        printf("Build %dn",nBuild);
        return 0;
    }
    return -3;
}
It creates a file (buildnumber.h as default, but accepts a filename as a parameter), in which the build number is defined both as integer and string macros, and is incremented each time it is run.
You can then include buildnumber.h wherever you need it.

大家好，首先感谢大家的回答。实际上，我想做的是保存在UC内存中的构建版本（有效地增加每个代码的构建），以便在程序运行时使用它（通过UART发送）。我发现了关于这个主题的有趣文章（link）。它可能是第一个输入，但是我如何修改这个代码来保存UC内存中的值呢？谢谢你的帮助。问候，朱利安。



      以下为原文

    Hi everyone,
 
First, thanks to all for your answers. Actually, what I want to do is to save the build version (effectively a number, which will be incremented for each build of the code) in the uC memory to be able to use it when the program is running (send it over UART). 
I found this interesting article regarding this topic (link). It could be a first input, but how could I modify this code to save the value in the uC's memory?
 
Thank you in advance for your help.
 
Regards,
 
 
Julien

几年前我在C中也做了同样的事情，正义命令行版本看起来不错。



      以下为原文

    I did the same thing in C some many years ago; also the just-command-line version looks nice

I（在XC32项目中）将预定义的α-DATEYSY显示为字符串，而对于我使用的版本，将其定义为“2.30”或任何内容。复制粘贴代码；我不假装理解C的预处理器！没有做任何自动递增的构建号（但是）。这两个值（字符串，在这种情况下）被保存在微控制器程序存储器中，所以可以像任何其他常量一样使用——在这种情况下，我在电源UP.DOM上显示一个漂亮的小OLED。



      以下为原文

    I (in an XC32 project) display the predefined  __DATE__ as a string, and for version I use
 
#define versionmaj 2
#define versionmin 30

// from https://gcc.gnu.org/onlinedocs/cpp/Stringification.html
#define xstr(s) str(s)
#define str(s) #s     
#define version xstr(versionmaj)"."xstr(versionmin)

 
which defines version as "2.30" or whatever.  Copy-pasted code; I don't pretend to understand C's pre-processor!  Not done any auto-incrementing build numbers (yet).
 
Both values (strings, in this case) are saved in the microcontrollers program memory so can be used like any other constant - in this case I show them on a nice little OLED on power up.

对于PIC18设备，您可以在项目构建上插入信息，使其出现在Flash中的已知位置，并且可以在HEX文件中看到：这是因为内存被组织成16位字。对于PIC16F设备中的14位内存字来说，它不太好用。



      以下为原文

    For PIC18 devices, you can insert information on the project build such that it appears at a known location in flash and it can be seen in the hex file:
 
const char PROJECT[] @ 0x100 = "SCRPCB1";
//__attribute__((address(0x100)))    const char PROJECT[] = "SCRPCB1";
__attribute__((address(0x110)))    const char VERSION[] = "1.40";
__attribute__((address(0x120)))    const char DATE[] = "10/26/2016";
 
:0600000000F00BEF00F020 ----       
:10000800F3CF04F096EC03F004C0F3FF110021EFE6 ----               !
:0200180007F0EF ----   
:08010000534352504342310009 ---- SCRPCB1
:06011000312E3430000026 ---- 1.40  
:0C01200031302F32362F323031360000E3 ---- 10/26/2016 
 
This works because the memory is organized as 16 bit words. It doesn't work so well for 14 bit memory words in PIC16F devices.

关于这个主题的其他线程：AutoDelpValueAutoDelphi版本增加了一个关于添加Git提交号的线程，但是我再也找不到它了。

There was even a thread about adding Git commit numbers, but I can't find it anymore.

这与上面的Jim Nickersons邮局有什么不同吗？

Is this different to Jim Nickersons post above?
