当尝试使用Xcode编译时,我收到以下错误:

这是无害的,还是我应该采取其他措施让Git接受这一变化？
我在 M1 MacBook 上。这是我尝试安装 Homebrew 时的错误：
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Homebrew is not (yet) supported on ARM processors!
Rerun the Homebrew installer under Rosetta 2.
If you really know what you are doing and are prepared for a very broken experience you can use another installation option for installing on ARM:
https://docs.brew.sh/Installation
那么我如何“在 Rosetta 2 下重新运行 Homebrew 安装程序”？
我试图在Ubuntu 9.10(gcc 4.4.1)中编译我的C程序.
我收到此错误:
Rect.cpp:344: error: ‘memset’ was not declared in this scope
但问题是我已经包含在我的cpp文件中:
#include <stdio.h>
#include <stdlib.h>
同样的程序在Ubuntu 8.04(gcc 4.2.4)下编译得很好.
请告诉我我错过了什么.
不久前我将Xcode更新到版本4.这个新版本花了很多时间来索引项目(它非常大).这就是我想禁用索引的原因.搜索Xcode帮助和互联网没有结果.
先感谢您!
当我使用Xcode 4构建我的应用程序时,它总是显示以下错误消息:

检查/Volumes/WORK/Works/iMusicBox/Images/list_cell.png pngcrush中的alphas时检测到libpng错误:图像数据不够
但Xcode 3.2没关系 - 为什么？
我正在阅读McConell的Code Complete,他讨论了使用布尔变量来记录代码.例如,而不是:
if((elementIndex < 0) || (MAX_ELEMENTS < elementIndex) ||
(elementIndex == lastElementIndex)){
...
}
他建议:
finished = ((elementIndex < 0) || (MAX_ELEMENTS < elementIndex));
repeatedEntry = (elementIndex == lastElementIndex);
if(finished || repeatedEntry){
...
}
这让我感到逻辑,良好的实践和非常自我记录.但是,我对于经常使用这种技术犹豫不决,因为我几乎从未遇到过这种技术; 也许只是因为稀有而令人困惑.然而,我的经验还不是很大,所以我有兴趣听听程序员对这种技术的看法,我很想知道是否有人经常使用这种技术或者在阅读代码时经常看到它.这是一个值得采用的约定/风格/技术吗？其他程序员会理解并欣赏它,还是认为它很奇怪？
我在Xcode 4中运行一个"旧的"Xcode 3项目,代码感觉不适用于我自己的类.我试过以下:
没有运气.
有时代码意义有效但主要是我得到"没有完成".
我尝试了这个代码,但它无法正常工作
#!/bin/sh
#Find the Process ID for syncapp running instance
PID=`ps -ef | grep syncapp 'awk {print $2}'`
if [[ -z "$PID" ]] then
Kill -9 PID
fi
它在awk附近显示错误.
请给我任何建议.
我使用最新的Apple M1芯片处理器。而且我在应用程序安装时不断收到错误消息。
说。，
brew install openjdk@11
Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)!
Please create a new installation in /opt/homebrew using one of the
"Alternative Installs" from:
https://docs.brew.sh/Installation
You can migrate your previously installed formula list with:
brew bundle dump
需要帮助以了解要遵循的确切步骤。
