我目前正在使用Mac OS X,现在我需要构建一个.exe文件,以便Go程序可以在Windows上运行.那么问题是如何在MacOS amd64下为Win X86构建可执行文件？或者这样做不可能吗？
我正在使用Emacs for Mac OS X 24.2.一旦emacs被卡住,然后我就杀了这个过程,但当我重新打开它时,下面显示了一些警告:
warning: desktop file appears to be in use by PID 200.
Using it may cause conflicts. Use it anyway? (y or n)
从那时起,每次打开Emacs时都会显示消息,那么我们应该怎么做才能修复它？我真的很生气.顺便说一下,我的操作系统是Mac OS X 10.7.5
Windows 10 x64,ffmpeg:3.1,预构建的dll
绝对的初学者在这里.
我正在尝试一个非常基本的案例来解码视频文件中的帧,但每次尝试时都拼命失败.最终的代码片段如下所示:
#define __STDC_CONSTANT_MACROS
extern "C" {
#include<libavutil/avutil.h>
#include<libavutil/imgutils.h>
#include <libavformat/avformat.h>
#include <libavcodec/avcodec.h>
#include <libswscale/swscale.h>
}
#include <iostream>
int main(int argc, char **argv) {
AVFormatContext* ctx_format = nullptr;
AVCodecContext* ctx_codec = nullptr;
AVCodec* codec = nullptr;
AVFrame* frame = av_frame_alloc();
int stream_idx;
SwsContext* ctx_sws = nullptr;
const char* fin = argv[1];
AVStream *vid_stream = nullptr;
AVPacket* pkt = av_packet_alloc();
av_register_all();
if (int ret = avformat_open_input(&ctx_format, fin, nullptr, nullptr) != 0) {
std::cout << 1 << std::endl;
return …它有点连线,我试图安装octopress,一切都很顺利,但我只是无法使用rake preview.我尝试查看预览时有一些信息:
服务器似乎没问题:

Dear developers making use of FSSM in your projects,
FSSM is essentially dead at this point. Further development …
