build ffmpeg with eclipse cdt on mac

栏目：综合技术时间：2016-06-02 08:55:16

This FFmpeg version is 2.8

the latest version `make` error , the stable release has no error

eprecated here
void av_picture_copy(AVPicture *dst, const AVPicture *src,
     ^
ffplay.c:3761:24: error: token is not a valid binary operator in a preprocessor subexpression
if CONFIG_AVDEVICE    avdevice_register_all();

/bin/sh: _: command not found

If so I found the problem is that OSX does not pass the PATH variable to applications started through the GUI. So to get around this one should start eclipse from the terminal. This worked when I had the problem.

Installing GDB on OS X Mavericks

Launching "ffplay_g" has encountered a problem
Error with command: gdb --version

Homebrew formula of GDB with patch for OS X Yosemite

brew install https://gist.githubusercontent.com/ymyzk/10ad2b74af9235eddb2c/raw/9d0b9734ea01f9753a5f54dd221acd99ee7e53e8/gdb.rb

Eclipse GDB debugger support

Can’t find the tool settings in Eclipse CDT

I switched C/C++ Build->Builder Settings->Builder type to External Builder, if builder type is disable, do restore defaults, and closed the properties window. When reopening properties the C/C++ Build->Settings->Tool Settings Tab was available.

Error: `unresolved inclusion: <SDL.h>`

Fix: Properties -> C/C++ General -> Paths and Symbols ->includes -> GUN C++ (and GUN C) -> add /usr/local/include/SDL

ffmpeg not support SDL2 now

I am not sure this section is correct, because I not click “run to next” in eclipse. After I do the following step, there are still “No Source Available”, But once I click “next”, everything is well ��

No Source Available
The problem was that I was using the Release version of SDL instead of the Debug version! (I had ‘libsdl’ from MacPorts whereas I should have had ‘libsdl-devel’.)

Building SDL in debug mode on Linux

./configure --enable-debug or CFLAGS='-O0 -g' ./configure

Error:./include/SDL_syswm.h:58:10: fatal error: 'X11/Xlib.h' file not found

Fix:export CPPFLAGS=-I/opt/X11/include

Error:error: unknown type name 'CGDirectPaletteRef'
Fix: 这个SDL的编译毛病居然是由最新的OS X 10.9致使的，参见SDL开发版本库里的1次提交。这是1个月前的1个修复，看来还没有打包到稳定版本中，我就自己依照这次提交来修改代码吧。改以后make通过了. Ref

Error: error: conflicting types for '_XData32'
Fix:
This patch is no correct,

Following patch is right
