生活随笔收集整理的這篇文章主要介紹了 cygwin 编译 android vlc,Cygwin 编译 VLC 问题小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

Cygwin 編譯 VLC

遇到了這么多問題，不過還好最后編譯過去了。

問題

1：

gcc -mno-cygwin -Wsign-compare

-Wall -mms-bitfields -pipe -o libaccess_output_dummy_plugin.dll

-g

-shared -u _vlc_entry__0_8_6?-L/usr/win32/lib

libaccess_output_dummy_plugin.a -L/usr/local/lib

if gcc -mno-cygwin -DHAVE_CONFIG_H -I. -I.

-I../..?-I/usr/win32/include

-I/usr/win32/include/ebm

l -D_OFF_T_ -D_off_t=long -DSYS_MINGW32 -I../../include

`top_builddir="../.." ../../vlc-config --c

flags plugin access_output_file` -Wsign-compare

-Wall?-mms-bitfields -pipe -MT

libaccess_output_f

ile_plugin_a-file.o -MD -MP -MF

".deps/libaccess_output_file_plugin_a-file.Tpo" -c -o

libaccess_ou

tput_file_plugin_a-file.o `test -f 'file.c' || echo './'`file.c;

then mv -f ".deps/libaccess_output_file_plugin_a-file.Tpo"

".deps/libaccess_output_file_pl

ugin_a-file.Po"; else rm -f

".deps/libaccess_output_file_plugin_a-file.Tpo"; exit 1; fi

In file included from file.c:30:

/usr/lib/gcc/i686-pc-mingw32/3.4.4/../../../../i686-pc-mingw32/include/sys/stat.h:113:

解決辦法:

/usr/i686-pc-mingw32/include/sys目錄下

在stat.h的文件開始處添加

#ifndef _OFF_T DEFINED

typedef long off_t;

#define _OFF_T DEFINED

#endif

解決方法：

./configure 后會生成 vlc-config

文件

修改 vlc-config 文件中

dtstofloat32)

ldflags="${ldflags} -ldts_pic"

為:

dtstofloat32)

ldflags="${ldflags} -ldts"

重新make

問題
