URLProtocolManager.h patch submission for Windows #289

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Attemping to build the latest xuggler 5.0 from GIT (2012-02-12), I ran into a 
problem linking. The fix I found required modifications to the 
URLProtocolManager.h file, specifically to export the findHandler method. 
Changes were:

1) Include the io header file
#include <com/xuggle/xuggler/io/io.h>

2) Export the method using the macro from io.h
VS_API_XUGGLER_IO static URLProtocolHandler* findHandler(const char* url,

The error was discovered while attempting to build Xuggler latest from the GIT 
repo (2012-02-12).

System configuration:

Windows 7
MinGW 32bit (using msys)
configure --disable-captives

FFMPEG version 0.10 build
SDL 1.2
./configure --enable-shared --enable-w32threads

What steps will reproduce the problem?
1. Build xuggler on windows 7, 32bit using mingw and visual studio

Result, failing linking libxuggle-xuggler with libxuggle-xuggler-io:
