[pHash-support] Windows/MSYS configure error - Cannot find MMPEG

[George Tsiolis]

Evan,

I had already compiled the ffmpeg with --enable-shared and checked libraries 
were alright. The problem seemed to be the DLLs, so

here is how I solved the problem configuring pHash although there are more 
problems compiling the project now.

I built ffmpeg using : ./configure --disable-mmx --enable-shared 
--disable-static --enable-memalign-hack --target-os=mingw32 
-–extra-ldflags=-L/usr/local/lib --extra-cflags=-I/usr/local/include

AFTER the 'make install' I copied the DLLs files from /usr/local/bin to 
/usr/local/lib and that seems to solve the problem. FFMPEG can be found from 
configure script of pHash.

probably the ./configure last two parameters where not necessary but 
nevertheless I did not have time to check this out

I used the same, more or less, parameters to compile libjpeg. However the 
version 8b was not successfull so I did use the version 8a (jpegsr8a.zip). Hopefully
this is not the root of the compiling problem that follows ;)

now the problem part for the pHash 0.9 is make. I have successfully done the 
procedure under Ubuntu 9.04 (with some quirks for making the JNI work) and I am 
trying to make it for Windows XP Pro with MinGW/MSYS (1.5.6/1.10)

so after configuring pHash I run make and it seems it cant find the sys/mman.h so
I removed it (I read somewhere that mingw does not have a mman.h so I gave it a 
try) 
then I run make again with the following result:

$ make

I have copied the CImg.h in the pHash/src folder (i did the same for Ubuntu) 
and I cant really understand what the problem is here, it seems CImg problem 
icluding the libjpeg.h

any ideas?

thanx,
George

    George,

    Did you configure FFmpeg with --enable-shared? I don't think it builds
    shared libraries by default. You can check /usr/local/lib and see if
    there is a libavcodec.so there.
    Evan
