[Bf-committers] Multiple compiling errors with libraries (-lpng, lfreetype, -ltiff)

[Kursad Karatas]

Hi

I am trying to build the latest Blender svn on Windows using 
Mingw-32bit, Cmake, Eclipse(Indigo) and also with QtCreator.  For some 
reason I am unable to past this stage. Qtcreator gives me the exact same 
message. I was not able to compile with Scons either.

I have compiled the Boost1.49  libraries with Bjam for Mingw, and 
additional zlib and png libs(tried different version) and they are all 
residing in standard MingGW folders but those steps did not help me 
either. I have all the Blender external libs from svn repos (mingw, 
mingw64 and windows). And I know that there are png libs there. I am 
really puzzled that it cannot find the png. I have directed Eclipse to 
add the -l directive with png libs (tried multiple versions). but that 
did not do much either.  The compiler compiles %100 then after linking 
stage I believe I am stuck.

I am wondering if anyone else on the list had similar compiler issues.  
Maybe it is a configuration problem. I am not able to distinguish the 
issue at this point. I am not sure if this is directly to do with the 
png or tiff libraries.

Here is the Cmake skips
