[Solved] Problem with CMake CEGUI 0.8.2: Can NOT find SILLY

[odedsh]

Hi,

I'm trying to compile CEGUI for the first time. I am using CMake 2.8 and CEGUI 0.8.2. I am using MinGW32 and gcc 4.7.2
I used the dependencies pack for 0.8 and compiled it successfully for release & debug (I believe)

Currently when I am using CMake to generate make files I get the following output:

However my relevant Cache Entries are:

CEGUI_BUILD_IMAGECODEC_SILLY:BOOL=ON
//preprocessor definitions
SILLY_DEFINITIONS_STATIC:STRING=SILLY_STATIC

//Path to a file.

SILLY_LIB_STATIC_DBG:FILEPATH=C:/Cpp/cegui-deps-0.8.x-src/dependencies/lib/static/libSILLY_d.a

I checked and double checked that the paths above are correct.

If I try to Make CEGUI despite this then I get the following error:

And sure enough `includes_CXX.rsp` does not contain the include path to SILLY: C:/Cpp/cegui-deps-0.8.x-src/dependencies/include
(link.txt do not contain the relevant -l / -L for SILLY)

I suspect that since CMake complained about failing to find the library it didn't correctly configure the -I / -L settings in the makefile. But I am not sure which variables I should tweak so it would find the SILLY library. Anyone can help?

I think the problem is with finding libpng..
In FindSilly.cmake:
cegui_find_libraries(SILLY_LIB_STATIC "libpng;jpeg" static)
cegui_find_libraries(SILLY_LIB_STATIC_DBG "libpng_d;jpeg_d" static)

After these calls SILLY_LIB_STATIC is replaced with `libpng-NOTFOUND`..

Alright, Figured that all my problems were down to the fact that CMAKE_PREFIX_PATH is configured under the assumption that all the dependencies are compiled to:
<CEGUI_DIR>/dependencies (lib & include etc..)

I have them at:
C:/Cpp/cegui-deps-0.8.x-src/dependencies

Fixed the path in CMake and my problems disappeared. I will check the wiki again cause I didn't see anything about where to put the dependencies so CEGUI Cmake will pick them up quickly.

Hi, sorry for the late response..

The info on this can be found here:
http://static.cegui.org.uk/docs/current ... _deps.html
This page describes that the folder has to be called "dependencies" and is supposed to be in the main cegui source directory.

In general it is better to rely on the API docs rather than the wiki. Wiki is for additional things, API is for the core functionality and is also updated by the developers regularly, while the wiki is rather a community thing or for Todos and special applications.
