[flac-dev] Trying to link against libFLAC_static.lib (windows)

[Glenn McCord]

Hi. I'm trying to get a project linking to libFLAC_static.lib but I
get linker errors such as the following.

6>AudioDecoder.lib(CFlacDecoder.obj) : error LNK2019: unresolved

The __imp__ prefix seems to imply that some kind of .dll usage is
happening, which it shouldn't.

All I need is the C lib, so I just build libFLAC_static from within
VS2010 (I've converted the VS2005 project)

I've then linked to that library by setting the linker settings
General-> "Additional Library Dependencies" and Input-> "Additional
Dependencies" appropriately.

Both the main app and the flac libs are build using the "runtime
library" Multi-Threaded /MT (or /MTd for debug mode)

The flac project is using the preprocessor definitions:

WIN32
NDEBUG
_LIB
FLAC__HAS_OGG
FLAC__CPU_IA32
FLAC__HAS_NASM
FLAC__USE_3DNOW
VERSION="1.2.0"
FLAC__NO_DLL

I'm not sure what else to try at this stage. I've reached the point
where I start going in circles and accessing the same internet search
results. Has anyone got any suggestions?

Thanks
