c++ - Abnormal unresolved external symbol error -

c++ - Abnormal unresolved external symbol error -

i have project used compile fine, using freetype library.

since os has been reinstalled , hence has visual studio 2010.

i have re-included , reinstalled of .lib .dll , header files. reason if run programme release configuration runs fine. if switch on debug config, gives me unresolved external symbol errors linker, on freetype library functions.

now i'm sure c++ directories both configurations identical re-set them using all-configurations tab in solution settings. this, both configurations "additional directories/additional dependancies settings", set identically in same way.

the difference find between release , debug folders in project folder, presence of file in debug folder called "vc100.idb", minimum rebuild dependancy file. looked promising, removing yielded no results, set back.

do have ideas of causing difference between configurations compiling?

worst come worst, can go on programming on release config, i'd rather not go on downwards road i'd know root of problem.

thanks in advance,

guy

the errors:

edit: ok strange. i've removed all of freetype directory info rom include , library directory setting in release config, additional dependancies. , released config version still works!

this leading me believe there missing (vs config-wise) moving files over.

i had same problem.

i solved compiling freetype( freetype-2.5.2\builds\windows\vc2010\freetype.sln ) solution x64 platform (or win32 if utilize it).

you .libs platform.
