Title: One unresolved external symbol in Image.cpp.obj
Post by: Tez on May 27, 2018, 04:12:20 am

Having problems setting up my SFML project. I noticed that in an old sfml project (2.4.2) I had made I had included "jpeg.lib", however it is not included in this project. I couldn't find it. Could that be the problem?

VC++ 2017 on x64 windows host building for x86 with SFML version 2.5.0

Linker error message:

(click to show/hide)

LNK2019   unresolved external symbol ___std_swap_ranges_trivially_swappable_noalias referenced in function "unsigned char * __cdecl std::_Swap_ranges_unchecked<unsigned char,0>(unsigned char * const,unsigned char * const,unsigned char * const)" (??$_Swap_ranges_unchecked@E$0A@@std@@YAPAEQAE00@Z)   [...]\sfml-graphics-s-d.lib(Image.cpp.obj)

My linker dependency list for debug config:

libjpeg was removed in SFML 2.5 (https://github.com/SFML/SFML/issues/1278), so that shouldn't be the issue.

It there shouldn't be an issue unless you're trying to do something with it. Are you trying to link jpeg.lib?

I am not trying to link against libjpeg

Nothing easier than to search the error message and you'd get multiple hits on this forum alone. ;)
