Error ___iob_func

[Karbust 4737]

Hello

I just upgraded recently to vs 2017, but my client source is for vs 2013

It is compiling fine, but at the end I get this error:

Error	LNK2001	unresolved external symbol ___iob_func	UserInterface	D:\client_reboot_dev - Copy\vs_files\UserInterface\libjpeg-9aMT.lib(jerror.obj)	1	

How can I solve this?

Thanks

You download 

libjpeg-9aMT source and compile lib vs2017 vc140/141

How can I do that? I already downloaded this one: http://www.ijg.org/files/jpegsr9a.zip

But there's no sln file to use on Visual Studio, how can I manage to create one? And being able to create the MT version?

Thanks for the answer

I was able to compile with this one: http://www.dahlsys.com/misc/compiling_ijg_libjpeg/

I saw that one to, but I didn't understood a few steps, with this one, I was able to build and now I can compile my client source...

And I ended up upgrading from libjpeg-9a to libjpeg-9b...

This warnings are important?

I no longer compile those libs manually, I install them through vcpkg:

ijg-libjpeg:x86-windows-static, version 9e#1

 

Plus, on my last post in this topic I said what worked for me when I compiled the libs.
