Vcpkg: [dlib] Debug build fails with USER_ERROR_missing_dlib

Created on 6 May 2017 · 12Comments · Source: microsoft/vcpkg

I'm still getting this error at debug build:

error LNK2001: unresolved external symbol USER_ERROR__missing_dlib_all_source_cpp_file__OR__inconsistent_use_of_DEBUG_or_ENABLE_ASSERTS_preprocessor_directives_

I'm using Win10 x64 + VS2017 with all current Updates.

When building dlib-Release no errors occur. I've also updated my vcpkg to latest available version.
For testing purposes I did a debug-build with a separate dlib.lib in some other location (not related to vcpkg) and everything went fine.

According to https://github.com/Microsoft/vcpkg/pull/814 this problem shouldn't occur anymore.

Ok, so after running in circles for a long while, I figured out the problem.

Basically, dlib encodes the Debug/Release setting inside its header files. Since we only keep the release headers, this means we were dropping the ENABLE_ASSERTS setting on the floor.

I've added a post-build rewrite in port version 19.4-3 that should fix this by responding to the NDEBUG macro and setting ENABLE_ASSERTS accordingly.

In conclusion: you don't need the #ifndef in your code -- just update to the latest dlib port and everything should compile smoothly.

Thanks for reporting!

With the same setup (Win10 x64 + VS2017) I'm not able to reproduce this issue. Could you attach the debug log files (configure and build) or send them to [email protected]?

Hi,

Here's my debug-build log. Further below are my compiler/linker settings.

One issue: we should select Ninja for 64-bit windows, since it specifies PREFER_NINJA. We did have a regression approximately 4 days ago that was fixed by @muemart in eb3d052a that would account for this.

Second: I have no idea where stdafx.obj is coming from. There's no mention anywhere in the sources for stdafx.

Finally, looking at the sources for Dlib, I notice that it has optional support for BLAS/LAPACK/etc. These aren't listed as dependencies, so that could cause the difference in behavior that we're seeing. I've disabled all these non-listed dependencies and pushed 8e50c86 (port version 19.4-2). Please try pulling and building this version!

Hang on, I just realized you're saying that

vcpkg install dlib:x64-windows

compiles _just fine_, and it's actually your downstream project that doesn't compile.

It looks like Dlib has an optional DLIB_ENABLE_ASSERTS setting which we enable for debug builds.

You'll need to add

#ifndef _NDEBUG
#define ENABLE_ASSERTS 1
#endif

into your pch before including dlib.

Sorry for the confusion!

Too late...just recompiling the new dlib version 😄

I'm still getting the same error.

Just tried to compile it with

#ifndef _NDEBUG
#define ENABLE_ASSERTS 1
#endif

in my pch.

I think it's best to create a completely new project and try again. Although I'm using a demo project from dlib website there's always a potential for confusion.

Still getting the same error. Here's my project in a 7zip file.

Ok, so after running in circles for a long while, I figured out the problem.

Basically, dlib encodes the Debug/Release setting inside its header files. Since we only keep the release headers, this means we were dropping the ENABLE_ASSERTS setting on the floor.

I've added a post-build rewrite in port version 19.4-3 that should fix this by responding to the NDEBUG macro and setting ENABLE_ASSERTS accordingly.

In conclusion: you don't need the #ifndef in your code -- just update to the latest dlib port and everything should compile smoothly.

👍3

Yes, it works now. 😃

Many thanks 👍

Can you guys direct me how to update to the lastest dlib port in vs2017. Many thanks, i get the same errors and still stuck there
