Hello all!

The CMake target libzstd_shared requires the file libzstd-dll.rc to expose library's symbols in DLL, when building with MSVC and configured to shared.

https://github.com/facebook/zstd/blob/72c16b187d27016b7634f5c6b7290e7c66ba44b3/build/cmake/lib/CMakeLists.txt#L125

Still, the file libzstd-dll.rc includes the public header zstd.h to be able to read those publuc methods.

https://github.com/facebook/zstd/blob/72c16b187d27016b7634f5c6b7290e7c66ba44b3/build/VS2010/libzstd-dll/libzstd-dll.rc#L4

The same does not occur with Linux/OSX, because only Windows needs that file to expose symbols.

To be able to access the zstd.h, CMake needs to know where this file is available. One way to do that is using the target_include_directories method, pointing a folder to be included to that CMake target only. The same is configured with the scope INTERFACE, which is only visible to the consumers of the target, not to the target itself. The result is follow error, because that folder is not visible when building on Windows (the OS does not matter).

In order to fix the situation, the zstd.h should be visible when both building the target, but also when consuming it. It describes the PUBLIC scope.

fixes #3999

OS: Windows 10 Compiler: Visual Studio 17 2022 CMake: version 3.29.0

This patch uses PUBLIC as scope to fix the current build.

Here is the build log using https://github.com/facebook/zstd/releases/download/v1.5.6/zstd-1.5.6.tar.gz without the patch.

@uilianries Zstd should not require the public include directory to build, because it uses relative includes. Is this a deficiency in the Windows cmake build, or have I misunderstood something about cmake?

Apr 01 '24 17:04 terrelln

I'm happy to accept the PR, I would just like to understand why this is happening first

Apr 01 '24 17:04 terrelln

@terrelln Sorry my delay. When building shared on Windows, in order to generate the DLL, the file libzstd-dll.rc will be consumed here: https://github.com/facebook/zstd/blob/72c16b187d27016b7634f5c6b7290e7c66ba44b3/build/cmake/lib/CMakeLists.txt#L125

Then, it requires zstd.h (the public header) too: https://github.com/facebook/zstd/blob/72c16b187d27016b7634f5c6b7290e7c66ba44b3/build/VS2010/libzstd-dll/libzstd-dll.rc#L4

However, properties marked as interface are only visible to the consumers of the target, not to the target itself. The result is follow error, because that folder is not visible when building the shared library on Windows.

Another option would be adding an expression to use PUBLIC or INTERFACE according to MSVC value, but I guess is too much.

Apr 02 '24 14:04 uilianries

Then, it requires zstd.h (the public header) too:

Thanks! I didn't even realize that that file existed! We've switched all of our other headers over to relative includes. Would it be possible to use a relative include for that file as well?

But this makes sense, and I will merge this PR. Could you please just add a comment explaining why it needs to be PUBLIC for Windows, so we don't accidentally remove it again in the future.

Apr 02 '24 17:04 terrelln

@terrelln I just updated the PR description with more details. Please, take a look.

About the relative include, do you mean changing the libzstd-dll.rc to include zstd.h from a relative path, like:

#include "../../../lib/zstd.h" /* ZSTD_VERSION_STRING */

It would work yes, it tested locally on Windows + CMake and compiled the DLL without errors. But is really fragile, as any layout change in the folder would break it. Plus, I see not only CMake is consuming the .rc file, but also Meson and VS2010, so would need to build with them too to make sure.

Apr 03 '24 07:04 uilianries

There is also #4019.

Apr 10 '24 04:04 dg0yt

I did run into the same issue. The PR worked for me. Thanks!

Apr 17 '24 14:04 bebuch

https://github.com/facebook/zstd/pull/4019 was merged, so this PR might be obsolete.

Apr 17 '24 15:04 dg0yt

Closing in favor of #4019
