[dmn-star]

is POCO static compiled?

[paulocoutinhox]

Hi @dmn-star,

Yes. Im using default options.

[paulocoutinhox]

I tried version 1.9.4 and 1.10.1.

But always problem with net/ssl.

[dmn-star]

Please ensure that the preprocessor define POCO_STATIC is set.

To link statically, the code using the POCO C++ Libraries must be compiled with the preprocessor symbol POCO_STATIC defined.

I have the same error:

Somehow there are two libraries PocoNetSSLWinmdd.lib and PocoNetSSLmdd.lib which exist simultaneously on Windows, share a lot of symbols and that causes link errors.
I think the error is how Poco is built in Conan under Windows.

[paulocoutinhox]

Hi,

I solved the problem:

On Windows you need set the options as this:

https://github.com/ezored/ezored/blob/master/files/targets/windows_app/conan/recipe/conanfile.py#L33-L35

Thanks.

[mathbunnyru]

I think the proper way to solve the problem for CCI is to make POCO work well under Windows by default.
I will create the PR later.
