[package] gamenetworkingsockets/1.4.1: Missing `__std_search_1` during linkage

[Emily-TTG]

Description

I'm encountering a linkage failure when Conan is building GNS with MSC tooling. The issue appears to be the same as is described here, though it was closed with no resolution: https://developercommunity.visualstudio.com/t/conan-Build-error-when-building-protobuf/10890512?sort=active

Package and Environment Details

• Package Name/Version: gamenetworkingsockets/1.4.1
• Operating System+version: Windows 11
• Compiler+version: MSC Tools v143
• Conan version: conan 2.25.1
• Python version: Python 3.13.3

Conan profile

Custom is:

include(default)

[settings]
compiler.cppstd=20

Default is:

[settings]
arch=x86_64
build_type=Release
compiler=msvc
compiler.cppstd=14
compiler.runtime=dynamic
compiler.runtime_type=Release
compiler.version=194
os=Windows
Build profile:
[settings]
arch=x86_64
build_type=Release
compiler=msvc
compiler.cppstd=14
compiler.runtime=dynamic
compiler.runtime_type=Release
compiler.version=194
os=Windows

Steps to reproduce

conan install -of .conan-Debug --build=missing --settings=build_type=Debug -pr:h=conanprofile.txt

Hi @Emily-TTG , thanks for reporting this.

I suspect this is one of those corner cases where objects built with a newer MSVC may not link on older msvc. You may be able to work around this by just telling Conan to rebuild from source (--build="*" instead of `--build=missing) - I'd be able to tell if you could provide the complete logs of the command you are running - as I need to check the exact recipe revisions and package revisions (so that we can tell if binaries from Conan Center are being downloaded) which package build is actually failing, as well as which version of msvc it is using - thanks!

Apologies I no longer have access to the full log, and have updated my VC env which made the problem go away. I can confirm both GameNetworkingSockets and Protobuf were being built from source.

Following the conan graph output:
self.requires("gamenetworkingsockets/1.4.1") -> protobuf/3.21.12
