Specify library name and version: tinycthreadpool/1.0

This is a portable C threadpool. It is based on tinycthread and supports both Windows and POSIX systems.

• I've read the contributing guidelines.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the conan-center hook activated.

Thank you for your contribution. I see you are using Conan in your project already 😸

[bennyhuo]

I have updated the recipe to make all the checks passed. Please let me know if there is something else to do to meet the requirements. Thanks.

@uilianries Hi there, I just wonder when can we have this pull request merged? Are there any problems I need to fix? : )

[uilianries]

@bennyhuo Thank you for your contribution! Please, take a look on my review

[uilianries]

@bennyhuo no fPIC neither shared option support? Does tinycthreadpool only supports static library?

[bennyhuo]

I have some concerns about this project, since it's a fork we usually do not allow those

and when they add enough value we ask for teh author prefix... but when I was looking into I noticed this has a copy of

https://github.com/tinycthread/tinycthread

embeeded inside ... which is fine but for conan that would ideal be a dependency since people could want to use two lirbaries that depend on it this and something else that would hit linkage issues.

Have you considered linking against this library instead of copying it?

I have tried, but the recipe does not work well with the new conan version. Any suggestions? @prince-chrismc

Hello, any news about this? @prince-chrismc

[prince-chrismc]

I'd suggest updateting you build script to link against the original library instead of trying to duplicate it, I made #17001 which is pretty small and will support v2

but we can make sure everything works with v1 in the mean time

Great. I shall update my project after #17001 merged. Thanks.
