Build Errors in reproc Package - Declaration Conflict with reproc++ (Required for zrhtym Installation)

[mene311]

Introduction:
I am encountering build errors while trying to install the "reproc" package on Arch Linux. The error seems to be related to a declaration conflict with "reproc++," which results in changes of meaning for certain variables. It is worth noting that I am installing the "reproc" package as it is a prerequisite for the installation of "zrhtym."

Error Messages:
During the installation process, the following errors were encountered:

make: *** [Makefile:146: all] Error 2

Expected Outcome:
I expected the "reproc" package to be installed successfully without any build errors, as it is a prerequisite for the installation of "zrthym."

Steps Taken So Far:
I have attempted to install the "reproc" package using yay -S reproc, and also tried the temporary fix by setting the CXXFLAGS environment variable to -Wno-changes-meaning, but the build errors persist.

System Information:

Arch Linux 
Compiler version: GNU 13.1.1

Request for Assistance:
I kindly request assistance from the "reproc" community to resolve the build errors encountered during the installation of the "reproc" package. The package is essential as it serves as a prerequisite for installing "zrthym." Any guidance, suggestions, or possible solutions to address the declaration conflict with "reproc++" would be highly appreciated.

Conclusion:
I am experiencing build errors while installing the "reproc" package on Arch Linux due to a declaration conflict with "reproc++." It is important to note that "reproc" is required as a prerequisite for the installation of "zrthym." I have provided the error messages, system information, and details about the attempted temporary fix. I am seeking assistance from the "reproc" forum or community to find a proper solution to this issue. Thank you for your time and support.

possible duplication of #94

I got the same issue when building it as a dependency of the aur package micromamba 1.4.9-1 today.
