package abseil/20210324.1: Linker error while using absl::SimpleAtob(absl::string_view, bool *)

[abhijith96]

Linker Error while using abseil from conan repository. I have build a simple project using abseil as dependency.

Conan install went smoothly. while building my sample project i got a linker error while using
absl::SimpleAtob function. Rest of the functions in abseil were working correctly.

project link. Here i have made two executable. one of them using absl::SImpleAtob and another using absl::flat_hash_set. The executable using flat hash set builds and runs fine. The problem is only with absl::SimpleAtob function.

Yes, I can reproduce this issue when C++ standard of consumer project is C++17. Try to set compiler.cppstd to 17 in your profile and build abseil from source.

thank you, it worked. is there a way to do this without setting cpp standard. because some of the packages that i use does not have cpp 17 support.
is there a workaround to do this.
