Bug ID: 258740
Summary: Link fails with 'ld: error: undefined hidden symbol'
for no apparent reason
Product: Base System
Version: 13.0-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: misc
Assignee: [email protected]
Reporter: [email protected]
I am trying to update the port math/rumur to 2021.08.28:
1. Change VERSION in /usr/ports/math/rumur/Makefile to 2021.08.28
2. make makesum
3. make
This fails with:
> ld: error: undefined hidden symbol:
> rumur::parse(std::__1::basic_istream<char, std::__1::char_traits<char> >&)
> >>> referenced by main.cc
> >>>
> >>> murphi2murphi/CMakeFiles/murphi2murphi.dir/src/main.cc.o:(main)
>
> ld: error: undefined hidden symbol: rumur::resolve_symbols(rumur::Model&)

> c++: error: linker command failed with exit code 1 (use -v to see invocation)
The 'resolve_symbols' symbol is in the library:
> $ nm work/.build/librumur/librumur.so | grep resolve_symbols | c++filt
> 0000000000079b70 T rumur::resolve_symbols(rumur::Model&)
It's unclear what do error messages mean.
