undefined symbol: _ZN5Yosys8Frontend7executeESt6vectorINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEESaIS7_EEPNS_5RTLIL6DesignE

[gkamendje]

Using version 3d041df
OS= CentOS Linux release 7.9.2009
I am running Centos7 and I was able to compile and install as reported here #1826. However, I get the message undefined symbol: _ZN5Yosys8Frontend7executeESt6vectorINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEESaIS7_EEPNS_5RTLIL6DesignE
when I try to load the module in Yosys.

Yosys 0.13+15 (git sha1 bc027b2ca, gcc 8.3.1 -fPIC -Os)

ERROR: Can't load module `./systemverilog': /my_path/OpenROAD-flow-scripts/tools/install/yosys/bin/../share/yosys/plugins/systemverilog.so: undefined symbol: _ZN5Yosys8Frontend7executeESt6vectorINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEESaIS7_EEPNS_5RTLIL6DesignE

Any hint what is going on?

It means that the plugin is referencing to _ZN5Yosys8Frontend7executeESt6vectorINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEESaIS7_EEPNS_5RTLIL6DesignE symbol that is not in the yosys binary.

echo "_ZN5Yosys8Frontend7executeESt6vectorINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEESaIS7_EEPNS_5RTLIL6DesignE" | c++filt 
Yosys::Frontend::execute(std::vector<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > >, Yosys::RTLIL::Design*)

Most probably it means that the signature changed.

The pinned version to this repo is currently https://github.com/YosysHQ/yosys/tree/8b2a0010216f9a15c09bd2f4dc63691949b126df which is newer (0.33+34) so I would suggest using a newer yosys version.

I got the following error message while trying to use it with the latest version of Yosys (b84ed5d3ad2ac8b533e1d6a83dbdb6d5c2be9ce7). I am running ./build_binaries.sh -y. My version of the plugin is bc99d46

I noticed that the file kernel/fmt.h does not exists in the include subdirectory of the Yosys installation directory. So copied it from the Yosys compilation directory and now I am getting the following error:

[gkamendje]

looks like the issue is reported in #1961

[pgielda]

Yes, it will be fixed via #2008

[alaindargelas]

This is fixed with the latest version.
