[GiNaC-list] compiling date 22 / 03 / 2026

22 Mar 2026

      Greetings.

When I try to compile the latest version cloned from Git I get the 
following error:

add.cpp: In member function ‘void GiNaC::add::print_add_sorted(const 
GiNaC::print_context&, const char*, const char*, const char*, unsigned 
int) const’:
add.cpp:176:66: error: ‘std::ostream’ {aka ‘class 
std::basic_ostream<char>’} has no member named ‘str’
    sorted_seq.emplace((std::ostringstream{} << sortex << 
it.rest).str(), it);

I had been using the precompiled version that was included in OpenSuSE. 
Do I need to upgrade my installation?

Best regards,

Marko Riedel
