With dev-libs/boost-1.77.0-r3 installed, save the following code as main.cxx : > #include <boost/process.hpp> > > int main(int argc, char *argv[]) > { > boost::process::spawn("ls"); > > return 0; > } Compile it with : > $ g++ main.cxx -o out -std=c++14 -Wfatal-errors You'll get : > In file included from /usr/include/boost/process/detail/basic_cmd.hpp:14, > from /usr/include/boost/process/args.hpp:33, > from /usr/include/boost/process.hpp:22, > from main.cxx:2: > /usr/include/boost/process/detail/traits/wchar_t.hpp: In static member function 'static std::vector<std::__cxx11::basic_string<wchar_t> > boost::process::detail::char_converter<wchar_t, std::vector<std::__cxx11::basic_string<char> > >::conv(const std::vector<std::__cxx11::basic_string<char> >&)': > /usr/include/boost/process/detail/traits/wchar_t.hpp:150:14: error: 'transform' is not a member of 'std' > 150 | std::transform(in.begin(), in.end(), ret.begin(), > | ^~~~~~~~~ > compilation terminated due to -Wfatal-errors. Same code builds fine with dev-libs/boost-1.76.0-r1. Upstream patch to fix build failure : https://github.com/boostorg/process/commit/e08374ed95ac33865bda40602c94909e7cd9607f Reproducible: Always
Created attachment 757121 [details] main.cxx test case > $ g++ main.cxx -o out -std=c++14 -Wfatal-errors Builds fine with dev-libs/boost-1.76.0-r1. Don't build with dev-libs/boost-1.77.0-r3.
