Bug#913871: [libboost-coroutine-dev] Projects using libboost-coroutine2 fails to compile with g++8 and -std=gnu++17
According to https://www.boost.org/users/history/version_1_68_0.html it seems 1.68 has some fixes for context & coroutine2: Context: #78: Linker error with context-impl=ucontext: multiple definition of boost::context::detail::current_rec Coroutine2: #14: crash while stack unwinding #20: failes to compile test in due to the error C2039 (looks similar with what I enounter on linux) [...] IMHO Debian buster should use 1.68 ... Cheers, BogDan.

I have a simple example:
[cpp]
#include
using YieldType = boost::coroutines2::coroutine::pull_type;
class Test {
public:
Test()
: m_coro(std::bind(&Test::callMe, this, std::placeholders::_1))
{}
void callMe(YieldType &yield) {}
using Call = boost::coroutines2::coroutine::push_type;
Call m_coro;
};
int main()
{
Test t;
return 0;
}
[/cpp]
$ g++ test.cpp -std=gnu++14 -lboost_coroutine -lboost_context
works just fine
$ g++ test.cpp -std=gnu++17 -lboost_coroutine -lboost_context
gives me following errors:

Will it be the default boost in buster ? Will you consider to bump 1.68? As I mentioned in my previous comment, it fixes some serious problems. Cheers, BogDan. P.S. I tried to clone https://salsa.debian.org/debian/boost-defaults.git to change it for 1.68 and to help your with a pach. But I could not find any docs about how to use & build it. Especially how to use "debian/create-boost-defaults-control.py". Will be great if you can add a README.md/txt file to debian folder which explains to begginers how to get started ;-).

Uploading a new version is extremely time consuming and there is no real indication on what benefits it provides. > P.S.

For the actual Boost package you should look at boost1.67. However, be warned: Boost is a very complicated piece of software, and boost1.67 is a rather complicated package, so it's not the right place for beginners. If you are a beginner, just use boost1.67, it will be more than ok for nearly anything you have to do. Giovanni. -- Giovanni Mascellani Postdoc researcher - Université Libre de Bruxelles
