#657 | fixed | Cannot compile LEMON with MSVC and clang | ||
Description |
Hi! I've been successfully using LEMON in my project in a linux environment using gcc compiler. However when building for windows and macos I've run into the following problems:
2>main.obj : error LNK2019: unresolved external symbol "public: __cdecl lemon::bits::WinLock::WinLock(void)" (??0WinLock@bits@lemon@@QEAA@XZ) referenced in function "public: __cdecl lemon::bits::Lock::Lock(void)" (??0Lock@bits@lemon@@QEAA@XZ) 2>main.obj : error LNK2019: unresolved external symbol "public: __cdecl lemon::bits::WinLock::~WinLock(void)" (??1WinLock@bits@lemon@@QEAA@XZ) referenced in function "public: __cdecl lemon::bits::Lock::~Lock(void)" (??1Lock@bits@lemon@@QEAA@XZ) 2>main.obj : error LNK2019: unresolved external symbol "public: void __cdecl lemon::bits::WinLock::lock(void)" (?lock@WinLock@bits@lemon@@QEAAXXZ) referenced in function "protected: void __cdecl lemon::AlterationNotifier<class lemon::DigraphExtender<class lemon::ListDigraphBase>,class lemon::ListDigraphBase::Arc>::attach(class lemon::AlterationNotifier<class lemon::DigraphExtender<class lemon::ListDigraphBase>,class lemon::ListDigraphBase::Arc>::ObserverBase &)" (?attach@?$AlterationNotifier@V?$DigraphExtender@VListDigraphBase@lemon@@@lemon@@VArc@ListDigraphBase@2@@lemon@@IEAAXAEAVObserverBase@12@@Z) 2>main.obj : error LNK2019: unresolved external symbol "public: void __cdecl lemon::bits::WinLock::unlock(void)" (?unlock@WinLock@bits@lemon@@QEAAXXZ) referenced in function "protected: void __cdecl lemon::AlterationNotifier<class lemon::DigraphExtender<class lemon::ListDigraphBase>,class lemon::ListDigraphBase::Arc>::attach(class lemon::AlterationNotifier<class lemon::DigraphExtender<class lemon::ListDigraphBase>,class lemon::ListDigraphBase::Arc>::ObserverBase &)" (?attach@?$AlterationNotifier@V?$DigraphExtender@VListDigraphBase@lemon@@@lemon@@VArc@ListDigraphBase@2@@lemon@@IEAAXAEAVObserverBase@12@@Z) 2>main.obj : error LNK2001: unresolved external symbol "struct lemon::Invalid const lemon::INVALID" (?INVALID@lemon@@3UInvalid@1@B) 2>D:\Git\mbt-repository\build\Debug\mbt-fw-release.exe : fatal error LNK1120: 5 unresolved externals It seems there are some linking issues with LEMON however I was unable to fix the problem.

I would be very thankful for any feedback, these issues prevent us from making our software fully platform independent. |

#654 | duplicate | compile with c++20 standard | ||
Description |
Hi, I am not able to compile my project in CXX_STANDARD 20 (g++-10). I'm getting error: error: 'lemon::ArrayMap<lemon::DigraphExtender<lemon::ListDigraphBase>, lemon::ListDigraphBase::Node, lemon::ListDigraphBase::Arc>::Allocator' {aka 'class std::allocator<lemon::ListDigraphBase::Arc>'} has no member named 'destroy' 320 | allocator.destroy(&(values[id]));
The reason is that Is there any change to make Lemon work with C++20? Thanks! Best regards |
