And i have problem to compile the c++ code on windows. Did anyone of you have a good dicription that a normal people like me ould understand an can compile the 10.20 API c++ on windows. I would be very thankful if anyone of you could send me some information. Sorry again for this basic question. Best regards Thobi

Franco Chiesa Docampo #50667 开云体育 Hi Andrew, does this work for Visual Studio Code? Cheers, Frank toggle quoted message Show quoted text El 31 ene. 2023, a la(s) 16:43, Andrew Bannerman <bannerman1985@...> escribió: ?Good to hear :)? Regards Andrew
David Armour All Messages By This Member #50668 The TWS API source code comes with Visual Studio solution files which would only work with Visual Studio (not Visual Studio Code). You would have to make all the configs yourself to get running in VS Code but why bother when VS is also free and far better for debugging. Note someone mentioned below about switching to Win32. This is because the .SLN file only comes with Win32 configs but it is really easy to create x64 configs. Basically just duplicate the Win32 configs under x64. I use TWS API C++ under Visual Studio 2020 Preview with C++ Latest standard set with x64 configs and never have any problems. The biggest headache of recent has been the switch to DECIMAL. For that I use VCPKG and installed the "intelrdfpmathlib"? which covers all the Decimal Floating Point Math libraries you will need.

[email protected] All Messages By This Member #50686 Hi, another small and basic question. What is the difference between the TextClient and the TestClientstatic? Reards Thobias
David Armour All Messages By This Member #50687 This is more a general C++ compiling question. You can either link in libraries "statically" which means they are embedded in your .exe file, or they can be linked "dynamically" which means they call the library functions that reside in a .dll file that sits outside of your .exe file. The "supposed" benefit of using .dlls is that you can change the dll without changing your code, but I personally do not like to do that since the changes in dlls could break your code. It is really a matter of taste (and of course using DLLs means your ,exe size is much smaller). As for TwsClient and TwsClientStatic, they are the two versions mentioned above. One uses a .DLL (TwsSocketClient.dll) and the other gets statically linked to your code so does not need any DLL.

I have installed VCPKG and "intelrdfmathlib" but still getting 2 (3) errors trying to compile to x64. Severity Code Description Project File Line Suppression State Error LNK2019 unresolved external symbol __bid64_from_string referenced in function "unsigned __int64 __cdecl stringToDecimal(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >)" (?stringToDecimal@@YA_KV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z) TwsSocketClient C:\TWS API\source\CppClient\client\EDecoder.obj 1 I have changed configuration to x64 here Win32 does compile well but i would like to compile it to x64 if possible.
David Armour All Messages By This Member #50887 This linker error looks like it cannot find the intel math library. Did you install the intelrdfmathlib with the correct triplet to compile with x64? Make sure you install either: intelrdfpmathlib:x64-windows-static or intelrdfpmathlib:x64-windows depending whether you use static libs or not. You probably go Win32 to compile because you installed the Win32 lib.
