Errors while Compiling Source files

[Hadiiiiiiiiiiiiii]

When trying to compile prog\gameLibs\gamePhys\common\polares.cpp with LLVM i get this:

 polares-1dcf16.obj : error LNK2019: unresolved external symbol "void __cdecl sincos(float,float &,float &)" (?sincos@@YAXMAEAM0@Z) referenced in function "class Point2 __cdecl gamephys::calc_c(struct gamephys::Polares const &,float,float,float,float)" (?calc_c@gamephys@@YA?AVPoint2@@AEBUPolares@1@MMMM@Z)

polares.exe : fatal error LNK1120: 3 unresolved externals

am i using the wrong compiler/version? has anyone else been able to actually edit any of the source code?

What sample/tool do you build? All code is supposed to be built without problems using LLVM 15.0.7 and vc2019. Did you run make_devtools.py to construct (and download required) devtools folder? Did you have LLVM installed before running script and what version? I think script take the one LLVM is finds and doesn't check version of compiler.

[praetorii]

not trying to build any sample or tool, just trying to compile prog\gameLibs\gamePhys\common\polares.cpp to see the flight model polar calculations. make_devtools.py ran and installed all the devtools, had llvm 17.0.3 installed prior

All code is supposed to be built without problems using LLVM 15.0.7 and vc2019.

with 15.0.7 installed and when trying to run the polares.cpp file this is the output im gettting now:

Hadi> & 'C:\Program Files\LLVM\bin\clang++.exe' .\polares.cpp

What sample/tool do you build?

like what praetorii said, im not trying to bulid any tool, i just want to use the wave drag calculations in the polares.cpp file for one of my own projects, i had also already ran make_devtools.py

do you use jam to build this lib? just tried, both jam and jam -sPlatformSpec=clang compiles without error apparently you cannot compile with just clang++.exe' .\polares.cpp because file uses includes from DagorEngine

[Hadiiiiiiiiiiiiii]

just tried, both jam and jam -sPlatformSpec=clang compiles without error

sorry if this is a dumb question but how am i supposed to use any functionality of the polares.cpp now then? i understand that jam bulids a static library, but how am i supposed to use it?

You are not forced to use any code of DagorEngine separately in your build environment. But if you want to use it you should understand on your own how compilation works, what headers this polares.cpp depends on and how to change copy of this file (imported to your project) so it compile. DagorEngine is framework, not a list of independent code snippets.

[Hadiiiiiiiiiiiiii]

thats not really an answer...? how is anyone supposed to use/change/improve any of the source code if we cant import it into an IDE?

[OshidaBCF]

in a small nutshell

Gaijin cannot teach you how to code in c++

They said they'll make more documentations to build and use the engine soon:tm:

just trying to include the polares.h file gives so many errors

and yes it is using LLVM 15.04 and i have vc 2019

Part of the course when doing anything in c++

You can't include "just" polares.h, you also need to included EVERYTHING that is included in polares, this include files but also definitions that might happen somewhere that isn't included in polared but is in the file that is including polares.

i too wish it was that simple

for now it's probably better to wait for the devs to put a big documentation that'll explain everythin.

It seems you didn't define _TARGET_SIMD_SSE Refer to prog/_jBuild/win32/vc15-sets.jam (e.g.) to see macros it defines (and they are needed to compile engine)

local _DEF_C_CMDLINE =
