ubuntu - 如何在 ubuntu 上运行 steamworks 示例

Question

我下载了the Steamworks SDK .

里面有一个 Steamworks 示例。当我执行命令 make在 steamworksexample文件夹失败并出现错误:

steam/sdk/steamworksexample$ make steam/sdk/steamworksexample/../tools/linux/bin/g++ -g -DPOSIX -DSDL -I/home/steam/sdk/steamworksexample/../tools/linux/runtime/i386/usr/include/SDL2 -D_REENTRANT -DGNUC -O0 -I/home/steam/sdk/steamworksexample/../public -DDEBUG   -c Inventory.cpp -o debug/Inventory.o -MD -MF debug/Inventory.dep

Inventory.cpp: In member function 'void CSpaceWarLocalInventory::OnSteamInventoryFullUpdate(SteamInventoryFullUpdate_t*)': Inventory.cpp:61:61: error: 'nullptr' was not declared in this scope Inventory.cpp: In member function 'void CSpaceWarLocalInventory::OnSteamInventoryResult(SteamInventoryResultReady_t*)': Inventory.cpp:131:62: error: 'nullptr' was not declared in this scope Inventory.cpp: In member function 'void CSpaceWarLocalInventory::DoExchange()': Inventory.cpp:218:18: error: 'nullptr' was not declared in this scope Inventory.cpp: In member function 'void CSpaceWarLocalInventory::GrantTestItems()': Inventory.cpp:243:35: error: 'nullptr' was not declared in this scope Inventory.cpp: In member function 'const CSpaceWarItem* CSpaceWarLocalInventory::GetItem(SteamItemInstanceID_t) const': Inventory.cpp:254:9: error: 'nullptr' was not declared in this scope Inventory.cpp: In member function 'const CSpaceWarItem* CSpaceWarLocalInventory::GetInstanceOf(SteamItemDef_t) const': Inventory.cpp:276:9: error: 'nullptr' was not declared in this scope Inventory.cpp: In member function 'void CSpaceWarLocalInventory::RefreshFromServer()': Inventory.cpp:283:33: error: 'nullptr' was not declared in this scope make: *** [debug/Inventory.o] Error 1

我正在使用 Ubuntu 14.04.3 LTS。

我刚刚得到了 steamworks 示例，可以在我的 Ubuntu 14.04 计算机上构建和运行。我没有很好的解决方案，但有一些 hacky 解决方案。

简短的解决方案是运行(您需要在此处修改包含路径到您拥有此代码的任何目录):

make CFLAGS="-std=c++0x -include /home/bbales2/sdk/public/steam/steamtypes.h -I/home/bbales2/sdk/tools/linux/runtime-release/amd64/usr/include/SDL2/ -DSDL=1"

这将编译一些东西，但会 失败编译“glew.c”。要编译此文件，您需要从该 make 中删除 steamtypes 包含并再次运行它，如下所示:

make CFLAGS="-std=c++0x -I/home/bbales2/sdk/tools/linux/runtime-release/amd64/usr/include/SDL2/ -DSDL=1"

glew.c 编译后，make 会再次失败。重新运行第一个 make 命令，最终事情应该完成。使用“debug/SteamworksExample.sh”运行示例

更详细地说，我遇到的错误列在这里。我们可以用 CFLAGS 修复它们:

error: 'nullptr' was not declared in this scope

要解决这个问题，你需要告诉你的编译器是 C++11。这是“-std=c++0x”标志

GameEngine.h:129:52: error: 'uint32' has not been declared
GameEngine.h:129:67: error: 'uint32' has not been declared
GameEngine.h:132:52: error: 'byte' has not been declared
GameEngine.h:132:65: error: 'uint32' has not been declared
GameEngine.h:132:80: error: 'uint32' has not been declared
GameEngine.h:135:52: error: 'DWORD' has not been declared

有一个 header sdk/public/steam/steamtypes.h 定义了这些。由于某种原因，默认情况下它没有被包含在内。这是“-include/home/bbales2/sdk/public/steam/steamtypes.h”标志。

gameenginesdl.h:18:17: fatal error: SDL.h: No such file or directory

缺少 SDL header 。 Valve 将它们包含在 sdk/tools/linux/runtime-release/amd64/usr/include/SDL2/中，但 Makefile 没有检测和添加它们。这是“-I/home/bbales2/sdk/tools/linux/runtime-release/amd64/usr/include/SDL2/”标志。

In file included from <command-line>:0:0:
/home/bbales2/sdk/public/steam/steamtypes.h:107:15: error: variably modified 'Salt_t' at file scope
/home/bbales2/sdk/public/steam/steamtypes.h:123:1: error: initializer element is not constant
make: *** [debug/glew.o] Error 1

我们收到此错误是因为我们在编译此文件时无法包含 steamtypes.h(使用 -include 标志强制包含这样的内容不是一个好主意)。只需删除 steamtypes 包括，重新运行 make 来编译这个文件，然后添加 steamtypes include 回来(对于编译的其余部分)似乎工作。

和

Main.cpp:248:2: error: #error Need CreateGameEngine()
... (bunch of Warnings)
Main.cpp: In function 'int RealMain(const char*, HINSTANCE, int)':
Main.cpp:251:2: error: expected primary-expression before 'if'
Main.cpp:251:2: error: expected ',' or ';' before 'if'
make: *** [debug/Main.o] Error 1

Main.cpp 似乎要我们定义 SDL 宏。我们用“-DSDL=1”来做到这一点
