我如何获得项目他们构建输出放入与使用SCons相同的目录？ [英] How do I get projects to place their build output into the same directory with Scons?
本文介绍了我如何获得项目他们构建输出放入与使用SCons相同的目录？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
背景
我通过建立一个具有两个子项目基本的C ++示例项目尝试使用SCons：
- Prj1是取决于Prj2一个EXE
- Prj2是部分出口函数的DLL
我遇到的问题是，该库建立自己的OBJ，.PDB，.LIB，.DLL等文件在同一目录，因为它是SConscript文件，而EXE建立在同一个目录作为其文件其SConscript。该应用程序成功生成两个Prj2依赖和自身。但是，你不能运行产生的EXE，因为它无法找到它所需要，因为它是在其他目录库。
问题
我怎样才能有依赖性输出它们的二进制文件和调试信息到一个共同的目录，以便他们可以执行和调试多个项目？
可能的解决方案
这是我想到至今：
- 我试着用VariantDir（pviously称为BuildDir $ P $），但是这似乎并没有工作。也许我的东西搞乱这里。
- 我可能会告诉编译器和明确的连接（通过佛/依存为例），其中砸他们的文件（这是最好的或唯一的解决办法？）
- 在生成的二进制代码执行复制命令（这似乎是一个黑客，相当管理/维护疼痛）
更新
我更新了文件结构及以下文件的内容以反映工作液在它的全部内容。感谢哀悼他的洞察力。
命令
通过这种配置，您必须不幸被cd'ing到构建目录，然后运行以下命令执行构建。我需要一个正常工作的别名设置来解决这个问题。

解决方案
好吧第三次尝试是魅力。我只是把这个在一个新的答案，保持清洁。我跟我的本地scons的大师，他说，安装方法应该可行，但还有一个更简单的方法。
简单地定义你想要的可执行文件（或DLL）去的完整路径。所以：
prj2_env.Program（目标= os.path.join（BIN_DIR，PROG），源=来源）
如果你不希望有做这在所有的地方，你可以做一个全局函数：
DEF prefixProgram（ENV，TRGT，索马里红新月会）：
env.Program（目标= os.path.join（ENV。[MY_OUTPUT_DIR]，TRGT），源= SRCS）
然后在你的SConscript，是这样的：
导入（'prefixProgram'）
＃ 东东 ...
prefixProgram（prj2_env，PROG，来源）
请注意，您可以将自己的属性添加到环境，这是其中
ENV [MY_OUTPUT_DIR]
从何而来。我写这篇即兴，所以我们期待一些小的语法错误，什么不是。很明显，你可以使用同样的伎俩共享和静态库。
在充分披露的利益，我给我的本地scons的大师这个回答自己的机会，但他很害怕他会成为沉迷于网站和下降。 ：）
Background
I'm trying out Scons by setting up a basic C++ sample project that has two sub-projects:
- Prj1 is an EXE that depends on Prj2
- Prj2 is a DLL that exports some functions
The problem I'm running into is that the library builds its .obj, .pdb, .lib, .dll, etc. files in the same directory as it's SConscript file while the EXE builds its files in the same directory as its SConscript. The application successfully builds both the Prj2 dependency and itself. However, you cannot run the resulting EXE because it can't find the library it needs because it is in the other directory.
Question
How can I get multiple projects that have dependences to output their binaries and debug information into a common directory so that they can be executed and debugged?
Potential Solutions
This is what I have thought of so far:
- I tried using VariantDir (previously called BuildDir) however this doesn't seem to work. Perhaps I'm messing something up here.
- I could potentially tell the compiler and the linker explicitly (via Fo/Fd for example) where to drop their files (is this the best or only solution???)
- Execute a copy command on the resulting binaries (this seems like a hack and quite a pain to manage/maintain)
Update
I updated the File Structure and file contents below to reflect the working solution in it's entirety. Thanks to grieve for his insight.
Command
With this configuration, you must unfortunately execute the build by cd'ing to the build directory and then running the command below. I need to get a properly working alias setup to get around this.

解决方案
Ok Third try is a charm. I am just placing this in a new answer to keep it cleaner. I talked with my local scons guru, and he stated that the install method should work, but there is a much easier way.
Simply define the full path where you want the executable (or dll) to go. So:
prj2_env.Program(target = os.path.join(BIN_DIR,PROG), source = SOURCES )
If you don't want to have to do this in all places you can make a global function:
def PrefixProgram(env, trgt, srcs):
env.Program(target = os.path.join(env.["MY_OUTPUT_DIR"], trgt), source = srcs)
Then in your SConscript, something like:
import ('PrefixProgram')
# stuff ...
PrefixProgram(prj2_env, PROG, SOURCES)
Note that you can add your own attribute to the environment, which is where the
env["MY_OUTPUT_DIR"]
comes from. I wrote this off the cuff, so expect some minor syntax errors and what not. Obviously you can apply the same trick for shared and static libraries.
In the interest of full disclosure I offered my local scons guru the chance to answer this himself, but he was scared he would become addicted to the site and declined. :)
