问题描述
在大多数Visual Studio(2008，但我怀疑这很重要)项目中进行构建时，如果存在错误，它将列出带有错误的文件的绝对路径.像这样(忽略特定错误-我有意添加了这些错误):
When building in most Visual Studio (2008, but I doubt it matters) projects, if there is error, it lists the absolute path of the file with the error. Like this (ignore the specific errors--I added them intentionally):
1>dope_external.cpp
1>c:\users\me\dope_external.cpp(4) : error C2144: syntax error : 'void' should be preceded by ';'
1>c:\users\me\dope_external.cpp(4) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
1>Generating Code...
但是，我当前正在使用的解决方案/项目列出了相对路径名:
However, the solutions/projects I'm currently working with list relative path names:
1>FileBasedEffect.cpp
1>..\..\..\..\..\..\..\..\tools\blah\code\src\important_file.cpp(10) : error C2653: 'FusionEffectKeys' : is not a class or namespace name
1>..\..\..\..\..\..\..\..\tools\blah\code\src\important_file.cpp(10) : error C2143: syntax error : missing ';' before 'const'
1>..\..\..\..\..\..\..\..\tools\blah\code\src\important_file.cpp(10) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
这会在Visual Studio中以及如果我从命令行或使用vcbuild在另一个环境中进行构建时发生.我想至少在实验中使用不同的环境来构建.但是相对的路径让我有点沮丧.
This happens in Visual Studio and also if I build from the command-line or in another environment using vcbuild. I'd like to use a different environment to build, at least as an experiment. But the relative paths are horking me a little.
我在项目属性中没有发现任何明显的差异，例如"UseRelativePathsInBuildErrors"，但是我不太了解构建系统.有任何想法吗?谢谢.
I don't spot any differences in the project properties that are obvious like "UseRelativePathsInBuildErrors", but I don't know the build system that well. Any ideas? Thanks.
推荐答案
我找到了解决方案.
在项目属性->配置属性-> c/c ++->高级中，有一个使用完整路径"选项似乎使vcbuild通过/FC 标记为cl.exe.这样会在输出中产生完整路径.
In project properties->configuration properties->c/c++->Advanced, there is a "Use Full Paths" option which appears to make vcbuild pass the /FC flag to cl.exe. This produces full paths in output.
这样可以解决我的问题...但是在我已经看到完整路径的情况下，不会设置该选项，因此这里还有其他作用.
so that solves my problem...but that option isn't set in the case where I already see full paths, so there's something else at play here.
