在Visual Studio 2015中时，Win flex-bison始终返回1，但在手动运行时可以工作

如何解决在Visual Studio 2015中时，Win flex-bison始终返回1，但在手动运行时可以工作

我安装了与VS集成的Win flex-bison。这允许项目包含.l和.y文件。 问题是当我尝试使用VS进行编译时

1>------ Build started: Project: pasms64,Configuration: Release Win32 ------
1>  Process "pasm64.l" flex file
1>C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Addins\win_flex_bison-latest\custom_build_rules\win_flex_bison_custom_build.targets(129,5): error MSB3721: The command "call win_flex.exe --outfile="pasm64.flex.c" --wincompat --noline  "pasm64.l"" exited with code 1.
========== Build: 0 succeeded,1 failed,0 up-to-date,0 skipped ==========

当我从命令行手动运行时，它运行正常。

C:\Users\jaret\OneDrive\Desktop\Pet\Pasm\pasm64>cd C:\Users\jaret\OneDrive\Desktop\Pet\Pasm\pasm64

C:\Users\jaret\OneDrive\Desktop\Pet\Pasm\pasm64>call win_flex.exe --outfile="pasm64.flex.c" --wincompat --noline  "pasm64.l"

C:\Users\jaret\OneDrive\Desktop\Pet\Pasm\pasm64>

VS的道具文件

我的问题是为什么从props文件运行时这不起作用。 我有什么办法可以解决这个问题。

解决方法

问题是路径问题。我通过使用自定义构建步骤解决了这一问题。当我为文件使用完整路径时，它可以按预期工作。没有什么比无声的失败更糟糕了，
