Question

我正在尝试使用MSVC链接器的ICU代码。但是，启动Cygwin将/ usr / local / bin和/ usr / bin放在路径前面，导致link.exe始终调用Cygwin版本，而不是MSVC版本。如何解决此配置问题？目前，我启动VS命令提示符，然后启动cygwin.bat。

/ usr / local / bin：/ usr / bin：/ cygdrive / c / Program Files（x86）/ Microsoft F＃/ v4.0：/ cygdr ive / c / Program Files（x86）/ Microsoft Visual Studio 10.0 / VSTSDB / Deploy：/ cygdrive / c / Program Files（x86）/ Microsoft Visual Studio 10.0 / Common7 / IDE：/ cygdrive / c / Progra m Files（x86）/ Microsoft Visual Studio 10.0 / VC / BIN：/ cygdrive / c / Program Files（x86）/ Microsoft Visual Studio 10.0 / Common7 / Tools：/cygdrive/c/Windows/Microsoft.NET/F ramework / v4.0.30319：/cygdrive/c/Windows/Microsoft.NET/Framework/v3.5：/ cygdrive / c / Program Files（x86）/ Microsoft Visual Studio 10.0 / VC / VCPackages：/ cygdrive / c / Prog ram文件（x86）/ HTML帮助研讨会：/ cygdrive / c / Program Files（x86）/ Microsoft Vis ual Studio 10.0 /团队工具/性能工具：/ cygdrive / c / Program Files（x86）/ Mic rosoft SDKs / Windows / v7.0A / bin / NETFX 4.0工具：/ cygdrive / c / Program 文件（x86）/ Mi crosoft SDKs / Windows / v7.0A / bin：/ cygdrive / c / Program 文件/公共文件/ Microsoft共享/ Windows 住：/ cygdrive / C /窗/ SYSTEM32：/ cygdrive / C / Windows的：/ cygdrive / C /Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygd rive / c / Program Files（x86）/ Microsoft SQL Server / 100 / Tools / Binn：/ cygdrive / c / Progr am Files / Microsoft SQL Server / 100 / Tools / Binn：/ cygdrive / c / Program Files / Microsoft SQL Server / 100 / DTS / Binn：/ cygdrive / c / Program Files（x86）/ Microsoft ASP.NET / ASP.N ET网页/ v1.0：/ cygdrive / c / Program Files / TortoiseHg：/ cygdrive / c / Program Files （86）/GtkSharp/2.12/bin:/cygdrive/c/Users/tim/AppData/Roaming/npm:/cygdrive/c/P rogram Files（x86）/ nodejs：/ cygdrive / c / Program Files（x86）/ Common 文件/ Intuit / QB POSSDKRuntime：/ cygdrive / c / Program Files（x86）/ Git / cmd

ICU告诉我

确保PATH的顺序是MSVC，Cygwin，然后是其他顺序路径。 configure脚本需要Cygwin中的某些工具（例如grep）。

更新。我的cygwin.bat看起来像这样：

@echo off

C：chdir C：\ cygwin \ bin

bash --login -i

不是很有帮助。

对于Cygwin的默认安装，PATH设置为/ etc / profile。您可以修改PATH，以便附加/ usr / local / bin：/ usr / bin而不是前缀。

# PATH="/usr/local/bin:/usr/bin:${PATH}"
PATH="${PATH}:/usr/local/bin:/usr/bin/"

Answer 2

我认为更简洁的方法是使用在Cygwin的ORIGINAL_PATH中创建的/etc/profile变量。修改您的.bashrc文件以使用ORIGINAL_PATH，然后添加/usr/local/bin和/usr/bin，而不是修改此文件。

.bashrc：

export PATH=$ORIGINAL_PATH:/usr/local/bin:/usr/bin

然后您不必修改Cygwin安装文件。

/ usr / local / bin：/ usr / bin：到$ PATH的末尾而不是在顶部
