Re: building the JDK on Windows using Cygwin

Chen! Good news: your fix works. Here's more on what I did. 1. I ran fsutil 8dot3name set 0 2. I rebooted into Safe Mode 3. I ran fsutil file setShortName in Program Files (x86); "Windows Kits" became WINKIT~1 4. I exited safe mode 5. I ran fsutil file setShortName in Program Files; "Microsoft Vi

Re: building the JDK on Windows using Cygwin

Hi SWinxy, For not finding JDK, I recommend you set the %JAVA_HOME% environment variable to your latest Java installation. For VS, configure looks for the path and tries to fixpath, so you should be good mostly if you set the short names (just need no spaces) for "Windows Kits" and "Microsoft Visua

Re: building the JDK on Windows using Cygwin

[Chen] "try uncheck and recheck the box" How will that help? Following your suggestion, I ran the Installer, then I unchecked the "Desktop Components for C++" box and it says -6.81Gb That shows it was installed. Now I check the box again, and it says 0 Gb. Now the Close button is enabled. So No ac

Re: building the JDK on Windows using Cygwin

When I installed VS, I ensured that Desktop Development with C++ was checked. I ran the installer again, and it shows as checked and since the "Modify" button is not enabled, but "Close" is enabled, it means that it is already installed. It is the only box checked. On Fri, Jul 5, 2024 at 11:50 AM

Re: building the JDK on Windows using Cygwin

Hi Anil, I had encountered the same problem before. Can you try install VS's desktop development with c++ with its default selection? Last time I unchecked some boxes and failed like you did. I don't think other big components are required for jdk. On Fri, Jul 5, 2024, 11:46 AM Anil <1dropafl...@g

Re: building the JDK on Windows using Cygwin

Over the past few days, I have tried a lot of things. I reinstalled Cygwin. I used Git for Windows instead of Cygwin Git. I uninstalled and reinstalled Visual Studio and in different locations, but it didn't fix it. I added my user name to the Administrator Group account because one post said that

Hi, If you want to know a Windows path to the Cygwin directory you're in, you can use the following command: $ cygpath -w `pwd` C:\cygwin64\home\anil If you want to know a Cygwin path without spaces for a Windows directory, you can use the following: $ cygpath `cygpath -d 'C:\Program Files\Micros

Hi Anil, I can confirm that building on Windows 11 + cygwin + VS 2022 Community installed with default settings and in the default location works just fine without any extra command line parameters. The only parameter you need is --with-boot-jdk, and even that can be omitted if you have the right J

Make sure all visual studio and related processes running in that directory are terminated. If you have trouble you might restart windows in safe mode. Also for configure/make, never pass paths with spaces, always use short name to avoid space, use /cygdrive/c/..., and never pass backslashes. That

Usually Microsoft Visual Studio c compiler (as installed by Visual Studio installer) already has short names set. It seems the short name has to be 8 characters in length and you can't set it when some process is running in that directory. You can check the short path in Windows cmd's "dir /x" comm
