LINK : fatal error LNK1181: cannot open input file 'stdc++.lib' on Windows

[jvalkeal]

Describe the issue

JRT causing linking failure on windows. Having -H:+AllowJRTFileSystem adds stdc++ in

graal/substratevm/src/com.oracle.svm.hosted/src/com/oracle/svm/hosted/jdk/JRTFeature.java

Line 39 in c4de3ae

beforeAnalysisAccess.getNativeLibraries().addDynamicNonJniLibrary("stdc++");

which then throws error during a build:

2023-01-30T18:28:51.6624600Z LINK : fatal error LNK1181: cannot open input file 'stdc++.lib'

Steps to reproduce the issue

1. On windows use flag -H:+AllowJRTFileSystem

Describe GraalVM and your environment:

• GraalVM version CE 22.3.0
• JDK major version: 17
• OS: Microsoft Windows Server 2022 on github hosted runner

More details
Similar to #1876 which was fixed by not using stdc++ if not a posix system.

Also JNIRegistrationAwt looks to have similar stdc++ issue.

Hi, Thank you for reaching out about this issue, I tried adding the flag to the native-image build command of a simple HelloWorld on Win10 and managed to build it successfully, do I need something more sophisticated than HelloWorld to reproducer? in that case please share a reproducer.

[jvalkeal]

Let me try to create a sample where it fails.

[jvalkeal]

@oubidar-Abderrahim Here's a sample project https://github.com/jvalkeal/stdcfail which shows failure with GH actions.

[oubidar-Abderrahim]

Tracked internally on GR 44527

[wirthi]

The Flag -H:+AllowJRTFileSystem is only internal and should not be used. Is there a specific reason why you use it?

[jvalkeal]

@wirthi Yeah that is a good question and plot kinda thickens from here. Spring projects https://github.com/spring-projects-experimental/spring-cli and https://github.com/spring-projects-experimental/spring-boot-migrator are starting to experiment how to work in native and those use https://github.com/openrewrite/rewrite.

openrewrite uses jdk internals and that's when I noticed use of -H:+AllowJRTFileSystem makes things work in native.

Should probably cc @jkschneider if he is interested in this topic.

[jvalkeal]

If I use dev via graalvm/setup-graalvm this stdc++ lib is not passed to linker anymore. Looks like there's been some changes how linker is used but I couldn't really figure out what change(s) fixed it.

[wirthi]

Sorry, we have not working on that ticket internally. I'll check with the dev team if and what we can do on this.

[jvalkeal]

It very much looks like this was fixed in 744bafb. Side effect of #7454.
