This is because hiccup relies on eval for compiling input. So hiccup only works when it's used in a "static" way.
I am getting the following errors:
./aws-api-s3

Not sure if anyone have idea about how to make this work.
I am guessing that it may have something to do with adding the following config as part of native-image generation.
My env:
graalvm-ce-java11-20.3.0
Clojure 1.10.1-rc2
Java 1.11.0
With the new GraalVM 20.1 release would be nice to have a way to check how each major release compares with the older ones.
WDYT?

After applying ring-clojure/ring#381 locally, I was able to run this. Once that is merged, we should update the dependencies and I think ring-jetty will run.
I just tried out asami locally:
https://github.com/threatgrid/asami
$ ./asami
(["Explorers"] ["Demolition Man"] ["Johnny Mnemonic"] ["Toy Story"])
Worked great, memory consumption during compilation is far more reasonable than datascript.
Hopefully once it gets durable storage it keeps working well like this.
depstar has been deprecated and archived for six month now; I'm encouraging everyone to switch to tools.build. My build-clj wrapper makes it easier to switch.
Please update Readme to indicate the final size of the executable, including the sizes of all dependencies.
If one were to create a demo using this tool, how much does the end-user need to download and install assuming no dependencies are pre-installed.
Currently, you can't build a native-image that uses spec: oracle/graal#1681. It could be good to add a small test project demonstrating that to test against.
Hi there,
First of all many thanks for this repo - it contains some super valuable information! I just wanted to say that I was recently trying to create a native-image for cryptohash-clj, and it turns out that the problem was statically initialised instances of SecureRandom. You see, the library has a dynamic Var initialised with an instance of SecureRandom, and no matter what I did, I wasn't able to generate a working image (I tried literally everything). I wrapped that instance in a delay (see here), and now the native-image is working as expected.
I just thought you (or someone else) might find that information useful.
Kind regards
Idk where else to document this in a public manner.
Hickory, as well as most other projects labeling themselves as html parsers don't play nicely with graalvm.
This is because jsoup wants to be initialized at runtime and clojure libs at build time.
The project where I tried for days to get it to play with graal: bbyt
I've compiled jep, which is a jni based embedded python runtime https://github.com/zcaudate/sample-jep-graal but am getting a weird output.
Have you seen something similar to this before?
Following #51 (comment)
I think it could be a very fun thing for me to work on :-)
I've been experimenting with drewr/postal to be able to send e-mails from a native-image.
So far it fails for me with:
#error {
:cause "smtps"
:via
[{:type javax.mail.NoSuchProviderException
:message "smtps"
:at [javax.mail.Session getService "Session.java" 811]}]
I've tried adding com.sun.mail.smtp.SMTPTransport to the reflection config, but this didn't help.
--initialize-at-build-time without arguments has been deprecated when not using --diagnostics-mode. With GraalVM 22.0.0 --initialize-at-build-time will only work with --diagnostics-mode for debugging purposes.
The reason for deprecation is that --initalize-at-build-time does not compose, i.e., a single library can make assumptions that the whole classpath can be safely initialized at build time; that assumption is often incorrect.Hello,
Following a bug fix in http-kit, to compile the client with version 2.5.2 the following initialization flag is required:
--initialize-at-run-time=org.httpkit.client.ClientSslEngineFactory\$SSLHolder
Will PR this soon
Cheers :)
