PDF compilation on a RAM-limited machine (Windows with 8GB)

[ronaldtse]

On a user's desktop machine, it only has 8GB RAM and is running Windows 11.

The default 4GB seems to be unable to compile the Document 01 PDF.

We are clearly not able to use 8GB because of this failure:

Error: Could not create the Java Virtual Machine.
A fatal exception has occurred.

@Intelligent2013 I wonder if we can further lower the memory needs of PDF compilation, by using Document 01 as an example?

[Intelligent2013]

Looks like something wrong in the JVM starting, but not PDF compilation.

Questions:

1. how do you run the PDF compilation? Please provide the command line.
2. please run java -version

hello @Intelligent2013

i dont know the command line for PDF compilation; please ask @ronaldtse for that

normally we use:
bundle exec metanorma sources/001-v4/document.adoc
or
bundle exec metanorma site generate --agree-to-terms

the java version information, is shown here

i think the clean machine may have been win10 not win11; @AIS-RyoMukai please confirm the OS on the "clean machine" we tested today. thank you.

@ReesePlews thank you for the additional information. The java -version output doesn't contain the 64-bit. It means that the 32-bit version of JVM installed. The maximum 32-bit JVM heap size limited to 1.6-1.8Gb (https://www.oracle.com/java/technologies/hotspotfaq.html#:~:text=The%20maximum%20theoretical%20heap%20limit,1.4G%20to%201.6G.). To solve the issue, please upgrade the JVM to the 64-bit version (and use the JVM update 241 or higher (8u241)).

For instance, java -version on my machine (Win10 64-bit):

java version "1.8.0_333"
Java(TM) SE Runtime Environment (build 1.8.0_333-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.333-b02, mixed mode)

thank you @Intelligent2013 ; on my windows machine (Win 10 64-bit) i have this version of Java installed;

PS C:\Users\admin> java -version
openjdk version "17.0.13" 2024-10-15
OpenJDK Runtime Environment Temurin-17.0.13+11 (build 17.0.13+11)
OpenJDK 64-Bit Server VM Temurin-17.0.13+11 (build 17.0.13+11, mixed mode, sharing)

i have had no problems running metanorma with the plateau documents on my local install
