soprano @2.9.4_5+universal: Undefined symbols for architecture (fill in non-host architecture): _JNI_CreateJavaVM

[ryandesign (Ryan Carsten Schmidt)]

Undefined symbols for architecture i386:
  "_JNI_CreateJavaVM", referenced from:
      JNIWrapper::instance() in jniwrapper.cpp.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #49902.

[mf2k (Frank Schima)]

See #57827

[chrstphrchvz (Christopher Chavez)]

soprano has since been updated to 2.9.4_4. Is this ticket still relevant (particularly given the improvements made in [314102b37f/macports-ports]), or can it be closed?

[ryandesign (Ryan Carsten Schmidt)]

The problem still exists, as originally reported.

So this port can't build universal on an M1 Mac (or perhaps on any Mac) because the JVM isn't universal.

I am not sure if we might hack together a universal java-19 installation for M1 Macs -- it might be possible.

Edit: I did this for openjdk-18, but it was unstable. ​https://github.com/kencu/macports-ports/commits/openjdk18universal

But you can install soprano +universal if you disable all the JAVA stuff. To do that, I just forced it all off everywhere, like this:

if soprano is really disabled badly without JAVA support, then some other plan will be needed.

In 0af732b43cb96a154a45f391d9d9f93b004bcc2f/macports-ports (master):

soprano: disable java backend

the JavaVM requirement is a problem, as there is no current universal JavaVM for arm64/x86_64
and the kde ports can't build as arm64. So they would need an x86_64 JavaVM installed if there
is one. Any JavaVM the user has installed on an arm Mac is unlikely to be Intel arch.
just disable the java backend to allow the kde4 ports to build.
