Error running on macOS

[xgp]

I'm not sure if Valum is tested on macOS, so that may be the core issue here. Compilation works fine, but I'm seeing the following when I try to run:

$ app

** (process:57895): CRITICAL **: vsgi-server-module.vala:67: dlopen(libvsgi-http.so, 9): image not found

** (process:57895): CRITICAL **: vsgi_server_run: assertion 'self != NULL' failed

I'm using Vala 0.38.7.

Any suggestions?

[xgp]

Looks like dlopen is trying to load the .so rather than the .dylib. I don't know where/how that is specified, but it seems as if it may be the culprit.

[arteymix]

It's defined here: https://github.com/valum-framework/vsgi/blob/master/src/vsgi-server-module.vala#L59

It's using GModule under the hood, so I'd expect it to just work.

[arteymix]

It's an issue with Meson: mesonbuild/meson#3053

If they accept to change shared_module behaviour, it will be an easy fix, otherwise I'd have to put some conditionals in the build.

[arteymix]

Could you test https://github.com/valum-framework/valum/tree/stable?

You can set revision=stable in valum.wrap.

[xgp]

Switched valum.wrap to revision=stable and did a fresh build, but I got the same result/error.

[arteymix]

Have you done the following?

• wipe build
• put revision=stable in subprojects/valum.wrap
• fresh build

I don't own a Mac, so I cannot be of much help..

[xgp]

Yes. I did it from a clean clone just in case. Same result.

Also, running the tests in that branch of valum fails in the tests that attempt load any modules:

I've also seen this happen (in person) but couldn't investigate further as it wasn't my mac

[arteymix]

Could any of you run the tests with strace and send me a dump?

There's some work upstream to include more sensible prefix/suffix for loadable objects: in GModule https://bugzilla.gnome.org/show_bug.cgi?id=671212#c5

[xgp]

Ran with dtruss on mac. Output attached. Let me know if you want it run in another way.
dtruss.log

[arteymix]

I'm already aware of the bug now! I pushed a fix here: valum-framework/valum@6a46be9 if you want to test it.

[xgp]

Close, but have to get rid of the trailing '.so':

** (process:86549): CRITICAL **: vsgi-server-module.vala:71: dlopen(libvsgi-http.dylib.so, 9): image not found

** (process:86549): CRITICAL **: vsgi_server_run: assertion 'self != NULL' failed

[arteymix]

It should work now!

[xgp]

It looks like the dylib that gets created is not of the name that is expected:

[garth@garths-mbp:build (wip/macos-module-dylib)]$ ls src/vsgi/
libvsgi-0.3.dylib  servers/           vsgi-0.3.vapi      vsgi-0.3@sha/      vsgi.h
[garth@garths-mbp:build (wip/macos-module-dylib)]$ ls src/valum/
libvalum-0.3.dylib  valum-0.3.vapi      valum-0.3@sha/      valum.h

If I create some symlinks for -fastcgi, -http and -mock, it finds the libs, but then I get the following errors:

Looks like there is no server_init?
