Hi Neil

Is there any reason that there's no "." in the output of your ls command, i.e. why it's libnanovgdylib rather than libnanovg.dylib ?

Nope it is present. For some reason the email removed it. If you look on the web version of github issues it is present. And I just checked again on my system and it is present.

Ok, sorry about that - I only looked in my email client, not on GH.

A few questions:

Are you working from HEAD, or 0.6.0?

Which version of OSX are you on?

Does the nanovg library load up ok if you're not aot-compiling?

Cheers, Ben

Error: could not find xtmnanovg dynamic library
benswift commented 8 years ago

Sorry about the delay, I've been on holidays.

I've just tried it on my machine (same OS, similar box) and it worked.

The line

Error: could not find xtmnanovg dynamic library

indicates that it's the aot-compiled dylib (i.e. xtmnanovg rather than libnanovg) that's the problem. There are a few potential causes:

To diagnose further, you can use an optional second argument to sys:open-dylib, which (if truthy) will print the error messages from dlopen if it fails.

So, what is the output from

(sys:open-dylib "libnanovg.dylib" #t)

There is no error, (sys:open-dylib "libnanovg.dylib" #t) loads fine. Please ignore the previous version of this message I misspelled the lib name.

(sys:load "libs/external/nanovg.xtm") fails with 

Error: could not find libnanovg dynamic library

I'm not using homebrew. nanovg is installed using a git pull from https://github.com/extemporelang/nanovg.git then make then make install.

benswift commented 8 years ago

I think at this point the best thing to try the aot-compiled "header" file for nanovg, which will be in libs/aot-cache/nanovg.xtm. If you go through it line-by-line (maybe skip/comment out the (set! *impc:compiler:message:level* 'low) line so you can see all the compiler output) you should be able to see exactly what's going wrong.

It appears that commit 4354cf0e5cb842be6006e05546223c8c0a1a5292 fixed the issue for nanovg. Thank you.

However a new issue arose with libassimp not being found from MacPorts. MacPorts stuff is in /opt/local/lib/. The following diff is verified to fix the problem of locating libs installed from the MacPorts default location.
