Cannot connect to dll

[macadamia]

I managed to build vlab-release-arm64-v5.1

But get the following returned:

lpfg -b lsystem.l view.v
clang++ -std=gnu++11 -O3 -arch arm64 -c lsys.ii -Wno-return-type-c-linkage
clang++ -std=gnu++11 -O3 -arch arm64 -dynamiclib -o lsys.so lsys.o
Cannot connect to dll

file lsys.so
lsys.so: Mach-O 64-bit dynamically linked shared library arm64

I'm used the Homebrew version of qt

I tried the same command on two different computers and it worked. I did not get the message "Cannot connect to dll". Can you share the lsystem.l and view.v files?

01-quadratic-Koch lpfg lsystem.l anim.a view.v color.map
qt.qpa.fonts: Populating font family aliases took 104 ms. Replace uses of missing font family "Times" with one that exists to avoid this cost.

corrected rotation: command not found.
If rotations are different than in previous versions of lpfg, include the line
corrected rotation: off
in the view file. To eliminate this warning message, put the line
corrected rotation: on
in the view file. See the entry on corrected rotation: in the documentation,
section 3.2: "Draw/view parameters file" for an explanation.

Thanks for sending the zip. The model runs fine for me with and without "-b", and I do not get the "dll" message. What version of macOS and SDK are you compiling with? Perhaps I can send you a bundled version of vlab to test.

[macadamia]

macOS 15.5
Xcode 16.3

What do you mean by SDK in this case?

[mikcieslak]

I have not tried compiling on macOS 15.5. Maybe that is where the problem is coming from. I will send you a link to download a version complied on macOS 14.7.6, which is what I've been testing on.

To get the SDK version, run xcrun --sdk macosx --show-sdk-path, it should be macOS15.5.sdk.
