Mac: msdf-atlas-gen is failing but doesnt give more info

[rotter]

I would suggest that when calling the external programs such as msdf-atlas-gen, to always display the full command line so we can debug in case of failure.

Im getting repeatedly the same message and I have no idea what file is failing, or the reason for failure. If I had the full command I could try to tweak/debug it. I noticed there is a commented line that for that ( line 247: System.out.println(cmd); )

Using fontHandle: OpenSans-Regular.ttf Absolute
cmap is OpenSans-Regular.ttf.cmap.txt Absolute
Generating structured JSON font and PNG using msdf-atlas-gen...

Sizes go down all the way to 10 repeating this same error/warning messages, then exits the program

Yeah, I had no way to test on Mac, so thank you for being the first tester on the OS! It looks like you fixed it in #3 , also?

Yes, but maybe a "--verbose" arg would be nice to enable all the logs and see any issues. For example on Mac there's lots of permission issues that future users will run into (and some may not know how to solve). For example you need to make those 2 binaries runnable (chmod +x), and also the first time you run them Mac will block them from running and you have to open the System Settings to allow it to run, then start again the project... certainly a more verbose log would help the users on these cases

Ugh yeah, I don't have a Mac to test on, nor any way to notarize the binaries, so I don't really know what to document there. I know there are issues related to browsers blocking downloaded executables from running, which curl avoids, but I don't know which executables need it...
