Unable to compile under MacOS

[dernasherbrezon]

Hi,

I'm following the guide on how to compile and run:
https://nasa-jpl.github.io/ION-DTN/ION-Quick-Start-Guide/#build-ion-413-and-earlier-versions-without-actual-cipher-suite

Getting the following error:

Here is gcc version:

% gcc --version
Apple clang version 17.0.0 (clang-1700.4.4.1)

Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

It's likely your host does not have C18, so configure did not suppress the error. For 4.1.4-b.1, this will be changed to a pre-precessor macro. But if your host does not support C18 on macOS, it may run into other issues.

Try changing the definition of MAX_TOKEN to

#define MAX_TOKENS 99

Please update us if this is resolved. For now we are closing the issue.

Still failing, but at the different place:

bpv7/utils/sendfile.c:100:23: error: variable length array folded to constant array as an extension [-Werror,-Wgnu-folding-constant]
  100 |         char randInitializer[randomizer_size];
      |                              ^~~~~~~~~~~~~~~
1 error generated.

You're right C18 support might be missing.

Which version of ION is this one? Please remind me. Thanks!
