Experiencing an issue in WolfSSH version 1.4.13 when used with FreeRTOS and lwIP, and combined with the most recent version of wolfSSL. The compiler is indicating an "undefined identifier 'heap'" error within the internal.c file.

Error Details:

  • Error Message: #20 identifier "heap" is undefined

  • Location in Code: internal.c Line 1052 (GitHub Link)

  • WolfSSH Version: v1.4.13

  • Additional Environment: FreeRTOS + lwIP, wolfSSL latest version

Questions:

  • Has anyone experienced a similar issue with the "heap" identifier in WolfSSH v1.4.13? If so, how was it resolved?

  • Could this error be related to specific configurations or dependencies required for integrating WolfSSH with FreeRTOS and lwIP (e.g., WolfSSL/WolfCrypt)?

  • Are there any particular user settings that should be verified or adjusted to resolve this issue?

  • Would upgrading or downgrading WolfSSH potentially solve this problem, or are there known workarounds for this version?
