Arduino Build Problem

[smithy2167]

I'm trying to build Heishamon for a generic ESP8266 using Arduino.
I'm getting a compilation error in ...HeishaMon\rules.cpp:76 saying 'MEMPOOL_ADDRESS' was not declared in this scope.
Looking at the files, there are two copies of rules.h (and rules.cpp), one in the Heishamon directory and one in the src/rules directory.
Both of the .h files are included in Heishamon.cpp. However, I think only the first is read - the one in the src/rules directory where the MEMPOOL_ADDRESS is defined would not be included because both start with #ifndef RULES_H statements.
I'm no expert on C or Arduino, so go easy on me. What am I doing wrong?

Look to GitHub workflow, and configure your Arduino IDE to meet all setting..

I've looked at my settings and can't find anything that seems incorrect.
For now, I've just loaded the pre-built binary and will leave the mods to another day.
Nice software BTW.

You definitely missed something, I don't remember right now, but i had same problem, but solved, and forgot.. later switched to vs code (platformio) for self builds..

ok, i find out again what is missing :) arduino ide 2, tools> MMU > select 16KB cache + 32KB IRAM +16KB 2nd cache (not shared)

it's what set in arcuino-cli flag, mmu=3216

in PlatformIO:
build_flags =
-D PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM32_SECHEAP_NOTSHARED

Which version of the ESP8266 library do you have installed? It won’t compile on 2.7.4 – it’s too old. You need version 3.1.2 or newer.

[robert-b]

no.
also with newer variants it does not compile.

[robert-b]

just declare:
unsigned char *mempool = NULL; //malloc in runtime

later in the code:
if (rule_options.event_cb == NULL) { //check if not initialized before
if (mempool == NULL) { //make sure we only malloc if not done before
#ifdef ESP32
mempool = (unsigned char *)ps_malloc(MEMPOOL_SIZE);
#elif defined(ESP8266)
mempool = (unsigned char *)os_malloc(MEMPOOL_SIZE);
#endif
if (mempool == NULL) {
logprintln_P(F("Mempool OOM"));
OUT_OF_MEMORY
}
}

no you are missing in copmile options. in arduino ide 2, tools> MMU > select 16KB cache + 32KB IRAM +16KB 2nd cache (not shared)
