I receive the following error when loading mod_whisper on a brandnew Freeswitch in Debian 12:

Hey again 😅

I think I got the build setup working (see #12). When running make I get the following error (FreeSwitch 1.10, Debian 12):

making all mod_whisper
make[4]: Entering directory '/usr/src/freeswitch/src/mod/asr_tts/mod_whisper'

What would be a reasonable initial value of n?

Setting int n = 1; would work in case the context is never empty when context->started == WS_STATE_STARTED. 🤷‍♂️

From this example it seems that n represents the payload size (length of context->result_text?).

For FreeSwitch 1.10 there is no top-level modules.conf file.

I looked for modules.conf by searching the FreeSwitch for ASR/TTS modules that I assume to be included in a similar manner: https://github.com/search?q=repo%3Asignalwire%2Ffreeswitch%20asr_tts&type=code
There, 2 files look like they could be the right ones:

1. build/modules.conf.most
2. build/modules.conf.in

So which one should asr_tts/mod_whisper be added to? Or do I have to create modules.conf in the FreeSwitch source root?

Thanks in advance 🙏

PS: I am new to FreeSwitch and this is my 1st module installation. 😅

hi,
I had porblem when i load this module on freeswitch, which return the error like this

2023-09-04 18:02:41.525076 [CRIT] switch_loadable_module.c:1785 Error Loading module /usr/local/freeswitch/lib/freeswitch/mod/mod_whisper.so
**/usr/local/freeswitch/lib/freeswitch/mod/mod_whisper.so: undefined symbol: lws_wsi_user**

And i had install ths libwebsockets, and the version of libwebsockets is v4.3.2

ldconfig -p |grep libwebsockets

return:

	libwebsockets.so.19 (libc6,x86-64) => /usr/local/lib/libwebsockets.so.19
	libwebsockets.so.13 (libc6,x86-64) => /usr/lib64/libwebsockets.so.13
	libwebsockets.so (libc6,x86-64) => /usr/local/lib/libwebsockets.so

Thanks in advance.

When I recompile on freeswitch, it said

make: Nothing to be done for 'all'.
for mod_whisper

Is that normal?

when i try to make call from the free switch I get these errors in the FreeSWITCH logs.
