multiple rules generate esp-idf/main/lib/usrsctp/usrsctplib/libusrsctp.a

[TVD-Contributor]

I've checked out & patched as described in the readme, but get a build issue:

ninja: error: build.ninja:18619: multiple rules generate esp-idf/main/lib/usrsctp/usrsctplib/libusrsctp.a [-w dupbuild=err]

I've repeated the git clone & patch operations several times with the same result. I believe my ESP-IDF environment & tools is 4.3.2, though I reverted the esp-idf code to 4.3.1 so I could patch mbedtls. I'm building on Windows 10.

@ycyang1229 Hoping you might be able to look at this, I'm not very familiar with CMake/Ninja etc.

[dhornacek-spindance]

@TVD-Contributor wanted to check in and see if you found any solution in the meantime? I am running into the same issue for the same file. Cannot pinpoint where this duplication is occurring.

Update (5/4) - @TVD-Contributor we were able to get past this, and successfully configure, by pointing master back to commit 05cd8cd0a0ad2d660bf0d499c9cc6810983a2a8f which is just before usrsctp was added. I think this module only affects the data channeling feature. Obviously not a fix by any means but a workaround in the meantime in case anyone else runs into this.

@TVD-Contributor wanted to check in and see if you found any solution in the meantime? I am running into the same issue for the same file. Cannot pinpoint where this duplication is occurring.

Glad you found a work-around. My solution was to comment out this line in main\lib\usrsctp\usrsctplib\CMakeLists.txt (line 203 in my copy):

# set_target_properties(usrsctp-static PROPERTIES OUTPUT_NAME "usrsctp")

I also needed to add an audio track in order for the demo to work in Chrome (I think it was?) by uncommenting these lines in AppCommon.c (lines 649-660). Without it, it'll be missing from the ESP32's SDP and Chrome will reject the negotiation, as Chrome demands all of its media tracks are at least acknowledged. It can be simply set to "inactive" but it must be present.

CHK_STATUS((addSupportedCodec(pStreamingSession->pPeerConnection, codec)));
pAudioTrack->kind = MEDIA_STREAM_TRACK_KIND_AUDIO;
pAudioTrack->codec = codec;
//audioRtpTransceiverInit.direction = RTC_RTP_TRANSCEIVER_DIRECTION_SENDONLY;
audioRtpTransceiverInit.direction = RTC_RTP_TRANSCEIVER_DIRECTION_INACTIVE;
STRCPY(pAudioTrack->streamId, APP_AUDIO_TRACK_STREAM_ID);

[dhornacek-spindance]

@TVD-Contributor Thanks for the response! Appreciate the extra info about the audio. I was able to configure, but am currently running into compile errors when trying to build. I am curious if you ran into these also? It's mostly error: redefinition of typedef 'UINT32' with different type for multiple files. I am also running into a lot of inline function ... declared but never defined. Wanted to check just in case.

[TVD-Contributor]

@dhornacek-spindance I don't recall those compiler errors when compiling with ESP-IDF 4.3.1 environment (and make sure you follow the full steps to apply all the patches supplied in the AWS-KVS sample). So that's Xtensa esp-2021r1-8.4.0 - obviously I'm targeting ESP32 (not ESP32S2 etc.). I'm using VSCode.

I haven't tried compiling for IDF 4.4 yet.

[TVD-Contributor]

@dhornacek-spindance Oh, I'm also on Windows, perhaps the redefinitions are a consequence of WIN32 being defined, or not?

[ayazalavi]

I am having same build error. I am using idf v4.4.1. Can anyone guide to fix this problem? Above fixes are not working either.

Will this let me do WebRTC call with peer?

[ayazalavi]

any one having this problem can turn off data channel by editing line 2 in CMakeLists.txt to:

option(ENABLE_DATA_CHANNEL "enable the data channel" OFF)

[ycyang1229]

Please try the new commits and it should be fixed.
