Hmm. Does fl2_peerconnection link on its own?
The implementation of webrtc::CreateIceCandidate is in jsepicecandidate.cc, which is in the pc:peerconnection target. You should get that one indirectly through your dependency on pc:libjingle_peerconnection. I guess you can try adding pc:peerconnection to the deps list and hack the visibility to make it work, if necessary, but I don't think it should make a difference.

Hi Patrik Höglund
Yes, it does. I have replaced pc:libjingle_peerconnection with pc:peerconnection (rebuild).
The result seems correct, but the error message still appears....

Ok, looks like adding pc:peerconnection fixed the problem. The two remaining errors are in the Poco:: and SIOClient:: namespaces, which is outside of the WebRTC code, so you have to fix those by yourself.
As for how the problem got fixed, it sounds like you're confused. Consider the following example:
executable("meh") {
sources = ["meh.cc"]
deps = [
"../pc:libjingle_peerconnection",
"../api:libjingle_peerconnection_api",
"../system_wrappers:field_trial_default",
"../system_wrappers:metrics_default",
"../system_wrappers:runtime_enabled_features_default",
]
if (!build_with_chromium && is_clang) {
# Suppress warnings from the Chromium Clang plugin (bugs.webrtc.org/163).
configs -= [ "//build/config/clang:find_bad_constructs" ]
}
}
meh.cc:
#include "api/jsepicecandidate.h"
int main(int argc, char** argv) {
webrtc::CreateIceCandidate("!!", 17, "18", nullptr);
return 0;
}
If I remove "../pc:libjingle_peerconnection" from deps, I get the expected link error:
python "../../build/toolchain/gcc_link_wrapper.py" --output="./meh" -- ../../third_party/llvm-build/Release+Asserts/bin/clang++ -fPIC -Wl,-z,noexecstack -Wl,-z,now -Wl,-z,relro -Wl,-z,defs -Wl,--no-as-needed -lpthread -Wl,--as-needed -fuse-ld=lld -Wl,--icf=all -m64 -Werror -Wl,--gdb-index -Wl,--fatal-warnings -nostdlib++ --sysroot=../../build/linux/debian_sid_amd64-sysroot -L../../build/linux/debian_sid_amd64-sysroot/usr/local/lib/x86_64-linux-gnu -Wl,-rpath-link=../../build/linux/debian_sid_amd64-sysroot/usr/local/lib/x86_64-linux-gnu -L../../build/linux/debian_sid_amd64-sysroot/lib/x86_64-linux-gnu -Wl,-rpath-link=../../build/linux/debian_sid_amd64-sysroot/lib/x86_64-linux-gnu -L../../build/linux/debian_sid_amd64-sysroot/usr/lib/x86_64-linux-gnu -Wl,-rpath-link=../../build/linux/debian_sid_amd64-sysroot/usr/lib/x86_64-linux-gnu -Wl,-rpath-link=. -Wl,--disable-new-dtags -o "./meh" -Wl,--start-group @"./meh.rsp" -Wl,--end-group -ldl -lpthread -lrt -lXext -lX11 -lXcomposite -lXrender

If I add "../pc:libjingle_peerconnection" back, it links. If I replace it with "../pc:peerconnection", it also links. This is what I would have expected, since
rtc_source_set("libjingle_peerconnection") { visibility = [ "*" ] deps = [ ":create_pc_factory", ":peerconnection", "../api:libjingle_peerconnection_api", ] }
transitively includes pc:peerconnection for you. This correctly puts pc:peerconnection to the right of CCServiceUnit in the linker order, and the linker will resolve CreateIceCandidate when it gets to pc:peerconnection.
Note that gn enforces that you directly depend on targets you #include from, but you don't have to directly depend on targets that has a .cc with a symbol you need. Transitive deps are fine (perhaps even encouraged) there. Either way, it's almost always the case that .h and .cc files live together in the WebRTC repo, but there some exceptions where api/ targets declare a bunch of things in .h files and it's up to you to choose your implementation. api:libjingle_peerconnection_api and pc:peerconnection have this relationship, for instance.

Thank you.
Following your suggestions. I solved it, gn args add deps = [ "//webrtc/api:libjingle_peerconnection_api", "//webrtc/pc:libjingle_peerconnection", ].
I have some questions I would like to ask.
1. How to replace "SignalFrameCaptured" with "OnFrame" in my code?
2. How to replace "cricket::CapturedFrame" with "webrtc::VideoFrame" in my code?
Here is my code.
bool QueueVideoCapturer::CaptureCustomFrame(const shared_ptr<CaptureFrame>& cf) {
if (!running_) {
return false;
}
int width = GetCaptureFormat()->width;
int height = GetCaptureFormat()->height;
int fourcc = GetCaptureFormat()->fourcc;
if(cf) {
if(start_rtc_timestamp==-1) {
start_rtc_timestamp = cf->rtc_timestamp;
}
// Currently, |fourcc| is always I420 or ARGB.
// TODO(fbarchard): Extend SizeOf to take fourcc.
uint32_t size = 0u;
if (fourcc == cricket::FOURCC_ARGB) {
size = width * 4 * height;
} else if (fourcc == cricket::FOURCC_I420) {
size = FrameSizeOf(width, height);
} else {
return false; // Unsupported FOURCC.
}
if (size == 0u) {
return false; // Width and/or Height were zero.
}
#if 0
cricket::CapturedFrame frame; <-- 1
frame.width = cf->width;
frame.height = cf->height;
frame.fourcc = fourcc;
frame.data_size = cf->frame_size;
frame.time_stamp = cf->rtc_timestamp * 1000;//webrtc::TickTime::MicrosecondTimestamp()*1000;
frame.data = cf->frame.get_data();
SignalFrameCaptured(this, &frame); <-- 2
#else
rtc::scoped_refptr<webrtc::I420Buffer> buffer(webrtc::I420Buffer::Create(cf->width, cf->height));
buffer->InitializeData();
int crop_x;
int crop_y;
int crop_width;
int crop_height;
const uint8_t* y_plane = (const uint8_t*)(cf->frame.get_data());
const uint8_t* uv_plane = y_plane + width * height;
int uv_width = (width + 1) / 2;
crop_x &= ~1;
crop_y &= ~1;
libyuv::NV12ToI420Rotate(
y_plane + width * crop_y + crop_x, width,
uv_plane + uv_width * crop_y + crop_x, width, buffer->MutableDataY(),
buffer->StrideY(),
// Swap U and V, since we have NV21, not NV12.
buffer->MutableDataV(), buffer->StrideV(), buffer->MutableDataU(),
buffer->StrideU(), crop_width, crop_height,
static_cast<libyuv::RotationMode>(0));
const webrtc::VideoFrame frame(buffer, webrtc::kVideoRotation_0, cf->rtc_timestamp * 1000);
this->OnFrame(frame, cf->width, cf->height);
#endif
}
return true;
}
