Just as a general heads-up...
Good to know and thanks for the heads up. I usually update my version after few weeks of releasing the newer one. I can not wait to see it in run and feedback from the users.

It seems like ThomasV is now actively compiling and signing electrum 4.x beta releases
https://download.electrum.org/4.0.0b1/
I'll keep my repo open, but it might be a good idear to get your builds directly from ThomasV's repo!

I honestly don't know that answer to that question. It could be that, or it could have simply been the more common "no route"-type issue. I had a few of those at various times (with lnd etc)... sometimes channels drop off and you can't get a payment route.
But yeah... a nonfunctional libsecp256k1-0.dll might cause issues.

Again, big thanks to mocacinno... he really does an awful lot for our community!
That is quite generous, thanks mocacinno.
Now, back to my stupid questions:
I didn't get a chance to play with lightning transactions yesterday with the newest source, but I'm wondering; would the libsecp255k1-0.dll file being 32bit vs 64 have had anything to do with my inability to send from one of my Electrum wallets to the other?
Now that I know I compiled the 64bit version of libsecp255k1-0.dll, I'm assuming that all of my previous compilations were 32bit.
In other news... mocacinno has been kind enough to provide a small file hosting repository for me... so, in future I'll be able to get 4.0.0 builds uploaded there instead of having to rely on free file hosting sites that have popups and ads and shit like that.
As you can see, aside from my current build, it also has my PGP signature (hcp_pgp.asc) and a .sig file for the build itself. You can also see the instructions in the README for how to retrieve my public key from keybase.io.

I had that exact error initially... it's because it is generating the wrong "type" of dll... ie. 32bit instead of 64bit.

If you're building manually outside of the docker "fresh_clone"... you need to ensure you have "gcc-mingw-w64" installed:
Then make sure you set the correct GCC_TRIPLET_HOST variable when running contrib/make_libsecp256k1.sh. I believe the comments in contrib/make_libsecp256k1.sh were updated to reflect which command you needed. Refer: https://github.com/spesmilo/electrum/commit/875e6b31b1d4fa0e133a7176e7592361c45beee7

Perfect! Thank you so much HCP!
I should have known something was up with the libsecp255k1-0.dll compilation. Whenever I ran the script on my Ubuntu VM it would finish up with the following error. I kept thinking it was a file permission thing, was trying to work around it.
Code:
error: could not copy secp256k1 binary to its destination

Status report:
I did indeed have a copy of libsecp256k1-0.dll available in my previous builds, and I copied the file to the "~\electrum_master\electrum" directory in my Windows box. Electrum runs in my Ubuntu VM just fine, and the binaries I generated just this morning run fine as well. There doesn't seem to be any issue with the libsecp256k1-0.dll file itself, but I still get this error when trying to run it from source:
I'm using Windows 10 v. 1903

I'm running it from source.
But, I assume that worked for you, and that's all I need to run Electrum from source on my Windows 10 machine?But earlier builds doesn't require "libsecp256k1", only when enabling Lightning (until Feb12).
Thanks for the link, but I really just wanted to do it myself as a learning opportunity. It didn't occur to me that since I've already compiled the binaries (several times now,) I should have that file myself, right? I'll have a look when I get home.
Not necessarily... unless you have explicitly installed the appropriate libraries, the Windows build will still complete "OK" (with errors that scroll past) and binaries will be built... but the libsecp256k1 stuff will be missing and you'll get errors when you try to run it... as per this post: https://bitcointalksearch.org/topic/m.53807327If you have "libsecp256k1-dev" installed in Ubuntu (with apt-get)... and the python library "libsecp256k1" installed (with pip)... then the build-wine process will automatically compile the libsecp256k1-0.dll and roll it into your binary file. You can also find this compiled .dll and then copy it to a Windows machine and put it into your Electrum "source" folder to be able to run from source.
Why not just install the copy from HCP to try?
I learned to compile my own binaries a little while ago so I could test the pre-beta version, but now I'm having fun working with python and learning more and more as I experiment. I'm finding that to be quite a bit of fun. Weird, huh? Working with command prompt is sort of nostalgic for me, having grown up with DOS and Unix.
I posted links to the portable binary file that I built myself here:
Electrum portable executable: https://drive.google.com/file/d/1Tua1pnLztCZsIcQJBFtdmYmLsGY2qhZQ/view?usp=sharing
I think we already talk about this "libsecp256k1" from another thread here https://bitcointalksearch.org/topic/electrum-400a0-new-feature-5222986
So, I think the copy from HCP includes the "libsecp256k1"

I knew someone had discussed it already, I thought it was in this thread but couldn't find it. Thank you for that.
Yeah, I've tested it on Windows 10 running from source as well... so I've put the compiled ibsecp256k1-0.dll on zippyshare too: https://www92.zippyshare.com/v/CucF6mf9/file.html
Let me know if it works ok!

Do you have any other links? It's blocked on Mediafire look at the image below.

Can you re-upload the file to other hosting sites I suggest you upload it here zippyshare.com. and post it here or pm the link.
Thanks in advance...

It would seem it is freaking out about pyinstaller and blocking the file

I literally laughed out loud when I saw who posted the issue; "hey I know that guy," I said to myself. I'm at the office today, so I don't have time to try compiling the libsecp256k1-0.dll, and I don't have a Linux vm installed on my work machine anyway (time to fix that.)

I have compiled and uploaded a snapshot of 4.0.0a0 as at 30th March 2020... It is available here: http://www.mediafire.com/file/50jvn15ysgj8qsd/electrum-3.3.8-1845-g79d57784c-portable.exe
Ignore the filename, it's just a quirk of the build system as discussed earlier in this thread.
As always, Use at your own risk. I accept no responsibility if something goes wrong and you lose coins... TestNet is there for a reason!
Seems my channels got closed while I've been offline due to moving etc

I'll retry it periodically or open another channel, might be a connection or routing issue.
Update: Eclair failed to send through lightning too, it worked for me, tried just now (maybe your client was closed for some reason?).

I just checked it now, my channel disconnected for some reason. Tried to restart Electrum, but still couldn't get it reconnected. Well, that one's a gonner. I'll open another channel and post another request tomorrow.
As for the settings, I set all lightning-related to default/blank.
I'm using the 2020 March 18 Build (today's latest available build).

And let me ask if what will happen if I close my open channel? What will happen to my test coins?
If you close your channel, the funds will be back to your mainchain balance;
if you force-close it, the funds will be back after a day.
(may be wrong)
Okay, I'll try again, here's a request for 100 sats set to expire in 24 hours. I'll keep the client running all night.
I'm getting the same result when sending to a disconnected channel.But it's not the same error when you try to send to a single PC with multiple instances of Electrum.

And I need a new copy because the last build(February build) is accidentally deleted with my Kaspersky antivirus(I don't know why but the January build detected as fine.).
And let me ask if what will happen if I close my open channel? What will happen to my test coins?
Did you set something from settings? Maybe I miss some settings that's why it doesn't work.
I got the copy from HCP the latest build and I'm currently using windows 7.
Try to open a channel with (node id): 0269a94e8b32c005e4336bfb743c08a6e9beb13d940d57c479d95c8e687ccbdb9fI got the copy from HCP the latest build and I'm currently using windows 7.
I have noticed that Electrum has been using my channel that's connected to that node to purchase virtual coffees instead of the other ones.
That's a random node id result that I got when searching for channels using "suggest" button.
As for the settings, I set all lightning-related to default/blank.
I'm using the 2020 March 18 Build (today's latest available build).
I'm wondering if this is an issue with Electrum itself, and not the fact that I'm using the wallets on the same computer. Would one of you be so kind as to help me test this theory? Here's a testnet request for 100 satoshis, please only only use Electrum to fill this request.
-snip-
At least keep your Electrum online while you're away so others/I can try to fill that invoice.-snip-
I've done some test too, I successfully received some satoshi from my Eclair Wallet. [Eclair->Electrum]
@all Try mine instead (use only Electrum):
