[Dev] Feathercoin 0.9.6.2 * Maintenance fix, build & upgrade issues notes.

Wellenreiter

I have seen that several times dunig my tests with 0.9.6.* . The ORPHAN BLOCK COUNTER going up to
ProcessBlock() ProcessBlock: ORPHAN BLOCK 751.

It seems there was a number of forks happening, which where resolved later. I can’t remember the block height where it happened, so I can’t tell, that is is the same block where the messages started to show up

There was a problem opening the file “/home/tony/projects/Feathercoin/src/main_LOCAL_17197.cpp”.

There was an encoding conversion error and it was needed to use a fallback character

Chinese character / comment?

Wellenreiter

yes, there are several everywhere in the code.

causing problems to open the files in qt-creator,

It appears that Lizhi has reused debugdialog from stealth coin coin search to demo smart contracts. Will save SX debug as debugdialog.ui.1 till resolved / contract test assesed.

Test : failed
QRcodes in 0.9.6.1 - Only the buttons are visible? has the ui file gone?

Wellenreiter

@wrapper without the ui file you’d get errors during compile, as some signals/slots are missing.

This is testing the 0.9.6.1 release. Just noting, haven’t investigated why …

@wrapper I have the same with 0.11.2
buttons are there, but nothing happens

This will HAVE to be fixed for the next release, the main issue is the MacOS build will fail on this warning… linux and windows the build continues with the warning.

@AcidD Hate to pile on another request, but can you target at least El Capitan compatibility for the next official build? The 0.9.6.1 build cannot run on 10.11, so I’m stuck with looking at a yellow upgrade banner for a while. Did you compile on 10.12 for a reason, deps, etc.?

bluebox

@AcidD Sorry, that wasn’t a very “community effort” post I made… “Ask not what Feathercoin (dev’s) can do for you, ask what you can do for Feathercoin” :)

I’ll try my hand at compiling the official 0.9.6.1 release on 10.11 (physical Mac, not VM’s!) given your instructions here. 'Bout time I did some Mac compiling, been living in the linux world too long. I do have a 10.12 system to test forward compatibility.

DIY, baby!

Follow this one
https://forum.feathercoin.com/topic/8769/guide-build-feathercoind-feathercoin-qt-v0-9-3-1-on-macos-sierra

it’s a proper guide I wrote for the 0.9.X series…it is still valid for 0.9.6.1

See post 1.
