[Dev] Packaging feathercoind and feathercoin-qt on Linux

[wrapper]

Tried to register the Feathercoin name on opensuse build service but it has been taken (and abandoned ) by [email protected]

Gonna contact him to get the name.

Building Feathercoind

0.8.7.3 - buildunit.txt

sudo apt-get install libboost1.37-dev fails

In Kubuntu 15.10 this is now libboost1.58-dev

warning during compile :

There is a mismatch to how ProcessBlock is called in main and rpcmining.cpp - it looks like there is a bug in main.cpp should be &pblock …

Re: Error Compiling Zetacoin Ubuntu
January 29, 2016, 08:41:47 AMI have similar problems with various coins- the solution is usually I try a different version of boost-devel, make clean and recompile.

---

Seems Boost 1.58 is the probable cause : – Found this post

Considering that boost 1.59 seems fine with the code, I’d go for:

if((${Boost_MAJOR_VERSION} EQUAL 1) AND (${Boost_MINOR_VERSION} EQUAL 58))
message( STATUS “Defining BOOST_VARIANT_USE_RELAXED_GET_BY_DEFAULT”)
add_definitions(“-DBOOST_VARIANT_USE_RELAXED_GET_BY_DEFAULT”)
endif()

just after the find_package( Boost … ) in the main CMakeLists.txt

---

Looks like there was a PPA to get the latest Boost version : will continue tomorrow…

https://codeyarns.com/2013/12/27/how-to-upgrade-the-boost-library-on-ubuntu/

Found this :

https://github.com/icook/zmark/commit/40ddb16a05c703c7cd9dce10f3aef09c0679e3d3

Edited line 299 of rpcrawtransaction.cpp

from
const CScriptID& hash = boost::get<const CScriptID&>(address);

to
const CScriptID& hash = boost::get<CScriptID>(address);

Continues further with build then error :

shiftdialog.cpp:28:23: fatal error: QJsonObject: No such file or directory

---

Installed libzxing libqrencode-dev qtbase5-dev libqt5opengl5-dev

Now build fails with new error :

CXX libbitcoinqt_a-shiftdialog.o
shiftdialog.cpp:28:23: fatal error: QJsonObject: No such file or directory
compilation terminated.

Found similar problem compiling MInt

There must be a newer version of that object files other than the one supplied with mint. The version table ends at GLIBCXX_3.4.19

Code: Select all
objdump -x /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.19|grep ‘GLIBCXX_3.4.1’

Tried : Install libstdc+±5 (4.9 installed) build failed

---

Found another similar Mint problem @Wellenreiter worked on :

https://bitcointalk.org/index.php?topic=178286.msg13823798#msg13823798

qtbas5-dev appears to be installed correctly…

QJsonObject: The compiler misses the file qjasonobject.h
As Mint is a kind of special flavor of Ubuntu I checked the Ubuntu packages.
You need to install the package qtbase5-dev. That package contains qjsonobject.h as you can see here:
http://packages.ubuntu.com/wily/amd64/qtbase5-dev/filelist

QtPrintSupport/QPrinter: The compiler misses the file qprinter.h
Again, the package qtbase5-dev contains the header files for QtPrintSupport.
If you have installed qtbase5-dev, check for the directories containing qprinter.h and qjsonobject.h
and specifiy these directories for the configure script. Use ‘configure --help’ for syntax.

Searched for qjsonobject.h and qjsonobject.h not found

---

Found This : https://bugreports.qt.io/browse/QTBUG-27096 :

All instances of “#include <QPrinter>” or “#include <QPrintDialog>” that I had in my Qt4 project must now be replaced by “#include <Qt/qprinter.h>” or “#include <Qt/qprintdialog.h>”, which is not Qt standard.

Edit :
src/qt/utilitydialog.cpp

Actual position of Qt printer headers in Ubuntu 15.10 :
/usr/include/x86_64-linux-gnu/qt5/QtPrintSupport/qprinter.h
usr/include/x86_64-linux-gnu/qt5/QtPrintSupport/qprintdialog.h

Try - Change lines including utilitydialog.cpp headers include from :

// Use QT5’s new modular classes
#include <QtPrintSupport/QPrinter>
#include <QtPrintSupport/QPrintDialog>
#include <QtPrintSupport/QPrintPreviewDialog>

Change lines in utilitydialog.cpp to :
// Use QT5’s new modular classes
#include <QtPrintSupport/qprinter.h>
#include <QtPrintSupport/qprintdialog.h>
#include <QtPrintSupport/qprintpreviewdialog.h>

from : https://bugreports.qt.io/browse/QTBUG-27096
Did you add QT += printsupport in the pro file?
It should work that way. Please let me know if you still have problems.

Can’t find feathercoin.pro in 0.9.3.1 release source.

---

Back to basics ran full instructions :

qmake failed

so ran full build with qmake -project :

make clean
./autogen.sh
autoupdate
./configure --with-incompatible-bdb
qmake -project
make

---

Added QT += printsupport to feathercoin.pro file as suggested here :

https://bugreports.qt.io/browse/QTBUG-27096

Caused early crash of compile with error :

make[5]: Entering directory ‘/home/tony/programs/Feathercoin/src/qt’
CXX libbitcoinqt_a-shiftdialog.o

make[5]: *** [libbitcoinqt_a-shiftdialog.o] Error 1

edited utiltydialog.cpp to try a different “full path” to Qt “problem” libraries.

// Use QT5’s new modular classes
#include <QtPrintSupport/QPrinter>
#include <QtPrintSupport/QPrintDialog>
#include <QtPrintSupport/QPrintPreviewDialog>
#include <QtGui/QPainter>
#include “walletmodel.h”

#include <QtPrintSupport/qprinter.h>
#include <QtPrintSupport/qprintdialog.h>
#include <QtPrintSupport/qprintpreviewdialog.h>

#include “walletmodel.h”

Tried compile with modified headed and …/configure --with-incompatible-bdb --enable-dependency-tracking

build failed.

[Wellenreiter]

too much in one post.

• qjasonobject:
  • is available with qt5 only. I’m not sure, which qt-package I installed to get it, if it is not the one I mentioned in the other thread
• feathercoin.pro
  • doesn’t exist and is not needed for qt5 based compiles

I will try to build for Ubuntu 15.10 and 6.04 with your modification in rpcrawtransaction.cpp. May be I also will try to change the dependency for boost lib to boost <= 1.59

[wrapper]

Don’t worry about the post yet, all is negative. Just documenting what I’ve tried, so Aciddude doesn’t duplicate effort…

Still got a couple more things to grind through. I am starting to run out of ideas to try tho’.

Trying to Install 1.59 is next on my list, I couldn’t easily find a PPA . (There is a bug in 1.58)

That sounds like the easiest fix, now all know mods have been tried. If it worked, it would use the same code, so no special mods needed.

[wrapper]

Now we have the 0.8.7.3 build for Ubuntu is it more sensible to move to (testing) 0.11?

and if 0.8.7.3 and 0.9.3.1 compile on 16.04?

The problem does seem to be a glitch with libboost1.58-all-dev on Ubuntu 15.10 anyway. It seems to be a system dependancy.

I’ve exhausted workarounds to try for the moment.

[Wellenreiter]

I’d prefer to keep the 0.11.x versions on the testnet.
Nevertheless @Lizhi ist using 0.11.2 on the prodnet. I asked him to specify his needs for the testnet, e.g. client versions to test compability and switch over to protocol version 4, but he didn’t come back to me.

May be I can spare some time to try the build on ubuntu 16.04… but… it’s my wifes Birthday next Sunday, so probably I’ll have other duties :d

[UnklAdM]

I’ve got a dev box at home with 14.04 LTS installed on it. Would getting this working on that help at all? If so, what version should I try?

I managed to get my primary wallet running on Centos 7 but that was a totally different scenario.

Just trying to help out, the wife passed 6 weeks ago and I’m trying to keep busy. I’ve been pretty active with Syscoin lately so a lot of this is pretty fresh to me.

- UnklAdM

[AcidD]

@UnklAdM - all I can say is I’m sorry man…

I’m attempting ubuntu 16.04 now and going with Feathercoin v0.9.3.1

There isn’t a problem with building on Ubuntu 14.04 or 15.04,

the problems are now finding why Feathercoin 0.9.3.1 doesn’t build for Ubuntu 15.10 (probably a bug in libboost1.58 Ubuntu dependency).

Looking into whether (the Centos problem) solution of upgrading to 1.59 can be done (compile from source) and run on standard installs of Ubuntu …

and testing 0.8.7.3 and 0.9.3.2 builds on Ubuntu 16.04

Source code :
https://github.com/FeatherCoin/Feathercoin

Build Instructions in /doc for wallet (feathercoin-qt) dependencies : multiwallet-qt.md
Build Instructions in /doc for daemon (feathercoind) dependencies : readme-qt.rst (only available in 0.8.3 currently)

Then (remove the --with-incompatible-bdb to retain 4.8 version dB)

make clean
./autogen.sh
autoupdate
./configure --with-incompatible-bdb
qmake -project
make

[AcidD]

So apparently it compiled…

Feathercoin-qt is 143.2MB

when I try to run it I get an error:
“Could not display Feathercoin-qt”

“There is no application install for “shared library” files. do you want to search for an application to open this file?”

=====
edit: WHOOOP!! IT WORKS
in terminal running sudo ./feathercoin-qt loaded it fine. it’s syncing the block chain now. Screen shots coming.

[AcidD]

BOOM CITY !!

[wrapper]

We might as well concentrate on 16.04 builds (for Ununtu) so …
Since 15.10 is soon to end support, there isn’t a great necessity to have a 9.3.1 build, especially since we can now produce 0.8.3.1 with the fixed dependencies.

I’ll upgrade / set up virtual box to confirm the build works.

I’ll start to look at some pushing updates to the build docs, ie can’t build 15.10 and updated dependency condition.

1st point - there is a compression method to reduce the size for release binaries

from : https://github.com/FeatherCoin/Feathercoin/blob/0.9.3.1/doc/build-unix.md

The release is built with GCC and then “strip bitcoind” to strip the debug symbols, which reduces the executable size by about 90%.

in Feathercoind case

cd src
strip feathercoind

2nd point - don’t run feathercoin-qt as sudo, otherwise the wallet will be put into root …

try running

cd ~/Feathercoin
./feathercoin-qt

or you need to run make install and run feathercoin-qt directly

3rd point found this reference to previous work Wellenreiter did on 0.9.3.1 build.

Just noting Commits on Aug 24, 2015
@enlighter @Bushstar
Update rpcrawtransaction.cpp

A fix in 0.8.7 was not transferred/updated at head to 0.9.3

Note: Have we a way of checking all “Feathercoinpatches” have been applied to the new version? Did we check any Litecoin only patches, that we “used” were brought into the Bitcoin Build?

[Wellenreiter]

We need to maintain release notes, specifying what was implemented in what version. Also the goal must be to have one production release only, which requires a good release planning.

@lizhi : can you add a release notes file, where you specify what you implemented, e.g ‘implemented ACP’ or ‘implemented bib 102’?
I know, that this also is part of a commit comment, so does anybody know a way to create the release notes from the github commit comments?

I never had a problem to run feathercoin-qt as non-root user.
Can you tell what you did to get it compiled?
Did you modify the code?
Did you install additional libraries?

[Wellenreiter]

@wrapper : we should include the strip command in the packaging process and the stripped code NEVER ahould be committed to github, othwise debugging could become a pain.
Also I think that the 143mB binary is a result of static linking, qhwre all libraries are part of the binary. Dynamic linking should reduce the size also and has the advantage, that we don’t need to release a new version, if a library is patched

@Lizhi @Ghostlander @Bushstar

Development procedure

@Wellenreiter Thanks for the update, it’s a complex situation and keeping close to Bitcoin development, at least takes advantage of all their testers.

Although, slower than it could be with dedicated paid staff, the open source “chaos” does seem to work. As you say, so far we have tried to make everything backwardly compatible, where that was not possible, members have moved to the new forks pretty well.

The main thing FTC seems deficient at is a guide or methodology for “upgrading” a Bitcoin fork to include all FTC specific enhancements / settings. Particularly as of the extra complexity of moving from Litecoin fork directly to Bitcoin core.

I could be wrong and Bush, Wellenreiter or Lizhi have a way of doing it but it would assist in finding members who could help, if we get everything documented now.

As far as testing 0.9.3.1 and above, the main thing we must do is test all FTC specific features have been included a work. Even if that is a simple as being “double checked” by someone …

That is the main effort should be in maintaining the fork difference.

We could have a Development thread called FTC additional packages, with each as a post, updated with “install in version” and checked by …

created by the first checker. From a list of commits to 0.6 to 0.8 Feathercoin Github?

List of FTC Pages and system settings / additional files

ACP
Name changes : Bitcoind changed to Feathercoind
images and icons
splash screen
eHRC
neoscrypt
Transaction fees
Block times
checkpoints

etc

Release procedure

To keep things simple and to allow others to help get involved, we also need an updated release procedure post.

It again would be a simple check list, from the git hub readme, so a checker can be allocated and sign of the release steps.

We could of course just point the forum to slight update to the Feathercoin readme, but having it on the forum would help members get involved, reduce errors and spread the development load from staff.
