Now that autotools is used as a build system there is nothing special about building the GUI anymore. People were getting confused about the lack of any real build instructions in readme-qt.md. Merge the salvageable parts into build-unix.md.

Diapolo commented at 1:03 PM on October 15, 2013:

There are still autotools patches to come for this, right?

laanwj commented at 1:20 PM on October 15, 2013:

It doesn't work like this yet?

Diapolo commented at 1:40 PM on October 15, 2013:

AFAIK you currently can't use Qt5 with our autotools!? I remember @theuni mentioned he planed to add Qt5 patches soon.

laanwj commented at 1:45 PM on October 15, 2013:

I'm still using Qt4, so I don't know. Would be pretty sucky though if we lost Qt5 support :/

Diapolo commented at 1:49 PM on October 15, 2013:

Well and I'm still using the .pro, so I can't verify either...

I am testing the new build instructions with Ubuntu 13.04.
- Figuring out the dependencies is hard, given that different Ubuntu version schemes are used (sometimes Ubuntu Precise, sometimes Ubuntu 12.04). It's sometimes not clear if the doc implies "and later" or "and earlier".
- $ ./autogen.sh Can't exec "libtoolize": No such file or directory at /usr/bin/autoreconf line 195. Use of uninitialized value in pattern match (m//) at /usr/bin/autoreconf line 195.
laanwj commented at 1:16 PM on October 15, 2013: member

For libtoolize, can you try to install "autotools-dev"?
schildbach commented at 1:23 PM on October 15, 2013: contributor

@laanwj autotools-dev is already installed.
laanwj commented at 1:24 PM on October 15, 2013: member

"libtool" then
schildbach commented at 1:33 PM on October 15, 2013: contributor

package libtool is fine, autogen succeeded. Now ./configure fails at

checking for Berkeley DB C++ headers... no configure: error: libdb_cxx headers missing

I assume this is due to libdb* packages missing, however none of the alternatives worked for me:

Package libdb4.8++-dev is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

Same for libdb4.8-dev.

laanwj commented at 1:35 PM on October 15, 2013: member

You're using these?

db4.8 packages are available [here](https://launchpad.net/~bitcoin/+archive/bitcoin)

schildbach commented at 1:38 PM on October 15, 2013: contributor

No, I was hoping I can satisfy all dependencies from the Ubuntu repositories. Is this possible?
laanwj commented at 1:42 PM on October 15, 2013: member

That's not possible, there are no bdb 4.8 packages in the repository for 12.04 and later. You can use a newer bdb but once you use that you break binary wallet compatibility thus is not recommended (that's literally in the build instructions).
sipa commented at 1:46 PM on October 15, 2013: member

If you were already compiling bitcoin(d/-qt) before on ubuntu, you were likely using bdb 5.1 anyway, and you already lost that compatibility. In any case, nothing a db_dump + db_load can't solve if you really need to downgrade bdb.
schildbach commented at 1:50 PM on October 15, 2013: contributor

Yes, for now I installed bdb 5.1 from the Ubuntu repositories again.

Also, I needed to install "libprotobuf-dev" (missing in the doc).
schildbach commented at 1:52 PM on October 15, 2013: contributor

Now, I get

checking if qt should be enabled... configure: error: "qt support requested but qt could not be located. use --without-qt"

I have installed libqt5gui5 libqt5core5 libqt5dbus5 qttools5-dev-tools as documented. Did not try the qt4 path.
laanwj commented at 1:53 PM on October 15, 2013: member

I'll add libprotobuf-dev.

Ok so it seems that @diapolo is right and Qt5 is no longer supported at the moment :(

special about building the GUI anymore. Merge the salvageable
parts into build-unix.md

schildbach commented at 1:59 PM on October 15, 2013: contributor

Ok, going the qt4 route then.

Is "checking if ccache should be enabled... configure: ccache not found. Falling back to default CC no" expected?
laanwj commented at 2:00 PM on October 15, 2013: member

Yes, ccache is not necessary for a build but can be used.

doc: build with qt5 is currently not possible

Add as a separate commit so that it can be easily reverted once
Qt5 is supported again.

schildbach commented at 2:44 PM on October 15, 2013: contributor

@laanwj what would be the package for ccache?

I managed to build bitcoin-qt using the instructions. Thanks for your help!
laanwj commented at 4:22 PM on October 15, 2013: member

I think the package is simply 'ccache'.
schildbach commented at 4:27 PM on October 15, 2013: contributor

Yes, that works.

Missed the index link in the /doc readme. See #3097
rebroad commented at 10:37 PM on December 27, 2013: contributor

still seems that the libprotobuf-dev isn't mentioned in the build docs... shall I do a pull request for this?
laanwj commented at 2:25 PM on December 29, 2013: member
libprotobuf-dev, as well as protobuf-compiler IS mentioned in the build docs:
```
To build with Qt 4 you need the following:

    apt-get install libqt4-dev libprotobuf-dev protobuf-compiler
```
