Building headless Bitcoin and Bitcoin-qt on Windows

[Cassey]

I took me at least two 40 hour weeks to get my first coin to build under windows.  It took 5 minutes under Linux.  Once you get the environment setup right, it will go easier.

the windows wallet can't be built under linux though right?

In theory you could cross-compile, spent a week trying, on and off, and never got there.  Always one piece that wouldn't fit in the puzzle.

Been trying to build for months off and on... Followed the instructions to the letter and on any build, I always get the same exact error message when I try to run the otherwise cleanly compiled executable:



What am I doing wrong here?

Windows 7 x64 build environment which is freshly installed in a VM.

If I try to copy content of winsock2.h and replace ws2tcpip.h, i will get an error at netbase.cpp where it need ws2tcpip.h , so I can't really fix this part

#error "ws2tcpip.h is not compatible with winsock.h. Include winsock2.h instead."

what should i do..

You are most likely using the wrong toolchain. You should use one of the latest mingw-builds toolchains.

Windows executables can be cross-compiled on gitian. See http://gavintech.blogspot.it/2014/02/gitian-building-bitcoin-releases.html

Not crashing here. Make sure your build environment and project file are ok.

As I said, it's a clean build environment. Fresh Windows 7 install. Followed the first post to the letter. Compiles clean, but any coin I compile produces similar errors.

at make -f makefile.release I get

Code:

ld.exe: cannot find -ldb_cxx

In the .pro file the path BDB_LIB_PATH point to the directory with db_cxx.h
also, how to I get a log from make?

If one studies the makefile, one sees that the -lxxx refers to a file in the -LpathWhateverDirectory whose name is libxxx.a

So do you have such a file in that place?  If not, then either it wasn't built, or was built but put elsewhere (or erased, renamed,...)  Can't think of too many orther possibilities

Ron

I can find db_cxx.h in the "BDB_LIB_PATH=c:/deps/db-4.8.30.NC/build_unix" and when I built Berkeley DB I used --enable_cxx

Let's try again,

Did you see my message above?  I made it bigger this time   So when one sees a gcc argument like -ldb_cxx one should find a file named libdb_cxx.a there.  Notice how -lssl becomes libssl.a, etc.

Hint: one must observe and generalize from the patterns shown in the makefile.  It's all there if one just looks. Perhaps this has helped others.

Ron

So I checked in c:/deps/db-4.8.30.NC/build_unix I couldn't find db_cxx.a, did I build it wrong?  I also ran a full HD search and found nothing.  Thanks for your help!

That is why I'm trying to offer an alternative build platform for Windows. The bitcoin source is the same. Not changed at all. Except with changes as above. Should be easier to pretty up a windows version in MSVC than in Qt. At least it seems so to me at this time. Qt is fine but it seems to have a lot of compatibility issues with its compiler, its libraries, etc.

Anything yet ?

Hello Eternity,

Sure looks like my words there!  Oh it is, see message #322 (digest #17) of January 07, 2014, 03:34:12 PM https://bitcointalk.org/index.php?topic=149479.msg4371673#msg4371673

To put it in context, see #228, digest 12, November 30, 2013, 06:40:00 PM https://bitcointalk.org/index.php?topic=149479.msg3785964#msg3785964

and #381 (digest #20), February 13, 2014, 03:02:10 AM https://bitcointalk.org/index.php?topic=149479.msg5114756#msg5114756

I have succeeded in making a MSVC version of bitcoind.exe  The testing has been going on for about two weeks now.  Now it is "catching up" on the block chain and is at the moment about 23 hours behind.

It is an 0.8.6 version and is built using the four libraries: Boost 1.53, OpenSSL 1.0.1e, BerkeleyDB 4.8.30 and levelDB 1.13.  All MSVS built, multi-threaded and static.  The release mode exe is 3,976KB (3.88MB [4,071,424bytes]) in size as compared to the gcc version which is 6,548KB (6.39MB[6,704,640byts]) in size.  The debug version as an aside is 17,704KB (17.2MB[18,128,896bytes]) in size.

I share the honor of having an all MSVS (Microsoft Visual Studio) port of the gcc port of the bitcoind.exe code with Claire123.  Hers is for VS 2012 and is both for bitcoind and bitcoin-qt!  See her forum https://bitcointalk.org/index.php?topic=349094.0;all Here they come, I can hear the digital stampede now

My version is for MSVC++ 2005 Express and as it is the first and "lightest in weight" it is by definition upwardly compatible with all later versions of VS and VS Express: 2008, 2010, 2012, 2013.  And it was also done on Windows XP (SP2) so as to be the most compatible with the majority of internet connected Window's desktop units.  See http://www.netmarketshare.com/?source=NASite and select [Operating Systems]=>[Desktop Share by Version]

Finally, it has been running for half a day or so and has settled down to consuming ~390 MB of memory.  Task Manager says 407MB,  procexp.exe says 395MB. The gcc bitcoind.exe (version 0.8.3) uses ~250MB.  It is the only one I measured for any length of time.

Hello all,

Here is a live pix worth 1K words.

There is a lot in there.

Notice the 5 transactions hi-lighted in color on blockchain.info and hi-lighted on the running MSVC++ bitcoind.exe.  Also the ~117MB being used by bitcoind.exe according to procexp.exe.  Another bitcoind.exe just RPC quizzed the MSVC++ version for getblockcount, actually getblockcountt.  I added a command to give the block number and its blocktime so I could see easily how the "catch-up" was going. And on the right is MSVC++ Express having just compiled 3 of the files and linked them in 1:52 (1 minute and 52 seconds) to produce the program that is running.  I just commented (//) out a few printf()s to quiet the printtoconsole output a little so that I could capture the transactions as they go scrolling by.  If one looks closely one can see this forum open in another browser window in the background.

There is an issue that compiled the wallet, I got some error like

the application has requested the runtime to terminate it in an unusual way



anyone can help on this?

Boost 1.55 seems to be broken for me.
When I run

Code:

bootstrap.bat mingw

I got some errors like:
"VCVARS32.BAT is not recognized as an internal or external command" like in this thread: http://b1te.de/5N
So I moved to Boost 1.54 and I can run

Code:

bootstrap.bat mingw

now without any problems.

See if this fix helps:
https://groups.google.com/d/msg/boost-developers-archive/hVNKGbZcXs0/fIh-iK-DVOMJ

Actually I got a problem to create the Bitcoin-qt.
I got messages like CC is not found.

Code:

C:\testcoin>mingw32-make -f Makefile.Release
cd C:/testcoin/src/leveldb && CC=gcc CXX=g++ TARGET_OS=OS_WINDOWS_CROSSCOMPIL
E mingw32-make OPT="-pipe -fno-keep-inline-dllexport -D_FORTIFY_SOURCE=2 -O2" li
bleveldb.a libmemenv.a && ranlib C:/testcoin/src/leveldb/libleveldb.a && ranl
ib C:/testcoin/src/leveldb/libmemenv.a
Der Befehl "CC" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.
Makefile.Release:317: recipe for target 'C:/testcoin/src/leveldb/libleveldb.a
' failed
mingw32-make: *** [C:/testcoin/src/leveldb/libleveldb.a] Error 1

-> But CC = gcc is specified and it worked to create the headless version.
I use Qt 5.2 maybe I should try it with another version.

Did you remove leveldb build instructions from your .pro file?

Thanks man , it save me!
Just post the solution directly hereh:

Adding an empty!! new line in

$BOOSTDIR/tools/build/v2/engine/build.bat

in line 93 right before:
:Guess_Toolset

After that

cmd /c 'bootstrap.bat mingw'

Works as expected again in msys command environment.

How to fix this error with ws2tcpip.h is not compaitable with winsock.h Include winsock2.h instead
If I take away ws2tcpip.h, it will end up issue at netbase.cpp where its use parameter of ws2tcpip.h , anyone can help resolve this

Trying to build max coin window qt, but have this issue.

[Stygian0708]

Can someone please help me with this issue, I don't know what I did before to fix it but I just installed win7 in a vm to give it a try on windows7 instead of windows 8 and I am back at to the following error. I have tried installing MinGW over I know someone said install msys over mingw but I have no clue what they are talking about as haven't clarrified t hemself when asked what they meant, so any help would be greatly appreciated. I have also checked my path variables and everything seems to be correct.

Make sure you are building the libleveldb.a and libmemenv.a libraries before you compile JennyCoin

from msys shell

Code:

cd /C/JennyCoin/src/leveldb
TARGET_OS=NATIVE_WINDOWS make libleveldb.a libmemenv.a

When I go to make Qt 5 for feathercoin-qt.pro I receive a long list of these error outputs after

qmake feathercoin-qt.pro

Code:

Project MESSAGE: Building with UPNP support 
Warning: ignoring <defaultcodec> element
Warning: ignoring <defaultcodec> element 
Warning: ignoring <defaultcodec> element...  

Is this normal?

*EDIT* I assume this is normal as I have successfully compiled feathercoin-qt.exe

I then received this error after

mingw32-make -f Makefile.Release

Code:

g++: error: unrecognized command line option '-Wl'
Makefile.Release:294: recipe for target 'release\feathercoin-qt.exe' failed
mingw32-make: *** [release\feathercoin-qt.exe] Error 1

I checked the feathercoin-qt.pro file and there was a difference in the win32:QMAKE_LFLAGS before the one where we are supposed to add -static where it only had

Code:

win32:QMAKE_LFLAGS *= -Wl 
instead of 
win32:QMAKE_LFLAGS *= -Wl, --dynamicbase -Wl, --nxcompat

So I changed that and I just receive the errors

Code:

g++: error: unrecognized command line option '--dynamicbase'
g++: error: unrecognized command line option '--nxcompat'
Makefile.Release:294: recipe for target 'release\feathercoin-qt.exe' failed
mingw32-make: *** [release\feathercoin-qt.exe] Error 1

Any advice on this?

*EDIT*

I fixed this by commenting out the entire line in the feathercoin-qt.pro.  Might want to try adding -static to the end of the extra QMAKE_LFLAGS line too, didn't try that.

Code:

# win32:QMAKE_LFLAGS *= -Wl,

I'll leave this up in case anybody else comes across this g++ error.

Make sure you are building the libleveldb.a and libmemenv.a libraries before you compile JennyCoin

from msys shell

Code:

cd /C/JennyCoin/src/leveldb
TARGET_OS=NATIVE_WINDOWS make libleveldb.a libmemenv.a

Thanks for the help but not doing that isn't going to give me the error im getting

[Kergekoin]

Trying to compile with msys, but in the end running to error:

c:/mingw32/bin/../lib/gcc/i686-w64-mingw32/4.8.2/../../../../i686-w64-mingw32/bi
n/ld.exe: cannot find -lboost_thread_win32-mgw48-mt-s-1_55
collect2.exe: error: ld returned 1 exit status
make[1]: *** [release/xcoin-qt.exe] Error 1
make[1]: Leaving directory `/c/xcoin'
make: *** [release] Error 2

Suspecting problem with bold part in file name. I dont have any _win32 suffix files in boost/stage/lib directory. Do i need  to create them or adjust .pro file somehow?


Edit: Problem solved. Found controversal line in .pro file.

You should use one of the latest mingw-builds toolchains. See step 1.1 to get a working environment.
