    This updates gitian descriptors and adds a few workarounds. Note: THIS DOES NOT WORK, the resulting bitcoin-qt.exe is broken, I'm just pull-requesting this to notify people and let others have a look at the result and attempt to fix the issue.

    Some tips on using gitian to duplicate the broken results: When gitian fails/finishes, you can log into the vm and mess around by doing export PATH=$PATH:libexec; on-target You can see the build-script gitian is executing by looking at var/build-script after the build has started (its pretty much just exporting some variables and running the script in the descriptor). If you want to build from this branch, use -c bitcoin=build-updates instead of master (note that the commit titled "remove this commit before merge" makes the gitian descriptors point to my repo instead of bitcoin/bitcoin)

    Oh, also this hasnt been tested for determinism yet, so there that...

    I'll take a look at this

    OK I'm stuck. How to get started?

    • What kind of AWS image to I need to create?
    • release-process.txt has some information, but it assumes there already is a virtual image with gitian and bitcoin source installed. Do I need to install those myself starting with the Ruby gems etc?

    You can't do this with AWS, it has to be a machine which has VT-x support. There are no gems anywhere here, just git clone gitian-builder and go.

  7. Add gitian descriptor for qt cross compile via MinGW. 6323d005a9
  8. Update Win32 gitian descriptor for bitcoin-qt. 0081f758e5
  9. remove this commit before merge. 6139fc6549

    Note that the build issues are basically Ubuntu issues. Gentoo's crossdev at least has no problems building working EXEs.

    I think I solved this issue!

    The solution appears to be to remove -fstack-protector for the Windows build. Both for the linker and cflags.

    I haven't tested on a Windows machine but the resulting bitcoin-qt.exe works in Wine.

    luke-jr: yes, but we need to understand this issue, I feel it would be a mistake to just abandon it and switch Linux distributions, and hope we'll be ok :)

  12. luke-jr commented at 12:54 PM on October 29, 2011: member

    IIRC it wouldn't even build for me with that flag. ;)

    Now testing whether the build is deterministic and such...

  14. laanwj commented at 5:27 PM on October 29, 2011: member

    The last commit managed to make bitcoin-qt.exe build deterministic. I built it two times and both times the sha256 is the same.

    So the build is now complete. The resulting executable does hang a long time at "Done loading" for some reason I can't explain yet.

  15. laanwj commented at 5:46 PM on October 29, 2011: member

    Hm.. the "Done loading" problem seems to be something local (to do with seeding?), it hangs on connecting to my routers DNS port:

    socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 23
connect(23, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.x.x")}, 16

    I think it is unrelated. Please help testing the gitian script.

    Edit: confirmed: It also happens on Linux now for me, so it has nothing to do with the build.
