      It means the flags haven’t been set up properly. Maybe compiled without the assembly code.

          It should be adding the assembly, if you try and compile without setting AM_PROG_AS it complains. I’ll take a look at it and see what’s wrong.

            Error creating wallet.dat from scratch.

            Works with release 0.9.6.1 Doesn’t work with --incompatible database.

            BDB 4.8 and 5.1 have worked previously, seems to be issue with bdb 5.3

                [FAQ] Is it trivial to change a Feathercoin portable wallet file to libdb 4.8?

                Version 4.8 is not a requirement, just a recommendation. You can compile your own version and use newer versions of BDB by passing --with-incompatible-bdb to configure.

                The main reason it is discouraged is because it breaks compatibility with the pre-built binaries. If you’re building from source you may not care.

                But even if you do, it is trivial to convert your wallet back to a 4.8 wallet if you’re stuck with a 5.1 or 5.3 one. Use the bdb tools (packages db4.8-util db5.1-util on Ubuntu):

                Code:

                db5.1_dump wallet.dat.db5 | db4.8_load wallet.dat.db4

                    [FAQ] Is it trivial to change a Feathercoin portable wallet file to libdb 4.8?

                    Version 4.8 is not a requirement, just a recommendation. You can compile your own version and use newer versions of BDB by passing --with-incompatible-bdb to configure.

                    The main reason it is discouraged is because it breaks compatibility with the pre-built binaries. If you’re building from source you may not care.

                    But even if you do, it is trivial to convert your wallet back to a 4.8 wallet if you’re stuck with a 5.1 or 5.3 one. Use the bdb tools (packages db4.8-util db5.1-util on Ubuntu):

                    Code:

                    db5.1_dump wallet.dat.db5 | db4.8_load wallet.dat.db4

                    https://bitcointalk.org/index.php?topic=502482.0

                    Well if one needs to convert the db, it would be easier to export the private keys, compile a wallet with the desired bdb version and import the private keys again.

                    Our precompiled Linux binaries contained in the installation packages care compiled with the default bdb contained in the distributions, so they will work on a given system/distribution.

                      Good idea but (re: Catch22) I can’t read the wallet.dat to export the private keys, as it says it is corrupt.

                          A new version of zxing-cpp (zebra crossing QR code library), has been released.

                          https://github.com/glassechidna/zxing-cpp/pull/57

                          *   Installation working as a configuration package
                          *   Fix source listing to not use GLOB per CMake recommendation. Files
                              are listed explicitly in source_files.cmake so that if file listing
                              changes, CMake can detect it and regenerate as needed.
                          *   Added debug postfix for libs for side-by-side installation of different
                              build variants (libzxing.lib and libzxing-debug.lib on Windows)
                          
                          Notes:
                          
                          *  Proper versioning is not being done in the installation config package. If a version is known, it should be added.
                          *  I had to comment out the windows-specific stuff (core/win32) because it caused compiler issues in Windows SDK headers.

                              A new version of zxing-cpp (zebra crossing QR code library), has been released.

                              Just triggered a build on the package repository.

                                  First block with error message is block : 432000 (const int nForkFour = 432000;)

                                  ERROR: matches claimed amount, CheckProofOfWork()
                                  

                                  All blocks after that have the message, checked up to block 1877425

                                      The first time it does preliminary checks it says hash is different to what it then goes straight through CheckProofOfWork()…

                                      hash=d31a46d558974e7b07c6f63a594bfba0fa435659ebca05108f669f58a6d34cfc

                                        Neoscrypt is little endian, may be a byte swap will do the trick.

                                        Was fighting with that for p2pool already.

                                        Here is the python code snippet to get it running in p2pool.

                                         getwork._swap4(pack.IntType(256).pack(x['previous_block'])).encode('hex'), # prevhash
                                                x['coinb1'].encode('hex'), # coinb1
                                                x['coinb2'].encode('hex'), # coinb2
                                                [pack.IntType(256).pack(s).encode('hex') for s in x['merkle_link']['branch']], # merkle_branch
                                                getwork._swap4(pack.IntType(32).pack(x['version'])).encode('hex'), # version
                                                getwork._swap4(pack.IntType(32).pack(x['bits'].bits)).encode('hex'), # nbits
                                                getwork._swap4(pack.IntType(32).pack(x['timestamp'])).encode('hex'), # ntime
                                        

                                        Definition of swap4:

                                        def _swap4(s):
                                        if len(s) % 4:
                                            raise ValueError()
                                        return ''.join(s[x:x+4][::-1] for x in xrange(0, len(s), 4))
                                        

                                        Not sure, how to realize that in C++

                                          Testing 0.9.6.2- head

                                          @Wellenreiter @Bushstar
                                          I have tested head and am unable to compile with --qrcodes=yes

                                          undefined reference to ` QRCodeDialog::QRCodeDialog(QString const&, QString const&, bool, QWidget*)’

                                            try --with-gui=qt5

                                            qt4 support is broken in 0.9x, but tested first and then selected by configure.
