    [FAQ] How do I create a file of the Feathercoin blockchain that I can import into other wallets?

    You can concatenate the FTC blocks into a bootstrap.dat file. This bootstrap.dat file can be copied into the .feathercoin or blockchain directory of the new wallet.

    When it starts the new wallet will recognize the bootstrap.dat and import the blockchain from disk, but will do all the normal synchronization validation checks in the process. Do not restart as it will rename the bootstrap.dat and proceed online.

    You can lelete the bootsrap.dat after the sync.

    Find your local blockchain:

    cd ~/.feathercoin/blocks
    

    Concatenate all your blkxxxxx.dat files and place the result in bootstrap.dat:

    cat blk* > bootstrap.dat
    

    In Windows :

    COPY /b blk0001.dat+blk0002.dat bootstrap.dat

    Console message :
    SSE2 unsupported, optimisations disabled

    init.cpp ~L480

    opt_flags = cpu_vec_exts();
        if(GetBoolArg("-sse2", true)) {
            /* Verify hardware SSE2 support */
            if(opt_flags & 0x00000020) {

                nNeoScryptOptions |= 0x1000;
            } else {

            }
        } else {
            printf("SSE2 optimisations disabled\n");
        }
    

    Notes

    SSE2 stands for Streaming SIMD Extensions 2 which is a standard on processors for a long time. This will enhance the security of your hardware against malicious software attacks by viruses and other malware.

    These three are actually a hard core requirement for Windows 8 installation. If anyone of them is missing, Windows 8 will not install on your computer. So this has to be taken care even before you buy a new license of Windows 8.

    https://stackoverflow.com/questions/2403660/determine-processor-support-for-sse2

    Call CPUID with eax = 1 to load the feature flags in to edx. Bit 26 is set if SSE2 is available.

    https://gist.github.com/hi2p-perim/7855506

    I’ve output the value of opt_flags
    opt_flags : = 0 SSE2 optimisations disabled

    Putting -sse2=false or true seemed to work , so -sse2 is true

    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.

    [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

    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.
