Hi Dan, Hmmm, this may become a bit lengthy. Let me try and explain why rebaseall is needed. Unix like systems use a system call named fork() to create all new processes by exactly copying the memory content of the current process to make a new child process, this is fundamental to how shells run programs. Because msys is the MinGW (GNU gcc compilers on Windows) shell and is based on Unix principles it needs an emulation of fork() for Windows. Windows has a different way of creating processes with the CreateProcess[Ex]() system call which does something very different. One behaviour of Unix like systems is that in a forked child process any references shared libraries (like DLLs) are loaded at exactly the same virtual address in the new process as the old one. This is an oversimplification as Unix like systems really use a technique called position independent code but it amounts to the same thing. This means that code pre-compiled to call shared library routines will continue to work in the child process. In Windows this can go wrong as DLL code can appear at different addresses in different processes. The rebase action fixes up the msys and MinGW DLLs so that does not happen. So what to do? I suspect that you can install enough of the msys system to allow the rebseall command to work but it might take a few attempts. At least you have the mingw-get tool available now to install new packages. Try this from a JTSDK msys prompt: mingw-get install msys-base and if it works try the procedure to run rebaseall from a dash shell again. 73 Bill G4WJS. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
