Hi Currently testing with a LIDE 20...
Compilation fails: sanei_thread.c: In function `local_thread': sanei_thread.c:159: warning: control reaches end of non-void function sanei_thread.c:160:3: warning: style of line directive is a GCC extension sanei_thread.c:207:3: warning: style of line directive is a GCC extension sanei_thread.c: In function `sanei_thread_waitpid': sanei_thread.c:272: `PTHREAD_CANCELED' undeclared (first use in this function) sanei_thread.c:272: (Each undeclared identifier is reported only once sanei_thread.c:272: for each function it appears in.) make[1]: *** [sanei_thread.o] Error 1 make: *** [all-recursive] Error 1 After quickhack-workarounding those errors it works. The reader process starts, but obviously then something goes wrong, the app just hangs after [sanei_lm983x] sanei_lm983x_read: read 2556 bytes [sanei_lm983x] sanei_lm983x_read: succeeded [plustek] usb_ScanReadImage() done, result: 0 [plustek] reader_process: finished reading data [plustek] sane_read - read 1269 bytes [plustek] sane_read - read -1 bytes Regards Beat H.
