Can you try to run on a git libftdi-1.0?
Thanks for the reply.
Compiled and installed lubftdi-1.0 from
git://developer.intra2net.com/libftdi
Compiling ftdi_eeprom, at first it couldn't find libusb.h. I put in a
symlink to that, but then got the errors below. Also tried ftdi_eeprom
branch master from git://developer.intra2net.com/ftdi_eeprom (didn't see
that on the web site but took a guess at the url).
ftdi_eeprom/src/main.c:100: error: storage size of ‘eeprom’ isn’t known
ftdi_eeprom/src/main.c:146: error: too few arguments to function
‘ftdi_eeprom_initdefaults’
ftdi_eeprom/src/main.c:197: error: ‘struct ftdi_context’ has no member
named ‘eeprom_size’
ftdi_eeprom/src/main.c:216: error: too many arguments to function

ftdi_eeprom/src/main.c:218: error: ‘struct ftdi_context’ has no member

/usr/local/include/libftdi/ftdi.h:500: note: expected ‘int’ but argument
is of type ‘unsigned char *’
ftdi_eeprom/src/main.c:218: error: too many arguments to function

ftdi_eeprom/src/main.c:260: error: too many arguments to function
‘ftdi_eeprom_build’
ftdi_eeprom/src/main.c:286: error: too many arguments to function
‘ftdi_write_eeprom’
Seems like it's picking up the wrong ftdi.h file, but this is the only
one I see (other than in the build directories).
/usr/local/include/libftdi/ftdi.h
Any ideas?
Karl
