I know, still have to write them. It is supposed to support the same scanners as epson backend. I have an epson GT-9500 I could try later this weekend. What's the benefit over epson backend? actually, only minor benefits. But I want to be sure I have not breaked compatibility with other scanners. In somewhat near future, epson2 will be able to scan using extended commands (they should be a little bit faster), talk to network capable scanners and to the FilmScan 200. I also would like to collect information on the scanners in order to maintain compatibility in the future. -- Best regards, Alessandro Zummo, Tower Technologies - Turin, Italy http://www.towertech.it

If they are suitable for you then htons, htonl, etc should be pretty
ubiquitous across OS's.
htons and htonl convert from host endian to big endian. I need
little endian to host endian.
the macro i used, which are common under linux, are evaluated
a compile time .
I will search for an appropriate macro in the next few days.

I guess endianness conversion is performed even on OS/2 ;) Hmmm, I think you should not use these macros in userspace anyway! They are not portable an I'm pretty sure building SANE on any platform but Linux will fail. my 2 cents Gerhard

[sane-devel] 3 minor problems with current (20061202) CVS code on OS/2
Hi, two minor problems on OS/2 with current CVS (since 1. 12. 2006) 1. configure (generated by Autoconf 2.59e) fails and claims not to find grep (which is bogus) Running autoconf (2.59) locally solves the problem. 2 I have to add #include sys/socket.h to .sanei\sanei_tcp.c because otherwise AF_INET is not defined. 3. : *** No rule to make target `libsane-epson2.la', needed by `all'. Stop. probably a temporary problem until epson2 - code is added.. Thanks for listening Franz

[...] dunno how to resolve the autoconf problem though... maybe only configure.in should be shipped. I have also fallen for this and been the Bad Man to break the OS/2 build by simply using the default autoconf installed on my debian box! The solution is just to install autoconf 2.59 (eg: from tarball), use that to generate ./configure, test and check in the result. There used to be a note about correct autoconf versions on the SANE website although a quick search just now failed to find it. cheers, Jon == Jon Chambers = http://www.jon.demon.co.uk, 020 8575 7097, 07931 961669 =
