[sane-devel] Compilation errors with snapscan and Irix

[Henning Meier-Geinitz]

Hi,

I just tried compiling sane-backends on Irix 6.2 and got the following
error:

cc -c -g -DHAVE_CONFIG_H -I. -I. -I../include -I../include -D_GNU_SOURCE -DPATH_SANE_CONFIG_DIR=/tmp/sane-bin/etc/sane.d -DPATH_SANE_DATA_DIR=/tmp/sane-bin/share -DV_MAJOR=1 -DV_MINOR=0 -DBACKEND_NAME=snapscan -DLIBDIR=/tmp/sane-bin/lib/sane snapscan.c  -DPIC -o .libs/snapscan.lo

gmake[1]: *** [snapscan.lo] Error 1

gmake: *** [all-recursive] Error 1

Looks like the test

#if defined(__GNU_LIBRARY__) && !defined(_SEM_SEMUN_UNDEFINED)

doesn't catch this.

If it is really a bug, can this be fixed before release? As this stops
sane from working on Irix, the bug fix is allowed even after code
freeze.

Bye,
