notes: sane-backends 1.0.27 and sane-backends-master-e13b80fa built
and work so issue is with new c++ genesys implementation or
in other words my antiquated system and tools
i have tried -std=c++11, -std=c++14, -std=gnu++11 and -std=gnu++14 without
any change so either my c++ math headers are inadequate or i need additional
pow overloading declarations or ???.
It would help if you mention which git revision you're using when you
get these errors. The genesys backend code is changing on an almost
daily basis :-)

well got a static tarball from gitlab iirc, is dated 2019-09-14 15:54:37 -0700
i had hoped that once the release hit the skids the changes would slow
down a bit, wishful thinking on my part.
Recently some changes were made to get it to build again on Ubuntu 16.04
which also uses an "ancient" C++ compiler (g++-5.4.0, I believe).
if g++-5.4.0 is ancient 4.9.0 must be pre-historic :-)
If you still have compile errors, please attach your config.log and a
full log of your `make` output. A .tar.gz attachment is fine.
have yet to do anything beyond make all check which all tests run pass.
made following casts to the 3 offending pow errors i encountered. i believe
they are safe from inadvertently changing the parameter, but would like
an expert to concur (opine).
2 in backend/genesys.cc
around 761 line changed from
value = gamma_max * pow ((float) i / size, 1.0 / gamma);
to
value = gamma_max * pow ((float) i / size, (float) 1.0 / gamma);
around 1211 line changed from
exposure_factor = pow (2, tgtime); /* todo: originally, this is always 2^0
! */
to
exposure_factor = pow ((double) 2, (double) tgtime); /* todo: originally, this is always 2^0 !
1 in backend/genesys_low.cc
line around 157 changed from
pixels_per_line, lines, (int) pow (2, depth) - 1);
to
pixels_per_line, lines, (int) pow ((double) 2, (double) depth) - 1);
i actually wrapped each in a conditional for solaris, but have yet to rebuild
will submit the diffs when i've actually done a scan or 4.
as for the configure autofoo stuff; yeah that was a bit of a struggle and still
have a problem not having the newest and greatest libtool 2.4.6. is there a
requirement for 2.4.6 unmet with an older (err ancient) version like 2.2.6?
note: looks like LT_PREREQ([2.4.6]) was added at sane-backends-master-e13b80fa,
sane-backends-1.0.27 had no LT_PREREQ criterion at all.
