build of urbanlightscape fails on 32-bit

[ibka]

I am trying to build urbanlightscape on Salix xfce 14.1 32-bit but it fails.
First it fails on boost, boost is a dependencies.

After installing boost it fails with this:

Code: Select all

There is no problem on 64-bit

Confirmed. There is something wrong with the slackbuild. Try this:

Code: Select all

cd /usr/src/slapt-src/graphics/urbanlightscape
sudo vi urbanlightscape.SlackBuild

go to lines 44 and 47 and change them to:

Code: Select all

SLKCFLAGS="-O2 -march=native"

save and exit and then:

Code: Select all

sudo sh ./urbanlightscape.SlackBuild

and the package should be built and you can install it with:

Code: Select all

sudo spkg /tmp/urbanlightscape-*.txz

Worked for me at least...

Before i noticed your answer, i found another way yesterday to get it to compile.
I added -msse to that lines
