mandelbulber slackbuild

pzognar · 12-22-2015, 05:40 AM

Hello everyone.

I am looking for a slackbuild for mandelbulber (a program that makes 3d fractals). I attempted to make my own but discovered that it uses qmake so the syntax for passing ARCH, PREFIX, LIBDIR, etc. is unclear to me. What I *have* figured out is that qmake replaces ./configure and that it is controlled by a ".pro" file.

I attempted to find a slackbuild template for qmake usage but could not.

I searched for a mandelbulber slackbuild. I found two but they were for Vector Linux and seemed to work differently from regular slackbuilds: altered layout and they apparently download the package as well.

Thank you in advance.

It's been on my TODO list for ages...

It is always best to copy from existing SlackBuilds. Clone the SBo repository and grep for qmake:

Code:

git clone git://slackbuilds.org/slackbuilds
grep -r qmake slackbuilds/

There are dozens of them that use qmake.

And/or look at how other distros build it.
Arch has the most easily searchable repository and a reasonably understandable build format
e.g. https://aur.archlinux.org/cgit/aur.g...delbulber2-git

as a long time user of that software
i just manually build the git pull of mandelbulber2
( the build scripts are for Ubuntu and use sudo )
or use the "mandelbulber2-2.0.6" download
http://www.fractalforums.com/release...ulber-v2-2-06/

qtcreator uses the *.pro

you can READ the shell script "install" yes it is MISSING the .sh on the end

and run qmake on the *.pro
then run make and make install

as of 2.0.5 the build scripts are a bit different than the older 2.0 ones were

PS.

if you change the default install location of
"/usr/bin"
"/usr/share"
you WILL!!!! need to manually edit some default .frac files and a default config file

just search the source text to replace the instances of "/usr" with YOUR install location

How interesting, since I tried a direct compile (not a slackbuild) and that failed. Seems it can't find the qt libraries. JohnVV, I am going to guess you're on a 32 bit slackware?

Anyway, here is what I have got as a slackbuild:

Code:

#!/bin/sh

# Slackware build script for mandelbulber
# At this time, this script fails.  The problem is that the qmake
# line fails at a missing library.  Hello lib64!

# Written by PCC
# License for this slackbuild: public domain

# The way this program must be compiled is a bit different from usual.
# My usual thing of putting things in /usr/local is not being done.
# This program will be in directories off of /usr.
# I could find no way for telling it to use lib64 instead of lib so
# I did not.  Hopefully it finds the libraries that it needs anyway. EDIT:  nope

PRGNAM=mandelbulber2
VERSION=${VERSION:-2.06}
BUILD=${BUILD:-1}
TAG=${TAG:-_pcc}

if [ -z "$ARCH" ]; then
  case "$( uname -m )" in
    i?86) ARCH=i486 ;;
    arm*) ARCH=arm ;;
       *) ARCH=$( uname -m ) ;;
  esac
fi

CWD=$(pwd)
TMP=${TMP:-/dev/shm/pcc}
PKG=$TMP/package-$PRGNAM
OUTPUT=$CWD

# note: it may be that ARCH is ignored later by qmake & make
if [ "$ARCH" = "i486" ]; then
  SLKCFLAGS="-O2 -march=i486 -mtune=i686"
  LIBDIRSUFFIX=""
elif [ "$ARCH" = "i686" ]; then
  SLKCFLAGS="-O2 -march=i686 -mtune=i686"
  LIBDIRSUFFIX=""
elif [ "$ARCH" = "x86_64" ]; then
  SLKCFLAGS="-O2 -fPIC"
  LIBDIRSUFFIX="64"
else
  SLKCFLAGS="-O2"
  LIBDIRSUFFIX=""
fi

set -e

rm -rf $PKG
mkdir -p $TMP $PKG $OUTPUT
cd $TMP
rm -rf $PRGNAM-$VERSION
tar xvf $CWD/$PRGNAM-$VERSION.tar.gz
cd $PRGNAM-$VERSION

 -o -perm 440 -o -perm 400 \) -exec chmod 644 {} \;

cd makefiles
# next is where it fails: qmake doesn't get the whole lib64 thing
CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS" \
 qmake mandelbulber.pro
make all
make clean
cd ..
mv makefiles/mandelbulber2 usr/bin/mandelbulber2

# following their "install" script, instead of "make install", these
# next two lines
install -s usr/bin/mandelbulber2 $PKG/usr/bin
cp -ra usr/share/ $PKG/usr/

# put this in a doinst.sh?:  desktop-file-install mandelbulber2.desktop

mkdir -p $PKG/usr/doc/$PRGNAM-$VERSION
cp COPYING NEWS README $PKG/usr/doc/$PRGNAM-$VERSION
cat $CWD/$PRGNAM.SlackBuild > $PKG/usr/doc/$PRGNAM-$VERSION/$PRGNAM.SlackBuild

mkdir -p $PKG/install
cat $CWD/slack-desc > $PKG/install/slack-desc
#cat $CWD/doinst.sh  > $PKG/install/doinst.sh

cd $PKG
/sbin/makepkg -l y -c n $OUTPUT/$PRGNAM-$VERSION-$ARCH-$BUILD$TAG.${PKGTYPE:-tgz}

# actual end of this file

Yes, it fails, but perhaps it can be a starting point for someone?

Mandelbulber2 is based on Qt5, which could be the reason for the Qt errors - Slackware does not contain Qt5.

D'oh! Well, that explains it.

2.06 is a qt5 program

the creator is a die hard UBUNTU user

i am on a 64 bit OS with QT 4.8 and qt 5.4
