How to compile freetype-32 in openSUSE-64?

Question

linux

I installed quartus web 13.1 on my opensuse 42.2. Together with him modelsim.
however, modelsim refused to start.

Error in startup script:
Initialization problem, exiting.
Initialization problem, exiting.
Initialization problem, exiting.
    while executing
"EnvHistory::Reset"
    (procedure "PropertiesInit" line 3)
    invoked from within
"PropertiesInit"
    invoked from within
"ncFyP12 -+"
    (file "/opt/altera/13.1/modelsim_ase/linuxallo/vsim" line 1)
** Fatal: Read failure in vlm process (0,0)

Here is the same problem

and the solution is referenced here:

sudo apt-get install libc6-dev-i386
sudo apt-get build-dep -a i386 libfreetype6
wget http://download.savannah.gnu.org/releases/freetype/freetype-2.4.12.tar.bz2
tar -xjvf freetype-2.4.12.tar.bz2
cd freetype-2.4.12
./configure --build=i686-pc-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"
make -j8

Can you please explain what it does in these scripts and how to convert them to openSUSE?
