====== Building Petrify ======

  - Build 32-bit SIS static libraries (see [[devel:dependency:sis|instruction]]) and put them into ''sis/lib'' directory:
    * ''libsis32.a'' -- 32-bit Linux build, ''gcc -m32'' toolchain
    * ''libsis32osx.a'' -- 32-bit Mac OS X build, ''mp-gcc5 -m32'' toolchain
    * ''libsis32win.a'' - 32-bit Windows build, ''i686-w64-mingw32-gcc'' toolchain
  - Define the target operating system at the beginning of ''Makefile'':
    * ''OS = win'' -- Windows
    * ''OS = osx'' -- Mac OS X
    * ''OS = '' -- Linux
  - Rebuild Petrify:<code>
make clean  # optional
make
</code>

<WRAP important round>
While 64-bit versions of Petrify can also be built, only the Linux 64-bit version is stable. If you decide to build a 64-bit version, then put ''libsis64.a'' of SIS library in ''sis'' directory and set ''ARCH=64'' variable in the ''Makefile''.
