Making libnoise on MinGW

[GrrBrr]

I was trying for several weeks now to compile libnoise on the free Windows gcc MinGW, but i failed. Does anywone know how to do that?

Hi GrrBrr,

cpinson created a new, improved makefile that hopefully will fix your problems.  It's not packaged yet, but you can use CVS to grab the latest version of libnoise.

In Linux, you'd enter the following to compile libnoise:

./bootstrap
configure
make
make install

I'm not sure how this translates to MinGW since I'm a VC++ guy.

Let me know if this helps.

I'm using the latest "Current" MinGW, set up as described at http://www.mingw.org/MinGWiki/index.php/RealDumbQuickstart

I've grabbed the latest source from CVS (Jan 9 2005) and built it, and it compiles without error.  (Note:  "./configure --prefix=/mingw --exec-prefix=/mingw", and you'll need doxygen installed and in your path in order to build and install.)

My problem is, my programs won't link against libnoise.a.

e.g.:

~/libnoise-tutorial $g++ -lnoise tutorial2.cpp
C:/Temp/ccobbaaa.o(.text+0x131):tutorial2.cpp: undefined reference to `noise::module::Perlin::Perlin()'
C:/Temp/ccobbaaa.o(.text$_ZN5noise6module6PerlinD1Ev[noise::module::Perlin::~Perlin()]+0xb):tutorial2.cpp: undefined reference to `vtable for noise::module::Perlin'
C:/Temp/ccobbaaa.o(.text$_ZN5noise6module6PerlinD1Ev[noise::module::Perlin::~Perlin()]+0x16):tutorial2.cpp: undefined reference to `noise::module::Module::~Module()'
collect2: ld returned 1 exit status

...It looks like ld is finding libnoise.a, but it can't find the symbols within it.

source so far:

#include <iostream>
#include <noise/noise.h>
using namespace noise;
int main (int argc, char** argv)
{
  module::Perlin myModule;
  return 0;
}

...Help!

Okay, responding to my own post here, I seem to have a warning halfway through building libnoise.a:

/bin/sh ../libtool --mode=link g++  -g -O2   -o libnoise.la -rpath /mingw/lib -version-info 0:0:0 latlon.lo noisegen.lo cylinder.lo line.lo plane.lo sphere.lo abs.lo add.lo billow.lo blend.lo cache.lo checkerboard.lo clamp.lo const.lo curve.lo cylinders.lo displace.lo exponent.lo invert.lo max.lo min.lo modulebase.lo multiply.lo perlin.lo power.lo ridgedmulti.lo rotatepoint.lo scalebias.lo scalepoint.lo select.lo spheres.lo terrace.lo translatepoint.lo turbulence.lo voronoi.lo 

libtool: link: warning: undefined symbols not allowed in i686-pc-mingw32 shared libraries

...then the makefile continues running ar and ranlib, etc. without errors.

I use the following makefile to compile 0.9 on mingw. It's a bit stupid but I'm no make expert. Luckily libnoise (at least 0.9) doesn't have any weird code in it so compiling it is pretty easy.

Regards,
David.

CXXFLAGS = -ansi -O3 -fno-nonansi-builtins -fno-rtti -Wall
VPATH = src;src/model;src/module

Hi David,

I don't know much about makefiles (I develop using Visual Studio project files), so do you think this would work under all UNIXes?  I know that there are several developers that are having problems with the existing makefiles.

This should work for *NIX people:

CXXFLAGS = -ansi -O3 -fno-nonansi-builtins -fno-rtti -Wall
VPATH = src src/model src/module

OBJS = latlon.o noisegen.o cylinder.o line.o plane.o sphere.o abs.o add.o billow.o blend.o cache.o checkerboard.o clamp.o const.o curve.o cylinders.o displace.o exponent.o invert.o max.o min.o modulebase.o multiply.o perlin.o power.o ridgedmulti.o rotatepoint.o scalebias.o scalepoint.o select.o spheres.o terrace.o translatepoint.o turbulence.o voronoi.o

# This target makes a static library
libnoise.a: $(OBJS)
ar cru $@ $(OBJS)
ranlib $@
