Hi,
I'm trying to build a module with node-waf, and it's not seeing
libpng. I started with the default ubuntu libpng12, then downloaded
and compiled and installed libpng15. Neither work. I've been running
around in circles trying to reconfigure wscript, but nada. My wscript
looks like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
import Options
from os import unlink, symlink, popen
from os.path import exists
srcdir = "."
blddir = "build"
VERSION = "0.0.1"
def set_options(opt):
opt.tool_options("compiler_cxx")
def configure(conf):
conf.check_tool("compiler_cxx")
conf.check_tool("node_addon")
conf.check(lib='png', libpath=['/lib', '/usr/lib', '/usr/local/lib',
'/usr/local/libpng/lib', '/home/straley/downloads/libpng-1.5.9'])
def build(bld):
obj = bld.new_task_gen("cxx", "shlib", "node_addon")
obj.target = "forge"
obj.source = "forge.cc"
obj.uselib = "PNG"
obj.cxxflags = ["-D_FILE_OFFSET_BITS=64", "-D_LARGEFILE_SOURCE"]
def shutdown():
if Options.commands['clean']:
if exists('planetforge.node'): unlink('planetforge.node')
if exists('build/Release/planetforge.node') and not
exists('planetforge.node'):
symlink('build/Release/planetforge.node', 'planetforge.node')
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
when I run node-waf configure, I get:
Checking for program g++ or c++ : /usr/bin/g++
Checking for program cpp : /usr/bin/cpp
Checking for program ar : /usr/bin/ar

Checking for library png : not found
With the -vvv option, the snippet near the "library png" line, looks
like:

Running libpng-config with the following flags, yields me:
--prefix : /usr/local
--libdir: /usr/local
--libs: -lpng15
--cflags: -I/usr/local/include/libpng15
--I_opts: -I/usr/local/include/libpng15
--L_opts: -L/usr/local/lib
--ldflags: -L/usr/local/lib -lpng15
/usr/local/include/libpng15 has:
-rw-r--r-- 1 root root 115248 Feb 29 10:16 png.h
-rw-r--r-- 1 root root 21354 Feb 29 10:16 pngconf.h
-rw-r--r-- 1 root root 6033 Feb 29 10:16 pnglibconf.h

libpng15.so.15.9.0
-rwxr-xr-x 1 root root 601026 Feb 29 10:16 libpng15.so.15.9.0
And, in my forge.cc file, I'm attempting to include libpng with:
#include <png.h>
So... I think that's all the relevant info. If anyone has any ideas,
I'd greatly appreciate it. I've been chasing ghosts for two days on
this.
Thanks,
Scott
