Nathan,
Thanks for that catch. Sorry... that was a mixup in my copy and paste.
They're actually both now "planetforge.node".
Actually, I think I found the issue. But, I'm not entirely sure. I
ran sudo /sbin/ldconfig -- but only after uninstalling node and building it
from source, then switching the project to a node-gyp builder.
But, both node-gyp and node-waf work. And, for anyone else who might need
help, here are the two files:
wscript:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
def set_options(opt):
opt.tool_options("compiler_cxx")
def configure(conf):
conf.check_tool("compiler_cxx")
conf.check_tool("node_addon")
conf.check_cfg(package='libpng', args='--cflags --libs',
atleast_version="1.5.0", uselib_store='LIBPNG', mandatory=True)
def build(bld):
obj = bld.new_task_gen("cxx", "shlib", "node_addon")
obj.uselib = ['LIBPNG']
obj.cxxflags = ["-g", "-D_FILE_OFFSET_BITS=64", "-D_LARGEFILE_SOURCE",
"-Wall"]
obj.target = "planetforge"
obj.source = "planetforge.cc"
obj.includes = "/usr/local/include/libpng15"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
And, planetforge.gyp:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
{
'link_settings': {
'library_dirs': [
'/usr/lib',
],
},
'targets': [
{
'target_name': 'planetforge',
'type': '<(library)',
'cflags': ['-fPIC', '-Wall'],
'libraries': ['-lpng'],
'sources': [ 'planetforge.cc' ]
}
]
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
