Hi,
I've gotten a little further. This will now configure and compile, but I'm
getting an error "Error: Unable to load shared
library /node/site/src/forge/build/Release/forge.node". Here's my new
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')
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.source = "hello.cc"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
