Run Script Build Phase & Linking

Hi,
I have a project which links *every* *single* *time* I choose "Build
& Run" regardless of if I have made changes or not. I have tracked
down the cause of the excessive linking to a Run Script build phase
which takes one input file and one output file. The script is ran
EVERY TIME even though the output file has a newer modification date
then the input file. As I understand it XCode should not be doing
this. Is this a known bug or am I doing something wrong? Any help
would be appreciated.
Here is the ruby script:
def update_library(source_file, dest_file)
name = File.basename(source_file)
# print "Base name: #{name}\n"
# if source file doesn't exist return an error
if (!File.exists?(source_file))
print "Error: #{source_file} doesn't exist"
return 1
end
# see if we need to update
if (!File.exists?(dest_file))
# ranlib file doesn't exist
needs_update = true
print "#{name} needs to be copied...\n"
elsif (File.stat(source_file).mtime != File.stat(dest_file).mtime)
# ranlib
needs_update = true
print "#{name} needs to be updated...\n"
print "removing #{dest_file}\n"
File.delete(dest_file)
else
print "#{name} is up to date\n"
needs_update = false
end
# update library into build directory
if (needs_update)
print "copying #{source_file}\n"
system("cp '#{source_file}' '#{dest_file}'")
print "running ranlib on #{dest_file}\n"
system("ranlib '#{dest_file}'")
source_atime = File.atime(source_file)
source_mtime = File.mtime(source_file)
File.utime(source_atime, source_mtime+1, dest_file)
end
return 0
end
error = 0
num_files = ENV['SCRIPT_INPUT_FILE_COUNT'].to_i
# print "#{num_files}\n"
num_files.times do |i|
source_file = ENV['SCRIPT_INPUT_FILE_' + i.to_s]
dest_file = ENV['SCRIPT_OUTPUT_FILE_' + i.to_s]
# print "Updating #{source_file} to #{dest_file}\n"
if (error == 0)
error = update_library(source_file, dest_file)
end
end
exit(error)
