Hi I''m using princexml pdf generation in one of our apps and bump into this very weird problem. On our ubuntu box and local machines (MacBook Pro) pdfs are generated flawlessly. On the production xserve (running the rails app in production mode on a mongrel cluster), a 2.8 GHz Quad-Core Intel Xeon, strange things start happening. The following sections give back nil values in

Let''s try that again, without Hotmail''s crappy formatting. Dan, I am one of the developer of the FreeRIDE project (the Ruby IDE) and I''m in charge of the FreeRIDE debugger with which we have had a number of problems on Windows now mostly due to the clunky implementation of IO/Process/Signal stuff on Win32. I recently came across your Win32 utils package and

Example one, login 1 works just fine. def login1 @driver.Login(username, password) end However, if I try to pass "Login" to the driver as an argument (example two Login 2), I get "undefined method `command_string'' for #<SOAP::RPC::Driver:0x316dc28>" "Login" is a legit

I''ve got a client who''s recently been moved onto a CentOS4 machine from a 3.x and is writing: "It looks like there''s one remaining problem now; at several points in the PHP part of the dating software, C- binaries are called using popen(). The binaries work correct (tested at the command line with the proper arguments) The popen() retrieves the correct command

I''m running Apache2 on windows and I have a controller that issues a popen. class FileController < ApplicationController def index f = IO.popen("dir") @files = f.readlines end end This works using webbrick but on Apache produces... ---------- Errno::ENOENT in File#index No such file or directory - dir RAILS_ROOT: C:/www/teensymud/public/../config/..

Hi, My application uses popen to execute UNIX commands. After I replace rsh with ssh, it stopped working. I have made a test C code to reproduce the problem as attached in this email. In the test program, I called popen for ssh command and then pclose right away. I got the following error: kirk 588$ a.out Write failed flushing stdout buffer. write stdout: Broken pipe Any idea what is

As described on wkhtmltopdf Google group (http://code.google.com/p/wkhtmltopdf/issues/detail?id=162), I have a problem generating a PDF while using popen and wkhtmltopdf. wkhtmltopdf takes HTML code as input and ouputs a PDF file.

I''m looking to write a javascript heavy clientside program with a something serverside backend that connects to the free maxima math program. I have extensive knowledge of ruby on rails, so I would prefer to call Maxima with ruby, but I don''t know if this is even possible. Its fairly easy to call Maxima (with a lisp implementation) using ANSI C, it is a little less easy to

Dear all, When I compared the performance of some application on both a Xen domU and a standard linux machine (where domU runs on a similar physical mahine), I notice the application runs faster on the domU than on the physical machine. Instrumenting the application code shows the application spends more time on popen() calls on domU than on the physical machine. I wonder if xenlinux does some

Hi all, I am encountering the following crash-causing bug using popen on occasion. I haven''t been able to narrow it down yet, but I am curious if anyone else has seen it or may have more information for me: Workers::DviToPng::PipeProtocol > terminate called after throwing an instance of ''std::runtime_error'' > what(): unable to reap subprocess > Abort trap
