Building software is not that relaxing.

Building software is not that relaxing.

 

I need a good CAD program on my mac laptop (Powerbook so no Windows emulation) and I have found my choices quite limited. As a student I want something free, legally free. Not due to not wanting to pirate software, rather there is not much software our there to pirate for what I am looking for.

Taking the advice of a TA I looked into the QCad community edition. The company releases their CAD software commercially with the binaries released under GPL. I like free open source software when available so I thought I would try it out.

I needed to build it myself, I have never done this before. I turned to my good friend Google and found this post. This gave rough instructions on how to do it and assumed a much deeper knowledge of the process then I had. I was starting from scratch. Here is what I did:

  1. I already had XCode and X11 installed on my computer from a while back so I did not need to install them. They can either be installed from the system install disks or downloaded from Apple (XCode at least).
  2. Next I downloaded and installed fink. fink is a program/terminal command that allows for easy acquisition and installation of packages.
  3. With fink I installed qt3mac by using the terminal command “fink install qt3mac” followed by the supplementary packages qt3mac-shlibs, qt3mac-apps and qt3mac-doc. These are installed by adding the “-shlibs” onto the fink install command.
  4. Next I used cd to go to the directly with QCad in it (the one that was downloaded) and set the path to qt3mac by using the command “export QMAKE=/sw/share/qt3mac” and “export QMAKESPEC=/sw/share/mkspecs/macx-g++”. This sets the correct paths for the build command of QCad.
  5. At this point I realized that I did not actually have gcc installed, I reinstalled it using the XCode installer. gcc is a C++ compiler or a collection of compilers. I think at least.
  6. There site I originally found has instructions regarding a patch but I could not figure out how to get it to work. So I skipped this.
  7. cd to the qcad directory /scripts/ and enter “./build_qcad.sh”. This will start the build of the program which should result in a nice QCad.app program to drop into your applications folder.

For me building the program failed. I think I needed the patch but since I could not apply it (alright I don’t know how) it failed. While doing all of this I found a pre-packaged version of QCad on this nice website. I think I also saw an intel version floating around somewhere, don’t know where I saw it though.

So none of this had to be done if I had just found this pre-compiled version first.

Ironically I finally opened up QCad to find out that it does not do what I need it to do.

I have installed Vectorworks 2009 instead with a student license and will try that out now. I could just break down and go use SolidWorks at one of the computer labs on campus, I just want to have a copy for me to use.

Sitting Around

 

Just hanging about.

Just hanging about.

Wound up playing cards all evening instead of doing real work like writing about installing QCad and other computer related things.

Well there is always tomorrow.
