The machines officially supported for Pintos development are
the Linux machines in the labs managed by CSG, as described on
the @uref{http://www.doc.ic.ac.uk/csg/facilities/lab/workstations, ,
CSG webpage}.

The Pintos utilities can be located at @value{localpintosbindir} on CSG-run
lab machines.

Watch the commands executed during the build.
On the Linux machines, the ordinary system tools are used.

@macro localhonorcodepolicy{}
Please respect the college's plagiarism policy by refraining from reading any coursework solutions available online or elsewhere.
You must also refrain from posting any of your code or solutions publically online (such as on GitHub) or sharing them with your classmates.
Reading the source code for other operating system kernels, such as Linux or FreeBSD, is allowed,
but do not copy code from them literally.
You must cite any code that inspired your own in your design documentation.
@end macro
@macro localcredits{}
Additional modifications have been made to the documentation, code and task structure when adapting and developing the material
for use at Imperial College London by Mark Rutland, Feroz Abdul Salam, Mark Wheelhouse, Fabio Luporini and Fidelis Perkonigg.
A number of DoC students have also made valuable contributions to the ongoing development of the @code{pintos}
project@footnote{If you have suggestions for improving the @code{pintos} tasks, spot and fix a bug or contribute new material to the project, then you too could be added to the above list. If interested, please discuss with Dr Mark Wheelhouse.},
and we thank them here:
@itemize
@item Dragos Dumitrache (2015) - created the first version of the ``pintos for Mac'' guide.
@item Nandor Licker (2015) - spotted an upcoming change to QEMU in 2015 that would have interfered with the @code{pintos} shutdown code.
@item Levente Kurusa (2017) - updated the ``pintos for Mac'' guide for more recent versions of MacOS and created the Mac installation patch files.
@item Emma Gospodinova (2019) - spotted the need to add the @code{-fno-ptr} and @code{-fno-pie} flags to @code{gcc} calls in the @code{pintos} makefiles, which would otherwise lead to key parts of the user-programs code being optimised out.
@item Moritz Langenstein (2019) - identified the need for additional explicit type conversions in numerous test cases to support stronger @code{gcc} warning flags.
@item Alex Tasos (2021) - provided a linker script @code{loaderfix.ld} to fix a bug in linking the @code{pintos} loader (@code{loader.bin}) on Arch Linux systems.
@item Bartlomiej Cieslar (2021) - spotted a potential double-free in the @code{load_segment} function in @code{src/userprog/process.c}.
@item Charlie Lidbury (2021) - spotted a potential issue with setting the writable flag for overlapping pages in the @code{load_segment} function in @code{src/userprog/process.c}.

@macro localgitpolicy{}
Instead, we recommend integrating your team's changes early and often
using Git (@pxref{Git}).
This is less likely to produce surprises, because everyone can see everyone else's code as it is written, instead of just when it is finished.
Version control also makes it possible to review changes and, when a change introduces a bug, drop back to working versions of code.
