Note that currently Sigil only provides binaries that work for Windows x86 and x64 and will only run on Vista or newer releases. Mac OS X binaries are typically 1 version behind the current release. This means that today 10.10 is the current release so it should run on the 10.9 (with the latest updates installed). However, this is subject to change and this information is not always current. Especially for OS X. This is an at best support for older versions of Windows and OS X.
All releases also have CHECKSUM.sha256 file which includes sha256 check sums of the file posted. This will let you know if you have a bad download or if a build has been tampered with.
Going forward release announcements will include the sha256 checksum of the checksum file itself so you can verify that it hasn’t been tampered with either.
Finally, the OS X .app file (not the .dmg) is signed before release. You can use the code sign command line tool (I don’t know of another way) to verify the application. There will be a lot of output but you’re looking for my signature saying I (Kevin, the project maintainer built this binary). From a terminal run:
codesign -dvvv Sigil.app
There will be a lot of output but you should look for the following: Authority=Developer ID Application: Kevin Hendricks (2SMCVQU3CJ)
Sigil’s source code can be found on GitHub. Sigil is open source and licensed under the GPLv3. We’re very opens to contributions and that’s how the project keeps itself running. Feel free to discuss ideas using the issue tracker before issuing pull requests.
The issue tracker is for development issues that are actively being worked. It is not a user support system. It is meant solely for development and for developer to developer communication. If you need help then head over to the Support Page.
Feature requests opened on the issue tracker will be closed if there isn’t anyone willing to implement the requested feature. Only items being worked will be left open.
Sigil On Linux
Sigil will run on Linux. We try to maintain compatibility with Linux mainly because it’s easy to with Sigil supporting both OS X and Windows and it uses a number of technologies that already support Linux. That said, there is currently no official Sigil binary package for Linux.
If you’re looking to use Sigil on Linux, you can always build it from source. The docs directory in Sigil’s Github repository has instructions that can guide you in that endeavor. You can also look to see if Sigil is available in the official repositories for your flavor of Linux.
