Please do not use the issue tracker to ask questions. Both of the main developers of Sigil monitor the Sigil Forum at https://www.mobileread.com/forums. All questions should be directed there.

Issue tracking is intended for discussion around issues with the code. It is also intended for actual bug tracking and for tracking feature requests.

At one point in time issue tracking was disabled because it had become unhelpful. The majority of issues where requests or abusive comments related to Sigil not running on older OS's whose own manufacturer had declared end of life.

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.

The BuildingOnLinux.md file in the docs directory contains information on building Sigil from source code (and installing it on Linux machines).

Building using purely XCode is no longer supported on Mac OS X. The easiest way to build Sigil on Mac OS X is to use cmake 3.0 and the command line.

Also because Sigil now embeds Python 3.4.X, see

 docs/Building_A_Relocatable_Python_Framework_on_MacOSX.txt

for detailed instructions on how to build a fully relocatable Python 3.4.X framework before building Sigil.

To build Sigil with your newly built relocateable Python 3.4.X framework see:

docs/Bundling_Python3_With_Sigil_on_MacOSX.txt
