| 58 | Please make sure to install the corresponding development packages in case that |
| 59 | you want to build nsxiv on a distribution with separate runtime and development |
| 60 | packages (e.g. \*-dev on Debian). |
| 61 | |
| 62 | |
| 63 | Building |
| 64 | -------- |
| 65 | |
| 66 | nsxiv is built using the commands: |
| 67 | |
| 68 | $ make |
| 69 | |
| 70 | Running make will automatically detect if libexif and libgif are available and |
| 71 | enable them if so. CLI arguments will override any automatic detection. |
| 72 | For example: |
| 73 | |
| 74 | $ make HAVE_LIBGIF=0 |
| 75 | |
| 76 | will always disable libgif. |
| 77 | Alternatively, they can be disabled via editing `config.mk`. |
| 78 | |
| 79 | Installing nsxiv: |
| 80 | |
| 81 | # make install |
| 82 | |
| 83 | Installing desktop entry: |
| 84 | |
| 85 | # make desktop |
| 86 | |
| 87 | Installing icons: |
| 88 | |
| 89 | # make icon |
| 90 | |
| 91 | Please note, that these requires root privileges. |
| 92 | By default, nsxiv is installed using the prefix `/usr/local`, so the full path |
| 93 | of the executable will be `/usr/local/bin/nsxiv`, the `.desktop` entry will be |
| 94 | `/usr/local/share/applications/nsxiv.desktop` and the icon path will be |
| 95 | `/usr/local/share/icons/hicolor/{size}/apps/nsxiv.png`. |
| 96 | |
| 97 | You can install nsxiv into a directory of your choice by changing this command to: |
| 98 | |
| 99 | $ make PREFIX="/your/dir" install |
| 100 | |
| 101 | Example scripts are installed using `DOCPREFIX` which defaults to |
| 102 | `/usr/local/share/doc/nsxiv`. You can change `DOCPREFIX` the same way you can |
| 103 | change `PREFIX` shown above. |
| 104 | |
| 105 | The build-time specific settings of nsxiv can be found in the file *config.h*. |
| 106 | Please check and change them, so that they fit your needs. |
| 107 | If the file *config.h* does not already exist, then you have to create it with |
| 108 | the following command: |
| 109 | |
| 110 | $ make config.h |
| 111 | |
| 112 | |
