| 1 | Installing Survex on Unix |
|---|
| 2 | ========================= |
|---|
| 3 | |
|---|
| 4 | If you are using Debian Linux or Ubuntu Linux or a distribution based |
|---|
| 5 | on one of these, you will find it easier to install one of the |
|---|
| 6 | prepackaged versions of Survex. |
|---|
| 7 | |
|---|
| 8 | Otherwise you'll need to build from source. These instructions assume you're |
|---|
| 9 | building from released tar archive - if you want to build from by checking out |
|---|
| 10 | code from the git repository then you'll need additional tools installed, |
|---|
| 11 | documented at: https://survex.com/cvs.html |
|---|
| 12 | |
|---|
| 13 | First of all, you need to make sure you have the required libraries installed. |
|---|
| 14 | Where possible it's usually easier to install these using your Linux |
|---|
| 15 | distribution's package manager. |
|---|
| 16 | |
|---|
| 17 | Note that C/C++ library packages are usually split into runtime and |
|---|
| 18 | development, usually with similar names but with a -dev or -devel or similar |
|---|
| 19 | suffix on the development one. You'll need both installed to build Survex, |
|---|
| 20 | but typically installing the development package will automatically install |
|---|
| 21 | the corresponding runtime package too. |
|---|
| 22 | |
|---|
| 23 | * The main dependency is wxWidgets 3.2 or later - if there's a suitable |
|---|
| 24 | wxWidgets package for your platform, then just use that. |
|---|
| 25 | |
|---|
| 26 | Otherwise download the source code from https://wxwidgets.org/ and |
|---|
| 27 | follow their build instructions. IMPORTANT: You must enable OpenGL |
|---|
| 28 | support by adding --with-opengl to the configure command line. |
|---|
| 29 | |
|---|
| 30 | The last release to support wxWidgets 3.0 was Survex 1.4.17. |
|---|
| 31 | |
|---|
| 32 | * You'll also need a working C and C++ compiler (with support for C99 and |
|---|
| 33 | C++11), and also the OpenGL development libraries if these aren't pulled in |
|---|
| 34 | by installing wxWidgets. |
|---|
| 35 | |
|---|
| 36 | * Version 7.2.0 or later of the PROJ library is needed for coordinate |
|---|
| 37 | conversion functionality. |
|---|
| 38 | |
|---|
| 39 | * Optionally, GDAL is used to support reading geodata files. If not available |
|---|
| 40 | this feature is disabled. |
|---|
| 41 | |
|---|
| 42 | * Optionally, FFmpeg is used if available to implement Aven's movie export |
|---|
| 43 | feature. You need libavcodec >= 57, which seems to correspond to FFmpeg |
|---|
| 44 | >= 3.2. |
|---|
| 45 | |
|---|
| 46 | Then at a shell prompt, unpack the source code, cd into the directory, and |
|---|
| 47 | enter the following commands: |
|---|
| 48 | |
|---|
| 49 | ./configure |
|---|
| 50 | make |
|---|
| 51 | make install |
|---|
| 52 | |
|---|
| 53 | By default 'make install' will try to install Survex under /usr/local, |
|---|
| 54 | which means you'll probably need to become root for the 'make install' stage. |
|---|
| 55 | If you use sudo to manage root access, then: |
|---|
| 56 | |
|---|
| 57 | sudo make install |
|---|
| 58 | |
|---|
| 59 | You can tell configure to install Survex elsewhere (e.g. under your home |
|---|
| 60 | directory) like so: |
|---|
| 61 | |
|---|
| 62 | ./configure --prefix=/home/olly/survex |
|---|
| 63 | make |
|---|
| 64 | make install |
|---|
| 65 | |
|---|
| 66 | If your wxWidgets installation isn't picked up automatically, or you |
|---|
| 67 | have more than one version installed and want to select a particular |
|---|
| 68 | one, then you can specify this like so: |
|---|
| 69 | |
|---|
| 70 | ./configure WX_CONFIG=/opt/bin/wx-config |
|---|
| 71 | |
|---|
| 72 | You can use both --prefix and WX_CONFIG= if necessary. |
|---|
