config.log.



## Install from a release

Check dependencies and configure build system:

```
./configure
```

Build Rofi:

```
make
```

The actual install, execute as root (if needed):

```
make install
```


## Install a checkout from git

Generate build system:

```
autoreconf -i
```

Create a build directory:

```
mkdir build
```

Enter build directory:

```
cd build
```

Check dependencies and configure build system:

```
../configure
```

Build rofi:

```
make
```

The actual install, execute as root (if needed):

```
make install
```


## Options for configure

When you run the configure step there are several you can configure. (To see the full list type
`./configure --help` ).

The most useful one to set the installation prefix:

```
./configure --prefix=<installation path>
```

f.e.

```
./configure --prefix=/usr/
```

### Install locally

or to install locally:

```
./configure --prefix=${HOME}/.local/
```

###  I3 workaround

 If i3 is installed in a non-standard prefix, point it to the right location using:

```
CFLAGS="-I/weird/i3/path/include/" ../configure
CFLAGS="-I/weird/i3/path/include/" make
```

## Options for make

When you run make you can tweak the build process a little.

### Verbose output

Show the commands called:

```
make V=1
```

### Debug build

Compile with debug symbols and no optimization

```
make CFLAGS="-O0 -g3" clean rofi
```

### Get a backtrace

Getting a backtrace using GDB is not very handy. Because if rofi get stuck, it grabs keyboard and
mouse. So if it crashes in GDB you are stuck.
The best way to go is to enable core file. (ulimit -c unlimited in bash) then make rofi crash. You
can then load the core in GDB.

```
gdb rofi core
```

## Install distribution

### Debian or Ubuntu

```
apt-get install rofi

```
