Now we can configure the ScummVM build system so it knows what backend we target and where our Raspberry Pi ''local sysroot'' is located, containing the Raspberry Pi headers and libraries the cross-compiler and linker will need. In this example configuration, we disable debug symbols since it's intended for final users. | Now we can configure the ScummVM build system so it knows what backend we target and where our Raspberry Pi ''local sysroot'' is located, containing the Raspberry Pi headers and libraries the cross-compiler and linker will need.

Remember that we have already exported the ''RPI_ROOT'' environment variable previously and updated the ''PATH'' environment variable to be preceded by the ''RPI_ROOT'' path and succeeded by the path to the Raspberry Pi toolchain bin folder (as shown in the previous steps). | Remember that we have already exported the ''RPI_ROOT'' environment variable previously and updated the ''PATH'' environment variable to be preceded by the ''RPI_ROOT'' path and succeeded by the path to the Raspberry Pi toolchain bin folder (as shown in the previous steps). | ||

A good idea is to create a ''scummvm'' folder in our ''/home/pi'' directory on the Raspian OS SD Card, and put the distribution folder contents there along with any games we want to use with it. | ||
In order to have the text-to-speech feature available for ScummVM we should also install the speech-dispatcher package and a text-to-speech engine (as per the instructions in this pertinent [https://github.com/scummvm/scummvm/pull/1808 Pull Request]) | In order to have the text-to-speech feature available for ScummVM we should also install the speech-dispatcher package and a text-to-speech engine (as per the instructions in this pertinent [https://github.com/scummvm/scummvm/pull/1808 Pull Request]) | ||

'''Note 1:''' There's a number of optional additional files that can be copied in the ScummVM directory along with the ''scummvm'' executable, which ScummVM uses for themes, GUI translations and as auxilliary data files for some of the game engines. Such list of files is shown [[HOWTO-Release#Binaries|here]]. | '''Note 1:''' There's a number of optional additional files that can be copied in the ScummVM directory along with the ''scummvm'' executable, which ScummVM uses for themes, GUI translations and as auxilliary data files for some of the game engines. Such list of files is shown [[HOWTO-Release#Binaries|here]]. These files should be already present in your distribution folder scummvmDist, if you used the "prefix" switch in configure and the make install command as shown above. | ||
'''Note 2:''' As of yet, there are some known issues with the ALSA sound driver especially in conjunction with the PulseAudio system on Raspbian OS (3.2). Having PulseAudio installed (by default it is not installed) may result to bad sound output in ScummVM (and other apps). | '''Note 2:''' As of yet, there are some known issues with the ALSA sound driver especially in conjunction with the PulseAudio system on Raspbian OS (3.2).
