emulationstation does not compile on lubuntu 14.04

Neo-Rio

It's not compiling properly on a 32-bit up-to-date lubuntu 14.04.
I get it that it's an older LTS release, but this is the only one that will really support most AGP graphics cards on 32-bit systems (on which I am trying to compile everything)

Here's what I see in the logs (summarized to avoid the forum spam filter)
"/usr/include/c++/4.8/bits/vector.tcc:134:5: note: no known conversion for argument 1 from candidate expects 2 arguments, 1 provided"

looks like a gcc error with 4.8

Will try adding gcc 4.9 to this version of lubuntu and report back

Neo-Rio

Nope, still not working.
The executable is now gcc 4.9, but the other libraries are using 4.8 - which seems tied to everything else in the distribution.
Hence emulationstation is still not compiling

@neo-rio Use a supported system then. Is there a reason you're not upgrading to the latest LTS ?
EDIT: I saw you mentioning the reason you're not upgrading - is you graphic card not supported in the 16.06 or latest LTS ?

@mitu

Nope. 14.04 was the last LTS that supported AGP graphics cards (think Windows XP penitum 4s circa 2004)
Without those graphics card drivers, emulationstation graphics don't render - you just get blank squares.
Hence it's fairly critical to get 14.04 working to save those old computers from landfill.

I'll have to mess with gcc some more, but 4.8 is tied to a lot of the OS.

What I've done so far is:

add-apt-repository ppa:ubuntu-toolchain-r/test
apt-get update
apt-get install gcc-4.9

which gets gcc-4.9 installed, but for some reason the compile of emulation station still uses /usr/include/c++/4.8 , so I'm missing something. I tried mucking about with update-alternatives, but the /usr/bin/gcc is already 4.9 (evidenced by gcc --help), but it still uses 4.8 libraries I guess. A bit confusing. Either way - not compiling.

Do you have a reference for this ? What cards are we talking about ?

Neo-Rio

Solved the problem. I needed both gcc and g++ to be on 4.9

(add toolchain repository to lubuntu and install gcc and g++ 4.9)
add-apt-repository ppa:ubuntu-toolchain-r/test
apt-get update
apt-get install gcc-4.9 g++-4.9

(shouldn't really need to do this bit on a fresh OS install - here for completeness)
update-alternatives --remove-all gcc
update-alternatives --remove-all g++

(update the priorities for which gcc to use)
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 10
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 20

(update the priorities for which g++ to use)
update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 10
update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9 20

(link cc and c++ to gcc and g++ - you can ignore the warnings)
update-alternatives --install /usr/bin/cc cc /usr/bin/gcc 30
update-alternatives --set cc /usr/bin/gcc
update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++ 30
update-alternatives --set cc /usr/bin/g++

(configs the default commands for gcc and g++ - you can now see the alternatives available)
update-alternatives --config gcc
update-alternatives --config g++

After this emulationstation will build properly as per instructions.

Actually, your mileage may vary by doing this when it comes to the emulators because although they all compiled, some of them crashed when executed.

Much better to use the latest 16.04 LTS or later on a PC with a CPU with core2duo or later.
