Compiling qt version SuSE (gamepad)

[jepbo]

Hello.

I have tried to compile ppsspp.

I have done the git clone to download the software. Once downloaded I have installed all the dependent libraries until running ./b.sh has compiled without problems.

I can run the compiled ppsspp and works well. But I try my gamepad, that is well mapped in the KDE joystick configuration section, but when I run ppsspp it detect my 4 buttons that should go to square, triangle, cirecle and cross to up, right, down and left, making it useless. Because KDE detects the gamepad well, I have thought that maybe the qt version of ppsspp uses well my gamepad, but when I run ./b.sh --qt I get the following error:

Does anyone know if I'm missing any library? I don't know what the

Code:

means.

Any help is welcome.

First of all the joypad handling code is 100% shared between the SDL and QT versions (which is why you need SDL for gamepad support even with the Qt version)

Secondly, when looking for the cause of the compilation failure always look at the first error, subsequent errors may just be because the compiler couldn't recover from the first error (as is the case with your log)

So the error you need to worry about is

Code:

../native/thin3d/thin3d_gl.cpp:139:18: error: expected ‘;’ at end of member declaration
  ~Thin3DGLBuffer() override {
                  ^

Either your compiler does not understand the "override" keyword or some macro is interfering with it. Try to update your compiler to a newer version

edit: quick google search reveals that you need GCC 4.7 or higher for that keyword to work (I mean if you really don't want to update for some reason and don't mind it possibly failing somewhere else you can also just remove the "override" everywhere since it's just a compile time check and does not usually change the resulting binary)

Thanks Bigpet for your answer.

I hace checked my version of g++ and is 4.8.3. I have removed many override and I have been compiling to the point that I get this error

Code:

g++ -c -pipe -Wno-unused-function -Wno-unused-variable -Wno-strict-aliasing -fno-strict-aliasing -Wno-unused-parameter -Wno-multichar -Wno-uninitialized -Wno-ignored-qualifiers -Wno-missing-field-initializers -msse2 -O3 -ffast-math -std=c++0x -Wall -W -D_REENTRANT -fPIE -DUSING_QT_UI -DUSE_FFMPEG -D_M_X64 -D_ARCH_64 -DPPSSPP_GIT_VERSION="\"v1.0.1-207-g79fc557\"" -D__STDC_CONSTANT_MACROS -Doverride -DSDL -D_REENTRANT -DQT_NO_DEBUG -DQT_OPENGL_LIB -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I../Qt -I. -I../ext/zlib -I../Common -I../ffmpeg/linux/x86_64/include -I../../ppsspp -I../Common -I../native -I../native/ext -I../native/ext/glew -I../Qt -I../Qt/Debugger -isystem /usr/include/SDL2 -isystem /usr/include/qt5 -isystem /usr/include/qt5/QtOpenGL -isystem /usr/include/qt5/QtWidgets -isystem /usr/include/qt5/QtGui -isystem /usr/include/qt5/QtCore -I.moc/ppsspp -I.ui/ppsspp -I/usr/lib64/qt5/mkspecs/linux-g++ -o .obj/ppsspp/mainwindow.o ../Qt/mainwindow.cpp

I'll try to upgrade the compiler to version 4.9 and check if it understands the override keyword.

Thanks again for your answer.

Hi!

I have upgraded the compiler and I have compiled without any problem (thanks Bigpet). Now I can run build-qt/ppsspp but the gamepad is still not well mapped. It's strange because it works well in dolphin-emu. I'll keep investigating.
