<gediz0x539> insep_: yep, fb stride. thanks!
<gediz0x539> i've enabled internal frame buffer but somehow it overflows
<gediz0x539> if i change x,y pos of layer or change stride value, it moves but still only a limited part of the layer is drawn

<sunshavi> any experience compiling libgccjit?. I have this issue https://termbin.com/h62m
<pmp-p> why /lib/cpp instead /usr/bin/cpp ?
<sunshavi> configure script is detecting it that way
<pmp-p> maybe try CXX=/usr/bin/cpp ./configure
<sunshavi> configure guess is not detecting the correct float-abi. configure detects soft and it should be hard
<sunshavi> check line 222
<pmp-p> but thats cflags
<pmp-p> not cxx
<pmp-p> try adding ac_cv_env_CXXFLAGS_set=
<sunshavi> this is the complete PKGBUILD https://termbin.com/9nzc4
<sunshavi> error happens after 4h of compilation
ganbold_ has quit [Ping timeout: 240 seconds]
<pmp-p> as always :p
<pmp-p> i'd set both CXX= and CXXFLAGS=
<pmp-p> /lib/cpp is obviously wrong, and even if it was right, it could maybe not care about CFLAGS
<pmp-p> so maybe gain 4h :p
<sunshavi> ok. But problem happens just on that directory
<sunshavi> i am going to try to run it manually
<hramrach> it's CPP, not CXX
<hramrach> with most buildsystems
<hramrach> CXX is c++ without using special characters
<pmp-p> CPP is c preprocessor for me
<hramrach> yes, and that's what /lib/cpp or /usr/bin/cpp is
<hramrach> pmp-p | maybe try CXX=/usr/bin/cpp ./configure
<sunshavi> could I just do a symlink from /bin/cpp to /lib/cpp?
<pmp-p> oops indeed CPP it is
<pmp-p> sunshavi: it should be $(CC) -E i guess and all the passed flags
<sunshavi> after the symlink compilation is moving forward again
<pmp-p> i hope the -isystem will be ok
<pmp-p> well i don't know what is -V :p
<sunshavi> hramrach: pmp-p: thanks. crossing fingers and waiting another hour
<pmp-p> sunshavi: it's trying to look in /usr/include/gnu so the sysroot is probably wrong
<pmp-p> and i don't see the sysroot param in the log
tnovotny has quit [Quit: Leaving]
<sunshavi> '/lib/cpp' how the configure script has been hinted about that path. binaries are on /bin or /usr/bin
<pmp-p> /usr/lib/cpp is valid too
<pmp-p> sunshavi: is your host gcc 10.2.0 too ?
<asdf28> hramrach: what's that USB device?
<sunshavi> pmp-p: yes it is
<hramrach> asdf28: cp2102 with reprogrammed product strings
<asdf28> is that one of these devices that you plug onto the GPIO port?

<sunshavi> compilation ended. But using the library is getting me an error
merbanan has joined #linux-sunxi
<sunshavi> the program is this one: https://termbin.com/kytm
<pmp-p> i think you need to pass same float and neon of your earlier CFLAGS
<sunshavi> ok. doing that. reporting back in 4h

<Pinchiukas> As I understand my Ditter U20 device should probably have some sort of recovery partition?
<Pinchiukas> I want to make a backup if I ever decide to go back to Android.

<matteo_> does anybody have information about hwatI can expect from an S3 or V3s if I wanted to write a full screen UI application?
<matteo_> not necessarily X11, it's a full screen UI for a device, so I don't need windowing
<matteo_> would using QT on the framebuffer be a good choice?
asdf28 has quit [Ping timeout: 256 seconds]
<matteo_> could I expect it to be reasonably smooth?
<hramrach> is that single core A7 SoC?
<hramrach> without cpufreq and theremal sensor so probably not even running at the full spped?
<hramrach> and what do you want to control with that UI?
<matteo_> yes, it's the A7
<matteo_> it's something like a 3D printer, why?
<matteo_> I would expect the driving of the device to be not a problem at all for the SoC
<matteo_> but maybe the UI would be? It seems there would be no HW acceleration for 2D at all, right?
