Netsurf Framebuffer

[tomas_em]

Hi,

I try to compile Netsurf browser from source with Framebuffer support from the source. I sucessfully compiled the 2.8 version, got nsfb binary, but it does not work. When I run them in verbose mode, then I get some error mesages about framebuffer and then he returns back to commandline.

BTW: I tried the SCUMMVM emulator in framebuffer and it works (just I have to to lower the resolution first to 960*576), so I think, that framebuffer is working correctly.

Any ideas?

Hello,

first - you should build version 2.9 - besides several improvements, the 2.8 has an non-functional linux framebuffer implementation. ( kernel framebuffer )

So, checkout 2.9

If you still have problems, please post the complete verbose log.

Thanks.

Did you finally manage to compile it?

I get this compilation error (on 2.9, make TARGET=framebuffer):

In file included from build-Linux-framebuffer/caret_image.c:16:
./framebuffer/fbtk.h:57: error: expected specifier-qualifier-list before ‘nsfb_event_t’

I also tried $links2 -g with links2 from the debian repos, and I get pink stripes and killing links2 doesn't remove them (need to reboot to get back my screen).

Do you have any clue (for links2 or netsurf?)

Did you finally manage to compile it?

I never tried to compile it for rasperry pi - I don't even have one. I just compile netsurf for the Atari OS FreeMiNT.

About your errors:

Did you install libnsfb properly? What does pkconfig output for the libnsfb includes?

Please compile and install libnsfb first. It looks like some struct isn't declared - which probably only happens when you did not compiled/installed libnsfb.

Edit:
make sure that you install the libnsfb that comes with release 2.9. There where some significant changes, so maybe some structs have changed or where added.

Please read the document BUILDING-Framebuffer within the docs directory.

I did "make TARGET=framebuffer' in the root directory, and I see it is intended to compile libnsfb which is included. I also installed the dependencies described in the doc.

Still, i went to the libnsfd directory and tried to compile it and got:

COMPILE: src/plot/api.c
cc1: warnings being treated as errors
src/plot/api.c: In function ‘nsfb_plot_copy’:
src/plot/api.c:151: error: cast increases required alignment of target type
src/plot/api.c:162: error: cast increases required alignment of target type

Why are the warnings treated as errors?

Why are the warnings treated as errors?

-Werror ?

These warnings are platform-specific... they should not happen, but now you have to deal with it.
I think the easiest solution is to remove the -Werror flag from the libnsfb build.
