/tmp/yaourt-tmp-aak/aur-dolphin-emu/src/dolphin-emu-3.0-build/Externals/wxWidgets3/include/wx/filefn.h:476:9: error: zero width for bit-field ‘wxAssert_477::BadFileSizeType’

wxCOMPILE_TIME_ASSERT( sizeof(off_t) == sizeof(wxLongLong_t), BadFileSizeType );

The error doesn't even line up with the file...

Ah it does when I load it through browse, god I hate google code file search.

476: wxCOMPILE_TIME_ASSERT( sizeof(off_t) == sizeof(wxLongLong_t),
BadFileSizeType );

Basically wxLongLong_t should be the same size as off_t... I wish you could print the sizes at that point...

How would I attempt to go about it? And what would the sizes give us? Or is it to see what is different?

comment the line(s) out, does everything work? haha.

Compiling right now, and it appears that I got past the point that it failed at. We'll see if the compilation is a success.

Shows a deeper problem in wx source really :\ Something on your system doesn't match the expected values for longs and pointers

p.s. id be surprised if when it compiles it actually runs without crashing :D

You should be - it compiled perfectly & I'm testing a game on it right now. Many thanks. Who would've known commenting out a line or two of code would fix it.

Weird.. it shouldn't work really. O well... haha

We might need you to work out what the appropriate fix is...

andreik7 should post the values of sizeof(off_t) and sizeof(wxLongLong_t) from that file.

How would I go about finding the values? I've only found variables with not definite value.

in that same file where you commented the line:

at line 519 right after:
#endif // platforms
add:
template struct Wow;
Wow<sizeof(off_t)> wow;

Compile, you should see some error like:
error: aggregate ‘Wow<8> wow’ has incomplete type and cannot be defined
The number inside the <> is what we want to know for off_t

SECOND!

Same thing again
This time instead of off_t we want wxLongLong_t

so replace above with:

template struct Wow;
Wow<sizeof(wxLongLong_t)> wow;

compile again and get us that other number. thanks :)

Here it is:

first change,

/tmp/src/dolphin-emu-build/Externals/wxWidgets3/include/wx/filefn.h:476:9: error: zero width for bit-field ‘wxAssert_477::BadFileSizeType’
/tmp/src/dolphin-emu-build/Externals/wxWidgets3/include/wx/filefn.h:517:20: error: aggregate ‘Wow<4> wow’ has incomplete type and cannot be defined

second change,

/tmp/src/dolphin-emu-build/Externals/wxWidgets3/include/wx/filefn.h:476:9: error: zero width for bit-field ‘wxAssert_477::BadFileSizeType’
/tmp/src/dolphin-emu-build/Externals/wxWidgets3/include/wx/filefn.h:517:27: error: aggregate ‘Wow<8> wow’ has incomplete type and cannot be defined

In short, the first vlue is 4 and the second value is 8.

sizeof(off_t)=4
sizeof(wxLongLong_t)=8

Oh dear.

template struct Wow;
Wow<sizeof(long)> wow;

template struct Wow;
Wow<sizeof(char*)> wow;

Can you try those two please?

The only difference between the two logs is this:

first change,
/tmp/src/dolphin-emu-build/Externals/wxWidgets3/include/wx/filefn.h:517:19: error: aggregate ‘Wow<4> wow’ has incomplete type and cannot be defined

second change,
/tmp/src/dolphin-emu-build/Externals/wxWidgets3/include/wx/filefn.h:517:20: error: aggregate ‘Wow<4> wow’ has incomplete type and cannot be defined

You did the long and char* seperately right? i.e. two seperate compiles. At no time were Wow<sizeof(long)> wow; and Wow<sizeof(char*)> wow; both in the file?

The same thing as previous but more detail:

So yes I did them seperately

Thank you for testing for us. I really don't have a solution other than the first one I offered which is to disabled the assert... Please let us know if you come across any crashes while using the GUI? That you can reproduce etc.

Well to be frank with you guys the only system I've really had trouble building on is this one. I'm running on a Dell Latitude D630 with a nvidia nvs 135m graphics and a Core2Duo T9300 cpu @ 2.50 ghz. Commenting those lines out allowed me to create a package for generic i686 architectures. Using the binaries I created from the altered source I tested them on a buddies i686 with slow emulation speeds but I didn't expect anything more on a netbook.

My system on the other hand I've been able to test a few gc games successfully (I don't have too high of a demand), and Super Smash Bros Melee ran just fine, if not perfect, at 45-60 fps and 80 - 100 % emulation speed depending on the map in Smash Bros.

I had everything crashing when trying to launch the game from the GUI before, but after flushing out my ram (I had like 2.90/2.96 gb used) I was able to run with no problems.

I know this system isn't much but I knew I would only try some GC games, and Super Smash Bros Melee is a fond memory of my childhood. I have a buddy of mine who's going on a long planeride with me (12+ hours), so I wanted to surprise him with the game on this laptop that I primarily use for work related java stuff.

I appreciate all you help. I created a little .diff file that comments those lines out, but I don't think you guys like that fix for everyone else. I asked other people who use this distribution of linux to try building this package on an i686 if they have spare time to see if they run into the same error and to see if the same fix that worked for me would work for them.

I'll post back, and I'll definately check back here more often to see what you guys have going on.

The problem is that off_t is not 8bytes at this point in the code. This shouldn't be an issue as we define http://code.google.com/p/dolphin-emu/source/browse/CMakeLists.txt#570 . Not sure why it's only a problem on this system...

Actually i have this very problem myself, running an arch box, updated and pulled the latest changes and still this doesnt work...
Guess i'll comment the line out and see if still doesnt compile

I think my branch will fix this problem, but I need someone to confirm it for me:

repo: https://code.google.com/r/dtittle-dolphin-emu/
branch: updated-wxWidgets

checking that out for you

Gave me similar issues.

You are missing gtk? o_O

We should check for that in the wxwidgets CMakeLists.txt, I guess.

libgtk2.0-dev I think?

Fixed it via CLI build command:

mkdir BuildCLI && cd BuildCLI
cmake -Dbindir=../Binary/Linux -Ddatadir=../Binary/Linux -DDISABLE_WX=ON ..

libgtk-x11-2.0 I think.

Well, i ended up testing that branch and it needed a greater version of wxwidgets (arch's version of the package is 2.8.12) and compilation failed again...

What failed? The branch should download version 2.9.4 or greater...

Do you have build output?

My bad, here it is.
It fails building wxwidgets

It looks like Make wants you to use the -j1 option (for one processor core) while building wxWidgets.

Open the master CMakeLists.txt file, and change line 570 to add -j1 to the make command:
BUILD_COMMAND make -j1 > ${wxWidgets_PREFIX}/wxWidgets-build.out

See if that works.

Pretty much the same thing, wxwidgets stops compiling when this happen:

Attached the error log (shorter version) from this time

Hmm... Maybe this is a problem building wxWidgets on your system?

Try going to the Externals/wxWidgets/src/wxWidgets/ directory and configure/make:

./configure --disable-shared
make

Same error:

cd ./src/stc && ./gen_iface.py
File "./gen_iface.py", line 801
print '***** Unknown line type: ', line
^
SyntaxError: invalid syntax
make: *** [include/wx/stc/stc.h] Error 1

You must have Python 3 installed. "./gen_iface.py" is formatted for Python 2.

If you set Python 2 as your default, it will fix the problem.

Changed the shebang line to python2 and it worked!

Great! I'm going to merge that branch with my master, then.

Github has "pull request" but I don't know if there is something equivalent in Google Code. Consider this a "pull request" :)

You should, finally it compiled!
I installed wxwidgets manually (f*ck compatibility) and it compiled...
I'm gonna try to do this on master branch
