Skiasharp: Mac build does not work

[gentledepp]

Hi!
I admittedly am new to Mac OS, but I setup a build environment for SkiaSharp and I get a quite meaningless exception when running
sudo ./bootstrapper.sh -t externals-android

the relevant trace part is

[33/755] CC obj/third_party/externals/libwebp/src/dsp/libwebp_dsp.upsampling.o

[gentledepp]

by looking a bit into it as no-one is answering, the only real problem seems to be

../../../../src/c/xamarin/sk_x_path.cpp -o obj/src/c/xamarin/core.sk_x_path.o
../../../../src/c/xamarin/sk_x_path.cpp:94:38: error: comparison between 'enum SkPath::Verb' and 'enum sk_path_verb_t' [-Werror=enum-compare]
static_assert (SkPath::kMove_Verb == MOVE_PATH_VERB, "ABI changed, you must write a enumeration mapper for SkPath::Verb to sk_path_verb_t");

But I neither know how to fix it, nor where...

[hypeartist]

2 gentledepp

skia/src/c/xamarin/sk_x_path.cpp

Simply comment out lines from 93 to 101 (there are nothing extra important - just assertions)

[gentledepp]

Thank you @hypeartist, but unfortunately this only yields other similar errors.
I guess this is because the build runs with the option "treat warnings as errors"

I would much rather run the build without "warnings as errors" instead of modifying skia code...
Can you give me a hint how I could to that?

native-builds/libSkiaSharp_android/jni/SkiaSharp.mk

At line 35 try to remove -Werror switch

[gentledepp]

Thank you so much! I tried it and it did not work either.
So I switched back to your first proposal *commenting out the static asserts
and in the same file,

skia/src/c/xamarin/sk_x_path.cpp
commented out the lines 127... 130 like so

`
//#if __cplusplus >= 199711L
//static_assert (SkPath::kAppend_AddPathMode == APPEND_ADD_MODE, "ABI changed, you must write a enumeration mapper for SkPath::AddPathMode to sk_path_add_mode_t");
//static_assert (SkPath::kExtend_AddPathMode == EXTEND_ADD_MODE, "ABI changed, you must write a enumeration mapper for SkPath::AddPathMode to sk_path_add_mode_t");
//#endif

not the build seems to work

Thank you so much!

[gentledepp]

Oh man... there is still a problem, whereby a different one.

so during the libsSkiaSharp_android ndk-build, it cannot find some ?? file, but does not tell me which one.
I guess it misses some SDK?
I installed
xamarin, python 2.7.x, Xcode and git
am I missing something?

Take a look:

externals-android

[gentledepp]

I guess you mean
https://github.com/mono/SkiaSharp/blob/master/build.cake
;-)

[hypeartist]

2 gentledepp

yep!

[gentledepp]

seems I was missing ninja build system.... veeeeery interesting stuff.... never heard of it

now I ran the skia build first - as the "libs" folder mentioned in the build.cake of SkiaSharp does not exist on my system.

But the command

ninja -C out/Debug dm
out/Debug/dm

yields another 2 errors....
I'm fed up. Thank you for helping me out, but this is too tedious for me to continue. I guess SkiaSharp is still pretty Alpha-ish :-|

[migueldeicaza]

I pushed a fix that should address the static_assert errors.

I'm fed up. Thank you for helping me out, but this is too tedious for me to continue.

Totally agreed! Tried to build it on Windows with no success. That incredible building system (with all those cakes, cmakes, ninjas, pythons and pwershells mixed up in some voodoo way) just blew my head off.

[gentledepp]

well... interestingly it worked out-of-the box on my windows machine :dancer:

[mattleibow]

I am closing this as the fix/commit seems to have removed all the kinks. It builds fine for me with m49/m52 as well as locally and on CI

[gentledepp]

hmmm... so what am I doing wrong here?

Also, where is your CI?
Is there any way to crab the nuget packages that are created in your CI? Please?

[gentledepp]

I seem to be just too dumb to get the build to work on mac.
I would greatly appreciate, if someone could supply me with a nuget build of the current master branch. Maybe as "alpha version"?
I really need this to continue developing my SVG editor/renderer based on Skia... :-|

[gentledepp]

Never mind - I got it to work! (I am such a n00b so thank you for hanging in with me)
