Hi,

I am following the instruction of how to build skia, but i am getting this error

Which version of jpeglib do you have installed?

I have just upgrade to jpeg 9b and I check the jpeglib.h i for JCS prefix and it show

JCS_UNKNOWN, /* error/unspecified */

JCS_GRAYSCALE, /* monochrome */

JCS_RGB, /* red/green/blue, standard RGB (sRGB) */

JCS_YCbCr, /* Y/Cb/Cr (also known as YUV), standard YCC */

JCS_CMYK, /* C/M/Y/K */

JCS_YCCK, /* Y/Cb/Cr/K */

JCS_BG_RGB, /* big gamut red/green/blue, bg-sRGB */

JCS_BG_YCC /* big gamut Y/Cb/Cr, bg-sYCC */

I've fixed it by setting

is_official_build=false

Skia requires libjpeg-turbo, not libjpeg. What you're seeing missing are the APIs that Skia uses from libjpeg-turbo that were not originally present in libjpeg.

Here's a recent thread with a little more about this: https://groups.google.com/forum/#!topic/skia-discuss/8QCDED4S_Zo

HI Mike,

It is working with official build now after install libjpeg-turbo.

Thanks,

Running into a similar issue when compiling OsmAnd-core-legacy which depends on skia. (Xcode 9.2 on Mac OS Sierra 10.12 make 3.81)

I have installed libjpeg-turbo with brew but it does not help.

How do I force `make` to use libjpeg-turbo instead of libjpeg ?
