unknown target 'cefclient' error

[magreenblatt]

Just confirming, looks like I didnt need the chrome build at all. I made the binary distribution without it, copied to target and built the app with no problem. The only thing is libcef.so is huge (I guess partly because of debug build)! 1.3 GB. This ends up being a problem (the app on the target gets stuck trying to load the huge so file). Is there an option to make a release build?

Build out/Release instead of out/Debug

ninja -C out/Release

Also you should adjust buildtype to official in gyp defines.

Thanks guys, I had to rebuild from scratch (this time official with GYP_DEFINES=buildtype=Official ) because I think build process got garbled up. Anyway, after re-downloading the sources a lot of older problems that I found last time disappeared, not sure what happened there but I met with a new error (theortetically a warning turned into compiler error because of gcc flags):

../../cef/libcef/browser/native/browser_platform_delegate_native_linux.cc:235:3: error: ignoring return value of function declared with 'warn_unused_result' attribute [-Werror,-Wunused-result]
system(openCommand.c_str());

I simply used a dummy int :
int dummy = system ( ...)
followed by a printf statement to fool the compiler into thinking I really need to use the variable. I did it this way as a hack, I guess real solution would be to change the function itself to return int and since its a virtual function , it has to be changed in all other places. So anyways, now with the similar compiler flags in place, I am getting a lot of linker "hidden symbol" warnings as errors for libharfbuzz-ng.a,

Aparently these symbols are declared as hidden inside libharfbuzz-ng.a, question is, is it built as part of the process? And how can I change the compiler flags so these are not treated as error ?

objdump -t ./out/Release/obj/third_party/harfbuzz-ng/libharfbuzz-ng.a | grep hidden | grep hb_font_destroy

Just saw this in harfbuzz.gyp, seems like a double edged sword. What can I do, eliminate the flag?

# When without -fvisibility=hidden for pango to use the harfbuzz
