Is it possible to compile libadblockplus on/for Raspberry pi?

Is it possible to compile libadblockplus on Raspberry pi?

I tried compiling on rpi and cross compile from ubuntu but both didnt worked.

[hemant]

I have got following error while building on ubuntu

In the listing above the linker cannot find the implementation of some functions from v8. So, I would recommend to check v8, may be it needs to be updated or merely some option in gyp file needs to be set to the correct value.
@hemant, Could you please provide details how you are doing it, so we can reproduce the exact state to identify the issue?

Hi,

Sorry for really late reply.
I am following checkout steps defined at
​https://adblockplus.org/forum/viewtopic.php?t=17093

after checkout source I just run
"make ARCH=arm7"
in "libadblockplus" folder.

I also tried compiling libadblockplus on my rpi 2 box but got same error.

[hemant]

Above error was due to missing build for arm related files of v8.
I got it build after added arm7 in third_party/v8/tools/gyp/v8.gyp file.

"Line:550 --> ['v8_target_arch=="arm" or v8_target_arch=="arm7"', {"

also I have to disable snapshot in third_party/v8/build/features.gypi file.

Line:44 'v8_use_snapshot%': 'false',

Congratulations with the compiling it!

Sounds like there is a trouble with the implementation of AdblockPlus::WebRequest. Could you check what implementation is used, may be you need to provide your component which is able to download data.
Check which GET is called in WebRequestThread::Run at WebRequestJsObject.cpp:61 (​https://hg.adblockplus.org/libadblockplus/file/283cfc113717/src/WebRequestJsObject.cpp#l61)

Thanks for pointers.

Following is the call stack for GET its calling dummy function which is by default setting error code.

AdblockPlus::DefaultWebRequest::GET (this=0xb6501cf8, url=..., requestHeaders=...) at ../src/DefaultWebRequestDummy.cpp:23
(gdb) where
#0  AdblockPlus::DefaultWebRequest::GET (this=0xb6501cf8, url=..., requestHeaders=...) at ../src/DefaultWebRequestDummy.cpp:23

(gdb)

From DefaultWebRequestDummy.cpp

 20 AdblockPlus::ServerResponse AdblockPlus::DefaultWebRequest::GET(
 21     const std::string& url, const HeaderList& requestHeaders) const
 22 {
 23   AdblockPlus::ServerResponse result;
 24   result.status = NS_ERROR_FAILURE;
 25   result.responseStatus = 0;
 26   return result;
 27 }

Is there any sample code for WebRequest which I can use to write GET function for linux?

Yes, even more, if you can use libcurl you can try to use libadblockplus\src\DefaultWebRequestCurl.cpp instead of dummy.

Thanks alot its not showing any error now and patterns.ini is having patterns :).

Thanks again for your help :).
