Bug 158417 – REGRESSION(r201449) [GTK] ARMv7 build fails with libicudata.so.55: cannot open shared object file on gtkdoc-scangobj step

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Carlos Alberto Lopez Perez]

After r201449 <http://trac.webkit.org/r201449> The GTK+ ARM buildbot is failing to build with the following output:

[Carlos Alberto Lopez Perez]

I can reproduce the problem on a wandboard running Debian 8 Jessie.

The issue is related to this:

1) wandboard ~/WebKit $ file WebKitBuild/Release/Documentation/webkitdomgtk-4.0/webkitdomgtk-4.0-scan
WebKitBuild/Release/Documentation/webkitdomgtk-4.0/webkitdomgtk-4.0-scan: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=96abf72688893997831d15db58f8c814c4ce91e0, not stripped


2) wandboard ~/WebKit $ ldd WebKitBuild/Release/Documentation/webkitdomgtk-4.0/webkitdomgtk-4.0-scan | grep icu

	libicudata.so.55 => not found
	libicudata.so.55 => not found


When the ldd command is run inside the JHBuild environment (LD_LIBRARY_PATH env variable) the linker is not able to resolve the library dependencies.

My wild guess is that maybe webkitdomgtk-4.0-scan has been built outside of the JHBuild because it is linking against libicudata.so.52 instead of libicudata.so.55 ?

[Carlos Alberto Lopez Perez]

The libraries seem all there:

[Carlos Alberto Lopez Perez]

After some tests I was able to reduce the problem to this:

1) Save this C code example http://stuf.ro/reading-a-utf-8-file-in-c-with-icu as testicu.c
2) Compile it as follows:
$ gcc $(pkg-config --cflags --libs icu-io) testicu.c -o testicu


If you do this on the standard environment (outside of JHBuild) everything works as expected.

However, if you do that inside the internal JHBuild shell then everything goes wrong.

$ echo "Hello world!" > utf8_test.txt

Indeed, very same issue.

Applying the above Debian patch to the icu sources and rebuilding fixes the build and al liking problems.

wandboard ~/WebKit $ LD_LIBRARY_PATH=$(pwd)/WebKitBuild/DependenciesGTK/Root/lib ldd WebKitBuild/Release/bin/WebKitWebProcess |grep icu
	libicui18n.so.55 => /home/igalia/WebKit/WebKitBuild/DependenciesGTK/Root/lib/libicui18n.so.55 (0xb454d000)

	libicudata.so.55 => /home/igalia/WebKit/WebKitBuild/DependenciesGTK/Root/lib/libicudata.so.55 (0xb1298000)


I'm going to upload a patch ASAP.

Looks like we run about 10 sed scripts to do this not only here but also to a bunch of different Makefiles when building the Fedora package... so this solution is much simpler than what we have.
