Bug 68553 – [GTK][WK2] Error loading libMiniBrowserWebBundle.so

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit2

[Ravi Phaneendra Kasibhatla]

We encounter following message on MiniBrowser launch:
Error loading the injected bundle (Libraries/.libs/libMiniBrowserWebBundle.so): Libraries/.libs/libMiniBrowserWebBundle.so: cannot open shared object file: No such file or directory

Path of the library file to be corrected.

Remove this unrelated change from https://bugs.webkit.org/show_bug.cgi?id=68235 patch and adding it separately.

I'm going to add a helper function soon that discovers the binary location. Could this patch be changed to simply find the shared object relative to the binary location after that patch lands?

It's totally unecessary to cast to gpointer here.

Actually I was getting a compiler warning for passing const gchar to g_free though it expects a gpointer. So I casted it.

This should not be a const pointer, since g_build_filename allocaetes heap memory to hold the new string.

LIBEXECDIR is where executables for the library are installed. In this case, injected bundle is a library, not an executable. MiniBrowser is not installed, and the injected bundle library either.

As Martin says in comment 2 he has another plan for this bug as well. Maybe discuss a bit more about the approach to take to fix this bug? r- because of wrong use of libexecdir.

> Tools/MiniBrowser/gtk/GNUmakefile.am:8
> +	-DLIBEXECDIR=\""$(libexecdir)"\" \

This should point to the directory in $(top_builddir) storing the libMiniBrowserWebBundle.so. As Carlos points out it's not installed, so not available outside the build directory.

[Carlos Garcia Campos]

MiniBrowser doesn't use injected bundle anymore, so this problem is now fixed.
