WebKitGTK 2.32.1 includes fixes for building with the Musl libc, which also makes it possible to use uClibc as well, therefore arrange dependencies to allow selecting the package any of the C libraries is in use. This is done by making the dependencies be more granular, basically following what the wpewebkit package does. In order to make make it build against uClibc a small patch that has been submitted to the upstream's Bugzilla is needed.

Subject: [PATCH] Support building against uClibc
|
|
https://bugs.webkit.org/show_bug.cgi?id=226244
|
|
|
|
Reviewed by Michael Catanzaro.
|
|
|
|
Source/JavaScriptCore:
|
|
|
|
* assembler/MacroAssemblerARM64.cpp:
|
|
(getauxval): Provide a fallback implementation of getauxval() for
|
|
systems which do not provide <sys/auxv.h>, like those using uClibc
|
|
as their C library.
|
|
|
|
Source/WTF:
|
|
|
|
* wtf/PlatformRegisters.h: Use the <sys/ucontext.h> header instead of
|
|
<ucontext.h>, which is enough to gain access to the type definitions
|
|
for CPU registers and is available on every libc. On the other hand,
|
|
uClibc does not have <ucontext.h>, so this fixes the build in that
|
|
case.
