Spidermonkey is Mozilla's JavaScript engine written in C and C++. It is used in
various Mozilla products, including Firefox, and is available under the MPL2.
There are 10 patches currently required to properly cross-compile spidermonkey:
1) allow-newer-autoconf-versions
- Spidermonkey is hardcoded to use Autoconf 2.13, which is from 1999!
The reasoning behind using 2.13 is because newer versions of Autoconf do not
work correctly with the custom m4 macros in the source code.
However: Because we are building just the Spidermonkey engine instead of the
entire Firefox package, newer versions of Autoconf work without issue.
See: See: https://bugzilla.mozilla.org/show_bug.cgi?id=104642
for further explanation.
2) allow-building-in-tree
- By default, spidermonkey must be configured and built out-of-tree, otherwise
the following error occurs:
FATAL ERROR PROCESSING MOZBUILD FILE
==============================
The error occurred while processing the following file or one of the files
it includes:
js/src/shell/moz.build
The error occurred when validating the result of the execution. The reported
error is:
The path specified in LOCAL_INCLUDES is not allowed:
.. (resolved to js/src)
Remove this check, as spidermonkey builds without issue in-tree.
3) allow-unknown-configuration-options
- By default, if an unknown parameter is passed to configure, an error is
raised. Replace the raise with a pass and continue.
Fixes: https://bugzilla.mozilla.org/show_bug.cgi?id=1379540
4) fix-building-with-musl
- The MIPS specific header <sgidefs.h> is not provided by musl.
The Linux kernel headers <asm/sgidefs.h> provide the same definitions.
5) add-riscv-support
- Submitted upstream:
See: https://bugzilla.mozilla.org/show_bug.cgi?id=1318905
6) copy-headers-on-install-instead-of-symlinking
- When installing, instead of linking the headers to the source directory,
copy them.
7) ensure-proper-running-on-64-bit-and-32-bit-be-platforms
- Taken from the Fedora RPM
Applied upstream.
Fixes: https://bugzilla.mozilla.org/show_bug.cgi?id=1488552
8) 0008-save-and-restore-non-volatile-x28-on-ARM64-for-generated-unboxed-obje
- Taken from the Fedora RPM:
Applied upstream.
Fixes: https://bugzilla.mozilla.org/show_bug.cgi?id=1375074
9) save-x28-before-clobbering-it-in-the-regex-compiler
- Taken from the Fedora RPM:
Applied upstream.
Fixes: https://bugzilla.mozilla.org/show_bug.cgi?id=1445907
10) always-use-the-equivalent-year-to-determine-the-time-zone
- Taken from the Fedora RPM:
Applied upstream.
Fixes: https://bugzilla.mozilla.org/show_bug.cgi?id=1415202
Typically, The Firefox source tarball is used to build spidermonkey; however,
this has two disadvantages:
- It's large. The Firefox source tarball is over 250M.
- It requires Autoconf 2.13
Instead, use a tarball with only the Spidermonkey source code in it with a
pre-setup configure file. This tarball reduces the size to 31M and prevents the
Autoconf 2.13 requirement.
