[Buildroot] [PATCH v2 2/2] package/chawan: new package

[Waldemar Brodkorb]

Chawan is a text-mode web browser and pager for Unix-like systems, with
a focus on implementing modern web standards while remaining
self-contained, easy to understand and extensible.

It includes functionality such as CSS, inline images inside the
terminal, and JavaScript through a small, independent browser engine.

I've applied to master, with some changes.

This was very very wrong, as it means you're changing this variable
for everyone in Buildroot. Variables are global.

"make check-package" actually warned about this:

WARNING: package/chawan/chawan.mk:23: possible typo, variable not properly prefixed: TARGET_CONFIGURE_OPTS -> *CHAWAN_XXXX* (https://nightly.buildroot.org/#_tips_and_tricks)

> +	PREFIX="/usr"

So I've changed this to:

+CHAWAN_MAKE_OPTS = \
+       $(TARGET_CONFIGURE_OPTS) \
+       FLAGS="--os=linux \
+       --cpu:$(CHAWAN_TARGET_ARCH) \
+       --gcc.exe:$(TARGET_CROSS)gcc \
+       --gcc.linkerexe:$(TARGET_CROSS)gcc" \
+       PREFIX="/usr"

and then used CHAWAN_MAKE_OPTS.

Continuation line should have had one more indentation level (minor
nit).

Applied with those changes. Thanks!

Could you have a look at the build failures caused by chawan and
propose some fixes?

chawan needs fenv.h, which is only available for a hard-float
uClibc-ng toolchain. Here arm soft-float is in use. How should I fix this? Any
suggestion?

If it's about the specific architecture:

depends on !BR2_or1k

So far we have ad-hoc dependencies in each package, so as a initial
fix I would suggest to do the same: exclude architecture/toolchain
combo that don't provide fenv.h.

On this initial fix is done, a better handling of fenv dependencies
would be nice. If you "git grep -i fenv" in Buildroot, you will see
that we have lots of packages that have custom dependencies to
workaround fenv availability issues.

Having in toolchain/Config.in some nice BR2_TOOLCHAIN_HAS_FENV_xyz
options (my understanding is that it cannot be just a single
BR2_TOOLCHAIN_HAS_FENV, because there are multiple exceptions, and
some architecture/toolchains support some which are sufficient for
some packages, but lack others which are needed by other packages).

As usual:

config BR2_PACKAGE_CHAWAN_ARCH_SUPPORTS
	bool
	default y
	depends on !BR2_or1k

config BR2_PACKAGE_CHAWAN
	bool "chawan"
	depends on BR2_PACKAGE_CHAWAN_ARCH_SUPPORTS
