[Buildroot] [PATCHv2 1/1] xterm: x-includes and x-libraries must be set for cross-compiling

[kyak]

From: Mikhail Peselnik <bas@bmail.ru>

These flags need to be set so that the configure script would
correctly use libICE from cross-toolchain rather than from host.
Also, the xterm package is missing the freetype2 dependency, as
noted by Romain Naour.

This fix is similar to "package/efl/libevas: x-includes and x-libraries
must be set for cross-compiling" done by Romain Naour on libecore.

The From filed does not match your Signed-off-by; please fix your git

    git config --global user.name 'Mikhail Peselnik'

This should be a 'select' rather than a 'depends on'.

I guess this should instead be: -I$(STAGING_DIR)/usr/include

And this: -L$(STAGING_DIR)/usr/lib

You may also want to add:

    --with-freetype-config=$(STAGING_DIR)/usr/bin/freetype-config

This patch does two things: add x-includes, x-libraries and add freetype2
dependency.
It would be good to split these changes in two different patches.

In not sure about select. There is a --disable-freetype option, see below.

Maybe something like this (untested):

ifeq ($(BR2_PACKAGE_FREETYPE),y)
XTERM_CONF_OPTS += --with-freetype-config="$(STAGING_DIR)/usr/bin/freetype-config" \
                   --with-freetype-cflags="-I$(STAGING_DIR)/usr/include" \
                   --with-freetype-libs="-L$(STAGING_DIR)/usr/lib"
else
XTERM_CONF_OPTS += --disable-freetype
endif

But it you think that freetype must always be selected, this is ok.

Thoughts ?

Romain Naour

Are you sure?

In the patch itself, I see:

  From: Mikhail Peselnik <bas@bmail.ru>
  Signed-off-by: Mikhail Peselnik <bas@bmail.ru>

which does match. However, it indeed doesn't match the From of the mail
itself:

  From: kyak <bas@bmail.ru>

Which I'm not sure is related to the Git configuration. And while it's
a bit ugly, I think it doesn't cause any problem because Git will use
the From: from inside the patch itself in preference over the From: of
the e-mail.

[Buildroot] [PATCHv2 1/1] xterm: x-includes and x-libraries must be set for cross-compiling

Hello,

So it should be two patches.

Basically, if your patch does something that isn't summarized in the
commit title, then probably something wrong is going on.

So, one patch for x-includes/x-libraries, one patch for the missing
freetype2 dependency.

However, I believe Romain was maybe wrong: the freetype dependency
seems to be optional, according to configure.in. So it should probably
just be:

ifeq ($(BR2_PACKAGE_FREETYPE),y)
XTERM_DEPENDENCIES += freetype
XTERM_CONF_OPTS += --enable-freetype
else
XTERM_CONF_OPTS += --disable-freetype
endif

Romain, can you confirm?

Thomas

Ah, right. Then it would be:

    git conmfig --global sendemail.from 'Mikhail Peselnik <bas@bmail.ru>'

Indeed, forget what I said. I was just a bit surprised that the From
field in the mail headers did not match the SoB line; but since there's
a From field in the patch itself, all is good wrt. git keeping
authorship.

I don't know much the xterm package but indeed the freetype support seems
optional. However, it depends on libXft.

So I made this change:

# freetype support needs libXft, so enable it only when
# libxft package is selected.
# Note: freetype is automatically selected by libXft.
ifeq ($(BR2_PACKAGE_XLIB_LIBXFT),y)
XTERM_DEPENDENCIES += freetype xlib_libXft
XTERM_CONF_OPTS += --enable-freetype \
	--with-freetype-cflags="-I$(STAGING_DIR)/usr/include/freetype2" \
	--with-freetype-libs="-L$(STAGING_DIR)/usr/lib"
else
XTERM_CONF_OPTS += --disable-freetype
endif

It doesn't work when freetype-config is used directly with:
--with-freetype-config=$(STAGING_DIR)/usr/bin/freetype-config

Mikhail, can you resend an updated version with this change?

Romain

No, I think it's not the way it works. What xterm calls "freetype" is
*not* freetype, it's libXft, i.e X Freetype. If you look at the
definition of CF_X_FREETYPE, it searches for xft, and never for
freetype.

Don't add this comment.

Don't add the freetype dependency here.

I think these are wrong. Instead, do:

	--with-freetype-config=auto

It will use pkg-config to find libXft. Of course, make sure
host-pkgconf is in the dependencies.

> It doesn't work when freetype-config is used directly with:

Yes, because it's not looking for freetype, but Xft.

Thanks for the explanation, I was completely confused between (the real)
freetype and libXft...
Let me (or Mikhail) look again at the issue ;-)
