Changes v1 -> v2:
        - fix comments following new policy
        - rename patches
        - remove useless hook points
        - add the URL to the home of MySQL
        - add commit-log description to the patches
        - install host tools to $(HOST_DIR)/usr/bin
        - fix only builds the required program

The patch is space-mangled: tabs were replaced by spaces.
So we can't apply it.

Please fix your mailer, or better yet, use 'git send-email' to send your
patches.

However, still a few comments, below...

As I said in my previous review, the patches should be named as:
    mysql_client-0000-ac_stack_direction-is-unset.patch
    mysql_client-0001-Fix-gen_lex_hash-execution.patch

Ie. they should be numbered.

I know the existing patches are not, so just provide a preliminary patch
that renames them, please.

You can't rename the option: it should match the name of the package.
The package infrastructure uses that to decide if a package should be
built or not.

But since the mysql_client package may now also be able to build the
server part, it could make sense to rename the package. But even then,
it should be done in a different patch, eg:
  - patch-1: rename the package and the existing patches
  - patch-3: add support for building the server

In patch-1, don;t forget to add the option in Config.in.legacy.

What about just:
    "MySQL needs a toolchain w/ C++, threads"

What if neither the client nor the server is selected? Does that make
sense? If not, then always build the client (as we currently do), and
make the server an option (as you did in your previous patch).

"exit 0" is not needed.

This is more descriptive, as it states the reason, and explains the fix:

    Makefile: fix cross-compiling the server

    MySQL Makefile believes it can run code it just compiled, to
    generate a header. This does not work for cross-compilation.

    Instead, use a pre-installed host-version of the required tool.

I would move all those new options in the

This is getting really good! :-)

I would suggest:

config BR2_PACKAGE_MYSQL
	bool "mysql"
	select BR2_PACKAGE_MYSQL_CLIENT if !BR2_PACKAGE_MYSQL_SERVER

if BR2_PACKAGE_MYSQL

config BR2_PACKAGE_MYSQL_CLIENT
	bool "client"

config BR2_PACKAGE_MYSQL_SERVER
	bool "server"

endif

This way, we guarantee that at least either the client or the server
are enabled.

Hi Thomas, all

This is the new Config.in file:

config BR2_PACKAGE_MYSQL
        bool "mysql"
        depends on BR2_INSTALL_LIBSTDCPP
        depends on BR2_USE_MMU # fork()
        depends on BR2_TOOLCHAIN_HAS_THREADS
        select BR2_PACKAGE_MYSQL_CLIENT  if !BR2_PACKAGE_MYSQL_SERVER
        select BR2_PACKAGE_NCURSES
        select BR2_PACKAGE_READLINE
        help
          The MySQL Open Source Database System

          http://www.mysql.com/

comment "MySQL needs a toolchain w/ C++, threads"
        depends on BR2_USE_MMU
        depends on !BR2_INSTALL_LIBSTDCPP || !BR2_TOOLCHAIN_HAS_THREADS


if BR2_PACKAGE_MYSQL_CLIENT

config BR2_PACKAGE_MYSQL_CLIENT
       bool "client"
       help
          Install the MySQL client on the target.

config BR2_PACKAGE_MYSQL_SERVER
        bool "server"
        help
          Install the MySQL server on the target.

endif


But I'm getting this issue:

$ make menuconfig
package/mysql/Config.in:1:error: recursive dependency detected!
package/mysql/Config.in:1:      symbol BR2_PACKAGE_MYSQL is selected
by BR2_PACKAGE_MYSQL_CLIENT
package/mysql/Config.in:21:     symbol BR2_PACKAGE_MYSQL_CLIENT is
selected by BR2_PACKAGE_MYSQL

Best,
Marcelo
