Re: [PATCH 01/14] S390: Get rid of make warning: overriding recipe for target gconv-modules.


Ping. Is the new handling of gconv-modules in iconvdata/Makefile okay to commit?

On 02/23/2016 10:21 AM, Stefan Liebler wrote:
This patch introduces a way to provide an architecture dependent gconv-modules
file. Before this patch, the gconv-modules file was normally installed from
src-dir/iconvdata/gconv-modules. The S390 Makefile had overridden the
installation recipe (with a make warning) in order to install the
gconv-module-s390 file from build-dir.
The iconvdata/Makefile provides another recipe, which copies the gconv-modules
file from src to build dir, which are used by the testcases.
Thus the testcases does not use the currently build s390-modules.

This patch uses build-dir/iconvdata/gconv-modules for installation.
If makefile variable GCONV_MODULES is not defined, then gconv-modules file
is copied form source to build directory.
If an architecture wants to create his own gconv-modules file, then the variable
GCONV_MODULE is set to the name of the architecture-dependent gconv-modules file
in build-directory, which has to be created by a recipe in sysdeps/.../Makefile.
Then the  iconvdata/Makefile copies this file to build-dir/iconvdata/gconv-modules, which will be used for installation and test.

This way, the s390-Makefile does not need to override the recipe for gconv-modules and no warning is emitted anymore.

ChangeLog:

     * iconvdata/Makefile (GCONV_MODULES): New variable, which can
     be set by sysdeps Makefile.
     ($(inst_gconvdir)/gconv-modules):
     Install file from $(objpfx)gconv-modules.
     ($(objpfx)gconv-modules): Copy File from src-dir or from
     build-dir with file-name specified by GCONV_MODULES.
     * sysdeps/s390/s390-64/Makefile ($(inst_gconvdir)/gconv-modules):
     Deleted.
     (GCONV_MODULES): New variable.
