pkg-infra: add <pkg>_CONFIG_FIXUP to fix *-config files
This patch will add <pkg>_CONFIG_FIXUP variable to buildroot infra. It's purpose is to inform buildroot that the package in question contains some $(STAGING_DIR)/usr/bin/*-config files and that we want to automatically fix prefixes of such files. It is often the case that many packages call these files during their configuration step to determine 3rd party library package locations and any flags needed to link against them. For example: Some package might try to check the existense and linking flags of NSPR package by calling $(STAGING_DIR)/usr/bin/nspr-config --prefix. Without this fix. NSPR would return /usr/ as it's prefix which is wrong when cross-compiling. Correct would be $(STAGING_DIR)/usr. All packages that have <pkg>_INSTALL_STAGING = YES defined and also install some config file(s) into $(STAGING_DIR)/usr/bin must hereafter also define <pkg>_CONFIG_FIXUP with the correspondig filename(s). For example: DIVINE_CONFIG_FIXUP = divine-config or for multiple files: IMAGEMAGICK_CONFIG_FIXUP = Magick-config Wand-config Signed-off-by: Stefan Fröberg <stefan.froberg@petroprogram.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

On line 12, we specify that there is some fixing to be done to some
|
||||
of the 'libfoo-config' files that were installed during
|
||||
+LIBFOO_INSTALL_STAGING_CMDS+ phase.
|
||||
These *-config files are executable shell script files that are
|
||||
located in '$(STAGING_DIR)/usr/bin' directory and are executed
|
||||
by other 3rd party packages to find out the location and the linking
|
||||
flags of this particular package.
|
||||
|
||||
The problem is that all these *-config files by default give wrong,
|
||||
host system linking flags that are unsuitable for cross-compiling.
|
||||
|
||||
For example: '-I/usr/include' instead of '-I$(STAGING_DIR)/usr/include'
|
||||
or: '-L/usr/lib' instead of '-L$(STAGING_DIR)/usr/lib'
|
||||
|

So some sed magic is done to these scripts to make them give correct
|

flags.
|

The argument to be given to +LIBFOO_CONFIG_FIXUP+ is the file name(s)
|
||||
of the shell script(s) needing fixing. All these names are relative to
|
||||
'$(STAGING_DIR)/usr/bin' and if needed multiple names can be given.
|
||||
|
||||
Example 1:
|
||||
|
||||
Package divine installs shell script '$(STAGING_DIR)/usr/bin/divine-config'.
|
||||
|
||||
So it's fixup would be:
|
||||
|
||||
DIVINE_CONFIG = divine-config
|
||||
|
||||
Example 2:
|
||||
|
||||
Package imagemagick installs the following scripts:
|
||||
'$(STAGING_DIR)/usr/bin/{Magick,Magick++,MagickCore,MagickWand,Wand}-config'
|
||||
|
||||
So it's fixup would be:
|
||||
|
||||
IMAGEMAGICK_CONFIG_FIXUP = Magick-config Magick++-config \
|
||||
MagickCore-config MagickWand-config Wand-config
