bitbake：为php配方添加php-intl支持

Question

I need to build a php package supporting the intl extension with bitbake (http://php.net/manual/en/intl.installation.php).

So I created a bbappend:

bernardo@bernardo-UX51VZA:~/dev/yocto/meta-steempi$ cat recipes-devtools/php/php_7.%.bbappend 

DEPENDS += " icu apache2"
RDEPENDS_${PN} += " icu apache2"

PACKAGECONFIG_append_pn-php = " apache2 icu icu-dev"
EXTRA_OECONF += " --with-openssl=${STAGING_DIR_TARGET}${exec_prefix} \
                  --with-config-file-path=${sysconfdir}/php/apache2-php${PHP_MAJOR_VERSION} \
                  --with-icu-dir=${BASE_WORKDIR}/${MULTIMACH_TARGET_SYS}/icu/60.2-r0/image/usr \
                  --enable-intl \
"

To enable the intl compilation, I added the --enable-intl and --with-icu-dir to EXTRA_OECONF. However, the configure task presents the following error, even though the path to icu-config was added to --with-icu-dir.

...

I suspect the configure is trying to find icu's headers, because the icu-config script (generated by icu recipe) is set with the right path.

When I try to add icu-dev to the DEPENDS variable in my bbappend, I get

ERROR: Nothing PROVIDES 'icu-dev' (but /home/leprechaun/dev/yocto/meta-openembedded/meta-oe/recipes-devtools/php/php_7.2.4.bb DEPENDS on or otherwise requires it). Close matches:
  udev
  icu RPROVIDES icu-dev
ERROR: Required build target 'php' has no buildable providers.
Missing or unbuildable dependency chain was: ['php', 'icu-dev']

When I try to add icu-dev to the RDEPENDS variable in the bbappend, I get the following error:

ERROR: Nothing RPROVIDES 'icu-dev-native' (but virtual:native:/home/leprechaun/dev/yocto/meta-openembedded/meta-oe/recipes-devtools/php/php_7.2.4.bb RDEPENDS on or otherwise requires it)

Missing or unbuildable dependency chain was: ['icu-dev-native']
ERROR: Required build target 'php' has no buildable providers.
Missing or unbuildable dependency chain was: ['php', 'php-native', 'icu-dev-native']

Any ideas on how to get out of this hole?

Thanks!

I had the same issue and took me a while but I got the php build working. This is my .bbappend file:

EXTRA_OECONF_append_class-target = " --with-curl=${STAGING_LIBDIR}/.."
DEPENDS_append_class-target = " icu curl"

EXTRA_OECONF =+ " --enable-mbstring --with-openssl --enable-bcmath --enable-sockets --enable-intl \
                                          --with-icu-dir=${BASE_WORKDIR}/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/icu/62.1-r0/recipe-sysroot-native/usr \
                      , \
                      , icu-native icu"
PACKAGECONFIG ??= "sqlite3"
PACKAGECONFIG[sqlite3] = "--with-sqlite3=${STAGING_LIBDIR}/.. \
                          --with-pdo-sqlite=${STAGING_LIBDIR}/.. \
                          , \
                          ,sqlite3"

LIBS_pn-php =" -lpthread "
export LIBS
THREADS_pn-php = "pthread"
export THREADS
