yocto - bitbake: adding php-intl support to php recipe

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

Something is wrong with the PHP 7.2.1 recipe. If you you are on "thud" branch for your layers then you might want to either switch to "warrior" branch and re-run the bitbake php -v command or copy the recipe for php 7.3.x + files to your php recipe directory from here https://github.com/openembedded/meta-openembedded/tree/master/meta-oe/recipes-devtools/php.

Also, you could just use the PACKAGECONFIG option. Your mileage will vary to the third party libs you want for your php build. I got php intl working on both thud and warrior branches using the following updated recipe for PHP 7.3.4:

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

EXTRA_OECONF =+ " --enable-mbstring --with-openssl=${STAGING_DIR_TARGET}${exec_prefix} --enable-bcmath --enable-sockets --enable-intl 
                      , 
                      , icu-native icu"
PACKAGECONFIG ??= "intl sqlite3"
PACKAGECONFIG[sqlite3] = "--with-openssl=${STAGING_DIR_TARGET}${exec_prefix} 
              --with-sqlite3=${STAGING_LIBDIR}/.. 
                          --with-pdo-sqlite=${STAGING_LIBDIR}/.. 
                          , 
                          ,sqlite3"

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