php55-pecl-krb5 or php55-php-pecl-krb5 ?

For my curiosity, why do you need the .src.rpm when the binary packages are available ?

And, I use the same spec (and .src.rpm) for base ans SCL packages (so php-pecl-krb5)

> In future this modifications will be applyed in upstream php-pecl-krb5.
Yeah (it was my next question)

It build php-pecl-krb5 if standard env.
it will never build php55-pecl-krb5
it build php55-php-pecl-krb5 in SCL environment (when php55-build is installed in the buildroot)

to build this package, you need php55-php-devel (which is in the BuildRequires)

So I don't even understand how this can happen...

Once again, I don't know what you change in the original spec, but it contains

BuildRequires:  krb5-devel >= 1.8
BuildRequires:  pkgconfig(com_err)
BuildRequires:  %{?scl_prefix}php-devel > 5.2
BuildRequires:  %{?scl_prefix}php-pear

So with php55-php-devel + php55-php-pear, you should have everything needed

I think I understand your issue.

/opt/rh is default SCL prefix

I use, /opt/remi to make explicitly this a package from my repo, and to not conflict with RHSCL collections.

vendor is not defined in "macros.php55-config" by design, so people rebuilding my php spec (main package) will not use "remi" in the prefix.
but of course this breaks the build of php extension.

So you have to define, in your build environment.
  %scl_vendor = remi
  %_scl_prefix =/opt/remi

P.S. see https://github.com/remicollet/remirepo/ … xscl55.cfg

How are you running the build ? (rpmbuild, mock, koji ?)

Terrible bad idea....

It seems you have both php-devel and php55-php-devel...

So __ztsphp is defined during the build.
You have to remove php-devel.

Notice: "mock" is the way to go, especially for SCL package.
Having php55-build installed in your env is really a bad idea.
