php 7 support ? about mlt

[ddennedy]

It depends on SWIG, which generates the code. See swig/swig#571

Fedora 25 had update swig to 3.0.11 which claims that have php7 support , but mlt still not compile with php7 I added

sed -i 's|-php5|-php7|g' src/swig/php/build

but finish with :

[ddennedy]

Ignore the warnings and just look at the error. Obviously, it not longer writes a mlt_wrap.cpp file. What file does this version of SWIG write? Look yourself; it should be obvious. Then, try changing src/swig/php/build to compile the correct file. You will also need to change the link line.

Good tip, this make it work :

%if 0%{fedora} >= 25
sed -i 's|-php5|-php7|g' src/swig/php/build
sed -i 's|mlt_wrap.cpp|mlt_wrap.cxx|g' src/swig/php/build
%endif

Thanks
