User: [email protected]
Usertags: ftcbfs
libalgorithm-svm-perl fails to cross build from source, because the
upstream build system wants to use a C++ compiler with Perl's
ExtUtils:MakeMaker and thus overrides the chosen C compiler. In doing
so, it forces a build architecture compiler where a host architecture on
would be needed. Since Perl does not usually use C++, the host
architecture C++ compiler is not something we can query from Perl. I
propose honouring the CXX environment variable and supplying it from
debian/rules instead. Once doing so, libalgorithm-svm-perl cross builds
successfully. I'm attaching a patch for your convenience.
