Source: libalgorithm-svm-perl Version: 0.13-4 Tags: patch 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. Helmut
