Re: Cross compilation issue for Android

NDK23c does not provide any libgcc libraries. This is reasonable, since it also does not provide a gcc: it uses clang instead. I’ve never tried to build Valgrind for Android, but hopefully someone else can tell you how to do it with a modern NDK.

Subject: [Valgrind-users] Cross compilation issue for Android

  Hello Valgrind Users,

I am trying to cross compile the valgrind for Android using NDK. But I am seeing the compilation error. Has anyone faced a similar issue?
