Source: gdb
Version: 17.1-1
Tags: patch
User: [email protected]
Usertags: cross-satisfiability ftcbfs
gdb fails to cross build from source for three distinct reasons.
1. The build-dependency on gobjc is not satisfiable. It is a toolchain
dependendency and needs to specify what the compiler is being used
for. Most commonly, one targeting the host architecture is needed.
This is achieved by using gobjc-for-host.
2. The build-dependency on python3-dev is not installable. It implies a
host architecture Python interpreter. Python extensions should
depend on python3-dev:native plus libpython3-dev instead.
3. In bfd/doc, chew.c uses host compiler flags with the build compiler.
This fails badly when compiling for amd64 or arm64.
I'm attaching a patch that addresses all mentioned issues. Please
consider applying it. The part fixing chew.c should be suitable for
upstream inclusion.
