gdb-8.2.1 build failed on macos 10.11.6

[Jiri Gaisler]

I don't know if it is of any help, but I managed to build gdb-8.2.1 on
MacOSX 10.10 using gcc-9. The trick was to install gcc with 'brew
install gcc', and then configure and compile with CC=gcc-9 and CXX=g++-9
. I'm doing this in a KVM virtual machine, but I don't think it matters.
The resulting gdb binary worked fine. I am now trying to build the whole
tool-chain with RSB ...


brew install gcc

export CC=gcc-9

export CXX=g++-9

../gdb-8.2.1/configure --target=sparc-rtems

make -j2

Jiri.
