Tim Armstrong commented on IMPALA-5078:
---------------------------------------
The build system is a bit of a beast unfortunately.
I forgot to mention that you need to source the config script before running
make. That sets a bunch of environment variables that are needed to build
things. I suspect that might be the problem since it looks like the first error
is happening because USE_SYSTEM_GCC is undefined. Otherwise maybe the cmake
files need to be regenerated:
I.e. something like
{noformat}
. bin/impala-config.sh
./buildall.sh -noclean -cmake_only # If you changed CMake files you need to
regenerate them like this.
make expr-test
make fe # If you changed any of the frontend or java stuff, you might also
need to rebuild that.
{noformat}
> Break up expr-test.cc

> {{expr-test.cc}} clocks in at 7129 lines, which is about enough for my emacs
> to start slowing down a bit. Let's see if we can refactor it enough to have a
> couple of test files. Maybe moving all the string instructions into a
> separate {{expr-string-test.cc}}, and having a common header will be enough
> to make it a bit more manageable.
