We are trying to cross compile stdcxx library. The problem we are facing
is that there is no way of telling stdcxx build system, that we don't
want to run configuration files created by configuration step by build
system directly on a host system (through a shell).
For instance, this command (taken from log):
invoked during configuration process runs natively the executable through
However we want to be able to run it on an emulator like this:
<path to our emulator> UNISTD_DECL
This command will run the UNISTD_DECL through an emulator.
The patch we are proposing, is to introduce a new Makefile variable, called
EXEC_RUNNER, which allows us to do it.
EXEC_RUNNER defaults to "/bin/sh -c". so it does not interfere with
the rest of build process (at least on Unix/MSys/Cygwin environment,
pure Win32 platform has completely separate build system).
Patch is against `trunk'.
