Build failure with riscv64 toolchain

[zetalog]

I tried sysbench with the following build steps:

./autogen.sh
./configure --host=riscv64-linux-gnu --without-mysql
make

And failed with:

make[1]: Entering directory '/home/zetalog/workspace/kuhan/sysbench/third_party/concurrency_kit'
rm -rf tmp
mkdir tmp
tar -C . -cf - ck | tar -xf - -C tmp/
chmod -R u+w tmp

It seems the concurrency_ck configure was trying to execute a target binary on host:

$CC -o .1 .1.c
COMPILER=`./.1 2> /dev/null`
r=$?
rm -f .1.c .1

What should I do to fix the issue? Thanks in advance.

I also created an issue to ck here if this issue is not meant to be fixed by sysbench: https://github.com/concurrencykit/ck/issues/193

ck riscv support is pushed here: https://github.com/concurrencykit/ck/pull/194

Do you cross compile a riscv binary on a X86 host machine? I found it will compile with gcc on x86 even if I select --host and --target variable.: ./configure --with-sysroot=/home/caelus/share/sysbench/rfs_ramfs --target=riscv32-linux-gnu --without-mysql --prefix=/mnt/sysbench --host=riscv32-linux-gnu

If I set CC to the cross tool chain, it wille stopped with error in

$CC -o .1 .1.c
COMPILER=`./.1 2> /dev/null`
r=$?
rm -f .1.c .1

Since it tried to run a riscv binary on a X86 machine.
