Doesn't build PIE version correctly?

[bigwave]

Hi,

First of all, a really useful docker container as all I needed was a PIE ssh client and I've never compiled NDK stuff before.

However the PIE output (at least for the ARM ssh client) wasn't actually a PIE executable.

It seemed that the final linking(?) command didn't have the PIE flags, so I brute forced a solution by adding -pie -fPIE to the end of the COMPILER=${TOOLCHAIN}/bin/arm-linux-androideabi-gcc line

Which worked, but I'm pretty sure this isn't the correct way to fix this.

Cheers,
Ian

I'm having this same issue. Did you ever find a more proper solution?

[bigwave]

Afraid not, once I had a PIE enabled executable I didn't need to look into this any more.

That's fine! Thanks anyways!

The answer is that the -pie flag have to be set on LDFLAGS for executables.
