ld: -r and -pie may not be used together

ld: -r and -pie may not be used together

./build-rr.sh hw fails in linking with error ld: -r and -pie may not be used together
Maybe a solution is replacing -Wl,-r only with -r, but I'm not sure yet because of other compiler errors afterwards…

What (Linux) distribution are you building on which is enabling -pie? The compiler specs in app-tools have never been tested in this situation and would need to be updated to disable -pie.

Debian stretch's gcc generally has -pie (or something in this area)
enabled by default.

I have the same problem. Any news?

The same problem on Ubuntu 16.10, works fine on 16.04

EDIT1:
It seams like they added -pie by default
https://wiki.ubuntu.com/SecurityTeam/PIE

EDIT2:
Compiling everything with -no-pie flags doesn't work either

@harnen Regarding the error in EDIT2, this looks like issue #86 & #82 , i.e. problems with g++ 6. Currently the workarounds for this error are to either disable C++ support in Rumprun (using CXX=false ./build-rr.sh) or to downgrade to GCC 5.

@gandro Thans a lot!
Combining CXX=false and -no-pie flags seems to work on my Ubuntu 16.10
CXX=false ./build-rr.sh hw -- -F ACLFLAGS=-no-pie

Would someone like to prepare a pull request that fixes this in build-rr.sh, by passing -no-pie ? I think that flag should be fine everywhere. Ian.

Unfortunately -no-pie is not supported by all gcc versions, so it should be added conditionally.

Still a problem on Ubuntu 17.04

On Debian Stretch when I use CXX=false ./build-rr.sh hw -- -F ACLFLAGS=-no-pie everything will successfully build, but when I try and compile anything with x86_64-rumprun-netbsd-gcc I get the error cc1: error: command line option '--no-pie' is valid for the driver but not for C. Running with --verbose it seems that -no-pie is being passed to /usr/lib/gcc/x86_64-linux-gnu/6/cc1 which doesn't accept that flag. Does anyone else experience the same behavior?
