Older objcopy mangles bootloader built with musl #205

Open JonathonReinhart opened 3 years ago

JonathonReinhart commented 3 years ago

Long stories (#198, #203) very short: objcopy on CentOS 7 mangles the program headers of a bootloader built with musl-gcc on Debian bullseye.

Built on: Debian bulseye, gcc 10.2.1, musl-tools 1.2.2-1

Distro objcopy Status
CentOS 7 2.27-44.base.el7 :x: Fail
Debian 9 2.28 :x: Fail
Ubuntu 18.04 2.30 :x: Fail
Debian 10 2.31.1 :x: Fail
Debian 11 2.35.2 :heavy_check_mark: OK

Workaround

Don't install the published wheels:

pip install --no-binary=staticx staticx

Just for your information. The install of staticx from source worked to solve segfaulting binaries generated within docker container based on official python:3 image. To get the installation running I had to install scons within the container first.
