The Ubuntu packages of libstdc++-7-dev:amd64 and libstdc++-7-dev:armhf
do not correctly co-install due to a differing shared file in
/usr/include/c++/7/ext/random. This issue is not present in Debian
stable or unstable as far as I can tell, nor is it in Ubuntu 16.04.
The error is:
dpkg: error processing archive
/tmp/apt-dpkg-install-8t5R5l/13-libstdc++-7-dev_7.3.0-27ubuntu1~18.04_armhf.deb
(--unpack):
trying to overwrite shared '/usr/include/c++/7/ext/random', which is different
from other instances of package libstdc++-7-dev:armhf
dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)
Errors were encountered while processing:
/tmp/apt-dpkg-install-8t5R5l/13-libstdc++-7-dev_7.3.0-27ubuntu1~18.04_armhf.deb
To reproduce:
docker run -it ubuntu:bionic /bin/bash
apt update && apt install clang libstdc++-7-dev-armhf-cross
echo -e "#include <string>\nint main() { std::string a; }" > test.cpp
dpkg --add-architecture armhf
sed -i 's/deb /deb [arch=amd64] /' /etc/apt/sources.list && egrep "^deb "
/etc/apt/sources.list | sed 's/amd64/armhf/' | sed
's|http://.*.ubuntu.com/ubuntu/|http://ports.ubuntu.com/|' >>
/etc/apt/sources.list
apt update && apt install libstdc++-7-dev:armhf
# here is the bug

# manually removing "random" allows package to install
rm /usr/include/c++/7/ext/random
apt -f install
clang++ -target arm-linux-gnueabihf test.cpp
# WORKS
