--- Comment #2 from Bradley Gamble <bradley.gamble at ncipher.com> ---
The build is completed in a single container without any sort of file
migration. My build commands are:
wget https://buildroot.org/downloads/buildroot-2019.05.1.tar.gz
tar -xvf ./buildroot-2019.05.1.tar.gz
cp ./baseimage/defconfig ./buildroot-2019.05.1/configs/custom_defconfig
make -C buildroot-2019.05.1 custom_defconfig
make -C buildroot-2019.05.1
This completes successfully, for example, on my host machine with newer
libraries.
In the container I am able to build and C++ applications without issue - We
compile many C++ binaries from source and this example of Patchelf is the only
failure we've encountered. I have demonstrated this by building a hello world
example:
$ cat helloworld.cpp
#include <iostream>
using namespace std;
int main()
{
cout << "Hello, World!";
return 0;
}
$ g++ helloworld.cpp -ohelloworld
$ ./helloworld
Hello, World!
I have uploaded the files here: https://gofile.io/?c=INwQ9u (Apologies for the
third-party host, the binaries are too big to upload even when compressed.)
This tarball contains the Patchelf binary and log from Buildroot, as well as
one I have manually compiled in the container. The Buildroot binary fails to
execute from within the container, whereas the manually built one executes
without issue.
