Summary0000093: file incorrectly recognizes -static-pie binaries
Descriptionfile recognizes binaries build with gcc using -static-pie as dynamically linked binaries.
Steps To Reproduce1. Create a simple hello word C program
2. Compile it using gcc -fPIE -static-pie -o test test.c
3. Run file on the resulting binary

Output:

test: ELF 64-bit LSB pie executable, x86-64, version 1 (GNU/Linux), dynamically linked, BuildID[sha1]=4594afb38f3f60aaad10d08ab519fcaeae55ee70, for GNU/Linux 3.2.0, not stripped

It should actually be reported as statically linked, check with ldd:

$ ldd test
    statically linked

TagsNo tags attached.

I can't reproduce this

"-static -pie" and "-static-pie" are not the same thing. You need a relatively recent gcc for the latter https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=252034

I used gcc (GCC) 9.1.0.

I don't have an environment like that available. Can you just attach a binary?

The previous comment contained a binary.
