Package: lintian
Version: 2.18.0
Severity: normal

Running lintian on the libc6-dev package leads to the following error:

| Command ar t usr/lib/x86_64-linux-gnu/libm.a exited with status 1: ar: usr/lib/x86_64-linux-gnu/libm.a: file format not recognized
| warning: collect info ar-info about package libc6-dev failed (512)
| warning: skipping check of binary package libc6-dev

This libm.a file is actually not an ar archive, but a linker script:

| /* GNU ld script
| */
| OUTPUT_FORMAT(elf64-x86-64)
| GROUP ( /usr/lib/x86_64-linux-gnu/libm-2.28.a /usr/lib/x86_64-linux-gnu/libmvec.a )

lintian should probably check the type of the file before trying to
unpack it, as already done for .so files.

A comment was left in the code to alert later editors to that
behavior. The commit is located at:

    https://salsa.debian.org/lintian/lintian/commit/9bea0ddfd775ae8129ee2f63708e0f4146584957

No other action was taken. Thank you for reporting the issue. Closing the bug.

Kind regards,
Felix Lechner
