Bug 909746 – dev-libs/openssl-3.0.9-r1: crossdev: mipsel-unknown-linux-gnu-gcc: error: unrecognized command-line option ‘-m64’

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description Aaron D Borden 2023-07-06 01:59:46 UTC]

openssl fails to cross-compile using mipsel-unknown-linux-gnu-gcc via crossdev with error:

mipsel-unknown-linux-gnu-gcc: error: unrecognized command-line option ‘-m64’

Reproducible: Always

Steps to Reproduce:
1. crossdev --gcc 10.4.1 --libc 2.36 --binutils 2.40-r5 -t mipsel-unknown-linux-gnu
2.  mipsel-unknown-linux-gnu-emerge -v1 openssl
Actual Results:  
openssl configuration detects target linux-x86_64 and fails to compile

> Configuring OpenSSL version 3.0.9 for target linux-x86_64

Expected Results:  
openssl configuration detects linux-mips and compiles successfully.

I believe this is a regression. I have a MIPS system running openssl-1.1.1l compiled using the same method, so this was working at some point.

We seem to be lacking settings for mipsel in our openssl config files.

Hm, no, we do have:

$ grep -rsin mips
gentoo.config-1.0.2:102:                mips*el*)     machine="generic32 -DL_ENDIAN";;
gentoo.config-1.0.2:103:                mips*)        machine="generic32 -DB_ENDIAN";;
gentoo.config-1.0.4:104:                mips*el*:o32) machine="mips32 -DL_ENDIAN";;
gentoo.config-1.0.4:105:                mips*:o32)    machine="mips32 -DB_ENDIAN";;
gentoo.config-1.0.4:106:                mips*el*:n32) machine="mips64 -DL_ENDIAN";;
gentoo.config-1.0.4:107:                mips*:n32)    machine="mips64 -DB_ENDIAN";;
gentoo.config-1.0.4:108:                mips*el*:n64) machine="mips64 -DL_ENDIAN" system=linux64;;
gentoo.config-1.0.4:109:                mips*:n64)    machine="mips64 -DB_ENDIAN" system=linux64;;

but it's not matching them.

Hey Sam, thanks for pointing out the gentoo.config script. I'm using profile `default/linux/mips/23.0/mipsel`, without a specific ABI. Afaik, this is valid, although I'm no expert. I believe this profile does not set an ABI and then gentoo.config fails to match the mips rules.

If I set the profile `default/linux/mips/17.0/mipsel/o32` then openssl compiles correctly.
