bear::func_test failed 7 tests (3.1.4) about bear HOT 8 OPEN

Hey @DarthGandalf ,

thanks for the report. What I have noticed from the logs, all the failed tests are involving to compile and link a program. (Other tests are usually stops at compiling, but these are involving linking too.) And that is failing with the message:

collect2: fatal error: cannot find 'ld'

So, I am wondering if the ld is not available in the environment where the test are running? Or anything special happens with the environment variables that make the compiler fail to execute the linker? (My experience that gcc is sensitive about the environment variables to find other tools it executes.)

from bear.

yeah, /usr/bin/ld exists

from bear.

Can you show me what the gcc -print-prog-name=ld prints? Or what the gcc -v prints out?

thanks!

Correct me if I am wrong, but is the path /usr/lib/gcc/x86_64-pc-linux-gnu/13/../../../../x86_64-pc-linux-gnu/bin/ld resolves to /usr/x86_64-pc-linux-gnu/bin/ld? So, it looks like gcc is looking for the linker in /usr/x86_64-pc-linux-gnu/bin and not in /usr/bin. Is that correct reading of that?

from bear.

I guess... And it has ld there.

$ ls -l /usr/x86_64-pc-linux-gnu/bin/ld
lrwxrwxrwx - root 23 мая 23:08 /usr/x86_64-pc-linux-gnu/bin/ld -> /usr/x86_64-pc-linux-gnu/binutils-bin/2.42/ld

$ ls -l /usr/x86_64-pc-linux-gnu/binutils-bin/2.42/ld
.rwxr-xr-x 979k root 21 мая 01:44 /usr/x86_64-pc-linux-gnu/binutils-bin/2.42/ld

$ /usr/x86_64-pc-linux-gnu/binutils-bin/2.42/ld --version

That is the same ld which /usr/bin/ld symlinks to, through several steps

lrwxrwxrwx - root 23 мая 23:08 /usr/bin/ld -> x86_64-pc-linux-gnu-ld
lrwxrwxrwx - root 23 мая 23:08 /usr/bin/x86_64-pc-linux-gnu-ld -> /usr/x86_64-pc-linux-gnu/bin/ld

The GCC documentation about collect2 behavior to resolve the ld. I don't truly understand why it does not find the /usr/bin/ld one.

To note here...

$ cat /tmp/main.c 
#include <stdio.h>

int main() {
    return 0;
}
$ /usr/bin/gcc /tmp/main.c
$ env - /usr/bin/gcc /tmp/main.c

compilation terminated.
