G'day All,

We're just updating from honister to kirkstone branch and run into
an issue with libstdc++. We're targeting a 32 bit arm device.

is_empty throws with "filesystem error: cannot check if file is empty: Operation not supported"
when called on an empty directory.

tracing this status is returning fs::file_type::unknown which looks to result from stat returnung EOVERFLOW.
Which appears to be related to 64 / 32 bit file size limits.

We are compiling our code with: -D_FILE_OFFSET_BITS=64


It does look like the builds are linking things slightly differently.

Hello there,

It isn't due to EOVERFLOW but make_file_type function in libstdc++-v3\src\filesystem\ops-common.h always returns file_type::unknown.
It's because _GLIBCXX_HAVE_S_ISREG isn't defined.
I found HAVE_S_ISREG at libstdc++-v3/config.h isn't set properly.

It's caused by a configure failure below to tell if S_ISREG exists on the target.
gcc/arm-emit-linux-gnueabi/11.3.0/ld: error: tmp-glibc/work/cortexa9t2hf-neon-emit-linux-gnueabi/gcc-runtime/11.3.0-r0/dummylib/libstdc++.so: file is empty
collect2: error: ld returned 1 exit status
configure:15686: $? = 1

It complains dummylib/libstdc++.so is empty, configure failed then wrongly considered S_ISREG doesn't exist.
This seems related to the following commit.
https://github.com/openembedded/openembedded-core/commit/34b0edb0d3120c32063ff7e3dd52be20d60401d5

Reverting this commit rectifies this issue but not sure what's the proper fix?
Any help appreciated.

Thanks,
Mori

There is some piece we're still not understanding. I had a look at my
local build (master so gcc 12.1) and I see HAVE_S_ISREG is set
correctly, I don't see any "file is empty" message.

Are you able to reproduce this on master? Which linker are you using?

Cheers,

Richard

G'day Richard,

I've update to master and tried this. Still get a "file is empty" error during configure. See log snippet below.


Tried to capture the ld version here:

It does thanks. It confirms you're using the gold linker which allowed
me to reproduce (I was trying with the default bfd). I think this small
change will fix it:

G'day Richard,

Thanks, can confirm that this fixes the problem. Our tests all passed.
Will you submit this as a patch?
Affects us on kirkstone, as well as master branch.
