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.
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?
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:
