[wget, wget2] /usr/bin/ld: /usr/bin/ld: DWARF error: invalid or unhandled FORM value: 0x25
The builds for wget and wget2 fail since a while because of this error.
My guess is that clang emits dwarf5 data while ld (version 2.34) can't handle it.
Maybe either update ld in the docker image or let clang emit dwarf4!?
Any other suggestion?
The dwarf error seems to be a symptom, but not the cause of the build failure. I think the build failure is
multiple definition ofmpn_cnd_add_n
See https://github.com/google/oss-fuzz/pull/11839
I think that this has something to do with this stuff here:
if [[ $CFLAGS = *sanitize=memory* ]]; then
GNUTLS_CONFIGURE_FLAGS="--disable-hardware-acceleration"
NETTLE_CONFIGURE_FLAGS="--disable-assembler --disable-fat"
fi
the if check only passes when we use memory sanitizer. I tried to compile nettle with the --disable-assembler --disable-fat and it worked good. I modified the build.sh to have this instead:
if [[ $CFLAGS = *sanitize=memory* ]] || [[ $CFLAGS = *sanitize=address* ]] || [[ $CFLAGS = *sanitize=undefined* ]]; then
GNUTLS_CONFIGURE_FLAGS="--disable-hardware-acceleration"
NETTLE_CONFIGURE_FLAGS="--disable-assembler --disable-fat"
fi
and it seems to compile nettle all fine.
After compiling nettle it tries to compile gnulib (I think) and I get these errors:

but maybe that should be opened in another issue?
I fixed the build.sh script such that it now atleast compiles. Definitely not pretty, but atleast it compiles I have documented my fixes here in a blog post (I wrote these notes while I was debugging): https://personnumber3377.github.io/projects/improving_wget_options_fuzzer.html#final-thoughts and here is the final diff patch to the root of oss-fuzz as a file: https://personnumber3377.github.io/projects/patch.diff . I had to modify the helper.py script to have the -detect_leaks=0 option always enabled, because I didn't know how to enable it through the helper.
@personnumber3377 Thanks for the detailed write-up! I'll go through it and try to figure out why some things failed for you (e.g. the gnulib failure come quite unexpected to me).
@rockdaboot yeah, I couldn't find anything on the internet on why it failed for mean. It may be because of the different versions of autotools or something like that. I don't really know that much about how to actually use autotools, so I am quite clueless in that. Also about adding my code to the wget project: Is there any easier way to do it other than through FSF? I don't really feel like going through all of the paperwork. Is it possible to contribute to the wget project, but I still reserve copyright of those changes which I did? (I assume that is either not possible or quite complex to do.) In FSF do I just send the email to [email protected] with the information which you listed? I have never before contributed to open source, so I don't really know how this works. Also does FSF also include future changes which I may make? I have heard of copyright disclaimers, where I just sign it and after that I no-longer have copyright over it: https://www.gnu.org/prep/maintain/html_node/Copyright-Papers.html .
@personnumber3377 After testing, I opened https://gitlab.com/gnutls/gnutls/-/issues/1552.
But I also found a work-around for wget2. And likely that it will also work for wget (I'll create a PR soon).
Let's talk about code contributions either on a private channel or on the public mailing list [email protected], it's slightly OT here.
Fixed the wget build in https://github.com/google/oss-fuzz/pull/11998.
Indeed, the message "/usr/bin/ld: /usr/bin/ld: DWARF error: invalid or unhandled FORM value: 0x25" was misleading and seems to be plain wrong. Closing.
