Hello,
I am also facing the same issue with path size. Can you share the
workaround what you are using for this issue?
In the /scripts/relocate_sdk.py
<https://urldefense.com/v3/__http://relocate_sdk.py__;!!AjveYdw8EvQ!JDWhGSHwH-D2E97f5wJ31g8y5hNRRKDdDRtOaybzIuFpIkRbteVvxi21IQA639Cv5fr3Aw$>/
the file name comparison is like below:
if (len(new_dl_path) >= p_filesz):
print("ERROR: could not relocate %s, interp size =
%i and %i is needed." \
% (elf_file_name, p_memsz, len(new_dl_path) + 1))
break
dl_path = new_dl_path + b("\0") * (p_filesz -
len(new_dl_path))
And, to fix the issue I made changes like below.
if (len(new_dl_path) >= 4096):
print("ERROR: could not relocate %s, interp size = %i and %i is
needed." \
% (elf_file_name, p_memsz, len(new_dl_path) + 1))
break
dl_path = new_dl_path + b("\0") * (4096 -
len(new_dl_path))
and commented below code.
#if old_size != os.path.getsize(e):
#print("New file size for %s is different. Looks like a
relocation error!", e)
#sys.exit(-1)
Do you have any clue regarding,
- Why the installation path is depending of elf headers i.e., Why
installation error when the /len(new_dl_path)/ is greater than /p_filesz/?
- Changing this comparison (len(new_dl_path) >= 4096) will impact the
installed SDK?
The 4096 comes from PATH_MAX:
|linux/limits.h|.
|#define PATH_MAX 4096 /* # chars in a path name including nul */|
|but that does seem a tad on the long side. I'd prefer a more reasonable
limit that we have actually tested, say PATH_MAX/4 (??) and a comment in the
commit log documenting the choice.|
|Finally, we do have a test that extracts the sdk in:|
| meta/lib/oeqa/sdk/testsdk.py|
|Can you review that code and use a long but fixed length path by
default so that we catch regressions? The path is set in:
sdk_dir = d.expand("${WORKDIR}/testimage-sdk/")
since len(${WORKDIR} may vary, I'd like to see code that corrects
for that and results in a fix length of PATH_MAX/4 assuming that
things work with such a long path.

|Denis? Does that make sense and what is your work-around?
