Crashes at argument parsing, WinDbg log attached.
This patch works fine with meson=0.49.
I was able to execute the 'helloworld' app.
When I tried to build with meson=0.52 it failed with the error:
[9/25] Linking target lib/librte_kvargs-20.0.dll.
FAILED: lib/librte_kvargs-20.0.dll
clang @lib/librte_kvargs-20.0.dll.rsp
clang: error: no such file or directory: '/OPT:REF'
Fixed this error with the patch you sent before.
were able to execute parsing:
$ ./build/examples/dpdk-helloworld.exe -l 4-8
EAL: Detected 20 lcore(s)
EAL: Detected 2 NUMA nodes
hello from core 5
hello from core 6
hello from core 7
hello from core 8
hello from core 4
Not completely sure, if this could be the reason for the crash.
The crash does not happen with any arguments, "-l 4-8" works fine as do
"-cf" and "-v", but "--log-level=eal:8" crashes reproducibly. I assume
application should not crash on invalid options, but report an error and exit.
For the reference, I applied your patchset to the latest dpdk:master.
Z:\>build\native\clang\examples\dpdk-helloworld.exe
EAL: Detected 4 lcore(s)
EAL: Detected 1 NUMA nodes
OK, no lcores specified.
Z:\>build\native\clang\examples\dpdk-helloworld.exe -cf
EAL: Detected 4 lcore(s)
EAL: Detected 1 NUMA nodes

OK, 4 lcores enabled.

Attaching the build log, but I don't think it matters, it's something with
getopt implementation or it's use, judging by stack trace.
Thanks for the detailed log.
There was bit size issue in getopt file. We fixed the issue.
Please try v8 and let us know.
P.S. I can also see "--syslog" option in the help message, you should
probably hide it via #ifndef, as you did with said option handling.
Incorporated in v8. Thanks
