FIO on AIX 7.2 giving "cc1: unrecognized option `-Wdeclaration-after-statement'" while compiling

[tdinil]

Hello,

I have a requirement to run FIO on AIX 7.2 TL3 SP3(7200-03-03-1914). While compiling the source, i am getting below error. Any help to fix this is appreciated.

Thanks, Dinil

[tdinil]

the issue is seen with "gmake"

FIO_VERSION = fio-3.19 CC crc/crc16.o cc1: unrecognized option `-Wdeclaration-after-statement' gmake: *** [crc/crc16.o] Error 1 [12:16 PM root@s922-aix03 /fio-master]:

Does it build if you just remove -Wdeclaration-after-statment from the Makefile?

[tdinil]

It gives me gmake: *** [crc/crc32c-arm64.o] Error 1

I don't have access to AIX anymore, so can't really help much there. What compiler are you using? The parse error in system headers seem odd...

Hello,

Its the xlC

How did configure get this:

Compiler gcc

? I'm not sure fio has every supported non-gcc like (which I think these days means gcc or clang) compilers though... @axboe?

[sitsofe]

(Mentioning @mperzl for comment because they have mail mentioning fio AIX work)

[tdinil]

The compiler I used on AIX came default with the AIX OS installation. Nothing was done additionally.

[sitsofe]

@tdinil as mentioned, fio only supports compilation with gcc/clang (or compilers that implement a similar enough set of features to them) so if you're trying to force it to run with something else that's not supported. It does look like gcc was found but since you're not sure about this there's not much more help I can give (I've never used AIX and have no access to it).

About the only thing I can suggest is that you look at how Michael Perzl gets fio to compile in his AIX RPM packages. See http://www.perzl.org/aix/ (and for example)ftp://www.oss4aix.org/SPECS/fio-3.15-1.spec which I note references ftp://www.oss4aix.org/patches/fio-3.15-aix.patch ).

Let us know how you get on - if it really doesn't work we should change the documentation to no longer mention AIX...

Closing due to lack of reply from reporter. If this issue is still happening with the latest fio (see https://github.com/axboe/fio/releases to find out which version that is) please reopen. Thanks!
