cannot compute suffix of object files: cannot compile: -a64 unsupported

cannot compute suffix of object files: cannot compile: -a64 unsupported

[dellair jie]

Folks,

I am compiling GCC 4.4.5 on AIX 6.1 with xlc 10.1.

GMP, MPFR, MPC are compiled because we have no root control over the server.

Configuration options are as following.

Would be appreciated if anyone can shed some lights on what went wrong.

PS: a64 option is found nowhere, which is really weird.

config.log:
Configured with: /gcc/configure --prefix=/AIX32 --enable-static

Then you should probably build then in-tree, not install them
separately. See http://gcc.gnu.org/wiki/InstallingGCC

Have you read http://gcc.gnu.org/wiki/FAQ#configure_suffix ?

If you follow the instructions at
http://gcc.gnu.org/wiki/InstallingGCC it will probably solve your
problem.

Re: cannot compute suffix of object files: cannot compile: -a64 unsupported

[dellair jie]

Dear Jonathan,

Thanks for the reply and information shared.

We are not able to compile the GMP/MPFR/MPC libraries via prerequisite
script as the server is not connected to internet either. Hence we can
only compile them separately.
The libraries we compile are static libraries, and after the
compilation, a "make check" has been done in order for accuracy.

I did follow your guide to check the config.log under sub-directory,
in this case libgcc, and the log was attached in first email.
It failed at "Fatal error: -a64 unsupported" and it is very confusing
cause there's nowhere to find the a64 option in command/arguments.

Could it be incompatibility of AIX6.1 and GCC 4.4.5 and XLC 10.1?

Thanks,
Dellair

That's not true, you don't need to use the download_prerequisites
script, it just makes it easier. You can still put the sources in the
GCC tree manually to build them in-tree.

OK, building them static avoids the problem I thought you were having
(but it's still easier to build them in-tree).

It also says the option -q32 is not recognised. GCC should not be
trying to use arguments it doesn't recognise, so that suggests the
argument came from your configuration.  Do you have any environment
variables set that contain -q32?  e.g. CFLAGS?  What does this show?
env | fgrep q32

Re: cannot compute suffix of object files: cannot compile: -a64 unsupported

[dellair jie]

Hello Jon,

Regarding the q32 option, I think it is a default behavior of xlc
compiler, it automatically adds q32 to build 32 bit objects.
I added one more option "--disable-multilib", and the build seems to
go further then stopped at: Permission denied to
/usr/local/include/time.h

In fact, the correct local include directory is: /usr/include instead
of /usr/local/include, any idea how we can specify it for compilation?
I just added "LOCAL_INCLUDE_DIR" variable to the build, and it is still ongoing.
What do you think adding the option "-DLOCAL_INCLUDE_DIR=" to CFLAGs
in case it stopped on the same error?

Regards,

But the option is being added to a gcc command, not xlc.

You might need to look earlier in libgcc/config.log for other relevant errors.

It will automatically look in /usr/include

The error suggests it is trying to also look in /usr/local/include but
doesn't have permission to.

[dellair jie]

Thanks Jon,

Regarding the "permisison denied" error, I have added
"-DLOCAL_INCLUDE_DIR" and setup the environment variable to
/usr/include folder.
However, I am still getting it in config.log.

Any ideas on how to get this solved?

Our environment is setup like:
All standard head files are under /usr/include
The /usr/local/include exist but only readable to root.

I'm not sure what you've done here. It would help to show the exact
commands you used.

GCC cannot be used if one of the directories in its search path is not readable.

Have you tried using the --with-local-prefix=/usr configuration option?
See http://gcc.gnu.org/install/configure.html

You are a saver!!!

The rebuild works like magic! :)
