"cc1: error: invalid option 'tune=i686'" while installing Perl modules via CPAN
For some reason I am no longer able to install Perl modules via CPAN. I'm getting a consistent error message everytime I try to install something, regardless of what it is (which leads me to think it's a library issue), and Google turns up absolutely nothing useful that I've found. For instance, I'm trying to install the Gtk module to build a front-end for a program I'm working on. This is what takes place:

/usr/X11R6/include  -I./Gtk -I./build -fno-strict-aliasing -pipe -Wdeclaration-after-statement -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -march=i486 -mtune=i686  -DVERSION=\"0.7000\" -DXS_VERSION=\"0.7000\" -fPIC "-I/usr/lib/perl5/5.8.8/i486-linux/CORE"  -DPERL_POLLUTE -DGTK_HVER=0x01020a build/GtkDefs.c
cc1: error: invalid option `tune=i686'
cc1: error: unrecognized option `-Wdeclaration-after-statement'
make: *** [build/GtkDefs.o] Error 1
  /usr/bin/make  -- NOT OK
Running make test
  Can't test without successful make
Running make install
  make had returned bad status, install seems impossible


I'm then returned to a cpan> prompt (like above) and that's that. I tried using cpanp which I've read works a little better, but it gets to "Installing Gtk..." and freezes. Any help with this is greatly appreciated.

have you tried -
1) checking / rebuilding your config file OR
2) installing module (which is failing as above ) by hand?

On 1) : for CPAN , locate
in my setup its at $HOME/.cpan/CPAN
is there a value for the hash key 'make_arg' ? (just a guess)

however I'm confused about a few things: you also tried cpanp (front end to CPANPLUS)? Did you install that
successfully via CPAN? (And i assume CPANPLUS would have also been installed). And, if CPANPLUS was installed
, could you have made the same error in the config setup (maybe my hunch above is totally off)?

Regarding 2)
How about simply downloading a module, say IO::Prompt, and then going to the build directory and installing
by hand. Usually it's perl Makefile.PL; make ; su -c 'make install' but follow the directions per the README.
(there's also the newer build method).

I've rebuilt the config file from within cpan, and I've checked it for 'tune', it's not present. Just in case though, here is my

As you've probably guessed, I have scuzzy as a member of the cpan group ;)
It is quite curious, now that you mention it, that I was able to build cpanp. I've just tried building the Term::ReadKey module (a dependency of IO::Prompt), and it failed with this (the same errors as with CPAN):

[scuzzy@slackdell /home/scuzzy/tarball/TermReadKey-2.30]$ make test

I just remembered that I upgraded gcc a couple of weeks ago (had to because I upgraded KDE) and haven't tried to install a Perl module since. Perhaps this is what's causing it - a problem with gcc? If it helps any: gcc is working fine - I can still compile C applications. I've done a few searches though, and can't find anything related...

jxi 02-21-2006 04:03 PM

a few more things to try -

which make does perl use (should be same as in Config above!):
perl -V:make

run this perl script:


#!/usr/bin/perl -w
@keys  = keys %ENV;
@values = values %ENV;
while (@keys) {
    print pop(@keys), '=', pop(@values), "\n";

pipe it into more, less or redirect to a file. Check the environmental settings.

as for a problem with gcc, it don't think gcc gets involved in the make step when the makefile was generated by perl, e.g.,

perl Makefile.PL #builds a makefile for the perl interpreter.#

#make by itself is compiler/interpreter independent#

instead of using the make, try with Module::Build from cpan.

(sorry i can;t remember if it needs `make` to be installed itself)


Tinkster 02-21-2006 04:59 PM

Did you play around with .bashrc and have set some stuff
in CFLAGS that the compiler doesn't like?


scuzzman 02-22-2006 09:17 AM

It doesn't appear I have that, Tink... The only line in my ~/.bashrc is my "export PS1=..." line... TBH, I don't know what this file is for... or any of the bash* files in my ~.
As for CFLAGS, there is no definition for that, and I don't know where I would find one (didn't adjust it - I'm sure of that).

As for the above Perl script and command, here are the results:

[scuzzy@slackdell /home/scuzzy/devel/perl]$ ./
LS_OPTIONS= --color=auto -F -b -T 0
PS1=[\u@\h $PWD]$
[scuzzy@slackdell /home/scuzzy/devel/perl]$ perl -V:make
[scuzzy@slackdell /home/scuzzy/devel/perl]$

It doesn't have a CFLAGS defined, nor is there anything in there about make...

Edit: just installed Module::Build with a typical "perl Makefile.PL && make && sudo make install"

jxi 02-22-2006 09:29 AM

Excellent! Now, in a downloaded package's folder, you can use:
perl Build.PL
./Build test
./Build install

(perhaps you've already tried it!)

scuzzman 02-23-2006 12:26 PM

Sorry for the delay, had a few things happening... This is what takes place though:
When I cd to a package I've downloaded and type 'perl Build.PL' this happens:

[scuzzy@slackdell /home/scuzzy/tarball/TermReadKey-2.30]$ perl Build.PL
Can't open perl script "Build.PL": No such file or directory

So, I thought I had to specify the Build.PL in the directory of the Module-Build, so I did this:

[scuzzy@slackdell /home/scuzzy/tarball/TermReadKey-2.30]$ perl ../Module-Build-0.2611/Build.PL
Checking whether your kit is complete...
Looks good
 * Optional prerequisite Module::Signature isn't installed
 * Optional prerequisite ExtUtils::ParseXS isn't installed
 * Optional prerequisite ExtUtils::CBuilder isn't installed
ERRORS/WARNINGS FOUND IN PREREQUISITES.  You may wish to install the versions
 of the modules indicated above before proceeding with this installation.

Feature 'YAML_support' disabled because of the following prerequisite failures:
 * Prerequisite YAML isn't installed

Can't open 'lib/Module/' for version: No such file or directory at /usr/lib/perl5/site_perl/5.8.8/Module/Build/ line 623.
[scuzzy@slackdell /home/scuzzy/tarball/TermReadKey-2.30]$

There is no Build.PL in the TermKey directory... What am I missing?

jxi 02-23-2006 09:05 PM

My omission, sorry :rolleyes: Module::Build is relatively new and not all packages can take advantage of it. IO::Prompt is an example of one with it: what I wanted is just that you can prove that it's possible to install perl modules on your system, then try to work back and find the reason for that tune=i686 error (if it's still a problem)...

Sounds like

scuzzman 02-24-2006 06:10 AM

What's with the "cc1" in the error message on the make? Does that mean it's using gcc or cc (which would make sense if the modules are written in C and not Perl - especially in the case of Gtk or Gnome modules)? If so, it could be a CFLAGS error as Tink pointed out before, but I can't, for the life of me, figure out where this is set. Where would that "tune=i686" come from, and is it possible to just take it out? Also, the more I look, I'm seeing -mtune=i686 used, not -tune...

scuzzman 02-26-2006 12:20 PM

Got the problem fixed. Downgraded from Perl v5.8.8 to Perl v5.8.7 and it fixed it strangely enough. Thanks for both your help though.

jxi 02-26-2006 04:29 PM

glad to hear it. I didn'nt have much more to offer.
But I just noticed (checking my Perl version, which is 5.8.7)
perl -V

under Compiler: there's settings like
cc='cc', ccflags =' ...

and so on. Maybe those were misconfigured previously.

hydroxyblue 08-21-2006 10:30 PM

I found I got the same error "tune=686" for perl 5.8.8 (slackware 10.0 with various 10.0 CD installed packages)

This was on a new install of 10.0 last night on a vmware partition.

I 'removepkg perl' to remove bundled version.

I downloaded latest perl from slackware/pb (5.8.8) and:
installpkg perl*
perl -MCPAN -e shell
> install Bundle::CPAN

I got the error during numerous cc1's throughout the session, and it ultimately failed.

I'd forgotten to install the /l packages, once I did that, the error disappeared.

So the issue might just be a missing library package. I'll see if I can find the offending one, but since I 'installpkg /l/*.tgz' I'm not sure which one it is, and it may be difficult to find.

I suppose we could check the perl 5.8.8 prerequisite libraries... :)
