Attempting to build the module fails on Solaris 10 using perlgcc. perlgcc is a wrapper around perl to amend the Config module (since perl was built with cc but I am using gcc to compile with). $ uname -a SunOS dev17 5.10 Generic_118855-33 i86pc i386 i86pc $ which perlgcc /usr/perl5/bin/perlgcc $ ls -la /usr/perl5/5.8.4/bin/perlgcc -r-xr-xr-x 1 root bin 651 Jan 21 2005 /usr/perl5/5.8.4/bin/perlgcc $ perlgcc Makefile.PL # running Build.PL Can't locate the perl binary used to run this script in (/usr/perl5/5.8.4/bin /usr/perl5/5.8.4/bin /usr/perl5/5.8.4/bin /usr/perl5/bin /usr/local/bin /usr/bin . /usr/sfw/bin /opt/sfw/bin /opt/sfw/sbin /usr/ccs/bin /usr/local/mysql/bin) $ perlgcc -V Summary of my perl5 (revision 5 version 8 subversion 4) configuration: Platform: osname=solaris, osvers=2.10, archname=i86pc-solaris-64int uname='sunos localhost 5.10 i86pc i386 i86pc' config_args='' hint=recommended, useposix=true, d_sigaction=define usethreads=undef use5005threads=undef useithreads=undef usemultiplicity=undef useperlio=define d_sfio=undef uselargefiles=define usesocks=undef use64bitint=define use64bitall=undef uselongdouble=undef usemymalloc=n, bincompat5005=undef Compiler: cc='gcc', ccflags ='-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_TS_ERRNO', optimize='-O2 -fno-strict-aliasing', cppflags='' ccversion='GNU gcc', gccversion='', gccosandvers='' intsize=4, longsize=4, ptrsize=4, doublesize=8, byteorder=12345678 d_longlong=define, longlongsize=8, d_longdbl=define, longdblsize=12 ivtype='long long', ivsize=8, nvtype='double', nvsize=8, Off_t='off_t', lseeksize=8 alignbytes=4, prototype=define Linker and Libraries: ld='gcc', ldflags ='' libpth=/lib /usr/lib /usr/ccs/lib libs=-lsocket -lnsl -ldl -lm -lc perllibs=-lsocket -lnsl -ldl -lm -lc libc=/lib/libc.so, so=so, useshrplib=true, libperl=libperl.so gnulibc_version='' Dynamic Linking: dlsrc=dl_dlopen.xs, dlext=so, d_dlsymun=undef, ccdlflags='-R /usr/perl5/5.8.4/lib/i86pc-solaris-64int/CORE' cccdlflags='-fPIC', lddlflags='-G' Characteristics of this binary (from libperl): Compile-time options: USE_64_BIT_INT USE_LARGE_FILES Locally applied patches: 22667 The optree builder was looping when constructing the ops ... 22715 Upgrade to FileCache 1.04 22733 Missing copyright in the README. 22746 fix a coredump caused by rv2gv not fully converting a PV ... 22755 Fix 29149 - another UTF8 cache bug hit by substr. 22774 [perl #28938] split could leave an array without ... 22775 [perl #29127] scalar delete of empty slice returned garbage 22776 [perl #28986] perl -e "open m" crashes Perl 22777 add test for change #22776 ("open m" crashes Perl) 22778 add test for change #22746 ([perl #29102] Crash on assign ... 22781 [perl #29340] Bizarre copy of ARRAY make sure a pad op's ... 22796 [perl #29346] Double warning for int(undef) and abs(undef) ... 22818 BOM-marked and (BOMless) UTF-16 scripts not working 22823 [perl #29581] glob() misses a lot of matches 22827 Smoke [5.9.2] 22818 FAIL(F) MSWin32 WinXP/.Net SP1 (x86/1 cpu) 22830 [perl #29637] Thread creation time is hypersensitive 22831 improve hashing algorithm for ptr tables in perl_clone: ... 22839 [perl #29790] Optimization busted: '@a = "b", sort @a' ... 22850 [PATCH] 'perl -v' fails if local_patches contains code snippets 22852 TEST needs to ignore SCM files 22886 Pod::Find should ignore SCM files and dirs 22888 Remove redundant %SIG assignments from FileCache 23006 [perl #30509] use encoding and "eq" cause memory leak 23074 Segfault using HTML::Entities 23106 Numeric comparison operators mustn't compare addresses of ... 23320 [perl #30066] Memory leak in nested shared data structures ... 23321 [perl #31459] Bug in read() SPRINTF0 - fixes for sprintf formatting issues - CVE-2005-3962 Built under solaris Compiled at Feb 9 2006 06:26:23 %ENV: PERL="/usr/perl5/bin/perlgcc" PERL5LIB="/usr/perl5/5.8.4/lib/Sun/Solaris/PerlGcc:/usr/local/nagios/perl/lib:/usr/local/rrdtool-1.2.19/lib/perl/5.8.7/i86pc-solaris/" PERL5_OVERRIDE_CONFIG="1" @INC: /usr/perl5/5.8.4/lib/Sun/Solaris/PerlGcc /usr/local/nagios/perl/lib/i86pc-solaris-64int /usr/local/nagios/perl/lib /usr/local/rrdtool-1.2.19/lib/perl/5.8.7/i86pc-solaris/ /usr/perl5/5.8.4/lib/i86pc-solaris-64int /usr/perl5/5.8.4/lib /usr/perl5/site_perl/5.8.4/i86pc-solaris-64int /usr/perl5/site_perl/5.8.4 /usr/perl5/site_perl /usr/perl5/vendor_perl/5.8.4/i86pc-solaris-64int /usr/perl5/vendor_perl/5.8.4 /usr/perl5/vendor_perl .

Thanks Duncan, I don't have a good answer for that. If the wrapper is changing the config, then we'll see a different one when we run $^X (which is likely to break the build process.) Is this typical of solaris? (If so, I would rather they do it differently (I don't know of any precedent for using $ENV{PERL}.)) We could try to support this usage in Module::Build, but I'm afraid we'll miss something propagating it to a subprocess (and any random test or other setup code from CPAN might get it wrong too.) I think a better approach would be to set PERL5OPT (e.g. to -MConfigGCC and have ConfigGCC.pm take care of things), which is a supported and documented perl feature that will always propagate to subprocesses (except taint, but we don't build under taint.) With that, I'm thinking this is not a bug. If the PERL5OPT thing doesn't work, let's reopen it as a wishlist item. Thanks, Eric

When _perl_is_same() returns false, the two most common reasons are locale problems (the config text gets messed up) or that they're not really the same. To make sure I'm following properly, are /usr/perl5/5.8.4/bin/perl and /usr/perl5/bin/perlgcc the same perl? Symlinks or something? If so, can you verify that their Config->myconfig() output is the same as each other? -Ken

perlgcc is a small wrapper script that adds in a new directory to @INC containing a different Config.pm - the wrapper script is attached. This is because the Sun provided perl is compiled with cc (which isnt supplied by default) but i have gcc on my system (which is); modules won't compile as they try to use the same setup as perl does. The replacement config changes all the necessary vars to allow gcc to be used instead of cc. ExtUtils::MakeMaker modules can be successfully compiled and installed when using perlgcc to build them (the only time perlgcc is really required is for building modules). This becomes more of an issue when using CPAN to install modules, when dependencies use a mixture of both Module::Build and ExtUtils::MakeMaker as one set need perlgcc, and the other cannot use it. $ perl -MConfig -e 'print "$_=$Config{$_}\n" foreach(sort(keys(%Config)))' > perl.config $ perlgcc -MConfig -e 'print "$_=$Config{$_}\n" foreach(sort(keys(%Config)))' > perlgcc.config $ diff perl.config perlgcc.config 52,53c52,53 < cc=cc < cccdlflags=-KPIC --- Show quoted text

I think that reduces to: PERL5OPT="-I/usr/perl5/5.8.4/lib/Sun/Solaris/PerlGcc" I'm not seeing why the PERL5LIB isn't affecting _perl_is_same() though. Show quoted text

Are you saying "cannot use it" because of this issue or is that a deeper issue involving the compiler? Which set needs which? I notice that you're running Makefile.PL in the Module::Build distribution. Does running Build.PL give different results? --Eric

When using CPAN to install modules, $ perl -MCPAN -e 'shell' ExtUtils::MakerMaker modules fail to build, but Module::Build is ok $ perlgcc -MCPAN -e 'shell' then Module::Build fails, but ExtUtils::MakeMaker modules are ok This is a problem when dependencies of a module i am building use both schemes.

Using perl and not perlgcc with the above env var certainly seems to be working on both types of module. Getting the following warnings, but I'll see how it goes after the installs have finished (tests do seem to be passing ok) ==== Checking if your kit is complete... Looks good Have /usr/perl5/5.8.4/lib/Sun/Solaris/PerlGcc/Config.pm expected /usr/perl5/5.8.4/lib/i86pc-solaris-64int/Config.pm Your perl and your Config.pm seem to have different ideas about the architecture they are running on.

What if instead of "./Build" you do "perlgcc ./Build"? Some platforms have shebang-line problems where $^X doesn't get set correctly by the kernel and/or perl. -Ken

Ah. You've made a situation where PERL5LIB is changing between Build.PL and ./Build. To replicate this on a linux system (or osx via slight adjustment to the first line below) # mkdir /tmp/fake && perl -pe 's/(osname.*)linux/$1LiNux/' < \ $(perl -MConfig -e 'print $INC{"Config.pm"}') > /tmp/fake/Config.pm # cd /tmp && module-starter Foo && cd Foo # PERL5LIB="/tmp/fake:$PERL5LIB" perl Build.PL ... (business as usual) ... # ./Build Can't locate the perl binary used to run this script in (/usr/bin ...) Because the perl binary (not 'perlgcc') is $^X in Build.PL, that's what you're going to get for a shebang in ./Build. Thus, exporting PERL5LIB or PERL5OPT would work, but the wrapper script won't (unless it sets $^X, but my hunch says it is better to avoid that.) I'm still don't think this should be considered a bug. Do we want to try to DWIM in the face of a changing PERL5LIB (or any other env var for that matter?) What if paths were added or removed? What if the change was intentional? Seems like it makes too many cases where the magic behind the curtain could empuzzle the user. Hmm, we are restoring @INC in the ./Build script -- but we're not propagating that to the `perl` command in _perl_is_same(). If you stick 'warn $INC{"Config.pm"}' on the end of that @cmd, you'll see this. Thus, I think we actually need to be removing some DWIM rather than adding it (and I think this issue illustrates that.) (Note: the ./Build process is seeing "/tmp/fake/Config.pm", but _perl_is_same() is seeing the stock config. You can observe this by adding the following line just after 'use Module::Build' in the ./Build script (and modifying @cmd in _perl_is_same() of Base.pm) BEGIN {warn "inc ", $INC{'Config.pm'}}; ) --Eric

Sounds like this is solved by $PERL5OPT. The question of whether we're "doing the right thing" with @INC and $PERL5LIB has been moved to ticket #31566.
