Update: My solution here is not cross-platform. See AnonyMonk's post Re^2: Makefile.PL Question for details as to why. `# original post` This might be very far off, so I'll let other Monks intervene if this is a bad idea, but I just tried adding `symlink('apps', 't');` to the top of a `Makefile.PL` of one of my modules, and things seemed to go ok: `$ cat Makefile.PL # Note: this file was auto-generated by Module::Build::Compat version +0.4214 require 5.006; use ExtUtils::MakeMaker; symlink('apps', 't'); # <-- * I added this line * WriteMakefile ( 'PL_FILES' => {}, 'EXE_FILES' => [], 'NAME' => 'Devel::Examine::Subs', 'INSTALLDIRS' => 'site', 'VERSION_FROM' => 'lib/Devel/Examine/Subs.pm', 'PREREQ_PM' => { 'File::Find' => 0, 'Data::Dumper' => 0, 'Tie::File' => 0, 'Carp' => 0, 'Test::Trap' => 0, 'Test::More' => 0, 'PPI' => 0 } ) ;` [download] Output: steve@spek ~/devel $ hg clone https://spek@bitbucket.org/spek/devel-ex +amine-subs ... steve@spek ~/devel $ cd devel-examine-subs/ steve@spek ~/devel/devel-examine-subs $ mv t apps steve@spek ~/devel/devel-examine-subs $ vi Makefile.PL # added the said symlink code here steve@spek ~/devel/devel-examine-subs $ perl Makefile.PL Checking if your kit is complete...

Thanks... I've read the info that you've provided, and point taken. It's not often I have to think cross-platform.	[reply]

How to specify this change in my Makefile.pl file. See PMLIBDIRS of ExtUtils::MakeMaker, PM of ExtUtils::MakeMaker... because if i leave it as is no installation is possible. What do you mean by this?	[reply]

I appologize for being so cryptic. It is obvoius there was not enoug information in my post. so allow my to start from he top. my Makefile.PL looks like this : `use ExtUtils::MakeMaker; WriteMakefile( NAME => 'LC::Mod', VERSION_FROM => 'src/lib/LC/Mod.pm', dist => { 'COMPRESS' => 'gzip' }, PREREQ_PM => { # Require Getopt::Long at least 2.42 "Getopt::Long" => '2.42', # Require any version of File::Slurp "File::Slurp" => 0, } );` [download] if my source tree looks like the first case illustrated in the first figure above, when I execute : perl Makefile.PL make make test sudo make install everything is installed properly into my `/usr/local/lib/perl/5.14.2/auto/LC/Mod/...` [download] directory. but if i set my source tree as in the second figure instalation does not copy my *.pm files into its required folder thus when i execute my application which uses this module i get a classic `Can't locate LC/Mod.pm in @INC (@INC contains: /etc/perl /usr/local/li +b/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/ +perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_per +l .) at t/LC.pl line 26.` [download] also if i do the smylinks i run into the same problem.

Re^2: Makefile.PL Question by stevieb (Canon) on Sep 04, 2015 at 15:51 UTC
Update: Darn it, I don't think this will work either, because `File::Copy::Recursive` is not in `corelist`, and I haven't found anything else in core that can copy/move directories (yet). I'd still like to know if this fixes your issue though, just to satisfy my own curiosity. End update I'm only assuming that these issues are related to the `t/` directory not being in the right place, but I'm not sure. Instead of my earlier note about using `symlink()` which is not cross-platform, can you try to copy the directory? (tested on nix and win): `use ExtUtils::MakeMaker; use File::Copy::Recursive qw(dircopy); dircopy('apps', 't'); WriteMakefile ( 'PL_FILES' => {}, 'EXE_FILES' => [], 'NAME' => 'Devel::Examine::Subs', 'INSTALLDIRS' => 'site', ...` [download] Does that help?

Hi stevieb, you can move (rename) directories with File::Copy: `#!/usr/bin/perl use strict; use warnings; use File::Copy 'mv'; mkdir( 'Project/src' ) or die $!; mv('Project/lib', 'Project/src/lib' ) or die $!; mv('Project/t', 'Project/src/apps' ) or die $!; __END__` [download] $ ls -lR Project total 0 -rw-r--r-- 1 nick staff 0 Sep 4 09:20 Makefile.PL drwxr-xr-x 3 nick staff 102 Sep 4 09:21 lib drwxr-xr-x 3 nick staff 102 Sep 4 09:21 t Project/lib: total 0 -rw-r--r-- 1 nick staff 0 Sep 4 09:21 Modul.pm Project/t: total 0 -rw-r--r-- 1 nick staff 0 Sep 4 09:21 test $ [download] $ perl 1141027.pl $ [download] `$ ls -lR Project total 0 -rw-r--r-- 1 nick staff 0 Sep 4 09:20 Makefile.PL drwxr-xr-x 4 nick staff 136 Sep 4 09:26 src Project/src: total 0 drwxr-xr-x 3 nick staff 102 Sep 4 09:21 apps drwxr-xr-x 3 nick staff 102 Sep 4 09:21 lib Project/src/apps: total 0 -rw-r--r-- 1 nick staff 0 Sep 4 09:21 test Project/src/lib: total 0 -rw-r--r-- 1 nick staff 0 Sep 4 09:21 Modul.pm` [download] The way forward always starts with a minimal test.

Re^2: Makefile.PL Question ( ExtUtils::MakeMaker PMLIBDIRS sub MY::libscan ) by Anonymous Monk on Sep 05, 2015 at 08:11 UTC
What am I missing?? A good reason to use "src" instead of "lib" A good reason you're avoiding PMLIBDIRS or PM option? Seriously, do you have me on ignore? Allergic to manuals documented solutions? :P symlink or copying files yourself misses the point of having a toolkit like MakeMaker with conventions A try Read more... (2 kB) Gee, flaunting convention isn't the smartest idea, I end up with SAUCE in the module tree Luckily i've read PMLIBDIRS docs and I know what to do, append to Makefile.PL and I get Read more...

I am so sorry.. i have no idea how a mannaged to miss your post. "A good reason to use "src" instead of "lib" " , The reason is consistency due to general project requirenmants. so ... Thnx ++	[reply]
Re^2: Makefile.PL Question by Anonymous Monk on Sep 04, 2015 at 17:27 UTC
Does the message about missing LC::Mod actually appear duirng "make test"? My guess is so because "t/LC.pl" is mentioned. But that could/should not be if you had replaced "t" with "src/apps"?.	[reply]
Re^3: Makefile.PL Question by Anonymous Monk on Sep 04, 2015 at 17:35 UTC
Ok, perl runs tests in default, implicit "t" directory. Apparently that can be changed by setting TESTS.	[reply]
