Iam linking C/C++ lib with Perl h2xs XSUBs.
I have done the following:.
1. Create a new directory called Mytest2. In the Mytest2 directory, create another directory called mylib,..
2. Here we'll create some files that will generate a test library. These will include a C source file and a header file. We'll also create a Makefile.PL in this directory..
use ExtUtils::MakeMaker;
$verbose = 1;
WriteMakefile(
NAME => 'MyTest::mylib',
SKIP => qw(all static static_lib dynamic dynamic_lib),
clean => {'FILES' => 'mibmylib$(LIB_EXT)'},
);
sub MY::top_targets {
'
#all :: static
#pure_all ::static
static :: libmylib$(LIB_EXT)
libmylib$(LIB_EXT): $(O_FILES)
$(AR) cr libmylib$(LIB_EXT) $(O_FILES)
$(AR) -nologo -out:libmylib$(LIB_EXT) $(O_FILES)
';
}
3. Then I do and h2xs c:\per\bin> h2xs –O -n Mytest2 ./Mytest2/mylib/mylib.h
4.I get Makefile.pl generated from the above execution
5. Now I need to specify the subdirectory mylib that generates library in it.
I need to specify 'MYEXTLIB'
=> 'mylib/libmylib$(LIB_EXT)', in the Makefile.pl
use 5.010000;
use ExtUtils::MakeMaker;
# See lib/ExtUtils/MakeMaker.pm for details of how to influence
# the contents of the Makefile that is written.
WriteMakefile(
NAME => 'Mytest2',
VERSION_FROM => 'lib/Mytest2.pm', # finds $VERSION
PREREQ_PM => {}, # e.g., Module::Name => 1.1
($] >= 5.005 ? ## Add these new keywords supported since 5.005
(ABSTRACT_FROM => 'lib/Mytest2.pm', # retrieve abstract from module
AUTHOR => 'A. U. Thor') : ()),
LIBS => '', # e.g., '-lm'
DEFINE => '', # e.g., '- DHAVE_SOMETHING'
INC => '-I.', # e.g., '-I. - I/usr/include/other'
'MYEXTLIB' => 'mylib/libmylib$(LIB_EXT)',
# Un-comment this if you add C files to link with later:
OBJECT => '$(O_FILES)', # link all the C files too
);
sub MY::postamble {
'
$(MYEXTLIB): mylib/Makefile
cd mylib && $(MAKE) $(PASSTHRU)
';
}
6. Fix the MANIFEST file so that it accurately reflects the contents of our extension
mylib/Makfile.PL
mylib/mylib.h
mylib/mylib.c
7.Also did relvant changes in .Xs file and .Pm file.
8.In the cmd prompt I execute Perl Makefile.pl
9.when I say nmake on the cmd prompt I get the following error msg:
C:\Perl\bin\MyTest2>perl Makefile.PL
Checking if your kit is complete...
Looks good

Stop.
The error seems to be in the makefile which I am not able to debug.
Can u please let me know where I m going wrong in the Makefile
