Not yet, but I am still working on that problem ... :-)
I got puzzled by a different problem related to Perl && Inline && AIX :-(
I found out that every time I run an Inline related script I got the
code recompiled. To make a long story short, it turned out, that the
suffix for dynamic perl libraries under AIX is set to "a" (see
perl-source/hints/aix.sh) and therefore I got the following information:
<-----------------------Information Section----------------------------------->
Information about the processing of your Inline C code:
Your source code needs to be compiled. I'll use this build directory:
/tmp/blib_I/main_C_example001_pl_e50a703a59502715d0f051e719b09335/
and I'll install the executable as:
/tmp/blib_I/lib/perl5/site_perl/5.005/aix/auto/main_C_example001_pl_e50a703a59502715d0f051e719b09335/main_C_example001_pl_e50a703a59502715d0f051e719b09335.a
The following Inline C function(s) have been successfully bound to Perl:
void greet(char * name)
<-----------------------End of Information Section---------------------------->
Watch the "a" at the end of the path of line next to
"and I'll install the executable as:"
But when you check the output of all involved make steps, there is
nothing like a suffix "a". It always says "so". So I guess at some
certain point the "library.so" should have been {moved,copied} to
"library.a". But that step never happened. I have attached the
corresponding output files.
When I changed the line
so='a'
to
so='so'
in /usr/local/lib/perl5/5.00502/aix/Config.pm then everything worked
fine and when I run a script more than once the previously compiled
code was used.
Therefore I assume that Inline was searching for a library with the
suffix "a" but could not find such a beast and therefore decided to
compile the code again.
Cheers,
Norbert
