在Solaris 10 Sparc上将Perl编译为64位

Question

I am trying to compile perl 5.22.2 on Solaris , sparc, as 64 bit (os is 64 bit). It compiled and linked fine as a 32 bit binary, now I have added the -m64 flag to CFLAGS and LDFLAGS , and I am getting the following error:

...skipping...

make: *** [perlio.o] Error 1

For reference, i have extracted the mentioned lines from perlio.c :

3400:   STDCHAR *eptr = (STDCHAR*)PerlSIO_get_ptr(s);
3408:       if ((STDCHAR*)PerlSIO_get_ptr(s) != --eptr || ((*eptr & 0xFF) != ch)) {
3531:    return (STDCHAR*)PerlSIO_get_base(stdio);
3538:    return PerlSIO_get_bufsiz(stdio);
3547:    return (STDCHAR*)PerlSIO_get_ptr(stdio);
3554:    return PerlSIO_get_cnt(stdio);
3575:   PerlSIO_set_ptr(stdio, ptr); /* LHS STDCHAR* cast non-portable */
3594:    PerlSIO_set_cnt(stdio, cnt);

It looks like its doing something strange with the source, notice how _ptr is treated as a seperate entity, whereas the function is called PerlSIO_get_ptr . Looks like its being cut off.

Anyone any idea what is going on here? FYI using something like perlbrew is not an option, I need to compile this myself :(.

It turns out I needed to add the -Duse64bitall flag to the Configure script. So finally I was able to build with

export CFLAGS=-m64 # not sure if really nessessary - just what I did
./Configure -Duse64bitall -Dcc=gcc -d
make

For my setup I also need some more libraries, so this is a rather simplified version. However it solved the problem described in this post.
