在Solaris 10 Sparc上將Perl編譯為64位

Question

我正在嘗試在Solaris sparc perl 5.22.2編譯為64位（操作系統為64位）。 它作為32位二進制文​​件進行了編譯和鏈接，現在，我將-m64標志添加到CFLAGS和LDFLAGS ，並且出現以下錯誤：

...skipping...
perlio.c:3400: error: structure has no member named `_ptr'
perlio.c:3408: error: structure has no member named `_ptr'
perlio.c: In function `PerlIOStdio_get_base':
perlio.c:3531: error: structure has no member named `_base'
perlio.c: In function `PerlIOStdio_get_bufsiz':
perlio.c:3538: error: structure has no member named `_cnt'
perlio.c:3538: error: structure has no member named `_ptr'
perlio.c:3538: error: structure has no member named `_base'
perlio.c: In function `PerlIOStdio_get_ptr':
perlio.c:3547: error: structure has no member named `_ptr'
perlio.c: In function `PerlIOStdio_get_cnt':
perlio.c:3554: error: structure has no member named `_cnt'
perlio.c: In function `PerlIOStdio_set_ptrcnt':
perlio.c:3575: error: structure has no member named `_ptr'
perlio.c:3594: error: structure has no member named `_cnt'
make: *** [perlio.o] Error 1

作為參考，我從perlio.c提取了上述行：

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);

看起來它對源代碼做了一些奇怪的事情，請注意_ptr如何被視為單獨的實體，而該函數稱為PerlSIO_get_ptr 。 看起來像它被切斷了。

有人知道這里發生了什么嗎？ 僅供參考，不要使用perlbrew之類的東西，我需要自己編譯:(。

事實證明，我需要將-Duse64bitall標志添加到Configure腳本。 所以最終我能夠與

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

對於我的設置，我還需要更多的庫，因此這是一個相當簡化的版本。 但是，它解決了本文中描述的問題。
