The windows compiler certainly does support a 64 bit integer type (INT64 iirc). There is probably a configure check somewhere (the bundled mysql client library from 4.3 branch comes to mind) that you can use to make the decision on 64 bit support. --Wez. ----- Original Message ----- From: "l0t3k" To: Sent: Thursday, November 06, 2003 1:58 AM Subject: [PHP-DEV] Repost : 64 Bit Integer support > Question : > is there any one of the supported platforms that dont support a 64 bit > integer > type. i'm not referring to the native int size. > for one i can think of Windows 95/98. > > i'm porting a library and i need to know this so i can determine how to > proceed. --- ## #5282 — l0t3k — 2003-11-06T02:52:26+00:00 URL: https://externals.io/message/5276#5282 · In reply to: #5279 thanks, wez > There is probably a configure check somewhere (the bundled mysql client > library from 4.3 branch comes to mind) that you can use to make the decision > on 64 bit support. my concern is not the configure check, per se. im just concerned that having the extension depend on 64bit support would eliminate a significant supported platform. as i current only have access to MSVC and gcc, i wanted to do a quick shout to see if someone knew offhand which of the popular compilers would have an issue. l0t3k p.s.. its a largish codebase with 2 developers, so i wouldnt want to simultanously support a 64bit and a 32bit branch. > --Wez. --- ## #5307 — Michael Walter — 2003-11-06T22:47:43+00:00 URL: https://externals.io/message/5276#5307 · In reply to: #5282 Maybe something like that could help you: #define HAS_INT64_PRIMITIVE #ifdef MSVC #define int64_t __int64 #elif ... #else typedef struct int64_t_ { int32_t a, b; } int64_t; #undef HAS_INT64_PRIMITIVE #endif - Michael
