2010年1月27日 · 80386/i386 was the first 32-bit Intel processor. When it was introduced, lot of compilers started using i386 as a flag to turn code-generation for it, a name for various temporary files, and architecture denominations in file names. 80386 was succeeded by 486, 586 (aka Pentium) and the rest of the x86 architecture CPUs.

2014年3月22日 · i386 refers to the 32-bit edition and amd64 (or x86_64) refers to the 64-bit edition for Intel and AMD processors. Wikipedia's i386 entry: The Intel 80386, also known as the i386, or just 386, was a 32-bit microprocessor introduced by Intel in 1985... This is termed x86, IA-32, or the i386-architecture, depending on context. Wikipedia's x86_64 ...

2009年11月23日 · i386 is for 32 bit processors. All Core 2 Duos are capable of running 64 bit operating systems and 32 bit operating systems. You want x86_64 as it will run better and allow you to have more RAM in the future, although if you are worried about compatibility, you could use i386. Personally I haven't had any problems with x86_64 on Linux.

2016年4月1日 · a.o: file format elf32-x86-64 architecture: i386:x64-32, flags 0x00000011: HAS_RELOC, HAS_SYMS start address 0x00000000 Does it mean the library is 32-bit? Is that the reason I am getting the linker error?

2010年2月1日 · i386 is for extremely old CPU generation dating before Pentium. i686 is post Pentium generation. No one today have i386, they are at least 15 years old. That being said, i386 marks a 'compatibility' build and should work on ANY 32bit x86 CPU. i686 may or may not use MMX, SSE and more extensions.

What is the most reliable way to find out CPU architecture when compiling C or C++ code? As far as I can tell, different compilers have their own set of non-standard preprocessor definitions (_M_X86 in MSVS, __i386__, __arm__ in GCC, etc). Is there a standard way to detect the architecture I'm building for?

2014年1月30日 · i386 is the name of the 32-bit instruction set first implemented by Intel in the 386 processor. It became dominant thanks to dirt-cheap PC hardware. x86-64 is the name of the AMD extension added to i386 to make it capable of executing 64-bit code. This is the one you have.

2021年11月17日 · Ubuntu produced i386 ISOs into the disco (19.04) cycle which was well past artful or 17.10; it's just that fewer ISO options were provided; eg. Ubuntu 18.04 LTS ISOs were produced (including flavors ), just no desktop ISO, but you could use another ISO & add the desktop as Ubuntu Desktop was fully supported in 18.04; just no i386 Desktop ISO ...

/usr/bin/ld: i386 architecture of input file `*external-32bit-lib*' is incompatible with i386:x86-64 output From what I gather, I should therefore use: set (CMAKE_CXX_FLAGS "-m32") This does change things - I now get several errors like: /usr/bin/ld: i386 architecture of input file `*project-output-lib*' is incompatible with i386:x86-64 output

So, how to install i386 package on amd64 under the ubuntu/debian multiarch environment? This is the follow-up for Why I can't see Ubuntu restricted packages, where the sl-modem-daemon package doesn't have the amd64 but only i386 version in Ubuntu.
