Portable verion of FPC and Lazarus

[LeP]

Compilers create enourmous impact on SSD, less than cache of browsers (which can be totally avoided/disabled), but still we have enormous transfer rate, thus lifespan of SSD will be quite fast reached.

@backprop
Then have fpcupdeluxe for install and have configure compiler output result to virtual memory.

In Delphi I use a ram disk. All my projects compile on ram disk all temp things, like dcu, maps, debug. Simple and reliable.
Of course in Windows.

Delphi is quite different... It doesn't recompile RTL nor components when some compiler directives where changed. Long time ago was talking about making and using components dynamically as in Delphi, but that never accomplished and it will never hapens...

With need of multiple FPC/Lazarus versions, at least two, last "official" release and one from trunk it is clear why transfer rate with SSD is quite enormous...

Can make same for freepascal/lazarus for windows/linux (not know for mac) and also use ramdisk (is same virtual memory) if want.

is also hint for backprop, it no matter what do delphi and what do freepascal/lazarus: make output for store at virtual memory.

This solves practically nothing if all need to be recompiled all over all the time and set all over again on every project and Lazarus itself. Long time ago, when memory and speed was limited and precious, all needed to be optimized, even compiled files, now, another approach need to be done in order to avoid SSD destruction. Why not focus on that?

Would it be possible to rebuild entire Layarus in memory and how much will be last full process? Well, that is not solution in this case.

That is why exist special filesystem that is SSD optimize.

Yes, /and/ run lazarus complete in memory if want but I not know what is "how much be last full process".

For instance? I'm not aware of any, except to use live distro. Every distro, every application I'm aware saves quite a bit data withouth single reason, not only caches which can be relocated or disable in some way. Even with large  buffer and algorithm to distribute data blocks inside SSDs, phycial limitation of FETs can't be avoided. Others prefer to buy cheap SSDs on ever few months and do not care much even on agresivelly writing browser cache... On everything is need to take care to minimize transfer rate on SSD.

I do that already for my own small projects, but since IDE need to be recompiled from time to time and even on changing project model and some directives all seems quite messy and unpredictable...

It doesn't really matters if you do not care for SSD lifespan...

Are you talking flash drives or cards or SSDs? I still have all my SSDs(close to ten in total), including the early 2008 one in my Core2 6600 that survived doing FPC development for half a decade.

By "cards" you meant nvme? Well, all use basically the same technology and NAND chips. And all FETs (one bit cells) become damages slighty during erased/writing cycle. It is all in specification of is. Cheap one have very short lifespan, maybe just few 1000s, some quality ones even 30 or 50 000 cycles... You can't generalize in form "I never had any problems with" if you do not know exactly manufacturers specification. I use one some 4 years and still have 90% lifespan left with perfect SMART status. But some my collegue bough the same model when I did and he ruin it in 3 months complaining it is garbage... But he didn't take any precaution measures to minimize transfer, even he use it for OS only...

UBIFS, JFFS, F2FS etc.

You make confuse write  You want use or not want use SSD ?

if want SSD then SSD have limit (platter HDD have also limit but have more better limit when not throw/vibrate).

Then exist filesystem that have know flash memory and store data and use special method for this.

You write not want and only solution is live distro. I make suggest write output to memory and then you have write this not work ok (it do).

Then is also exist frugal install and is other solution for not write live physical device (read only).

I do that already for my own small projects, but since IDE need to be recompiled from time to time and even on changing project model and some directives all seems quite messy and unpredictable...

May be I not have understand correct what is mean messy...

It work same as write SSD/HD only differ is all byte is store in side memory.


And may be I not have understand correct what is mean unpredictable...

Process for build (fpc and lazarus) all make same result every time (ok, location is can differ).


I have run linux SSD and use simple ext4 for many years. I make all build output to memory and only make install SSD when want have for keep.

Example cache browser you write is for me configure and store memory.

I have think is many misunderstand what is make wear SSD and how can make measure for prevent. There is exist SSD and have error controller firmware or have bad SSD (or have fake replicate). It is happen some time.

I not write you have no valid concern but there is exist solution for have more better care for SSD if want.

A lot of effort is currently being made to achieve just that. Better follow the development a bit closer. Not Lazarus, but the compiler.
It is not by any means ready yet, but PascalDragon, who leads that development,  has only so much time and the time available for FPC is for a great deal spend on just that: Dynamic packages.
Once that is in place, the recompile cycle for Lazarus becomes obsolete.
Note that that only bothers me on my last Raspberry Pi 1 that still works. Recompile is quick even on modest hardware.

If you do not understand, then stop replying, simple as that. I was perfectly clear what I refer to and from whom I expect clarification. And didn't I wrote that I do not want messy Ai replies? This is exactly what is happening here!

No SD cards. I did rot quite a few in my older RPIs over time. Which is why I in the end attached an old sata SSD via an USB->Sata converter to it. I compile on the SSD, not on the SD.

Yes, but different kinds quality and  overprovisioning.

I have OS and the compile business on it, and work 40 hrs a week ( plus maybe another hobby) on it. Several SSDs, the current one (my first NMVE TLC though) holding up fine for 6+ years already. Several at work, but those get stressed less.
