Re: [fpc-pascal] Smart Link definition ?

Sorry, for the question, but is it really working for FPC+Lazarus? I mean FPC with smart-linking from trunk. Last time I tried, I could not complete full FPC and Lazarus rebuild. BR, Denis 10.10.2016, 18:03, "Jonas Maebe" : > On 10/10/16 16:25, fredvs wrote: >>  Does somebody know if smart-link

Re: [fpc-pascal] [PATCH] Addition of OnNotify event on "TFPGObjectList" and "TFPGList" triggered on the insert, delete and extract methods.

Hi That always keeps me wondering - why neither FPC, no any other mainstream static-type language implements specialization based not only on types, but on compile-time constants as well? I mean something like   TGenericList = class    ...  end; procedure TGenericList.Delete(index:integer);begin  i

[fpc-pascal] Lazarus smartlinking

Hi all I am trying to get smartlinking working, but it seems a bit harder than I expected. I am interested in both Linux and Windows arches. I was able to build fpc using "RELEASE=1 CREATESMART=1 LINKSMART=1" make flags. So far so good. However, when I tried building Lazarus with the same make f

[fpc-pascal] fgl.TFPGMap / operator not overloaded for object types

Hi all I am wondering if somebody created a bug request for the problem described in http://lists.freepascal.org/fpc-pascal/2011-January/028020.html ? If not I'd like report it :) I am asking because I stumbled across the same issue under fpc 3.1.1 (rev.30041) -- Regards, Denis Golovan

Re: [fpc-pascal] Linux x64 linking error (FPC_ABSMASK_SINGLE)

> How can I fix it? Should I pass -fPIC argument (and how to do this)? AFAIK, PIC code generation is turn on by default. Are you sure you don't have an opposite problem? Sometimes when you have asm code written with hard-coded offsets you can get a module which can't be PIC-compiled. See fpc -h

[fpc-pascal] Heap manager tuning

Hi all I am trying to debug an issue that seems to be related to FPC heap manager. Test machine - Linux x64. It looks like really large memory "overhead" compared to cmem manager. Test load profile - 50 heavy objects with around 25 large (1Mb - 10Mb) dynamic arrays each. Those arrays are created
