hi, to compile a chess engine (Booot v6.5) i downloaded a set .pas files (with .dpr and .dproj file) but i'm not able to compile it on Linux (Xubuntu 22.04) .. i have FPC v3.2.2 installed and even Lazarus, but i'm stuck .. in terminal i tried :

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---$ fpc ./booot6.dprFree Pascal Compiler version 3.2.2+dfsg-9ubuntu1 [2022/04/11] for x86_64Copyright (c) 1993-2021 by Florian Klaempfl and othersTarget OS: Linux for x86-64Compiling ./booot6.dprCompiling uBitBoards.pasCompiling uMagic.pasuMagic.pas(91,6) Error: Identifier not found "Result"uMagic.pas(113,5) Error: Identifier not found "Result"uMagic.pas(135,5) Error: Identifier not found "Result"uMagic.pas(147,5) Error: Identifier not found "Result"uMagic.pas(157,5) Error: Identifier not found "Result"uMagic.pas(171,4) Error: Identifier not found "result"uMagic.pas(177,5) Error: Identifier not found "result"uMagic.pas(182,5) Error: Identifier not found "result"uMagic.pas(212,4) Error: Identifier not found "Result"uMagic.pas(347,11) Error: Identifier not found "Result"uMagic.pas(362,4) Error: Identifier not found "Result"uMagic.pas(421) Fatal: There were 11 errors compiling module, stoppingFatal: Compilation abortedError: /usr/bin/ppcx64 returned an error exitcode
the package does not have any README file .. do i need to add some parameters / options ?
i'm not a beginner at Linux, but i never did any Pascal.
i guess compiling my source should be pretty simple .. can anybody help me out ?

Hello.

Try to compile after adding this at begin of unit ( after: unit uMagic; )

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---{$mode delphi} {$h+}
[EDIT] You may also use the mode parameter for fpc:

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---$ fpc -Mdelphi ./booot6.dpr
[EDIT2] You may also try the excellent "pure fpc" chess engine from Roland:

indeed, the first line of 'uMagic.pas' is 'unit uMagic;' so i added '{$mode delphi} {$h+}' on the next line, as you suggest, but now i get this error :

your second option didn't succeed either :

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---$ fpc --Mdelphi ./booot6.dprError: Illegal parameter: --MdelphiError: /usr/bin/ppcx64 returned an error exitcode
it failed .. i guess your '--' should be '-' so i did this, but it also failed :

Fred vS:
Hum, difficult to give a diagnostic without seeing the source... :-[

Maybe in uHash.pas, in uses section, remove Ansistrings unit.

Ooops, yes, fixed in previous post.

tissatussa:
i can put a ZIP with the source here.

your newest option (compile the Moustique chess engine) DID succeed according to the compilation line on that page : i get a working binary.
