It <br>sounds right.<br>Although if you don't want to use the defaults, then I recommend to <br>*not* install Lazarus from apt, but simply download the git, create a <br>lazarus.cfg and "make clean all".<br><br><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> ...<br> If I use sudo apt install lazarus, will that also pull fpc as a dependency<br></blockquote><br>Yes.<br><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> or<br> should I use:<br> <br> sudo apt install fpc lazarus<br> <br> instead?<br> And what about the lazarus sources, are they pulled in as well with the sudo apt<br> install lazarus command?<br></blockquote><br>Yes.<br><br><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;">[...]<br> I have been building Fpc/Lazarus from sources since many years, also tested<br> fpcupdeluxe a few times. So getting/using the sources is known.<br> <br> I usually download the tarballs with a release tag from gitlab using wget.<br> After I have built fpc and symlinked into $HOME/bin I build Lazarus like this:<br> <br> cd $HOME/devtools/lazarus/2.2.6/<br> make clean PP=$HOME/bin/ppcarm && make bigide PP=$HOME/bin/ppcarm<br></blockquote><br>Shorter:<br>make clean bigide PP=$HOME/bin/ppcarm<br><br><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;">[...] > New fpc?<br> Being able to upgrade fpc on the side without disruption of Lazarus is also an<br> issue for me, is there some setting/config within the pcp directory that I can<br> change to point Lazarus to a new fpc compiler and it will then be possible to<br> rebuild Lazarus with that new compiler?<br></blockquote><br>For compiling your project set the compiler in Project Options. Use <br>build modes for multiple platforms.<br>For compiling the IDE with different fpc versions, install the fpc <br>sources in paths that only differ in version number, so you can use the <br>IDE macro $(FPCVer). Then you can easily switch the used fpc in Tools / <br>Options / Env / Files.<br><br><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> And what about day-to-day project compiles if I want to use the new compiler?<br> Is it as simple as changing the symlink of $HOME/bin/ppcarm to point to the new<br> compiler? It would affect all user installs utilizing the ppcarm compiler.<br></blockquote><br>Using build modes sounds easier.<br><br>Mattias</pre></blockquote></div></body></html>
