cannot install Lazarus deb
lazarus / 1-Linux

So, https://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20a
md64%20DEB/Lazarus%202.0.12/
has an old FPC that won't work with the very same Lazarus version it
is sitting next to. Lazarus deb complains that it can't find fpc >=
3.2.2 and the sourceforge has fpc-laz_3.2.0-1_amd64.deb
which is too old.

no problem, i build fpc from install.sh and it is in
/usr/local/lib/fpc but i also symlink to /usr/lib/fpc
(the installer asked if i wanted /usr/local or just /usr)

lazarus-project_2.2.0RC1-0_amd64.deb does not see it and refuses to
install...

building from source from handy git repo mirror with handy build
scripts works OK:  https://github.com/alrieckert/lazarus

I will see where in Lazarus i must configure fpc paths and will be ok.

just mentioning that current fpc version next to lazarus installer on
sourceforge is incorrect for the lazarus ide sitting next to it with
instructions that you need all files, but files are wrong.

Generally speaking I install FPC from the freepascal.org release and
then build Lazarus from source and find it painless.

Installing Lazarus from source is easy, reliable and is generally a
better model IMHO.

ok, thank you for the link and information.

because of initial problem building:
/usr/bin/ld: cannot find -lgdk-x11-2.0
/usr/bin/ld: cannot find -lgtk-x11-2.0

I thought to add two more "linux dependencies" for the wiki:

libgdk2.0-dev
libgdk-pixbuf2.0-dev

(I have ubuntu 20.04)

should I make a wiki account to do this? MarkMLI

Hmm, they should be, themseleves, dependencies of libgtk2.0-dev - did
you install libgtk2.0-dev ?  Or did I send you a link too far down the
page ??

I agree, that's the important one for Lazarus (built for gtk v2, which
is still the safest default). I've got notes that show that those two
were required separately for GTK v1, so reading older material and
extrapolating could potentially cause confusion :-)

For FPC something like libncurses5-dev, libncursesw5-dev and possibly
libgpm-dev are needed.

There's other stuff worth adding as well: development packages for USB
and database access etc. But these are definitely not mandatory.

yes, we try and have just whats needed mentioned on the wiki. If you
wish to use other libraries in your particular app, then you should
understand you need to dev libraries for that too.  For example, I use
libnotify so I need libnotify-dev.

af0815, your list does puzzle me a bit, are these things that need to
be added to the wiki ?

* libgtk2.0-dev - is mentioned on the wiki.
* libgtk1.2-dev - GTK 1 ?
* libgdk-pixbuf-dev - is a dependency of libgtk2.0-dev
* libgpmg1-dev - do you mean libgpm-dev ? 
* fakeroot - only if building, eg, deb packages
* libncurses5-dev - not needed for Lazarus apps.
