Cannot recompile lazarus-2.0.0 on RPi 3
lazarus / 1-Linux

----------------------------------------------------------------------

I have need to install a visual component in Lazarus on my RPi 3.  (I
won't be doing development on the Pi, just compiling from source using
lazbuild.)  When I install the component, however, and attempt to
recompile the IDE, I get 'cannot find fpdebug'.  I have followed
instructions elsewhere to increase the size of my swapfile, to 2048
megabytes in fact, and I still get the error message.  Can anybody
please help?

Tried using lazbuild --build-ide= to rebuild the IDE (thinking that
this uses less RAM than the full IDE) and got the following output:

If you do not use FpDebug, then you can uninstall it. By default it is
installed as a dependency for package LazDebuggerFpLldb (for Mac
users).

If you installed packages of your own, any package that contains Debug
and Fp, like LazDebuggerFp or LazDebuggerFpGdbmi.
The default gdb debugger does not need FpDebug.


I read on another thread on the forum, someone claimed, they had to do
"make" in the component folder first. I do not recall which thread it
was....

For the rest, someone with knowledge of the Makefiles need to answer
this.
