Lazarus and web application

Good morning everyone, I created a small Git Hub project to
demonstrate how to create an application based on http application
that acts as a web server to manage the frontend part (kept external
to the executable itself), so as to be able to intervene on the
graphic part quickly , and integrates the backend so that it cannot be
modified by those who do not have the source.

Currently only tested on Win 10. I hope it helps someone.
The frontend of the example is based on AdmiLte a bootstrap template.
You can find more information on the blog of the Italian community
(the article is in Italian, but you can easily translate it with
Google Translator).

con-lazarus/

I then tried to cross compile it for arm/android but the compilation
fails because somewhere there is a reference to gtk3. If anyone could
help me cross compile it for Android I would be grateful.

Thank you very much for the example xiniman.

I just compiled your example (Linux) using the commandline compiler
and there is no sign whatsoever of such dependencies.

Code: Bash  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i cd
LazWebServer-mainfpc -FEbin -Fusrc -Fusrc/jwt_unit -dUseCThreads
-dSmartDebugLogWriteActive -B prj/lazwebserver.lpr 
I suspect it might be related to the android part of things. Are you
able to paste some log that is able to show what exactly the compiler
is looking for ?

I do not have a cross setup for android for this machine (sorry as I
have no intention to do so either (*)) so you might perhaps have more
luck with someone that is more versed in/with android.

(*) just discovered multipass   .

A perhaps possible solution for you:
- use FPCUpDeluxe to install (only) FPC 3.2.2 somewhere temporary
(e.g. do not mix with your current setup unless you really want to)
- Use FPCUpDeluxe to to add an arm android cross-compiler
- download and extract (or clone) your project source-files
- cd LazWebServer-main
- /full/path/to/your/temporary/installed/FPCUpDeluxe/directory/fpc/bin
/[x86_64-linux]/fpc.sh -FEbin -Fusrc -Fusrc/jwt_unit -dUseCThreads
-dSmartDebugLogWriteActive -Parm -Tandroid -B prj/lazwebserver.lpr

The [x86_64-linux] part is specific to my host so might be different
for you in case using another host OS.

Though I am not 100% sure about (your) ARM (target) options. Might be
that there is need to specify some additional details (depending on
your requirements).

this one just amazing.
(AdminLTE + Bootstrap + DataTable) serves management well.
