cmake bacongui-fltk

[bigbass]

Hello


I am testing cmake builds
they are working correctly

*however if you are a new bacon user
and stumbled here the official bacon package is here for your OS
www.basic-converter.org/


with that notice said here we go
with cmake builds


--------------------------------------------------------------------------
cmake building bacongui-fltk
sourceforge.net/p/bassix-gtk3-webkit-browser/wiki/Cmake-bacongui-fltk/

version gets updated on the wiki page
easier to maintain and less forum space needed
for downloads and images













HISTORY tech notes that may be useful to know

there were some difficult
problems to overcome to get fltk to compile
a lot of trial and error later the light came on and
I renamed the bacon source file from *bac.c to *bac.cxx
and then cmake could build it !

cmake can take c code and compile it with the c compiler
but if you want to use a c++ compiler (fltk code) we are forced to use
*.cxx or *.cpp type of file naming must be some built in
detection I couldn't override but found a fix for that

Dear Joe,

Thanks for that. I was able to run "setup" after modifying the cmake version info at the top of the CMakeLists.txt file (on my mint I need 10.2). Both the bacon and fltk version work.

With kind regards,
vovchik

Hello vovchik

Thanks for the feedback

that's a good point about the cmake version
will have to do something about that
I had to do the same on the RPI3 then thought it would be ok
so thanks for the heads up on mint

maybe I can add a cmake version test to the setup
and give a message tip if they don't match?



I added an uninstaller

TECH NOTES:
By default, CMake does not provide the "make uninstall" target, so you
cannot do this. We do not want "make uninstall" to remove useful files
from the system.


but they provide code to add that feature back in
gitlab.kitware.com/cmake/community/-/wikis/FAQ#can-i-do-make-uninstall-with-cmake

I added this fix to the build already

so it works correctly with cmake now

#sudo make uninstall

removed file to save space on the forum
CMAKE_BACONGUI_FLTK-4.3-007.tar.gz


we can bundle up some fltk apps now


thanks vovchik

Hello vovchik

I added a version get for cmake

# make a configure time system check for the cmake version
execute_process(COMMAND cmake --version
   WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
   RESULT_VARIABLE _RESULT )




and a range of versions it could use

cmake_minimum_required(VERSION 3.0.0...4.0.0 FATAL_ERROR)

but I don't know if it will work or not on mint but I think it should
I went to version 4.0.0 to play it safe for awhile
the latest is
Latest Release (3.19.2)

and 3.0.0 goes back to debian jessie on the low end


removed file to save space on the forum
CMAKE_BACONGUI_FLTK-4.3-008.tar.gz


if you get time please let me know if it
still complains about mismatched versions
thanks

Joe

Dear Joe,

Thanks. That did it. I just typed ./setup and it did what it was supposed to do.

With kind regards,

Hello vovchik

Thanks for the confirmation on mint!

I think it is a very good thing
the lexer has done away with
workarounds because of the $ symbol
and many more problems m4 couldn't
do cleanly (but could do )

all those benefits have produced cleaner code
and allowed for even cmake testing
another way to really test the source code

so as of today it is confirmed that bacon
and bacongui-fltk both passed the test
with a clean build

and we can package up any apps that are built
on bacon installing and uninstalling
and adds to bacon even more compiling options

none of this would be possible without
all the work Peter put into the constant perfecting of bacon

Hello
A minor but important fix

I added this then edited the bacongui-fltk to get it to compile
DATA_PATH$ = "/usr/share"

then when doing the gtk build I got the syntax correct
and now I am adding to the fltk build


# reduce binary size and strip
# FIX added DATA_PATH manually needed inside bacongui-fltk
add_compile_options( -DDATA_PATH=\"/usr/share\" -Wno-write-strings -Wno-pointer-arith -c -Os -s )

removed file to save space on the forum
CMAKE_BACONGUI_FLTK-4.3-009.tar.gz

Hello

these are the finals
I went back and made bacon the primary package
which will install the docs and syntax and icons

bacongui-gtk and bacongui-fltk
will only install the binaries and desktop files

this way you can safely uninstall bacongui-gtk or bacongui-fltk
and not have any missing files for bacon

all three packages now have debian package makers and rpm
if needed


I am happy we have cmake to install and build packages
and it was fun doing that for bacon and bacon apps

Hello


I am testing cmake builds
they are working correctly on the raspberry pi3

*however if you are a new bacon user
and stumbled here the official package is here
www.basic-converter.org/


with that notice said here we go
with cmake


just cd into the directory
then


cmake .





cmake --build .




if you want to install the binary
you can type


sudo make install




optional EXTRA features
let's say you have raspberry pi4
after the cmake --build .
you could generate a package using the command cpack
