As per Vincent's request, the discussion has been moved from the bug
tracker to the mailing list.
I will list my vague recollection of the ideas I had for brain storming
purposes, as I used to cross-compile a lot (it has been some time since
I haven't!), and switch different FPC versions. I thus devised a script
that help me switch easily:
# Disable Ubuntu's overlay scroll bars which do not work with Lazarus
# Specify FPC version
# Add to the path the 3 required paths for the full operation of FPC and
binutils for cross compilation
The downside is:
1- Having one script per FPC version
2- The FPC executable and sources path must be changed in the IDE options.
3- Rebuilding Lazarus from within does not relaunch the IDE automatically.
Selecting the proper fpc version in the environment options the way it
is now is difficult as 2 paths have to be edited and changed (once for
the fpc executable and another for the fpc sources).
I am not sure about manually creating symlinks from
/home/me/Programs/fpc/2.6.1/lib/fpc/2.5.1/ppc386, as this should be done
by the FPC install itself if ever. Furthermore, this does not resolve
how Lazarus will select the correct fpc executable among the different
versions. I say leave fpc itself locate the actual compiler.
My proposal is:
- Add to the IDE's option a dropdown list where one can add versions and
select the required one which will be used as an FPC_VER macro.
- Allow the export of environment variables such as the PATH in the
This will not solve downside #3, as a script is still needed for the
--pcp option and the overlay scrollbars issue, but it will make
switching FPC versions a breeze.
