Yet another Raspberry Pi Lisa case, but this one has the STLs!

Hey Mark,
I pushed some new code last night to https://github.com/rayarachelian/lisaem.git (master branch) - there are still windowing bugs, but perhaps this has enough fixes to solve your issues on the Rpi.
Hope it helps.
Cheers,
--Ray

Hi Ray,
Do I need to compile the widgets again? If so, is there a way to copy (archive off) the version that works. Like thru SBM? I did use the Raspian SD card copy feature to copy the SD card, but I was wondering if there is a way to compile or work in "Development" as it were, while having a working LisaEm copy?
Thanks,
Mark

You only need to do that if something on the GTK side has changed - this will usually only happen when you upgrade the OS - but usually only on a major version, or if you haven't already compiled it with SDL and wish to enable sound.
Once you get a good known version of LisaEm that you're happy with, you can do
--- Code: ---sudo ./build.sh clean build install
--- End code ---
and that will then install it to /usr/local/bin/lisaem.
You can then do
--- Code: ---git pull; ./build.sh clean build
--- End code ---
to test updated versions, and if you like the changes and don't notice any issues, you can repeat the install. But note that
--- Code: ---sudo ./build.sh
--- End code ---
may change ownership of the object and binaries to root, so you may need to do something like
--- Code: ---sudo chown -R pi ./lisaem
--- End code ---
from the directory above it to fix it.
Also note that I'm close to doing another push to github in a few days, likely before Monday. Your patience might be rewarded, or not, depending on how many old bugs I fix vs new ones I intoduce. :-D

Hi Ray,
I'm back looking at this post and wanted to enable sound on the Raspberry Pi. Do I need to rebuild the GTK files again? I also wanted to know if there was a way to archive the work I've done (like I have it working), I did do a SD Card duplication which should be good backup, and you had mentioned doing an install clean build to my usr/local/bin/lisaem directory. I guess my question really is, how does UNIX work with builds, can you have different builds in different directories?
How do I tell my LisaEm version? (I found it in the About box = LisaEm 1.2.7-ALPHA_2019.11.11)
I wish I knew a bit more about UNIX, but this is a good time during COVID to learn a few things.
thanks for all your help.
Mark

Unfortunately so, it appears that for GTK, you should recompile wxWidgets 3.x --with-sdl and install the sdl libs and developer packages before you do so. I found a somewhat obscure note about this. Originally it worked just fine by adding the pulseaudio proxy, but not with 3.x. Meh.

Absolutely. You can backup any directory on linux using the tar command. There are other tools such as zip and rar and 7z, but tar is preferred. i.e.
--- Code: ---tar cpJvf archivename.tar.xz directory-to-backup
--- End code ---
To get a listing of what's inside the archive, you'd do:
--- Code: ---tar tJvf archivename.tar.xz | more
--- End code ---
And to restore, you'd simply do:
--- Code: ---tar xpJvf archivename.tar.xz
--- End code ---
The options to tar are c=create, t=table of contents (listing) x=extract, p=store permissions, v=verbose, J=use xz compression (note uppercase J here), f=next parameter is the name of the archive file. Instead of J you could use j=bzip2 compression - slower and lower ratio use the .bz2 extension, z=gzip compression - faster, but far lower compression, use the .gz extension.
To get more details about any unix command, use man. i.e.
--- Code: ---man tar
--- End code ---

If you've obtained it from github, the current version is a beta of 1.2.7. When you run
--- Code: ---./build.sh --help
--- End code ---
it will print the version in the banner.
