CopperSpice Experiments – Pt. 4

Keep in mind I have a minimal Ubuntu 20.04 LTS on this system and will be building PostgreSQL support into CopperSpice. The Building for Unix instructions assume a full installation and even then aren’t complete. By using a minimal install I can help even non-Ubuntu users because I will find everything that got missed.

sudo apt-get install libfreetype6-dev libfontconfig1-dev libglib2.0-dev libgstreamer1.0-dev \
                libgstreamer-plugins-base1.0-dev libice-dev libaudio-dev libgl1-mesa-dev libc6-dev \
                libsm-dev libxcursor-dev libxext-dev libxfixes-dev libxi-dev libxinerama-dev \
                libxrandr-dev libxrender-dev libxkbcommon-dev libxkbcommon-x11-dev libx11-dev

sudo apt-get install libxcb1-dev libx11-xcb-dev libxcb-icccm4-dev libxcb-image0-dev libxcb-keysyms1-dev \
                libxcb-render0-dev libxcb-render-util0-dev libxcb-randr0-dev libxcb-shape0-dev \
                libxcb-shm0-dev libxcb-sync-dev libxcb-xfixes0-dev libxcb-xinerama0-dev libxcb-xkb-dev cmake ninja-build libxcb-glx0-dev

One of the first things I want to do is try converting my XpnsQt project from Qt to CopperSpice. This and my lottery tracking application are my goto tire kicking applications. XpnsQt needs PostgreSQL.

I rebooted at this point so all would be good with PostgreSQL.

Yeah, the import works from the oldest year it finds a data file for to the current year. I just don’t have files for this year on this machine. Data from 1996 or so through 2019 should be more than enough to kick the tires.

My first attempt at configuring CopperSpice failed rather spectacularly.

I was rather shocked to see Cups, Alsa, SSL, and PulseAudio in the list of things that weren’t there. The Alsa and PulseAudio were listed in the table on the documentation link, just not in the commands.

This time should work, right?

Since I know I installed the official libraries, this is a bit of a head scratcher. Scrolling back in the output I see the following:

I won’t bore you with how many times I edited my .profile assigning different values to PostgreSQL_ROOT and PostgreSQL_TYPE_INCLUDE_DIR. I even started rebooting instead of just logging out and back in. I will share an image of one of the stupid things a person tries when the doc leads them off a cliff.

Ah! /usr/include/pqxx/types Now there is excitement! Nah. False high.

That’s the package you need. The number will change with PostgreSQL version, but you need postgresql-server-dev-nnnn. It installs a standard U.S. buttload of dependencies when you select it.

Yes, I rebooted after this to see if things would work. This time when I entered the command:

cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/lib/cs_lib ~/Projects/copperspice

I had much greater success.

Like most of the known universe, I quit caring about MySQL when Oracle bought InnoDB. Someday Oracle will squeeze that orange for every drop of juice and I don’t want to be relying on it.

Now we can build CopperSpice.

I believe I also had to manually install CMake.

The screenshot utility that comes installed with Ubuntu 20.04 LTS blows

On KDE Neon they have a great one. You can tell it to delay when you are going to scrape a screen section so you can navigate to the proper place in a menu system. Not on this one. They have a delay, but it is only for entire windows or screens.

Adding insult to injury it will randomly show you a screen shot an then save a garbage file after you give it a name. I can’t find a pattern, it just does it. There are half a dozen screen scrapes that didn’t get into this post series already because it “said it saved them” but the file was trash.

The other insulting feature is that it autosnaps as soon as you get done dragging the mouse. The default one on KDE Neon leaves the box around what you selected and allows you to adjust things before hitting return to select your scrape. When the left margins are hosed in this post series, that is why.

One thought on “CopperSpice Experiments – Pt. 4

  1. I saw your post on the Copperspice Forum and decide to check it out.

    Should be an interesting review. I write software using Qt both Commercial & Open Source, on Windows and Linux, using any number of compilers.

    My work with Copperspice has been limited due to compiler constraints…. for 3’rd party packages I have to use older compilers. But I have just installed MSVS 2019 so giving that a whirl.

    I looked forward to future discussions.
