[plexil-support] Installing PLEXIL on Raspberry Pi 4

[Erich G. <eri...@gm...>]

Hello,
I've been trying to install PLEXIL onto a new Raspberry Pi 4 model with 8gb
ram, running the lastest Ubuntu, and I've run into an issue that I've been
beating my head against for the past couple of days.

The issue in question is here:
make[5]: Entering directory '/home/user/plexil/src/third-party/ipc/src'
gcc -Wall -Wstrict-prototypes -Wnested-externs -Wmissing-prototypes
-Wmissing-declarations -O2    -fPIC -I. -I/home/user/plexil/include
-DREDHAT_52 -DREDHAT_6 -DREDHAT_71 -DTHREADED  -c -fpic -o
/home/user/plexil/src/third-party/ipc/sharedObj/Linux-6.2/datamsg.o
datamsg.c
datamsg.c: In function ‘x_ipc_dataMsgCreate’:
datamsg.c:1162:40: error: ‘IPC_ALIGN’ undeclared (first use in this
function)
 1162 |   dataMsg->alignment = (ALIGNMENT_TYPE)IPC_ALIGN;

I believe it has something to do with the compiler not linking files
appropriately, but I do not know how to solve this issue. I've installed
every library that I can think of. At this point. Has this issue ever come
up in the past, and if so, how was it solved?

Thank you for reading this,
Erich Geisert
