When using a slowcontrol frontend which operates a device using the multi class
driver the current midas version (ec3225902d6) has the following issue:

Hi, we are part of the Mu3e research based at University of Bristol. We have a
remote 32 bit frontend (raspberry pi) connected to a 64 bit Data Acquisition
system.we are following the instructions at installation/quickstart linux/Build

Why don't your try the (yet undocumented) new installation procedure:
$ git clone https://bitbucket.com/tmidas/midas --recursive

Update: "make" instead of "make linux32" should also work. I believe the "linux32" target came
from some special case at TRIUMF for some FPGA embedded linux, which is not applicable for
the Raspberry Pi.

Yikes, the error is in the CRC library. The assembly-optimized crc32c function fails to build, and the
error does not look familiar to me. I do not see this error here. What is your host system ("uname -
a") and what is your gcc ("gcc -v")?

Thanks for your advice. We now have Midas installed on both our machines (remote machine-Rpi &
hostmachine-Centos).

If the latest midas does not work, try the previous release versions. "git tags" and "git branch -
a" will show you what exists. Look for branch and tag names in the form "midas-YYYY-MM".

Reproduced on el7 (CentOS7). Same thing works on el6 (SL6).
The error is in the SSE4.2-assembly-accelerated library for computing crc32c checksums. I do

Note that the example experiment compiles a simple example frontend and a root-based analyzer. If you don't have
ROOT installed, you of course cannot compile the analyzer. If you don't need the analyzer, remove it from the
Makefile/CMakeLists.txt

Fixed in commit dd937e6. Only enable SSE4.2 crc32c for 64-bit compilation. Still not sure why it worked for 32-bit
