We are trying to compile OM 1.16.4 source code for Linux after compiling required dependencies

gcc (GCC) 8.3.0

lpsolve 5.5.2.5-r0
libexpat 2.2.6-r0
lapack 3.8.0-r0
lapack 3.8.0-r0

git clone https://github.com/OpenModelica/OpenModelica.git
cd OpenModelica
git submodule update --recursive --init
git checkout v1.16.4
cd OMCompiler
autoconf
./configure
make -j`nproc`

and this is the Output:

make: *** [Makefile:99: omc-bootstrapped] Error 2

And advice how to fix?

Hello,
We are comparing FMU's exported in OM 1.9 with OM 1.13.0-dev.593 (64bit), we see that new FMUs are at least twice slower than OM 1.9, I was wondering if anyone has reported similar issue, and if this is expected?
We can provide codes and FMUs if someone wants to look at them as a case study.

Hello there, I am facing the same issue exactly as you described (very well written by the way!),
Have you found an answer for this problem?
Thanks.
