error opening quartus or compiling opencl files as This is happening with Quartus 19.1. Any env variable I am missing? quartus: error while loading shared libraries: libxerces-c-3.2.so: cannot open shared object file: No such file or directory

The right access of the libxerces-c-3.2.so delivered with Quartus 19.1 are wrong. To fix it:

chmod 555 $QUARTUS_ROOTDIR/linux64/libxerces-c-3.2.so

Same issue with libpython3.so:

chmod 555 $QUARTUS_ROOTDIR/linux64/libpython3.so

Same here, which distro are you using? Mine is: Red Hat Enterprise Linux Workstation release 7.4 (Maipo), which should be fully supported as far as I know...

I am using Ubuntu 16.04.

Download and install the following package and then try:

https://rpmfind.net/linux/rpm2html/search.php?query=libxerces-c-3.2.so()(64bit)

Make sure you choose the right package for the Distro.

Thank you,

I was for downloading the package when I realized that there isn't any package for my distro (Red Hat Enterprise Linux Workstation release 7.4).

I then tried to look inside Red Hat repository and found that only version 3.1.1-9 of the package is available...

Any suggestion?

Thank you

You can try the following:

cd ~/opt
wget http://apache.forsale.plus//xerces/c/3/sources/xerces-c-3.2.0.tar.gz
tar -xzvf xerces-c-3.2.0.tar.gz
mkdir -p xerces-c-3.2.0-build
cd xerces-c-3.2.0-build
cmake -DCMAKE_INSTALL_PREFIX=~/opt ../xerces-c-3.2.0
make
make install

Or just try installing the package for Fedora and see if it helps. This should not cause issues as this package is mostly used by Quartus alone.

fixed!

Thank you for your help!

Hi,

The message was "quartus: error while loading shared libraries: libxerces-c-3.2.so: cannot open shared object file: No such file or directory".

I think that you get this message when you install Quartus as root and try to launch Quartus 19.1 as a "simple user" which is not in the same group as root.

I'm using CentOS Linux release 7.6.1810 (Core).
