Missing libraries even when libgfortran.x86_64 is installed #67

Open esaliya opened 9 years ago

Hi,

I was trying to do the following,

java -server -jar jblas-1.2.4.jar

and I get the following error. I've already installed libgfortran.x86_64 using yum. Any thoughts?

-- org.jblas INFO jblas version is 1.2.4 Simple benchmark for jblas

Running sanity benchmarks.

On Linux 64bit, you need additional support libraries. You need to install libgfortran3.

For example for debian or Ubuntu, type "sudo apt-get install libgfortran3"

Hi,

I have gotten this running for redhat/centos, but don't remember the exact packages right now, sorry. Maybe the development variants?

Hi,

I ran into the same issue on centos and I got it working by specifying this jvm option: -Djava.io.tmpdir=/path/to/another/tmp/dir

mikiobraun commented 4 years ago

Sorry for the late reply.

Odd that tmpdir changes fixed it, maybe the original place wasn't writeable? Let me look into this... .

digulla commented 2 years ago

I suspect a security feature: Loading of .so from /tmp is disabled (because attackers can easily put arbitrary stuff into /tmp).

This advice fixed the issue for me in RHEL8: Create a tmp folder for your app and point the Java VM to it using -Djava.io.tmpdir=...
