Installing Pharo in Linux using the System Package Manager

One of the improvements that we are including in Pharo 9 is the update of the build process in OpenBuildService. This service allows us to produce packages for different distributions of Linux. These pacakges are built using the versions loaded in the distribution and they can be installed and updated using the tools present inContinue reading “Installing Pharo in Linux using the System Package Manager”

Running Pharo 9 in Docker

A Floating GCC Optimization

A couple of months ago, while debugging the build of the VM, I found a problem with the optimization of GCC 8.3 (I am not sure what other versions may show it). Basically, this GCC version does not compile one of our virtual machines functions well, because it unexpectedly removes what looks like valid code.Continue reading “A Floating GCC Optimization”
