Re: [Pharo-dev] [Vm-dev] Removing most of the windowing code

by phil＠highoctane.be

Ronie, Is all of this in a branch somewhere so that I can have a look? For cairo, I think that I can build it with another compiler than MinGW, it doesn't really matter as it just makes a dll (or well, I can just skip that and reuse an already built one). -ltro is the flag that makes the whole thing trips up in GCC5 and requires additional flags, but adding them just kicked the can down the road a bit further as they were still unresolved symbols. Need to see why cairo build gives that but seems a cairo issue that others are facing as well. May end up building cairo with the old compiler but this defeats the purpose. For VS2015, I've got it too and yes, the debugging facilities are much better, not to mention that the compilation times are much nicer. GCC is just dog slow on Windows compared to Linux. I read that it was because of sub-bar fork support in Windows. Nice to give me an excuse to get an XBox One for XMas in order to try Pharo on it.

Re: [Pharo-dev] pillar latex and code listings

by Damien Pollet

EnterprisePharo is on master and there have been few LaTeX-level changes recently. The parent commit of master dates from april when we migrated a few books, and the recent commit was documentation. I think at a minimum you'll have to use a different latex exporter in the pillar.conf (check EnterprisePharo for that) to output the sbabook-specific environments and macros, but if there are problems beyond that it's a matter of how the main file and the templates are combined. At this point my recommendation would be to migrate to the makefile-centric build of EnterprisePharo.

I got working pharo,exe -headless Pharo-minimal.image eval "1+1" (the -headless parameter is for the image to quit after finishing). When running a normal Pharo.image, I am getting a FFI related crash (with Visual Studio and MinGW), when the image tries to read the APPDATA environment variable. Right now I am using the same main function for both, the Unix and Win32 VM. This means, that we are close of having the embedded version. In windows I am build two variants of the VM, pharo.exe (or squeak.exe) and pharow.exe (or squeakw.exe). The executable without the w is a console program, so it can use stdin, stdout and stderr. The executable with the w is a windows program that does not create a console window on startup, but it cannot use stdout, stderr, or stdin. This is the standard workaround for an annoying limitation of Windows itself (Python does the same in windows, with the same nomenclature). Visual Studio is unstable than MinGW, but it has an excellent debugger. With Visual Studio, I am getting some false positives for an assertion because they get miscompiled. For some reason, the assert(GIV(remapBufferCount) == 0) gets compiled into the same as assert(GIV(remapBufferCount)). Apart from this assertion, these two versions of the VM are crashing in the same place. > Fantastic, except: > > > - Unified standard CMake building scripts for Unixes. I hate autoconf.
