I share your sentiment about LinkedIn and MicroSoft. 😁

Work in progress / Update on ϕEngine
Last post by PabloMack - July 22, 2026, 08:37:34 PMI just read my post of April 16, 2020. Since then I have made many modifications and now the architecture defines both a 32-bit sub-architecture (called ϕEng32) with 32-bit address spaces and a 64-bit sub-architecture (called ϕEng64) with 64-bit address spaces. The two sub-architectures share the same instruction set. The reason why ϕEngine is able to do that when most others can't (including x86, ARM and RISC-V) is because all address computations are done in special Address Registers and not integer registers. That frees the integer registers to support all types and sizes for both sub-architectures. ϕEngine is more orthogonal than x86 in that you can directly use all sub-parts of all registers as registers themselves. x86 can only do this to a very limited extent such as al and ah being the lower and upper halves of ax. But you can't use R8~R15 that way. And you can't even directly reach the 3rd or 4th order bytes in eax or even the upper half of eax as a 16-bit register. But you have direct access to all of them in ϕEngine. Not only that, you can reach all registers as 1, 2, 3, 4, 5, 6, 7 or 8-byte integers directly. One thing that makes ϕEngine far easier to program is that data size extension it built into the loads and stores so you don't need separate conversion instructions. They are built into the basic operations.
The focus of ϕEngine has changed from performance to memory efficiency for both code and data. ϕEngine processors consistently have denser code and need less memory to perform the same functions as other processors. All of the SW tools are written in C. I have once again begun to port code from WATCOM to Pelles. I waited a long time for WATCOM to support AMD64 and have decided that Pelles is the way to go.
I just finished rewriting a function I use a lot in the tool chain to zero-extend any integer to one of a larger size. After writing it in Pelles C assembly I wanted to see how much easier it was to write in ϕEngine assembly and compare the code densities. The AMD64 version is 43 bytes and the ϕEngine version did it in 27 bytes.
I assembled the x64 version to produce an assembly listing. It has a lot of space in it to make the columns aligned. I saved this same file into the ϕText format that I use for storing all ϕ System documentation and source code. The Pelles C listing takes up 3053 bytes while the ϕText encoded file occupies 1361 bytes. That is less that 45% the storage requirements.

Last post by Vortex - July 22, 2026, 03:27:16 PMTimo is right. For example, Pelles C can be installed on the root partition, C:\PellesC

Last post by TimoVJL - July 22, 2026, 11:33:12 AMAdd-Ins are useless, if they need certificates.
Better to install Pelles C outside Windows Program files folder for a good reason.

Last post by John Z - July 22, 2026, 07:46:46 AMHi Robert,
No, this is unrelated to Pablo's resolved issue.
These two dll's are not needed for Pelles C. They are add-in programs, so the fact that they have been blocked just removes the Add-in. No Pelles C functions are affected.
It is interesting that they were blocked though as I've done a new install without issue. Perhaps you've set security higher. There is a setting as I recall for unsigned program blockage or something like that perhaps unknown ... Could be Internet properties or windows, I'll see if I can find it.
For most open source or free programs like Pelles C, it is costly to provide signing. Meanwhile Pelles C will be fine.

Update: Under Windows Security, App & Browser control, it is probably Smart App Control.
Image attached if on try with OFF if you'd like to.... if that does not do it check out the other two categories on the same page

Last post by Robert - July 22, 2026, 05:07:20 AMI just did a fresh install of 14.5 on a fresh install of Windows 11 25H2 to Pelles default install folder.
When I started the IDE, notifications from Windows Security popped up. Please see attached images for details.
The IDE opened, as usual, with the Build Libraries prompt.
Perhaps this is related to the problem PabloMack is having.

John Z
Also if you cd to PellesC bin directory and type poide does it run?
If you do this it will run. I can duplicate what you are seeing. Just use poide.exe and it will run after you execute one of the povars batch file.
I got the same 'error' when just using poide outside of the bin directory.

Another option is to just rename poide.com to no_poide.com - then using poide at the top level of C drive also works. Two options -
