Hello,

With an up-to-date Git clone folder, when I try to make PLATFORM=simulator on GNU/Linux, I see this warning. But epsilon.elf seems to work fine.

good morning. I'm a new user of numworks. yesterday I installed the SDK system with mysis, but I have problems starting the computer simulator. when I try to give the command "make PLATFORM = simulator", the simulator does not start. I followed the Numworks site guide, but I have some doubts. in which folder do you need to be before executing "export PATH = / mingw64 / bin: $ PATH"? maybe I did something wrong with the installation. HELP me please. Thank you very much for the attention. good day

The make PLATFORM=simulator (warning, no spaces, here and in the other commands you mentioned) does not launch it, it only builds it. You then need to run the created executable file.

Fgdesmo commented 6 years ago

ok. thank you. I did not explain correctly. it does not create the "epsilon.elf" file. it gives me an error. tonight, as soon as I finish working I try to send a screen shoot. Thank so much

Good evening, here is the error that comes when I try to create the EPSILON simulator: $ make PLATFORM=simulator HOSTCC kandinsky/fonts/rasterizer /bin/sh: pkg-config: comando non trovato /bin/sh: pkg-config: comando non trovato /bin/sh: gcc: comando non trovato make: *** [kandinsky/Makefile:57: kandinsky/fonts/rasterizer] Error 127

I have no idea what may cause this problem. I do not know the Linux environment, because I've always worked in Windows. Could it be a configuration problem? where can I find information on using the simulator, its configuration and how to edit files? I'm a fan of electronics and I enjoy building with microcontrollers, but in this environment I'm really in trouble .. I'm waiting for help. Thank you very much for the attention. Good night John PS: I apologize for my English from "google translator" ... ;-)

I apologize. I tried to reinstall the different packages and I get the following error when I try to create the EPSILON simulator: $ make PLATFORM=simulator I18N apps/i18n.cpp HOSTCC escher/image/inliner HOSTCC kandinsky/fonts/rasterizer /bin/sh: pkg-config: comando non trovato /bin/sh: pkg-config: comando non trovato kandinsky/fonts/rasterizer.c:15:10: fatal error: ft2build.h: No such file or directory

compilation terminated. make: *** [kandinsky/Makefile:57: kandinsky/fonts/rasterizer] Error 1 I do not know what to do...

adriweb commented 6 years ago

Very much the same thing as multiple issues here on GitHub, just install the pkg-config package.

Fgdesmo commented 6 years ago

ok. thanks a lot. tonight I try to download the configuration file and let you know. to download pkg-config I have to write" pacman -S pkg-config "?

adriweb commented 6 years ago

Almost, see here: https://github.com/numworks/epsilon/issues/549#issuecomment-395495383 or here: https://github.com/numworks/epsilon/issues/554#issuecomment-395968333 You can close the issue afterwards.

Fgdesmo commented 6 years ago

perfect!!!!!!!!! now he created the "epsilon.exe" simulator. I thank you very much for your help. now I try to do some experiment ... One last question, could you explain to me where I can find instructions for reprogramming and to modify the calculator's applications? is there a manual or should I look for information here on github? thanks again and goodnight!

ljoets commented 6 years ago

Sorry, but what does that have to do with the first post ?

adriweb commented 6 years ago

Maybe he assumed build warning ~ build error...

Fixed in pull request https://github.com/numworks/epsilon/pull/628. Sorry, I should have seen this post earlier.

But since, similar error do still exist :

escher/image/inliner.c:178:5: pixelBuffer should be cast in char*
apps/shared/storage_cartesian_function.cpp:69:28: numberOfChars is of type int and compared to bufferSize which is of type size_t. Actually, numberOfChars should be of type size_t but that needs to change integer types into size_t (which should be ok because they shoul be never negative) in some prototypes such as nameWithArgument, and some constants such as k_maxBufferSize.
apps/shared/text_field_with_extension.cpp:25:48: probably linked to the precedent item

I compiled the simulator in Raspbian Buster Linux on Raspberry Pi 4 B and get many warnings, but the simulator seems to work.
