2026-03-30Cmake status information outputAlexey Gavrilov2-0/+2
Reinforce of compiler, C runtime, architecture checks at cmake configuration. Compiler check means continue building at the cmake configure stage only for supported compilers. Use unsupported compiler involves immediate build process stopping. C runtime check means finding of runtime objects. Especially for *crtbegin.o* and *crtend.o* files. Architecture means *ObjectiveProject_ARCHITECTURE* variable is set. That variable configure at toolchain file by default and cannot override if toolchain file is passed.

2026-03-28Cmake build type at the generation stageAlexey Gavrilov2-4/+0
Fix in *nasm* files - set architecture bitness. Move compiler flags from *toolchain* file to *requirements target* considering cmake files. This solution allows available of multi-configurations generators to pass compiler options without affecting on single-configuration generators.

2026-03-28Cmake build generator support: toolchain fileAlexey Gavrilov2-0/+20
Two toolchain files for clang and gcc compilers under x86 platform. Debug flags also passed at the configure time. Signed-off-by: Alexey Gavrilov <alexey.gavrilov@mail.com>
2026-03-27Cmake build generator support: build stageAlexey Gavrilov1-0/+8
Multi-target architecture implementation: each root source code directory presents the one *INTERFACE* target to it's subdirectory subtargets that link only as *STATIC* library. For instance, *arch* directory presents *Architecture* target then *Architecture* target has *CPUID*, *IO*, *PORT* and etc. dependencies Exact order of linking targets is: boot.o CRTIBUNDLE <TARGETS> CRTNBUNDLE. Sequence destruction cause to UB. Please to pay attention to this.
