gera-gas / crosslib

Software project with cross compile library for embedded system.

crosslib

Software project with cross compile library for embedded system. Library collections contain:

• devlib -- drivers for any devices and hardware modules.
• gcclib -- part of standard GCC compiler files.
• libc -- some files standard C library.
• syslib -- library for system creation. (Pseudo thread, simple and fast non-blocking lock-free mechanism, HAL, IO, etc).

Tools

• CMake version 2.8.7+
• GNU Make

Configure

List CMake definitions for config project.

-DBUILD_DEMO

Build demo executables. It can be used only for MinGW build. Because in examples used a Windows mechanisms.

-DASSERT=[0,1,2]

Defined to control assert macros.

• 0 -- kick all assert macros from source code (default).
• 1 -- add simple assert macros with halt only (recommended for raw system).
• 2 -- add assert macros with output to STDOUT by fprintf.

-Dint[bits]=[C-type name]

Set specific bitness types in typedef.h. Default:

• -Dint8=int8_t
• -Duint8=uint8_t
• -Dint16=int16_t
• -Duint16=uint16_t
• -Dint32=int32_t
• -Duint32=uint32_t
• -Dint64=int64_t
• -Duint64=uint64_t

-DNOSTDINC_STDINT_H

Kick standard include header file - stdint.h.

-DUSE_BUILTIN_LIBC

Enable using builtin LIBC functions from GCC compiler. Else LIBC will be used from [app]/[libc].

-DUSE_REGEXP_LOCALE

Enable using compare in regular expression by locale mechanism. If locale and USE_BUILTIN_LIBC is not set, compare using only C locale (ASCII).

-DCPUINIT_CXX

Including C++ global initialization/deinitializtion code into CPU boot code of [devlib]/[cpu]/[...].

-DCXX_RTTI

If defined, build class with RTTI supports.

-DCFG_ERROR_DETAILS

Enable fatal error details store. Error details: source code file, line, function name.

Build

Library building is expected as part of your top CMake project. Examples of standalone build you can find in [tools] directory. Below shown example standalone build.

$ mkdir build
$ cd build
$ cmake -Wno-dev -G "Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=../config/<toolchain>.cmake ..
$ cmake --build .
$ make install

After installing libraries and headers will be copied to [build]/[export].

Note

Library oriented on GCC compiler.
