Configuration script for the fx calculator standard C library.
|
||||
Usage: $0 [OPTION]...
|
||||
|
||||
You should build out-of-tree by creating a build directory and configuring from
|
||||
there.
|
||||
|
||||
Debug the fxlibc
|
||||
--debug Enable valgrind flags (-g3)
|
||||
--unit-test Check C-functoon validity with Criterion
|
||||
|
||||
Build options:
|
||||
--toolchain=TRIPLET Build with a different toolchain
|
||||
[sh-elf-gcc] (or [gcc] when the '--unit_test' flag is set)
|
||||
--cflags=FLAGS Additional compiler flags at end of command
|
||||
--prefix=PREFIX Install prefix (PREFIX/lib and PREFIX/include are used)
|
||||
|
||||
ABI support:
|
||||
--support=<target>,<target>, ...
|
||||
Support all <target> ABI if supported by the library.
|
||||
|
||||
target-list:
|
||||
* vhex
|
||||
Enable the Vhex kernel support
|
||||
* fx9860g, fxcg50
|
||||
Enable the support of the Casio' ABI
|
||||
|
||||
fx9860 covers all fx-9860G II-like monochromes models that support
|
||||
addins or can be flashed with an OS that does. This includes SH3 and
|
||||
SH4 machines.
|
||||
|
||||
fxcg50 covers just the fx-CG 50; there is some unofficial compatibility
|
||||
with fx-CG 10/20. All of these are SH4-only.
|
||||
|
||||
The 'ABI support' is used to allow some part of the code, in particular the
|
||||
'unistd' part, I/O management and additionals feature. (like process, fs, ...).
|
||||
|
||||
Format:
|
||||
--static Generate static libraries (default)
|
||||
--dynamic Generate dynamic libraries (Vhex kernel dependant)
|
||||
|
||||
Little note for the generation of dynamic libraries. The superH toolchain currently
|
||||
used (GCC) does not support the '--shared' flags when the archive is build. So we
|
||||
need to create manually an archive that can be used like a shared library.
|
||||
|
||||
To do this we need to do several steps:
|
||||
1) build the sources with the PIE mode as if it were a executable without entry point.
|
||||
2) manually extract symbols defined as 'global' from the generated ELF.
|
||||
3) we create "stubs": functions that will have the same name than the wanted shared
|
||||
libraries and will call internal VHEX loader primitives with the libraries
|
||||
name, function address and size, etc....Then the loader will load the shared
|
||||
function and override the "user function (stub)" to force it to jump into
|
||||
the "real" function (trampoline).
|
||||
4) all generated stubs will be compiled and linked through a static lib that SHOULD
|
||||
be used in the user program which uses the "dynamic library"
