I just learned to use ecos to build a i386 redboot follwing the http://ecos. sourceware.org/，and I am confused by what I got:
1. I downloaded the ecos via wget as the instruction of http://ecos.sourceware.org/getstart.html: wget --passive-ftp ftp://ecos.sourceware.org/pub/ecos/ecos-install.tcl and install It,the ecos has been installed with the directory structure such as:ecos/ecos-2.0/packages/hal/i386/arch/ecos-2.0; 2. Then,I got the snapshot via http://www.ecoscentric.com/devzone/snapshots.shtml and reinstalled it ,this time the directory structre is ok as normal mentioned: ecos/packages/hal/i386/arch/current; 3. Then,I use the snapshot version to build the i386 and arm tool chains,and then the redboot for i386 with configtool.exe(Version 0607)----BTW,and I don’t know how to get the configuretool_v1.3.net for MLT---there is a error for building which confusing me so long a time: i386-elf-gcc -c -I/ecos-d/ecos_working/redboot/example_i386_install/include -I/ecos-d/ecos/packages/hal/i386/arch/current -I/ecos-d/ecos/packages/hal/i386/arch/current/src -I/ecos-d/ecos/packages/hal/i386/arch/current/tests -I. -I/ecos-d/ecos/packages/hal/i386/arch/current/src/ -finline-limit=7000 -Wall -Wpointer-arith -Wstrict-prototypes -Winline -Wundef -g -O2 -ffunction-sections -fdata-sections -fno-exceptions -Wp,-MD,src/hal_syscall.tmp -o src/hal_i386_arch_hal_syscall.o /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c: In function 'hal_syscall_handler': /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c:113: warning: implicit declaration of function 'get_register' /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c:113: error: 'EAX' undeclared (first use in this function) /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c:113: error: (Each undeclared identifier is reported only once /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c:113: error: for each function it appears in.) /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c:114: error: 'EBX' undeclared (first use in this function) /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c:115: error: 'ECX' undeclared (first use in this function) /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c:116: error: 'EDX' undeclared (first use in this function) /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c:135: warning: implicit declaration of function 'put_register' /ecos-d/ecos/packages/hal/i386/arch/current/src/hal_syscall.c:145: error: 'SIGTRAP' undeclared (first use in this function) In file included from /ecos-d/ecos/packages/hal/i386/arch/current/src/redboot_linux_exec.c:52: /ecos-d/ecos_working/redboot/example_i386_install/include/redboot.h:66:25: error: cyg/crc/crc.h: No such file or directory make[1]: Leaving directory `/ecos-d/ecos_working/redboot/example_i386_build/hal/i386/arch/current' make[1]: *** [src/hal_syscall.o.d] Error 1 make: Leaving directory `/ecos-d/ecos_working/redboot/example_i386_build' make[1]: *** Waiting for unfinished jobs.... /ecos-d/ecos/packages/hal/i386/arch/current/src/redboot_linux_exec.c: In function 'do_exec': /ecos-d/ecos/packages/hal/i386/arch/current/src/redboot_linux_exec.c:261: warning: implicit declaration of function 'cyg_hal_plf_screen_position' make[1]: *** [src/redboot_linux_exec.o.d] Error 1 make: *** [build] Error 2 4. from the make log,there are two errors which I don’t know why at all because: 1).EAX has been declared in i386_stub.h and this file will be included by hal_syscall.c if CYGSEM_REDBOOT_BSP_SYSCALLS defined,and I am sure that the MACRO CYGSEM_REDBOOT_BSP_SYSCALLS has been defined; 2).the cyg/crc/crc.h:this file will be included in redboot.h,but I couldn’t find this file in this directory,why?could anyone tell me ? 5.I want to rebuild the confiuretool with the latest snapshot version,and I followed the http://www.ecoscentric.com/devzone/configtool.shtml But the $HOME can not be understood by cygwin bash ,why?
