hello everyone,
i am new buddy in ecos world. i have downloaded ecos-1.3.1-1.i386.rpm
from ecos homesite.and running it in redhat linux 9.
using ecosconfig command line utility i prepared build tree for
sythetic linux target. in /ecos-work/
------------------------------------------------------------------------------------
[root@localhost /]# mkdir ecos-work
[root@localhost /]# cd ecos-work/
[root@localhost ecos-work]# ecosconfig new linux
[root@localhost ecos-work]# ls ecos.ecc
------------------------------------------------------------------------------------
my gcc version is as follows so as specified in the tutorials i cahnged
CYGBLD_GLOBAL_COMMAND_PREFIX in ecos.ecc to "".
------------------------------------------------------------------------------------
[root@localhost root]# gcc -v Reading specs from
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/specs Configured with:
../configure
--prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info
--enable-shared --enable-threads=posix --disable-checking
--with-system-zlib --enable-__cxa_atexit --host=i386-redhat-linux
Thread model: posix
gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
[root@localhost root]#
----------------------------------------------------------------------------------
build tree is completed & finally use 'make' to give header files
libraries in /ecos-work/install/include & /ecos-work/install/lib.
finally i
want to run hello world application in /try/hello.c but i got following errors
----------------------------------------------------------------------------------
