[Click] Kernel : insmod: error inserting

[ndritsos]

Hello ,

yes , i had a function that used floating-point arithmetic , i fixed it 
, and now i have only two warnings :

============================================
1]
CXX [M] myElement.o
/home/dritsos/click/linuxmodule/../elements/local/myElement.cc: In
member function ‘virtual int myElement::initialize(ErrorHandler*)’:
/home/dritsos/click/linuxmodule/../elements/local/myElement.cc:177:1:
warning: the frame size of 1036 bytes is larger than 1024 bytes
[-Wframe-larger-than=]

2]
CXX [M] pem_lib.o
/home/dritsos/click/linuxmodule/../elements/local/pem/pem_lib.cc: In
function ‘int PEM_do_header(EVP_CIPHER_INFO*, unsigned char*, long int*,
int (*)(char*, int, int, void*), void*)’:
/home/dritsos/click/linuxmodule/../elements/local/pem/pem_lib.cc:303:2:
warning: the frame size of 1092 bytes is larger than 1024 bytes
[-Wframe-larger-than=]
============================================


So the compiler ends normaly , BUT again  when i try to run it :
click-install -u test.click

it doesn't work and appears a little bit different  message :

root at dritsos-VirtualBox:~/click/conf# click-install -u test.click
insmod: error inserting '/usr/local/lib/click.ko': -1 Invalid module format
click-install: '/sbin/insmod /usr/local/lib/click.ko' failed


Any idea, what this new message means?

thanks in andvance
