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@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 On 08/30/2013 08:10 PM, Eddie Kohler wrote: > It looks like your code uses floating-point arithmetic.
