Jacques & others bilingual, Please converse with Giuseppe in Italian and then report back to the List. The issues are as follows: 1) It is understood the slusb.ko is compiled on a x86_64 system with 64 bit resources. 2) The patch of modem/Make implements gcc -m32 so that slmodemd is compiled in 32 bit mode. But does this require that some 32 bit libraries be installed, or do the 64 bit libraries installed on a x86_64 system suffice? What ever is working for the slusb driver functionality, should be expected to work for the ALSA modem drivers, are they are fully Open Source and should compile cleanly on a 64 bit System. Guiseppe, Being a biologist by training and an administrator in current work, I am not knowledgeable in deeper coding issues.
