Hallo, I tried to compile slmodem-2.9.11-20080625 against a 2.6.25.6-55 kernel (recent Fedora 9 kernel). I got the following problem: make -C modem all make[1]: Entering directory `/root/slmodem/slmodem-2.9.11-20080625/modem' rebuild profile... gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_main.o -c modem_main.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_cmdline.o -c modem_cmdline.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem.o -c modem.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_datafile.o -c modem_datafile.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_at.o -c modem_at.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_timer.o -c modem_timer.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_pack.o -c modem_pack.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_ec.o -c modem_ec.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_comp.o -c modem_comp.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_param.o -c modem_param.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_debug.o -c modem_debug.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o homolog_data.o -c homolog_data.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o dp_sinus.o -c dp_sinus.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o dp_dummy.o -c dp_dummy.c gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o sysdep_common.o -c sysdep_common.c gcc -o slmodemd modem_main.o modem_cmdline.o modem.o modem_datafile.o modem_at.o modem_timer.o modem_pack.o modem_ec.o modem_comp.o modem_param.o modem_debug.o homolog_data.o dp_sinus.o dp_dummy.o dsplibs.o sysdep_common.o gcc -Wall -g -O -I. -DCONFIG_DEBUG_MODEM -o modem_test.o -c modem_test.c gcc -o modem_test modem_test.o modem_cmdline.o modem.o modem_datafile.o modem_at.o modem_timer.o modem_pack.o modem_ec.o modem_comp.o modem_param.o modem_debug.o homolog_data.o dp_sinus.o dp_dummy.o dsplibs.o sysdep_common.o make[1]: Leaving directory `/root/slmodem/slmodem-2.9.11-20080625/modem' make -C drivers KERNEL_DIR=/lib/modules/2.6.25.6-55.dk08.fc9.i686/build make[1]: Entering directory `/root/slmodem/slmodem-2.9.11-20080625/drivers' cc -I/lib/modules/2.6.25.6-55.dk08.fc9.i686/build/include -o kernel-ver kernel-ver.c make all KERNEL_VER=2.6.25.6-55.dk08.fc9.i686 make[2]: Entering directory `/root/slmodem/slmodem-2.9.11-20080625/drivers' make modules -C /lib/modules/2.6.25.6-55.dk08.fc9.i686/build SUBDIRS=/root/slmodem/slmodem-2.9.11-20080625/drivers make[3]: Entering directory `/root/rpmbuild/BUILD/kernel-2.6.25/linux-2.6.25.i686' make[4]: *** No rule to make target `/root/slmodem/slmodem-2.9.11-20080625/drivers/slarm.c', needed by `/root/slmodem/slmodem-2.9.11-20080625/drivers/slarm.o'.
