Hello i recompiled my kernel to linux-2.6.23.9lw so i can install madwifi i have installed this: [quote]kernel-devel krb5-devel libstdc++-devel openssl-devel make svn gcc++ kernel-headers[/quote] i followed this: [quote]ifconfig ath0 down ifconfig wifi0 down rmmod ath_pci svn checkout [url="http://svn.madwifi.org/madwifi/branches/madwifi-hal-0.10.5.6/"]http://svn.madwifi.org/madwifi/branches ... -0.10.5.6/[/url] madwifi-ng cd madwifi-ng wget [URL]http://patches.aircrack-ng.org/madwifi-ng-r3745.patch[/URL] patch -Np1 -i ./madwifi-ng-r3745.patch ./scripts/madwifi-unload make make install depmod -ae modprobe ath_pci[/quote] the problem is that when i try to make i get this error: [quote]/bin/sh: line 0: cd: /lib/modules/2.6.23.9lw/build: No Such file or directory Mkaefile.inc:66: *** /lib/modules/2.6.23.9lw/build is missing please set KERNEL PATH. Stop.[/quote] So i use this the make kernelpath command and it compiles fine but when i try to 'make install' i still get this error: [quote]/bin/sh: line 0: cd: /lib/modules/2.6.23.9lw/build: No Such file or directory Mkaefile.inc:66: *** /lib/modules/2.6.23.9lw/build is missing please set KERNEL PATH. Stop.[/quote] also when i try to compile aircrack i get error with 'make install' again but not with 'make': [quote]install -d /usr/local/bin make[1]: install: command not found make[1]: *** [install] Error 127[/quote] any help much appreciated
