[Solved] Linux Core Compile Error: No rule to make … ipt_ecn.c

Problem phenomenon:

The following error occurred while compiling the kernel:

make[3]: *** No rule to make target 'net/ipv4/netfilter/ipt_ecn.c', needed by 'net/ipv4/netfilter/ipt_ecn.o'
make[2]: *** [net/ipv4/netfilter] Error 2
make[1]: *** [net/ipv4] Error 2
make: *** [net] Error 2

Cause analysis:

The main reason is that the Linux kernel code is decompressed under windows (I think a convenient reference is also needed on Windows), but some files (such as ipt_ecn. C, etc.) are case sensitive. When decompressing on windows, they overwrite each other because they are not case sensitive, resulting in the lack of files.


Just decompress your source code and compile it again. When decompressing under windows, you will be prompted whether the same files need to be processed. Select no for all.
