Hi, I notice a year old bug in bugzilla [1]. As many developers don't take a look on it, I decided to forward the bug by mail. And to reach the reporter, you must log in to bugzilla. Quoting from the bug report: > Christian 2022-04-08 10:44:17 UTC > > Symptom: > > make[2]: Entering directory '/usr/src/kernels/5.17.1-1.el8.elrepo.x86_64' > Makefile:729: target 'include/config/auto.conf' does not exist > test -e include/generated/autoconf.h -a -e include/config/auto.conf || ( \ > echo >&2; \ > echo >&2 " ERROR: Kernel configuration is invalid."; \ > echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\ > echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \ > echo >&2 ; \ > /bin/false) > Makefile:1717: target 'prepare' does not exist > if [ "gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-4)" != ""gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-4)"" ]; then \ > echo >&2 "warning: the compiler differs from the one used to build the kernel"; \ > echo >&2 " The kernel was built by: "gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-4)""; \ > echo >&2 " You are using: gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-4)"; \ > fi > /bin/sh: -c: line 0: syntax error near unexpected token `(' > /bin/sh: -c: line 0: `if [ "gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-4)" != ""gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-4)"" ]; then \' > make[2]: *** [Makefile:1717: prepare] Error 1 > make[2]: Leaving directory '/usr/src/kernels/5.17.1-1.el8.elrepo.x86_64' > > > Note the double double-quotes in the GCC Version comparison ! > > This happens to me when I try to compile vmware kernel modules with mainline kernel from elrepo on AlamLinux8. > > Since it is coming from the Makefile of the Kernel, I suppose this is the proper upstream tracker to be used.
