Hi , I have a test_1.c file which includes <camkes.h> camkes.h which is automatically generated has following includes #include <camkes/dataport.h> #include <camkes/error.h> #include <stdint.h> #include <stdlib.h> #include <utils/util.h> #include <platsupport/io.h> and another file test_2.c which includes "socket.h" In CMakeLists.txt, where I compile my test_1.c and test_2.c looks like this DeclareCAmkESComponent(test INCLUDES "../muslibc/include/sys"* // necessary for compilation as test_2.c has "socket.h"* SOURCES "test_1.c" "test_2.c" C_FLAGS -Wall -Werror LIBS seos_libs ) However when I compile , I start getting these errors: In file included from ../projects/util_libs/libplatsupport/include/platsupport/io.h:20:0, from projects/test/include/camkes.h:20, from ../projects/src/test_1.c:8: ../projects/musllibc/include/sys/errno.h:1:2: error: #warning redirecting incorrect #include <sys/errno.h> to <errno.h> [-Werror=cpp] *#warning redirecting incorrect #include <sys/errno.h> to <errno.h>* ^~~~~~~ In file included from ../projects/musllibc/include/sys/errno.h:2:0, from ../projects/util_libs/libplatsupport/include/platsupport/io.h:20, from projects/test/include/camkes.h:20, from ../projects/src/test_1.c:8: ../projects/musllibc/include/sys/errno.h:1:2: error: #warning redirecting incorrect #include <sys/errno.h> to <errno.h> [-Werror=cpp] #warning redirecting incorrect #include <sys/errno.h> to <errno.h> How could this be solved ? thanks --yk

"../muslibc/include/sys" // necessary for compilation as test_2.c has "socket.h"
This line shouldn't be here, and instead socket.h should be included via <sys/socket.h>. Otherwise many other include directives are going to match on the incorrect files.
