The cause of the error is that the compiler is unable to locate the
gobjects.h header file. This file resides in the
The other programs, such as
breakout, can be compiled because the makefile instructions for the compiler (actually the pre-processor) on where to locate the
.h files. You can see this working when you run
make label, the command that executes is:
clang -ggdb -Ispl/include -O0 -std=c99 -Wall -Werror -o label label.c -Lspl/lib -lcs -lm
The relevant parts here are:
-Ispl/include: Inform the pre-processor on where to look for additional
.h files, including
-Lspl/lib: Instructs the linker to link in the spell binary code.
Notice that when you run
make labelTest1, the above are not included, and so the pre-processor and the linker have no way of knowing where to find the relevant SPL headers and library file.
