Can't compile project #2

Closed ghost closed 4 years ago

ghost commented 4 years ago

The make command says

CC kernel/main.c clang: error: unknown argument: '-fstack-size-section' Makefile:116: recipe for target 'build/kernel/kernel/main.o' failed make: *** [build/kernel/kernel/main.o] Error 1

After commenting out CFLAGS += -fstack-size-section I get a lot of

warning: unknown warning option '-Werror=pointer-integer-compare'; did you mean '-Werror=string-compare'? [-Wunknown-warning-option] 1 warning generated.

The compilation stops with

LD build/user/kvs.debug.elf SYMBOLS build/user/kvs.debug.elf STRIP build/user/kvs.elf make: llvm-objcopy: Command not found Makefile:187: recipe for target 'build/user/kvs.elf' failed make: *** [build/user/kvs.elf] Error 127

Fixed it by adding "-6.0" here OBJCOPY := $(LLVM_PREFIX)llvm-objcopy-6.0$(LLVM_SUFFIX)

Then I get

LD build/user/init.debug.elf SYMBOLS build/user/init.debug.elf STRIP build/user/init.elf OBJCOPY build/init.bin llvm-objcopy-6.0: Unknown command line argument '-j.initfs'. Try: 'llvm-objcopy-6.0 -help' llvm-objcopy-6.0: Did you mean '-stats'? llvm-objcopy-6.0: Unknown command line argument '-j.text'.

Makefile:107: recipe for target 'build/init.bin' failed make: *** [build/init.bin] Error 1

After adding a space between all "-j" and "-O" make says

LD build/user/init.debug.elf SYMBOLS build/user/init.debug.elf STRIP build/user/init.elf OBJCOPY build/init.bin llvm-objcopy-6.0: 'build/user/init.elf': The file was not recognized as a valid object file Makefile:107: recipe for target 'build/init.bin' failed make: *** [build/init.bin] Error 1

I don't know what to do. I'm on Linux Mint x64. clang version 6.0.0-1ubuntu2 (tags/RELEASE_600/final)

So I uncommented CFLAGS += -fstack-size-section and created a symlink sudo ln -s /usr/lib/llvm-9/bin/clang /usr/bin/clang and now make says

LLVM/Clang 6.x is too old to build Resea. Could you try with version 8.x or higher?

Also, LLVM_SUFFIX option would be helpful:

$ make LLVM_SUFFIX=-8 run
