Test qsim on Mac OS X about qsim HOT 5 CLOSED

is this still a blocker?

from qsim.

I think it still is, there is a reliance on rt lib which doesn't exist for OS X
I made the following change
ifeq ($(UNAME), Darwin)
CXXFLAGS += -DNORT
else
LDFLAGS += -lrt
endif

to alter these three uses
https://github.com/gtcasl/qsim/blob/master/Makefile#L12
https://github.com/gtcasl/qsim/blob/master/Makefile#L43
https://github.com/gtcasl/qsim/blob/master/tests/Makefile#L3

that got me past the linker error, but there appears to be more issues.

You also have to figure out how to build linux kernel on there. Or we could include a pre-built image in the repository.

from qsim.

for linux there maybe a path forward: First you will need to install the Linux source tree on a case-sensitive filesystem on your Mac. (the default HFS filesystem is case insensitive.)
something like this:

sudo hdiutil create -type SPARSE -fs 'Case-sensitive Journaled HFS+' -size {SOME_SIZE} {SOME_NAME}.dmg
sudo hdiutil attach ~/{SOME_NAME}.dmg -mountpoint /Volumes/

then next issue is missing header files from the build I see
cripts/mod/mk_elfconfig.c:4:10: fatal error: 'elf.h' file not found
#include <elf.h>

arch/x86/tools/relocs.harch/x86/tools/relocs.h::1212::1010:: fatal errorfatal error: : 'elf.h''elf.h' filefile notnot foundfound
arch/x86/tools/relocs.h:12:10: fatal error: 'elf.h' file not found
scripts/sortextable.c:23:10: fatal error: 'elf.h' file not found

likely other files may be needed, below is a preliminary list
/usr/include/elf.h
/usr/include/features.h
/usr/include/bits/predefs.h
/usr/include/bits/wordsize.h
/usr/include/gnu/stubs.h
/usr/include/gnu/stubs-64.h

alternatively might be able to get elf with:
brew install libelf
and sed maybe needed aswell:
brew install gnu-sed --with-default-names

Next we will need malloc.h to be where linux expects it to be, can achieve that with a symlink:
sudo ln -s /usr/include/malloc/malloc.h /usr/include/malloc.h

Next issue is the default compiler maybe an issue, may have to
brew install gcc or look into how to do clang linux builds (heard it was possible for the linux kernel, not sure about a debian/centos/etc image.

Maybe easier to do the linux kernel compilation with a linux docker image, no real value in getting the linux image to build natively.
