ddump-rule-firings output when building Haskell program with Stack - haskell

How do I see the output of -ddump-rule-firings when building a program with stack?
I've added -ddump-rule-firings to ghc-options in my .cabal file and run stack clean; stack build -v. The rule firings (and any other output from ghc) are not included in the output of stack.
The normal ghc output doesn't seem to be logged anywhere in the .stack-work directory.
Other developers have encountered similar issues, but the proposed change (adding a --dump-logs option) doesn't seem to be implemented:
>stack build --dump-logs
Invalid option `--dump-logs'
Usage: stack build [TARGET] [--dry-run] [--pedantic] [--fast]

.stack-work\dist\ca59d0ab\build\iterate-strict-exe\iterate-strict-exe-tmp\app\Main.dump-rule-firings

Why do OpenGL-based VTK targets in drake executed via `bazel test` sometimes fail on Linux?

While a binary works with bazel run, when I run a test using bazel test, such as:
$ bazel test //systems/sensors:rgbd_camera_test
I encounter a slew of errors from VTK / OpenGL:
ERROR: In /vtk/Rendering/OpenGL2/vtkXOpenGLRenderWindow.cxx, line 820
vtkXOpenGLRenderWindow (0x55880715b760): failed to create offscreen window
ERROR: In /vtk/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx, line 816
vtkXOpenGLRenderWindow (0x55880715b760): GLEW could not be initialized.
ERROR: In /vtk/Rendering/OpenGL2/vtkShaderProgram.cxx, line 453
vtkShaderProgram (0x5588071d5aa0): Shader object was not initialized, cannot attach it.
ERROR: In /vtk/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx, line 1858
vtkXOpenGLRenderWindow (0x55880715b760): Hardware does not support the number of textures defined.
May I ask why this happens?
(Note: This post is a means to migrate from http://drake.mit.edu/faq.html to StackOverflow for user-based questions.)
The best workaround at the moment is to first mark the test as as local in the BUILD.bazel file, either with local = 1, or tags = [.., "local"]. Doing so will make the specific target run without sandboxing, such that it has an environment similar to that of bazel run.
As an example, in systems/sensors/BUILD.bazel:
drake_cc_googletest(
name = "rgbd_camera_test",
# ...
local = 1,
# ...
)
If this does not work, then try running the test in Bazel without sandboxing:
$ bazel test --spawn_strategy=standalone //systems/sensors:rgbd_camera_test
Please note that you can possibly add --spawn_strategy=standalone to your ~/.bazelrc, but be aware that this means your development testing environment may deviate even more from other developer's testing environments.

How to put an extra file in the kernel image by yocto

I have a trouble of putting my initramfs.cpio in my kernel image by yocto.
I have two bb files, one is used to build an initramfs, and the other one is used to build a fitimage.
I successful to build the fitimage bundled with my initramfs image.
But it always failed to build a fitImage that has an initramfs.cpio.gz in the /usr directory in the fitImage.
( I mean, I want to see a file named initramfs.cpio in the /usr when I use my fitImage booting to console )

I have found similar questions:

Any information would be appreciate !!
Thanks !!
The error seems to QA issues it means the source is compiled but not adding to rootfs. Add below line to yourkernel-image.bb. it will solve the issue.
FILES_${PN} += "${exec_prefix}/*"
Note: may be In your kernel.bb file you have given wrong format

QEMU simple backend tracing dosen't print anything

I'm doing get simple trace file from QEMU.
I followed instructions docs/tracing.txt
with this command "qemu-system-x86_64 -m 2G -trace events=/tmp/events ../qemu/test.img"
i'd like to get just simple trace file.
i've got trace-pid file, however, it dosen't have anything in it.
Build with the 'simple' trace backend:
./configure --enable-trace-backends=simple
make
Create a file with the events you want to trace:
echo bdrv_aio_readv > /tmp/events
echo bdrv_aio_writev >> /tmp/events
Run the virtual machine to produce a trace file:
qemu -trace events=/tmp/events ... # your normal QEMU invocation
Pretty-print the binary trace file:
./scripts/simpletrace.py trace-events trace-* # Override * with QEMU
i followd this instructions.
please somebody give me some advise for this situation.
THANKS!
I got same problem by following the same document.
https://fossies.org/linux/qemu/docs/tracing.txt
got nothing because
bdrv_aio_readv and bdrv_aio_writev was not enabled by default, at least the version I complied, was not enabled. you need to open trace-events under source directory, looking for some line without disabled, e.g. I using:
echo "load_file" > /tmp/events
Then start qemu,
after a guest started, I run
./scripts/simpletrace.py trace-events trace-Pid
I got
load_file 1474.156 pid=5249 name=kvmvapic.bin path=qemu-2.8.0-rc0/pc-bios/kvmvapic.bin
load_file 22437.571 pid=5249 name=vgabios-stdvga.bin path=qemu-2.8.0-rc0/pc-bios/vgabios-stdvga.bin
load_file 10034.465 pid=5249 name=efi-e1000.rom
you can also add -monitor stdio to qemu command line, after it started, you can the following command in qemu CLI:
(qemu) info trace-events
load_file : state 1
vm_state_notify : state 1
balloon_event : state 0
cpu_out : state 0
cpu_in : state 0
1 means enabled events.
Modify the trace-events file in the source tree
As of v2.9.0 you also have to remove the disable from the lines you want to enable there, e.g.:
-disable exec_tb(void *tb, uintptr_t pc) "tb:%p pc=0x%"PRIxPTR
+exec_tb(void *tb, uintptr_t pc) "tb:%p pc=0x%"PRIxPTR
and recompile.
Here is a minimal fully automated runnable example that boots Linux and produces traces: https://github.com/cirosantilli/linux-kernel-module-cheat
For example, I used the traces to count how many boot instructions Linux has: https://github.com/cirosantilli/linux-kernel-module-cheat/blob/c7bbc6029af7f4fab0a23a380d1607df0b2a3701/count-boot-instructions.md
I have a lightly patched QEMU as a submodule, the key commit is: https://github.com/cirosantilli/qemu/commit/e583d175e4cdfb12b4812a259e45c679743b32ad

freebsd customized port tree can not build ports from category level

Freebsd 9.1 RC3
just for clarification first: the top level is at /usr/ports, the category level is at /usr/ports/devel
I am working on customized ports tree. Basically, just trim the original whole ports tree to what we need. And, for the most part, it is the same, like GIDs, UIDs, Mk/, Tools/, Templates, and in term of Makefile, I just change SUBDIR to what we need.
General Problem: for each individual ports, like running 'make install clean' at /usr/ports/devel/protobuf, everything works. But, the thing is that running 'make install clean' at category level, it breaks.
Actual Problem:
run 'make install clean -DBATCH' at usr/ports/devel
....

By referring http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/ports-using.html
Note: You can build all the ports in a category or as a whole by running make in the top level directory, just like the aforementioned make fetch method. This is dangerous, however, as some ports cannot co-exist. In other cases, some ports can install two different files with the same filename.
Hope someone can help me out, thanks !
I hope you've resolved this by now. If not, freebsd-ports#freebsd.org or hackers#freebsd.org would be the best places to get answer to such questions.
It looks like at the time the help2man port was out of date/broken. Additionally, when adding or removing categories and directories from ports, you need to edit Mk/bsd.port.mk to update the relevant list.
It's also possible that some ports have dependencies on ports that were removed. You can try running make index and see if it can cleanly build the index or not. This is a good clue on stability of at least default options in ports. (conditional dependencies wont' get tested) Running portlint can also help validate a port and it's dependencies look OK.

linux "make oldconfig" discards an entry CONFIG_K8_NB

I have a .config in the top directory with CONFIG_k8_NB=y, however, after I type "yes "" | make oldconfig", the "CONFIG_k8_NB=y" is gone.
I am certain the CONFIG_k8_NB can be supported by the kernel.
I have found why, it's caused by the dependency of the configuration:
in arch/i386/Kconfig
config K8_NB
def_bool y
depends on AGP_AMD64
we should add:
CONFIG_AGP=y
CONFIG_AGP_AMD64=y
to enable K8_NB
there is a pointer talking about the issue:
