Makefile does not generate helper executable correctly #5

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. GCC 4.4.5
2. CUDA SDK 4.0.1

The provided makefile does not complete the generation of the helper 
executable. helper.o is generated, but the helper executable does not appear in 
the build directory.

Can you show me the error messages? I am using GCC 4.4.5 with CUDA 4.0.17 and 
it does work. btw: you can clone the latest code from github.

Before opening this issue, I already cloned the code from github, with the same 
result.

If I try to build kgpu using "make all", I don't have the time to see any kind 
of error message (the console is too fast). Conversely, if I switch to the kgpu 
subdirectory and I try to launch "make helper", I obtain the messages in the 
attached files

I'm using Ubuntu 10.10 with a backported lowlatency 2.6.38-8; modules are 
correctly built and loaded, only the helper executable is not generated in the 
build subdirectory.

Sorry I don't understand the language in the attached files. But I am using 
almost exact same system as yours and everything is fine. I tried a clean 
environment, also everything can be built correctly.

Have you ever changed anything, either in kgpu or your global build settings?

ps: my build output looks like this:

Seems like kgpu_log_user.o is not built on your machine, make sure your output 
has such commands(they build kgpu_log_user.o and a static lib):

gcc -O2 -D__KGPU__ -c kgpu_log.c -o kgpu_log_user.o
ar -rcs kgpu_log.a kgpu_log_user.o

Ok, I've better analyzed the error messages, and I think this problem depends 
on some particular problem of my kernel headers (I'm using a non-standard 
Ubuntu kernel, with some patch to get a lowlatecy kernel)

Thanks a lot

Ok, I've tryed with the standard Ubuntu 3.0.1 kernel and the error is not 
disappeared.

The error message is:

$(Q)test -e include/generated/autoconf.h -a -e $@ || (      \
    echo;                               \
    echo "  ERROR: Kernel configuration is invalid.";       \
    echo "         include/generated/autoconf.h or $@ are missing.";\
    echo "         Run 'make oldconfig && make prepare' on kernel src to fix it.";  \
    echo;                               \
    /bin/false)

KGPU doesn't support >=3.0 kernels. But it has nothing to do with the kernel 
configuration unless ecryptfs and AES ciphers are not compiled, which seems 
very rare.

Ok, but I got the same error with 2.6.38.8 kernel

GoogleCodeExporter commented 8 years ago 
Can you show me the result of 'make' under the most-upper level KGPU directory? 
Without that I can't find the problem.

ps, KGPU now uses 2.6.39.4 kernel.

Hi,
I tryed to checkout the last hg revision... but the repository seem to be 
empty...

Original comment by iade.ge...@gmail.com on 10 Sep 2011 at 10:11

GoogleCodeExporter commented 8 years ago 
Yes, it is empty cause KGPU is hosted on github... https://github.com/wbsun/kgpu

It looks like if gcc or ld does not find the CUDA library headers

Hi,
Thanks for the quick reply. I also thought the same thing. Hence I tried to 
make the CUDA samples from the NVIDIA site. They are compiling fine. I am not 
able to understand why kgpu cannot find the libraries.

Which version of the CUDA SDK is installed in your system?

GoogleCodeExporter commented 8 years ago 
Hi,
I have installed CUDA SDK 4.0.17.

Is the SDK in your PATH variable?

Hi,
I was able to resolve the issue. Thanks for helping me in this. I had to add 
-lcublas -lcudart to the following line -
nvcc -link -D__KGPU__ -O2 -arch=sm_20 service.o helper.o kgpu_log_user.o 
gpuops.o -o helper -ldl
in the makefile.

But now I am getting the following error in raid.c file

I think it can be a problem with the kernel headers

Hi,
I was using linux kernel 2.6.38-13. I will check updating it to 2.6.39.4 and 
then try compiling again.

You can also check if the git version you downloaded supports kernels up to a 
specific version.

Hi,
How can I check this?

You can look for this information in the README, if any... I don't try kgpu 
since this summer... but I hope to try it newly soon :D

Hi,
I compiled and kgpu is running properly. I updated the kernel to 2.6.39.4. But, 
as given in the README, if I tried to perform sudo insmod ./ecryptfs.ko it 
gives the following error-
insmod: error inserting './ecryptfs.ko': -1 Device or resource busy

It looks like a problem with a block device in /dev

Hi,
I did not understand it. What might be the problem?

I think the problem is that some device in your /dev is inexistent or busy 
(like reported by the message)

Hi,
I was able to load the dm-crypt.ko file with no problem. Hence, I checked the 
dmesg output, it is giving an error - Failed to register file system. I am 
thinking this might be a problem with ecryptfs.
