I changed the complier PGI to Intel. But i had some error message p4_error: interrupt SIGSEGV: 11 This error message was occured using intel compiler I don't know what is the ploblem.
View 2 RepliesNeed to handle SIGSEGV error when pbuf size is less than size. inside lib.:
for (i = 0; i < size; i++)
pbuf[i] = i;
My compiler won't find <new>. Since it's such a basic function, I'm a bit confused. Is <new> supposed to be in a file of its own? Where do I find it? And if it turns out to be missing on my computer, where can I find a <new> one? Or do you see anything else that I do wrong?
After some trying out, it seems I can't find stuff like iostream or any other basic stuff either. The compiler is prolly looking for them at the wrong place. Does anyone know how I change or add paths for the compiler to look in when using the "<>" operator?

I'm still a beginner in Linux world, and I would like to learn something more about bash. I installed recently the Intel Fortran compiler. I know where the executable of the compiler is, but I don't know how to make it as a global command, the path is:
/opt/intel/Compiler/11.1/072/bin/intel64/ifort
I would like to write "ifort" in whatever directory and get the compile to do its job. What I know is that this is done by bash. Could someone please explain how this is done?

I'm using Centos 5.4.
I have written a Linux kernel module (in Linux 2.4, Red Hat 9) which does the followings: It takes srcIP, sourceport, destIP, destport and loadvalue as command line arguments. If configured load value is greater than 1, it creates different channels (i.e. No of UDP channels created equals to configured load value), assign different source port and destination port to different channels and send UDP datagram in different channels. Say for example the configured parameters are as follows srcIP=10.17.17.43 destIP= 10.17.17.44 sourceport=10000 destport= 20000 loadvalue=2.
Then it creates two UDP different channels and transmits UDP packets (in every 20 milliseconds) to destination IP address (i.e., 10.17.17.44) with source port 10000, destination port 20000 in one channel and source port 10002, destination port 20000 in another channel. When I configure to pass ?loadvalue=500? and run the module, I get the below kernel panic message in system log file (i.e., var/log/messages) 0>Kernel panic: Aiee, killing interrupt handler! In interrupt handler - not syncing. Running the same linux kernel module ,in 1000 loadvalue, I get this message, eth0: Out-of-sync dirty pointer, 49937 vs. 49954 in text console. I am unable to catch the root cause of these problems and how will I solve these?

Code:
configure: error: Could not find the following X libraries: -lX11 -lXext -lXt

Ctrl-c with middle mouse button (MMB) trigger in running bash script trigger.
The key combination Ctrl-C or "^C" with the keyboard triggered on a running bash script stands for "signal interrupt" (SIGINT) and terminates the process.
For my workflow in the test phase, how I could do that with the MMB-Buffer, followed by the modified script command:
Code: Select allscript runs
script runs
script runs
Signal interrupt and rerun with MMB trigger:
Code: Select all^C; ./script.sh
modified script runs

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

View 2 Replies View RelatedI have upgraded my machine to Karmic, and thereby getting gcc/g++ 4.4 in the process. I have some code that requires gcc/g++ 4.3.
I can change the compiler system wide by redirecting the symbolic link from 4.4 to 4.3
Code:
sudo rm /usr/bin/gcc
sudo ln -s /usr/bin/gcc-4.3 /usr/bin/gcc

I'm reading about GNU CPP(GNU C preprocessor). In the CPP manual -> 1.1 Character sets:
Code:
After preprocessing is complete, string and character constants are converted again, into the execution character set. This character set is under control of the user; the default is UTF-8, matching the source character set. I think "under control of the user" means to use the option -fexec-charset=, right? And in the above part, it says pretty clear: "After preprocessing is complete", so the job -- "string and character constants are converted again, into the execution character set" -- should be done by the C compiler(compilation proper), not GNU CPP. Then the option -fexec-charset= should be an option controlling the C compiler, not the preprocessor. But in the GCC manual, this option is listed in the "3.11 Options Controlling the Preprocessor". I don't understand this, If this option is an option controlling the preprocessor, it conflicts with the CPP manual. How to understand this?
I have a large existing codebase that all compiles under Ubuntu 8.04 with g++ using Scons. I've been given the task of getting it to compile for Arm9 running uclinux. I have a arm-elf-g++ compiler that I need to use instead of the gcc version. I ended up borking my /usr/lib/scons/SCons/Tool/g++.py file to use arm-elf-g++ instead of g++, but I know that this is not correct, as I have to go edit that file every time I change compilers.
These are the 2 lines I switch out:
Code:
compilers = ['arm-elf-g++']
#compilers = ['g++']
I simply can not find anywhere in the scons documentation that indicates how to tell it to use a different compiler. It seems that it would go under "Environment" but beyond that I'm lost. The CPPPATH variable seems like it only tells scons where to find #include files. I suppose I could rename arm-elf-g++ to g++ and just set my path to find that one first, but that seems like a bit of a hack as well. It would also break other things on my machine.
I'm trying to figure out how pthreads are mapped from the compiler to the Linux kernel. The pthread prototypes are found in a compiler header file (pthread.h), yet the kernel would be responsible for scheduling the threads. So, how does the compiler resolve the pthread symbols at compile time?

So for those of you who has built GCC from source would know that you can't install GCC without an existing GCC. So my question is, what would happen if all computers in the world suddenly just died, and all you had was the computer in front of you, and a copy of GCC 4.5. How would you install that?
I ask because I would like to install GCC 4.5 on my old powerbook G4 mac without installing a binary GCC provided by Tiger 10.4 disks. I would like to build GCC from source, without an existing GCC to complicate updating.
