Error during SystemC compilation
I'm using Linux Mint 10 / Ubuntu 10.10 and I was getting an error during SystemC compilation. The error was:
make[3]: Entering directory `/home/sergio/a/systemc-2.2.0/src/sysc/utils' g++ -I. -I. -I. -I../../../src -Wall -DSC_INCLUDE_FX -O3 -c -o sc_utils_ids.o `test -f 'sc_utils_ids.cpp' || echo './'`sc_utils_ids.cpp sc_utils_ids.cpp: In function ‘int sc_core::initialize()’: sc_utils_ids.cpp:110: error: ‘getenv’ is not a member of ‘std’ sc_utils_ids.cpp:111: error: ‘strcmp’ was not declared in this scope sc_utils_ids.cpp: At global scope: sc_utils_ids.cpp:119: warning: ‘sc_core::forty_two’ defined but not used make[3]: *** [sc_utils_ids.o] Error 1 make[3]: Leaving directory `/home/sergio/a/systemc-2.2.0/src/sysc/utils' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/sergio/a/systemc-2.2.0/src/sysc' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/sergio/a/systemc-2.2.0/src' make: *** [all-recursive] Error 1
I found a solution at Fedora Forum (thanks to YamlaJ user).
Edit systemc-2.2.0/src/sysc/utils/sc_utils_ids.cpp file adding these two includes:
#include "string.h" #include "cstdlib"
Now you can proceed with make ; make install and test with:
cd examples/sysc/rsa make check
Bluespec Syntax Highlighting for Vim
Here goes a little tip for those who like to use Vim editor to program in Bluespec but gets bored with all your code in gray lines.
Just copy the directory structure inside of $BLUESPEC_HOME/util/vim/ to your home .vim directory (~/.vim) to get syntax highlighting working for bsv files.
mkdir ~/.vim # Only if you don't have vim directory yet.
cd $BLUESPEC_HOME/util/vim/
cp -r * ~/.vim
Now you don't need to load Bluespec Workstation just to get some color in Vim editor

Timer Bash Script
I've used this script to wait a download (through Firefox or Chromium) finishes then shutdown my PC.
while true do sleep 10; if [ ! -e YourFile.zip.part ] ; then init 0; fi done

MySQL command line backup and restore
Backup:
$ mysqldump -u root -p -v DB_NAME > BkpDec2010.sql
Restore:
$ mysql -u root -p DB_NAME < BkpDec2010.sql
To create a database:
$ mysqladmin -u root -p create DB_NAME
Putting the USB Blaster to work on Linux
You'll need to edit rc.local file and create a new one in udev rules:
1) edit rc.local (sudo vi /etc/rc.local) and append the following lines before "exit 0" line.
mount --bind /dev/bus /proc/bus ln -s /sys/kernel/debug/usb/devices /proc/bus/usb/devices
2) create altera-usb-blaster.rules file (sudo vi /etc/udev/rules.d/altera-usb-blaster.rules) with this line:
ATTR{idVendor}=="09fb", ATTR{idProduct}=="6001", MODE="666"

EDIT1: To check if it's working properly execute jtagconfig. You can found it inside Quartus bin folder. If necessary, sudo killall jtagd.
EDIT2: There's an alternative to put usb blaster working on Linux. I've got this tip on Altera Forum but I have not tested yet.
sudo ln -s /sys/kernel/debug/usb/devices /dev/bus/usb/devices
sudo vim <altera path>/quartus/linux/jtagd :%s/\/proc\/bus\/usb\/%03u\/%03u/\/dev\/bus\/usb\/%03u\/%03u\n/ :%s/\/proc\/bus\/usb\/devices/\/dev\/bus\/usb\/devices\n/ :wq
sudo vim <altera path>/quartus/linux64/jtagd :%s/\/proc\/bus\/usb\/%03u\/%03u/\/dev\/bus\/usb\/%03u\/%03u\n/ :%s/\/proc\/bus\/usb\/devices/\/dev\/bus\/usb\/devices\n/ :wq
Altera Quartus II 10.0 installation
Version 10.0 of Altera's products crash during installation on Linux environment. The workaround is to remove the file libX11.so.6 before starting the installer. So, follow this steps:
1) bash ./10.0_quartus_free_linux.sh --noexec
2) cd 10.0_quartus_free_linux
3) rm altera_installer/bin/libX11.so.6
4) sudo bash ./setup
PS: Step 1 is to decompress all installer files.
EDIT: if you got error on step 4, type: sudo -i; export DISPLAY=:0.0; ./setup
