make: /opt/local/bin/ginstall: No such file or directory

This happened to me while running bundle install on json v1.7.7.
The fix is

# sudo if necessary
ln -s /usr/bin/install /opt/local/bin/ginstall

Overall the installation is pretty smooth, just follow the instructions on Oracle website.
There are two minor hiccups though:
1. cannot touch `/var/lock/subsys/listener’: No such file or directory
This error is cause by the fact there is no /var/lock/subsys directory in some Linux distros, so you need to create one. Before you…

Subj,
It’s buggy and misleading. You will do better by installing Oracle Virtualbox (free) with Linux (free) and running valgrind (free) in the virtual machine.

I’m working on multiple machines under multiple accounts on the same project and using git to sync between the codebases. The program by its nature has to run under root account, so no wonder at some point permissions got screwed up and I’ve got stuck with this error:

I’m working on my next cool project (subscribe to RTFMS.com to find out details) and got stuck with an interesting problem. Here is a fragment of my Makefile:

…
SOURCES := $(wildcard *.c)
…
%.o: %.c %.h
$(I_CC) $(I_CCFLAGS) -c $< ... When I run make clean;make the output is following: gcc -g -I. -I/usr/include -c 1.c gcc...

On some linux machines when you run wireshark you may notice that a lot of packets are marked as invalid (highlighted as black). The contents looks perfectly correct, but for some reason checksum is brkoen and wireshark suggestes that the reason for such unpleasant event is “TCP checksum offload”. Let’s…

I was recently compiling some Arduino code with NewSoftSerial and got hit by infamous “Error: register r24, r26, r28 or r30 required” error. NewSoftSerial is a great library and those using older avr-gcc compiler enjoy it alot. Problem is the newer gcc doesn’t like one nasty error in the code…

If you dare to build OpenOCD from svn trunk and lucky to have a USB JTAG adapter there is a good chance you will see something like

/bin/sh ../libtool –tag=CC –mode=link gcc -std=gnu99 -g -O2 -I/root/Distr/ftd2/libftd2xx0.4.16 -Wall -Wstrict-prototypes -Wformat-security -Wextra -Wno-unused-parameter -Wbad-function-cast -Wcast-align -Wredundant-decls -Werror -o…

This is a famous/popular question in many Linux forums. The typical answer to the question is “Login (especially autologin) into a system as root is bad”. That’s right, but WTH! The person is asking how to do that, not if it is good or bad! If you don’t know the…

In some versions of KDE (like 4.2.2) there is a bug in knote that prevents users from resizing the note. The bug is fixed in 4.2.3, but if you are still using 4.2.2 you still can resize it.

Good news is OpenWRT 8.09 got recently released. Bad news is that you can’t compile it as root. Yes, compiling as root is bad, but in some situations you absolutely need to do that and you’re just unable to do that. In previous versions it was possible to “export FORCE=1”…
