How to find apt in Ubuntu

So I was looking for the Xerces-c Compiler library so I could run blahtex and make a nicer epub for my poker book (below)




















because I wrote it with LaTex using Olaf's cool poker card style file.

The biggest problem with package management tools like yum and apt / apt-get  for linux and their databases of really what are source files is a very simple problem; over time the developers - all eager beavers - change the names or upgrade versions of that same library set and that causes people constant problem of finding the right packages to install.   The Linux user community is so large and effective that this is a constant problem.  Lots of people take on old software and make it better. Just try installing GCC and see what I mean.  Half my Google searches are a direct result of not knowing the name of the packages.

So today while working on my ubuntu machine, I found a way to search the database for a fragment that might make sense. 

apt-cache search libxerces

I was able to look into the database and find this:



 apt-cache search libxerces

libxerces2-java - Validating XML parser for Java with DOM level 3 support
libxerces2-java-doc - Validating XML parser for Java -- Documentation and examples
libxerces2-java-gcj - Validating XML parser for Java with DOM level 3 support (native code)
libxerces-c-dev - validating XML parser library for C++ (development files)
libxerces-c-doc - validating XML parser library for C++ (documentation)
libxerces-c-samples - validating XML parser library for C++ (compiled samples)
libxerces-c2-dev - validating XML parser library for C++ (development files)
libxerces-c2-doc - validating XML parser library for C++ (documentation)
libxerces-c28 - validating XML parser library for C++
libxerces-c3.1 - validating XML parser library for C++

So if you are looking into a Debian/Ubuntu based distribution with apt then try the apt-cache search.

Font OMS/jkp/m/n/10=jkpsy at 10.0pt not loadable: Metric (TFM) file not found Error Latex Fedora 18

I was compiling the kpfonts into a LaTeX document on Fedora 18 and got the following errors:

...

I wasn't able to read the size data for this font,

so I will ignore the font specification.

[Wizards can fix TFM files using TFtoPL/PLtoTF.]

You might try inserting a different font spec;

e.g., type `I\font<same font id>=<substitute font name>'.

I saw some posts claiming to install texlive-fontrecommend like this:

sudo yum install texlive-collection-fontsrecommended texlive-times


but they were updated and installed. The packages I installed were all wildcard * font packages like this:

sudo yum install texlive-collection-fonts*

then I ran

sudo texhash

and for Lyx I reconfigured and it worked.

Printing JPEG files to Epson XP-400 printer

So I was trying to print out my tickets for the Rockstar Mayhem concert when the Windows machine I was trying to use stalled.

http://rockstarmayhemfest.com/dates/phoenix-az-2

So I used Fedora on my laptop to save the day.

I couldn't get the pdf ticket files to print on the networked Epson XP-400.

Instead, I loaded them into GIMP and exported them to JPEG format.  Unfortunately, that didn't work.


In the Epson printer manual,
(https://files.support.epson.com/pdf/xp400_/xp400_ug.pdf )
it says:

You can insert memory cards in your product containing files that meet these specifications.

File format JPEG with the Exif version 2.3 standard Image size 80×80 pixels to 9200×9200 pixels

Number of files Up to9990

So I re-exported them and made sure they were in unoptimized uninterlaced format JPEG.  That worked, they were recognized.

So convert PDF to raw JPEG, and load them onto an SD ram card and you can get the printer to print out pages.

USB Keyboard problems on the Dell Optiplex 9020 - use the mini-DIN ports!

I had a problem getting the boot menu and the system menu to appear while rebooting a Dell Optiplex 9020.

According to the manual here, the System menu in BIOS comes up with the F2 key and the boot menu comes up with the F12 key. But when I plugged a USB keyboard in, I could not get those options to appear before it booted Windows.

I noticed mini DIN keyboard and mouse connectors on the back; Why would a brand new computer have a really old interface? So, I found a mini-DIN keyboard and plugged it in. It works, now you can get the data to the BIOS before the DOS / Windows takes over.

My diagnosis is that the BIOS does not initialize the USB device in the proper sequence early enough so that you can use the keyboard in time, perhaps that's why they included mini-DIN interfaces? Great design feature, Dell!

Simple way to add doxygen to your GNU Autotools project

[Edited with changes in Autotools 2016...]

I tried Oren Ben-Kiki's doxygen support here and got some errors when trying doxygen generation inside a directory that wasn't source code directory because of the way it's configured. So here is my simple version:


1. inside top source dir execute:

doxygen -g

to generate Doxyfile.

2. copy that to Doxyfile.in

3. edit Doxyfile.in with the following variables inserted where it makes sense:

PROJECT_NAME = @PACKAGE@

PROJECT_NUMBER = @VERSION@

OUTPUT_DIRECTORY = doxygen

down halfway in the doxygen.in file change

INPUT = @SRC_SUBDIRS@

Then, inside configure.ac insert:

SRC_SUBDIRS = src
# shell script to find directories
for FILE in `ls -d src/*`
do
case "$FILE" in
autom4te* ) continue ;; #
doxygen* ) continue ;; # exclude doxygen dir
*Makefile* ) continue ;; # exclude doxygen dir
m4*) continue ;; #
* )
SRC_SUBDIRS+=" $FILE"
esac
done

at the bottom of configure.ac:

AC_SUBST([SRC_SUBDIRS])

and make sure you add the target doxygen file (it will start with doxygen.in and generate doxygen)

# OUTPUT STAGE
AC_CONFIG_FILES([Makefile Doxyfile])

Then inside your Makefile.am add:

EXTRA_DIST += Doxyfile.in

# simple doxygen target
dox: Doxyfile.in
doxygen Doxyfile


# clean up the extras including doxygen
clean-local:
cd ${top_srcdir}
rm -rf doxygen

now when you

make clean

it will remove the doxygen directory.
When you

make dox

it will run doxygen and make html and latex outputs. You will need to configure other changes to the doxygen to get specific output but this will get you started fast...

GNU Autotools make dist-bz2

If you are making a GNU autotools / automake package, the make command to make a bzip2 compressed distribution tarball is make dist-bzip2

Solution:

The answer is who has access to the /usr/share/autoconf folders and root has the default access.

If you can't see them, then sudo autoscan instead of autoscan and so on...

then run:

sudo autoconf
sudo automake etc. 


OR

add your compiling user into the root group.
