I am trying to build the Linux kernel using   make xconfig   but I get :  $ make xconfig   CHECK qt * Unable to find the QT4 tool qmake. Trying to use QT3 * * Unable to find any QT installation. Please make sure that * the QT4 or QT3 development package ts correctly installed and * either qmake can be found or install pkg-config or set * the QTDIR environment variable to the correct location. * make[1]: *** No rule to make target `scripts/kconfig/.tmp_qtcheck', needed by `scripts/kconfig/qconf.o'.  Stop. make: *** [xconfig] Error 2   So I used Synaptic package tool to install Qt, now there are some of Qt things installed already and some are not. It specifically said to have qmake, I installed from Synaptic, again the same error as above.    How can I know which packages xconfig needs?

I have a problem with PXE booting. I followed  on the Ubuntu help wiki. But I get an error on client machine:  Could not find kernel image: vmlinuz-3.13.0-24-generic   And now, question. This image should be in pxelinux.cfg folder, am I right?

The Software Center in Ubuntu 16.04 (Gnome Software) shows only part of the packages available. While e.g. apt list qtcreator correctly lists the corresponding package a search in Software Center finds nothing.  Is there something misconfigured? I upgraded from 15.10. Until now I have used the old Ubuntu Software Center which worked fine.

I'm having trouble getting clang++ to work as I compile my code. Specifically, I'm getting a make: clang++: Command not found error.  I've run sudo apt-get install llvm, and also sudo apt-get install build-essential and sudo apt-get update. What do I have to do to get clang++ installed?

I want to be able to recreate specific packages by compiling the source code of the package. To compile the source code one has to run the configuration process, followed by the compilation process. I know how to do it, just not what specifics Ubuntu is supplying.  Packages could be Empathy, Banshee or specific libraries for that matter. I can compile them just fine using the (general) information provided at each project site. In a lot of cases I do, however, end up with a build which is just not quite the same as the original one. Slightly different menu options, some functionality functioning differently or not at all, etc.  Is there any source where the configuration and compilation options can be found which are used for the packages included in Ubuntu? Possible also Ubuntu or Debian specific patches.

I am trying to compile  but when I run ./autogen.sh the script terminates with these errors  Checking for required M4 macros...   libtool.m4 not found   glib-gettext.m4 not found   intltool.m4 not found   pkg.m4 not found   gtk-doc.m4 not found   yelp.m4 not found ***Error***: some autoconf macros required to build mate-desktop   were not found in your aclocal path, or some forbidden   macros were found.  Perhaps you need to adjust your   ACLOCAL_FLAGS?   What do I need to do to get rid of these errors? I tired installing the latest versions of inittool, glib, gtk, yelp, etc... but I still get the macros errors.

Firstly, I saw topics such as 'How to install manually a software...' but it did not solve my problem. I've downloaded Scilab 5.4.1 from the official website and I extracted the .tar.gz file into:  /home/scilab-5.4.1  I then tried the commands below, but they gave several errors:  $ cd scalib-5.4.1 $ configure        @1 $ make             @2 $ make install     @3   these gave the following messages in the terminal:  @1: configure: command not found @2: make: *** No targets specified and no makefile found.  Stop. @3: make: *** No rule to make target `install'.  Stop.   I tried following commands:  $ cd scilab-5.4.1 $ cd bin $ scilab   which gave the message:  The program 'scilab' is currently not installed.  You can install it by typing: sudo apt-get install scilab

I am having the same trouble as others getting my Atheros AR8131 Ethernet card recognised by Ubuntu 12.10 on my new HP Pavillion P7-1449 PC. I found the same question where the answer suggested the following:   Download Tarball compact-wireless-3.6.8-1-snpc Run  ./scripts/driver-select alx make sudo make install    The problem is when I run the make command I get the following:  make -C /lib/modules/3.5.0-21-generic/build M=/home/chris/Downloads/compat-wireless-3.6.8-1-snpc modules make: *** /lib/modules/3.5.0-21-generic/build: No such file or directory.  Stop. make: *** [modules] Error 2   Found a link to an alternative patch file (compat-wireless-2012-09-25-pc) but then I get the similar error:  make -C /lib/modules/3.5.0-21-generic/build M=/home/chris/Desktop/compat-wireless-2012-09-25-pc modules make: *** /lib/modules/3.5.0-21-generic/build: No such file or directory.  Stop. make: *** [modules] Error 2   Any help you could provide would be greatly appreciated.

I mainly use the QGis Master (nightly build) for my Debian Linux and I'm quite happy with it. But for educational and demonstration purposes, I now have to work with the Stable(1.8) version.  How can I run a stable QGis 1.8 version in a way that it won't interfere with my other QGis build? The ideal solution will be to run everything just from a folder. This is possible for  (QGis on a Stick), but I haven't found any way to do this on Linux systems. I don't want to use any live-distributions or whole Operating Systems.  I tried to compile QGis stable as shown , but if I try to run it crashes saying:  Warning: !!! prefix path was requested, but it is not valid - we do not run from installed path !!! Segmentation Fault   Most likely it tries to read the configuration files from my .qgis config folder in the home-directory and fails because it can't work with the 1.9dev configurations and prefixes.  How can I work around this?

I'm trying CTest in CMake in order to automatically run some of my tests using make test target. The problem is CMake does not "understand" that the test I'm willing to run has to be built since it is part of the project.  So I'm looking for a way to explicitly specify this dependency.

I've just changed my primary computer from a laptop running XFCE and 19.10 to a desktop running Gnome 3 and 20.04 overall I'm very impressed.  One of the tools I tend to use all the time is Zenmap but I can't locate it in either the software catalogue or via running apt in a terminal window, so I assume it's been removed.   So   What's the rationale for this? Are their issues with Zenmap I should be aware of? Is there a simpler way of installing then the way outlined on Nmap's site (i.e.  ) Is there an alternative application that will let me port scan my LAN (IP address / open TCP port is a must-have, description of service and UDP ports are a nice to have since I'm generally just checking if a known port can be seen)

My  works on Ubuntu (at least for me, and all fatal bugs reported so far are solved), but when I run it on QGIS installed from the official 2.10.1 64-bit installer for Windows (on Windows 7 64-bit), I can't install it due to following error:  This plugin is broken No module named qgsprojectionselectionwidget   Another user reported it this problem as well. but with another error message (I don't know which operation system and architecture does he have, but I'd guess Windows and 64-bit EDIT: I guessed wrong, he has Mac OS X):  This plugin is broken No module named qgsmaplayercombobox   Both refer to widgets in the GUI form, which I built through Qt Designer in Ubuntu. Qt Designer is packed with QGIS installer for Windows as well and claims to contain the same QGIS custom widgets, so the problem shouldn't be in those widgets missing, and QGIS should recognize them - but it doesn't.  So how to fix it? My plugin is still experimental, so I can just add "sorry, doesn't work under Windows" to the metadata, but it's not a real solution.  EDIT: the same behavior confirmed on 32-bit version too.  Now I found a good hint in comment to : use os.path.join to make the paths cross-platform. This is easy for the few hardcoded paths I have, but the errors seems to suggest the problem is deeper, perhaps even in Qt. How can I handle this problem in my plugin without tweaking anything else?

I installed qt5.4 from  in Ubuntu 14.04, but when I run:   qmake -v   I always get the old version Qt5.2.1, although I think it is installed here Qt version 5.4.2 in /opt/qt54/lib. Can anyone tell me how to make sure that Qt5.4.2 is installed properly?   Thanks

It's my second post here, i have a huge problem which prevents me to study so i have to fix it as soon as it's possible ! My gcc was working fine and i had to work on FairThreads (in C). I downloaded the following archive :  As you can see, in /src there's a makeFile, i replaced the second line which was : LIB_DIR     = ../lib  by LIB_DIR     =  /usr/bin/ld and i compiled the makeFile by the command &quot;make&quot; And now, i cannot compile any c/c++ program anymore. Even a hello world program. I got the following error message on the terminal for every compiling attempt : /usr/bin/ld: 2: /usr/bin/ld: Syntax error: newline unexpected collect2: error: ld returned 2 exit status  I have found on the net this solution but it doesn't work for me : sudo apt-get autoremove binutils     sudo apt-get install binutils  I also tried to reinstall gcc, when executing : sudo apt-get purge gcc   i got : Des erreurs ont été rencontrées pendant l'exécution :   linux-firmware   linux-image-generic-hwe-18.04   linux-generic-hwe-18.04 E: Sub-process /usr/bin/dpkg returned an error code (1)  but when i trie a gcc --version it tells me that it is not found. So when i execute the command to reintall it : sudo apt-get install gcc   i also get : Des erreurs ont été rencontrées pendant l'exécution :  linux-firmware  linux-image-generic-hwe-18.04  linux-generic-hwe-18.04  linux-image-5.4.0-72-generic  initramfs-tools E: Sub-process /usr/bin/dpkg returned an error code (1)  but gcc --version tellls that it's installed. Finally, when i trie to compile a program, i got : /usr/bin/ld: 2: /usr/bin/ld: Syntax error: newline unexpected collect2: error: ld returned 2 exit status  I hope that i explained well, and i'll get a solution for this :/, as a computer science student, i can't do anything without gcc :( EDIT 1 : When i try to remove bin/ld by executing : sudo rm -fr /usr/bin/ld;sudo apt-get install --reinstall binutils  i got : Des erreurs ont été rencontrées pendant l'exécution :  linux-firmware  linux-image-generic-hwe-18.04  linux-generic-hwe-18.04  linux-image-5.4.0-72-generic  initramfs-tools E: Sub-process /usr/bin/dpkg returned an error code (1)  and this particular error message : WARNING: no ldd around - install libc-bin  EDIT : I have installed ldd by the command : sudo apt-get install libc-bin  still no changes...
