&#39;gmake&#39; refers specifically to GNU make. &#39;make&#39; refers to the system&#39;s default make implementation; on most Linux distros this is GNU make, but on other unixes, it could refer to some other implementation of make, such as BSD make, or the make implementations of various commercial unixes.

The language accepted by GNU make is a superset of the one supported by the traditional make utility.

By using &#39;gmake&#39; specifically you can use GNU make extensions without worrying about them being misinterpreted by some other make implementation.

On my system no difference (gmake is soft link to make):

    -&gt; ls -l $(which gmake make)
    lrwxrwxrwx 1 root root      4 Jun  5  2007 /usr/bin/gmake -&gt; make
    -rwxr-xr-x 1 root root 168976 Jul 13  2006 /usr/bin/make

gmake stands for GNU make. There&#39;re different implementations of make. On Linux machine most probably make will by GNU and to make user&#39;s life isier make is soft linked to gmake.

The usual &quot;opposite&quot; of `gmake` is BSD `make`, which will tend to be `make` on BSD systems, unsurprisingly.  If you want to see what BSD make is like, on Debian derivatives it&#39;s available as `apt-get install pmake`.

Apparently, GNU make is [practically universal now][1], so there should almost never be a difference.

When i use DatePicker, jQuery&#39;s UI plugin, in an existing .aspx page I get errors that:

    $(&quot;#datepicker&quot;).datepicker is not a function

However, when I copy and paste the same code that creates and uses the datePicker to an HTML file that&#39;s also in the same directory as the aspx page, it works flawlessly. This leads me to assume that there are some JS files in the aspx page that&#39;s preventing the datePicker or maybe jQuery&#39;s UI JS files to load properly.

Can anyone confirm my beliefs or provide any tips on finding the culprit that&#39;s interfering with jQuery&#39;s UI plugins?

Here&#39;s a question that I don&#39;t quite understand:

The command, `system(&quot;pause&quot;);` is taught to new programmers as a way to pause a program and wait for a keyboard input to continue. However, it seems to be frowned on by many veteran programmers as something that should not be done in varying degrees.

Some people say it is fine to use. Some say it is only to be used when you are locked in your room and no one is watching. Some say that they will personally come to your house and kill you if you use it. 

I, myself am a new programmer with no formal programming training. I use it because I was taught to use it. What I don&#39;t understand is that if it is not something to be used, then why was I taught to use it? Or, on the flip side, is it really not that bad after all?

What are your thoughts on this subject?

**What strategies can be used in general to decrease build times for any Xcode project? I&#39;m mostly interested in Xcode specific strategies.** 

I&#39;m doing iPhone development using Xcode, and my project is slowly getting bigger and bigger. I find the compile / link phases are starting to take more time than I&#39;d like.

Currently, I&#39;m:

 - Using Static Libraries to make it so
   most of my code doesn&#39;t need to be
   compiled everytime I clean and build
   my main project
   
 - Have removed most resources from my
   application, and test with a hard
   coded file system path in the iPhone
   simulator whenever possible so my
   resources don&#39;t have to constantly be
   packaged as I make changes to them.

I&#39;ve noticed that the &quot;Checking Dependencies&quot; phase seems to take longer than I&#39;d like. Any tips to decrease that as well would be appreciated!


How to decrease build times / speed up compile time in Xcode?

I have an unusual situation where I need to add an arbitrary classpath entry (that points to a jar file) into the manifest of an executable jar. (This is for a Swing desktop application.)

The maven-jar-plugin generates the &quot;Class-Path&quot; entry for the jar manifest using the maven dependencies, and there doesn&#39;t appear to be any way of adding arbitrary entries.

I also looked at hard-coding the arbitrary classpath entry into the batch file that starts the application, using the &quot;-classpath&quot; parameter, but I can&#39;t figure out how to get Maven to filter the classpath into a batch file.

Maven - how can I add an arbitrary classpath entry to a jar?

I am attempting to use the libtommath library. I&#39;m using the NetBeans IDE for my project on Ubuntu linux. I have downloaded and built the library, I have done a &#39;make install&#39; to put the resulting .a file into /usr/lib/ and the .h files into /usr/include

It appears to be finding the files appropriately (since I no longer get those errors, which I did before installing into the /usr directories).

However, when I create a simple main making a call to mp_init (which is in the library), I get the following error when I attempt to make my project:

    mkdir -p build/Debug/GNU-Linux-x86
    rm -f build/Debug/GNU-Linux-x86/main.o.d
    gcc -c -g -MMD -MP -MF build/Debug/GNU-Linux-x86/main.o.d -o build/Debug/GNU-Linux-x86/main.o main.c
    mkdir -p dist/Debug/GNU-Linux-x86
    gcc -o dist/Debug/GNU-Linux-x86/cproj1 build/Debug/GNU-Linux-x86/main.o
    build/Debug/GNU-Linux-x86/main.o: In function &#39;main&#39;:
    /home/[[myusername]]/NetBeansProjects/CProj1/main.c:18: undefined reference to `mp_init&#39;
    collect2: ld returned 1 exit status
    make[2]: *** [dist/Debug/GNU-Linux-x86/cproj1] Error 1

So, it looks like the linker can&#39;t find the function within the library, however it IS there, so I just don&#39;t know what could be causing this.

I get the same error if I type the gcc command directly and skip the makefile, I also made sure the static library got compiled with gcc as well.

Edited to Add:

I get these same errors if I do the compile directly and add the library with -l or -L:

    $ gcc -l /usr/lib/libtommath.a main.c 
    /usr/bin/ld: cannot find -l/usr/lib/libtommath.a
    collect2: ld returned 1 exit status
    
    $ gcc -llibtommath.a main.c 
    /usr/bin/ld: cannot find -llibtommath.a
    collect2: ld returned 1 exit status
    
    $ gcc -Llibtommath.a main.c 
    /tmp/ccOxzclw.o: In function `main&#39;:
    main.c:(.text+0x18): undefined reference to `mp_init&#39;
    collect2: ld returned 1 exit status
    
    $ gcc -Llibtommath.a main.c 
    /tmp/ccOxzclw.o: In function `main&#39;:
    main.c:(.text+0x18): undefined reference to `mp_init&#39;
    collect2: ld returned 1 exit status

I am very rusty on this stuff, so I&#39;m not sure I&#39;m using the right command here, in the -L examples are the libraries being found? If the library isn&#39;t being found how on earth do I get it to find the library? It&#39;s in /usr/lib, I&#39;ve tried it with the .a file in the current directory, etc.  Is there an environment variable I need to set?  If so, how, etc.

I&#39;ve tried a completely different library (GMP) and had the EXACT same problem. This has got to be some kind of Ubuntu environment issue? Anyone have any idea how to fix this?

How could I make my `setup.py` pre-delete and post-delete the build directory?

Cleaning build directory in setup.py

I must be missing something really obvious, but for some reason, the command-line version of the Microsoft C++ compiler (cl.exe) does not seem to support reporting just its version when run.  We need this to write makefiles that check the compiler version a user of our tool has installed (they get makefiles with code they are to compile themselves locally, so we have no control over their compiler version). 

In gcc, you just give the option -v or --version to get a nice version string printed. 

In cl.exe, you get an error for -v. 

I have read the MSDN docs and compiler online help, and I cannot find the switch to just print the compiler version.  Annoyingly, you always get the version when the compiler starts... but you seem not to be able to start the compiler just to get the version out of it.

https://stackoverflow.com/questions/801279/finding-compiler-vendor-version-using-qmake seemed similar, but only deals with the simple case of gcc. 

I am trying this with VC++ Express 2005, if that matters. I hoped it would not, as detecting the compiler version is best done in a compiler-version-independent way :) 

Update, after replies:

 - Running cl.exe without any arguments
   prints its version and some help
   text.  
 - This looks like the most
   portable way to get at the version,
   across vc versions. 
 - You then have to
   parse a multi-line output, but that
   is not too difficult. 
 - We did this in
   the end, and it works.



Finding version of Microsoft C++ compiler from command-line (for makefiles)

I&#39;m trying to figure out the best build system for latex.

Currently, I use [latex-makefile][1], editing in vim, and viewing changes in Okular or gv. The major problem is that it sometimes gets hides errors on me, and I have to run latex manually. The major advantages are that it does all the iteration I need, and offers both pdf and ps simply.

If you have experience with

   * latex-mk
   * vim-latex
   * kile
   * lyx
   * miktex
   * latex-makefile
   * the ultimate latex makefile
   * rubber
   * any others I havent come across

Would you recommend them, and why/why not?

While running 

    ./configure --prefix=/mingw 

on a MinGW/MSYS system for a library I had previously run 

    &#39;./configure --prefix=/mingw &amp;&amp; make &amp;&amp; make install&#39; 

I came across this message:

&gt; WARNING: A version of the Vamp plugin SDK is already installed. Expect worries and sorrows if you install a new version without removing the old one first.  (Continuing)

This had me worried. What&#39;s the opposite of &#39;make install&#39;, i.e. how is a library uninstalled in Linux? Will &#39;make clean&#39; do the job, or are there other steps involved?

I have a MacBook Pro that I&#39;m trying to do some development on.

I have a program I want to build, and when I went to use `make` to build it, I got a &quot;command not found&quot; error. I did some googling and Stack&amp;nbsp;Overflow searches and it doesn&#39;t look like this is a common problem. Why don&#39;t I have `make` installed and how do I get it?

I&#39;m extra confused, because I know I used it relatively recently (in the past month or so) when I was on this laptop.




Using &#39;make&#39; on OS X

I have three files: `program.c`, `program.h` and `headers.h`.

`program.c` includes `program.h` and `headers.h`.

I need to compile this on Linux using _gcc_ compiler.  I&#39;m not sure how to do this. Netbeans created one for me, but it&#39;s empty.

How do I make a simple makefile for gcc on Linux?

Ever since I learned about -j I&#39;ve used -j8 blithely.  The other day I was compiling an atlas installation and the make failed.  Eventually I tracked it down to things being made out of order - and it worked fine once I went back to singlethreaded make.  This makes me nervous.  What sort of conditions do I need to watch for when writing my own make files to avoid doing something unexpected with make -j?

Wildcard targets in a Makefile

Is there a command line way in `make` to find out which of the prerequisites of a target is not updated?

Debugging GNU make

For example, I have something like this in my makefile:

    all:
         cd some_directory

But when I typed `make` I saw only &#39;cd some_directory&#39;, like in the `echo` command.


How do I write the &#39;cd&#39; command in a makefile?

I want to detect a condition in my makefile where a tool is the wrong version and force the make to fail with an error message indicating the item is not the right version.

Can anyone give an example of doing this?

I tried the following but it is not the right syntax:

    ifeq &quot;$(shell svnversion --version | sed s/[^0-9\.]*://)&quot; &quot;1.4&quot;
    $error(&quot;Bad svnversion v1.4, please install v1.6&quot;)
    endif


Thanks.
