-This is a collection of some of the frequently asked question
-about uClibc. Some of the questions even have answers. If you
-have additions to this FAQ document, I'd love to add them,
-
- -Erik
-
-
-Q: What platforms does uClibc run on?
-
- Currently uClibc runs on arm, i386, m68k, mipsel, powerpc, sh,
- sparc, and v850.
-
-
-
-Q: Does uClibc support shared libraries?
-
- Yes. uClibc has shared library support on x86, arm, and powerpc.
- Shared Libraries are _not_ currently supported on MMU-less systems.
-
-
-
-Q: Why is it called uClibc?
-
- The letter 'u' is short for the greek letter "mu". "Mu" stands for
- "micro", and the "C" is for "controller". uClibc was originaly created to
- support uClinux, a port of Linux for MMU-less microcontrollers such as the
- Dragonball, Coldfire, and ARM7TDMI.
-
-
-
-Q: Can I use it on my desktop x86 system?
-
- Sure! In fact, this can be very nice during development. By using it on
- your development system, you can be sure that the code you are working on
- will actually run on your target system.
-
-
-
-Q: Why are you doing this? Whats wrong with glibc?
-
- The inital reason, is that glibc does not support MMU-les systems. But
- additionaly, the GNU C library has a different set of goals then uClibc.
- The GNU C library is a great piece of software. It complies with just
- about every standard ever created, and runs on just about every operating
- system as well -- no small task! But there is a price to be paid for that.
- It is quite a large library, and keeps getting larger with each release.
- It does not even pretend to target embedded systems. To quote from Ulrich
- Drepper, the maintainer of GNU libc: "...glibc is not the right thing for
- [an embedded OS]. It is designed as a native library (as opposed to
- embedded). Many functions (e.g., printf) contain functionality which is
- not wanted in embedded systems." 24 May 1999
-
-
-
-Q: So uClibc is smaller then glibc? Doesn't that mean it completely sucks?
- How could it be smaller and not suck?
-
- uClibc has been designed from the ground up to be a C library for embedded
- Linux. We don't need to worry about whether we support MS-DOS, or Cygwin,
- or any other system. This lets us cut out lots of complexity, and very
- carefully optimize for Linux. By very careful design, we can also make a
- few shotcuts. For example, glibc contains an implementation of the
- wordexp() function, in compliance with the Single Unix Specificaion,
- version 2. Well, standards are important. But so is pragmatism. The
- wordexp function adds almost 100k to glibc, and yet I am not aware of even
- one Linux application that uses wordexp. So uClibc doesn't have wordexp().
-
- Glibc is a general purpose C library, and so as policy things are optimized
- for speed. uClibc has a large number of routines that have been very
- carefuly written to optimize for size instead of speed.
-
- The end result is a C library that will compile just about everything you
- throw at it, thet looks like glibc to application programs when you
- compile, and is many times smaller.
-
-
-
-Q: Why should I use uClibc?
-
- I don't know if you should use uClibc or not. It depends on your goals.
- If you are building an embedded system, and you are tight on space, then
- using uClibc instead if glibc should allow you to use your storage for
- other things.
-
- If you are trying to build a ultra fast fileserver for your company that
- has 12 Terabytes of storage, then you probably want to use glibc...
-
-
-
-Q: I want to create a closed source commercial application and I want to
- protect my intellectual property. If I use uClibc, don't I have to
- release my source code?
-
- No, you do not need to give away your source code just because you use
- uClibc and/or run on Linux.
-
-
-
-Q: I want to create a closed source commercial application using uClibc.
- Is that legal?
-
- Yes. uClibc is licensed under the LGPL, just like GNU libc. If you are
- using uClibc as a shared library, then your closed source application is
- 100% legal. Please consider sharing some of the money you make. :-)
-
- If you are staticly linking your closed source commercial application with
- uClibc, then you must take additional steps to comply with the uClibc
- license. You can sell your application as usual, but you must also make
- your closed source application available to your customers as an object
- file which can then be linked with updated versions of uClibc. This will
- (in theory) allow your customers to later link with updated versions of
- uClibc. You do not need to make the application object file available to
- everyone, just to those you gave the fully linked application.
-
-
-
-Q: How do I compile stuff?
-
- The easiest way is to use the compiler wrapper built by uClibc. Instead of
- using your usual compiler or cross compiler, you can use i386-uclibc-gcc,
- (or whatever is appropriate for your architecture) and it will automagically
- make your program link against uClibc.
-
-
-
-Q: How do I make autoconf and automake behave?
-
- First run
- export PATH=/usr/i386-linux-uclibc/bin:$PATH
- (or similar adjusted for your target architecture) then run you can simply
- run autoconf/automake and it should _just work_.
-
-
-
-Q: When I run 'ldd' to get a list of the library dependancies for a uClibc
- binary, ldd segfault! Or it runs my application? Anyways, it doesn't
- work! What should I do?
-
- Use the ldd that is built by uClibc, not your system's one. When your
- system's ldd looks for the library dependancies, it actually tries to
- _execute_ that program. This works fine -- usually. I doesn't work at all
- when you are cross compiling (thats why ldd segfaults). The ldd program
- created by uClibc is cross platform and doesn't actually try to run the
- target program like your system one does, so it should do the right thing,
- and won't segfault, even when you are cross compiling.
-
-
-
-Q: I need you to add <favorite feature> now! How come you don't answer all my
- questions on the mailing list withing 5 minutes? I demand that you help me
- Right Now!
-
- You have not paid me a single cent and yet you still have the product of
- over year and a half of my work, and lots of work from other people. How
- dare you treat me that way! I work on uClibc because I find it
- interesting. If you go off flaming me, I will ignore you.
-
-
-
-Q: I need you to add <favorite feature>! Are the uClibc developers willing to
- be paid in order to add in <favorite feature>? Are you willing to provide
- support contracts?
-
- Sure! Now you have our attention! What you should do is contact
- Erik Andersen of CodePoet Consulting to bid on your project. If Erik
- is too busy to personally add your feature, there are several other
- active contributors who may be able to help you out.
-
-
-Q: I think you guys are great and I want to help support your work!

+</TD></TR>
+<TR><TD BGCOLOR="#eeeee0">
+
+ This history and origin of uClibc is long and twisty.
+ In the beginning, there was <a href="http://www.gnu.org/software/libc/libc.html">GNU libc</a>. Then, libc4
+ (which later became linux libc 5) forked from GNU libc version 1.07.4, with
+ additions from 4.4BSD, in order to support Linux. Later, the <a
+ href="http://www.cix.co.uk/~mayday/">Linux-8086 C library</a>, which is part of
+ the <a href="http://www.elks.ecs.soton.ac.uk/">elks project</a>, was created,
+ which was, apparently, largely written from scratch but also borrowed code from
+ libc4, glibc, some Atari library code, with bits and pieces from about 20 other
+ places. Then uClibc forked off from the Linux-8086 C library in order to run
+ on <a href="http://www.uclinux.org">µClinux</a>.
+ <p>
+
+ I had for some time been despairing over the state of C libraries in Linux.
+ GNU libc, the standard, is very poorly suited to embedded systems (and it just
+ gets bigger with every release). I spent quite a bit of time looking over the
+ other Open Source C libraries that I knew of (listed below), and none of them really
+ impressed me. I felt there was a real vacancy in the embedded Linux ecology.
+ The closest library to what I imagined an embedded C library should be was
+ uClibc. But that had a lot of problems too -- not the least of which was that,
+ traditionally, uClibc had a complete source tree fork in order to support each
+ and every new platform, resulting in a big mess of twisty versions, all
+ different. I decided to fix it and the result is what you see here.
+ My source tree has now become the official uClibc source tree and it now lives
+ on cvs.uclinux.org.
+
+ <p>
+
+ To start with, (with some initial help from <a
+ href="http://www.uclinux.org/developers/index.html">D. Jeff Dionne</a>), I
+ ported it to run on x86. I then grafted in the header files from glibc 2.1.3
+ and cleaned up the resulting breakage. This (plus some additional work) has
+ made it almost completely independant of kernel headers, a large departure from
+ its traditional tightly-coupled-to-the-kernel origins. I have written and/or
+ rewritten a number of things that were missing or broken, and sometimes grafted
+ in bits of code from the current glibc and libc5. I have also built a proper
+ platform abstraction layer, so now you can simply edit the file "Config" and
+ use that to decide which architecture you will be compiling for, and whether or
+ not your target has an MMU, and FPU, etc. I have also added a test suite,
+ which, though incomplete, is a good start. Several people have helped by
+ contributing ports to new architectures, and a lot of work has been done on
+ adding support for missing features.

+<a href="http://uclibc.org">uClibc</a> (aka µClibc but pronounced
+yew-see-lib-see) is a C library for embedded Linux systems. It is much smaller
+then GNU libc, but nearly all applications supported by the
+<a href="http://www.gnu.org/software/libc/libc.html">GNU C Library (aka glibc)</a>
+also work perfectly with uClibc. Porting applications from
+glibc to uClibc typically involves just recompiling the source code. uClibc
+supports standard Linux systems (such as x86, strongArm, and powerpc), and also
+supports <a href="http://www.uclinux.org">MMU-less (also known as µClinux)</a>
+systems, such as those based on the Coldfire, dragonball, or arm7tdmi
+micro-controllers. If you are building an embedded Linux system, and you fine
+the GNU libc is eating up too much space, you should consider using uClibc
+instead. If you are working on an older system with limited memory (such as an
+oldworld Mac), uClibc may also be useful for you. If you are using a standard
+desktop Linux workstation to develop applications for an embedded Linux system,
+you can use run uClibc on your workstation while doing development. If you are
+trying to build a ultra fast fileserver for your company that has 12 Terabytes
+of storage, then you probably want to use glibc...

-This history and origin of uClibc is long and twisty.
-In the beginning, there was <a
-href="http://www.gnu.org/software/libc/libc.html">GNU libc</a>. Then, libc4
-(which later became linux libc 5) forked from GNU libc version 1.07.4, with
-additions from 4.4BSD, in order to support Linux. Later, the <a
-href="http://www.cix.co.uk/~mayday/">Linux-8086 C library</a>, which is part of
-the <a href="http://www.elks.ecs.soton.ac.uk/">elks project</a>, was created,
-which was, apparently, largely written from scratch but also borrowed code from
-libc4, glibc, some Atari library code, with bits and pieces from about 20 other
-places. Then uClibc forked off from the Linux-8086 C library in order to run
-on <a href="http://www.uclinux.org">µClinux</a>.
-<p>
-
-I had for some time been despairing over the state of C libraries in Linux.
-GNU libc, the standard, is very poorly suited to embedded systems (and it just
-gets bigger with every release). I spent quite a bit of time looking over the
-other Open Source C libraries that I knew of (listed below), and none of them really
-impressed me. I felt there was a real vacancy in the embedded Linux ecology.
-The closest library to what I imagined an embedded C library should be was
-uClibc. But that had a lot of problems too -- not the least of which was that,
-traditionally, uClibc had a complete source tree fork in order to support each
-and every new platform, resulting in a big mess of twisty versions, all
-different. I decided to fix it and the result is what you see here.
-My source tree has now become the official uClibc source tree and it now lives
-on cvs.uclinux.org.
-
-<p>
-
-To start with, (with some initial help from <a
-href="http://www.uclinux.org/developers/index.html">D. Jeff Dionne</a>), I
-ported it to run on x86. I then grafted in the header files from glibc 2.1.3
-and cleaned up the resulting breakage. This (plus some additional work) has
-made it almost completely independant of kernel headers, a large departure from
-its traditional tightly-coupled-to-the-kernel origins. I have written and/or
-rewritten a number of things that were missing or broken, and sometimes grafted
-in bits of code from the current glibc and libc5. I have also built a proper
-platform abstraction layer, so now you can simply edit the file "Config" and
-use that to decide which architecture you will be compiling for, and whether or
-not your target has an MMU, and FPU, etc. I have also added a test suite,
-which, though incomplete, is a good start. Several people have helped by
-contributing ports to new architectures, and a lot of work has been done on
-adding support for missing features.
