These are not of general use as they are tied to my personal development environment. The concepts may be useful to others, however, who may want to adapt this logic for their own purposes. genromfs-0.5.2.tar.gz ===================== This is a snapshot of the genromfs tarball taken from http://sourceforge.net/projects/romfs/. This snapshot is provided to assure that a working version of genromfs is always available for NuttX. This tool is also include in the buildroot and can be built automatically from the buildroot. kconfig-frontends ================= General Build Instructions -------------------------- This is a snapshot of the kconfig-frontends version 22.214.171.124 tarball taken from http://ymorin.is-a-geek.org/projects/kconfig-frontends. General build instructions: cd kconfig-frontends ./configure --enable-mconf make make install It is a good idea to add '--enable-mconf' on the 'configure' command line. The kconfig-frontends make will generate many programs, but the NuttX build system only needs the 'kconfig-conf' and 'kconfig-mconf' programs. If the requirements for 'kconfig-mconf' are not supported by your system, the kconfig-frontends configuration system will not build it. Adding the option --enable-mconf assures you that 'kconfig-mconf' will be built or if it is not built, it will tell you why it was not built. To suppress the 'nconf' and the graphical front-ends which are not used by NuttX, you can add: ./configure --enable-mconf --disable-nconf --disable-gconf --disable-qconf make make install To suppress the graphical interfaces, use static libraries, and disable creation of other utilities: ./configure --disable-shared --enable-static --enable-mconf --disable-nconf --disable-gconf --disable-qconf --disable-nconf --disable-utils make make install The default installation location for the tools is /usr/local/bin. You may require root privileges to 'make install'. Graphical Configuration Tools ----------------------------- If you have an environment that suppots the Qt or GTK graphical systems (probably KDE or gnome, respectively), then you can also build the graphical kconfig-frontends, kconfig-qconf and kconfig-gconf: ./configure --enable-mconf --disable-nconf --disable-gconf --enable-qconf make make install Or, ./configure --enable-mconf --disable-nconf --enable-gconf --disable-qconf make make install In these case, you can start the graphical configurator in the nuttx/ directory with either: make qconfig or make gconfig --program-prefix= ----------------- Beginning somwhere between version 3.3.0 and 3.6.0, the prefix was added to the kconfig-frontends tools. The default prefix is kconfig-. So, after 3.3.0, conf becomes kconfig-conf, mconf becomes kconfig-mconf, etc. All of the NuttX documentation, Makefiles, scripts have been updated to used this default prefix. This introduces an incompatibility with the 3.3.0 version. In the 3.6.0 timeframe, the configure argument --program-prefix= was added to eliminated the kconfig- prefix. This, however, caused problems when we got to the 3.7.0 version which generates a binary called kconfig-diff (installed at /usr/local/bin). Without the prefix, may conflict with the standard diff utility (at /bin), depending upon how your PATH variable is configured. Because of this, we decided to "bite the bullet" and use the standard prefix at 3.7.0 and later. This problem could probably also be avoided using --disable-utils. kconfig-frontends-3.3.0-1-libintl.patch --------------------------------------- The above build instructions did not work for me under my Cygwin installation with kconfig-frontends-3.3.0. This patch is a awful hack but will successfully build 'kconfig-mconf' under Cygwin. cat kconfig-frontends-3.3.0-1-libintl.patch | patch -p0 cd kconfig-frontends-3.3.0-1 ./configure --disable-gconf --disable-qconf make make install See: http://ymorin.is-a-geek.org/hg/kconfig-frontends/file/tip/docs/known-issues.txt Update: Version 3.6.0 (and above) will build on Cygwin with no patches: http://ymorin.is-a-geek.org/download/kconfig-frontends/ kconfig-macos.patch ------------------- This is a patch to make the kconfig-frontends-3.3.0 build on Mac OS X. To build the conf and mconf frontends, use the following commands: ./configure --disable-shared --enable-static --disable-gconf --disable-qconf --disable-nconf --disable-utils make make install kconfig-mconf Path Issues ------------------------- Some people have experienced this problem after successfully building and installing the kconfig-frontends tools: kconfig-mconf: error while loading shared libraries: libkconfig-parser-3.8.0.so: cannot open shared object file: No such file or directory make: *** [menuconfig] Error 127 There two known solutions to this: 1) Add the directory where the kconfig-frontends libraries were installed to the file /etc//ld.so.conf (probably /usr/local/lib), then run the ldconfig tool. 2) Specify the LD_RUN_PATH environment when building the kconfig-frontends tools like: ./configure --enable-mconf LD_RUN_PATH=/usr/local/lib make make install 3) Build the kconfig-frontends tools using only static libraries: ./configure --enable-mconf --disable-shared --enable-static I have also been told that some people see this error until they re-boot, then it just goes away. I would try that before anything else. gperf ----- "I am getting an error when configuring the kconfig-frontends-126.96.36.199 package. Using command ./configure --enable-mconf "It says it 'configure: error: can not find gperf'" If you see this, make sure that the gperf package is installed. gperf 3.1 and above ------------------- Version 3.12.0 of kconfig-frontends did not not build with gperf (version 3.1 released 2017-01-05). A files suggested by Harald Gutsche (Bitbucket Issue #1) is: I changed the type in line 12 to size_t: static const struct kconf_id *kconf_id_lookup(register const char *str, register size_t len); Philiipp Krause also notes that current 188.8.131.52 release also has issues, but can be fixed with a change to just one line (also Bitbucket Issue #1)): Change line 175 of hconf.c from kconf_id_lookup (register const char *str, register unsigned int len) to kconf_id_lookup (register const char *str, register GPERF_LEN_TYPE len) With this change, upstream should build fine both with gperf 3.1 and older versions. NOTE: This change has already been applied in the code base. See kconfig-frontends-3.12.0-sizet.patch for the 3.12.0 version. (from https://gist.github.com/KamilSzczygiel/d16a5d88075939578f7bd8fadd0907aa) kconfig-frontends for Windows ----------------------------- Recent versions of NuttX support building NuttX from a native Windows console window (see "Native Windows Build" below). But kconfig-frontends is a Linux tool. At one time this was a problem for Windows users, but now there is a specially modified version of the kconfig-frontends tools that can be used: http://uvc.de/posts/linux-kernel-configuration-tool-mconf-under-windows.html [The remainder of the text in this section is for historical interest only] From https://groups.yahoo.com/neo/groups/nuttx/conversations/messages/2900: "The build was quite simple: I used mingw installer and I had to install two packages that the automated mingw setup does not bring by default: * mingw-get update * mingw-get install mingw32-pdcurses mingw32-libpdcurses * mingw-get install msys-regex msys-libregex (grep the output of mingw-get list if I got the names wrong) Then I had to change some things in mconf code, it was quite simple to understand the make errors. * The first of them is to disable any use of uname() in symbol.c and replace the uname output by a constant string value (I used MINGW32-MSYS), * The second one is related to the second parameter to mkdir() that has to disappear for windows (we don't care about folder rights) in confdata.c; * And the last one of them involves #undef bool in dialog.h before including curses.h (CURSES_LOC), around line 30. I wrapped all of my changes in #if(n)def __MINGW32__, but that is not sufficient to make that work everywhere, I think. So mconf itself has some portability issues that shall be managed in a cleaner way, what I did was just hacks, I don't think they are acceptable by mconf upstream maintainers. Here is the magic incantation to get the whole thing working. It seems that the configure script is not so good and does not bring the required bits to link libregex. CFLAGS="-I/mingw/include -I/usr/include" LDFLAGS="-Bstatic -L/mingw/lib -L/usr/lib -lregex" ./configure --enable-frontends=mconf --enable-static --disable-shared So the message I want to pass is that native "make menuconfig" in windows IS POSSIBLE, I have done it in a few minutes." "Oops, forgot something, I had to bring a gperf binary from the gnuwin32 project." - Sebastien Lorquet Buildroot --------- As of 2014-3-7, the kconfig-frontends tools have been included in the buildroot tool set. This means that in one package you can build GCC tools that are especially tuned for NuttX and all of the support tools that you need ROMFS, configuration, and NXFLAT. nxfuse ====== A Linux FUSE implmentation that enables native mounting of NuttX filesystems in Linux. Currently supports SmartFS and NXFFS (within the limitations of the NXFFS architecture). See the nxfuse/README.txt file for further information.
