misc/tools/README.txt ===================== 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 This is a snapshot of the kconfig-frontends version 3.6.0 tarball taken from http://ymorin.is-a-geek.org/projects/kconfig-frontends. General build instructions: cd kconfig-frontends ./configure make make install To suppress the graphical interfaces: ./configure --disable-gconf --disable-qconf make make install kconfig-frontends-3.3.0-1-libintl.patch The above build instructions did not work for me under my Cygwin installation with kconfig-frontends-4.4.0. This patch is a awful hack but will successfully build '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: According to the release notes, version 3.6.0 (and above) will build on Cygwin with no patches: http://ymorin.is-a-geek.org/download/kconfig-frontends/ kconfig-macos.path This is a patch to make the kconfig-frontends-3.3.0 build on Mac OS X.
