Hi, I just successfully patched the openwrt-xburst to allow compilation of Fortran programs. The short patch is attached, and I'm ready to commit in case nobody objects.
To test the gfortran-enabled openwrt you need the following steps (after applying the patch): - make distclean - copy a new config to .config - enable the gfortan compiler via 'make menuconfig', deeply hidden in the the "advanced configuration options" menu - enable buildding of the the libgfortran run-time lib, in the "base system" menu (alternatively add these lines to your .config: CONFIG_INSTALL_GFORTRAN=y CONFIG_PACKAGE_libgfortran=y ) - install the libgfortran ipk on your nanonote Pre-build libgfortran ipk package available here: http://mosquito.dyndns.tv/~spock/openwrt/ For now I managed to compile and run a simple fortran90 hello world program: --8<-- program HelloWorld write (*,*) 'Hello, world!' ! This is an inline comment end program HelloWorld --8<-- via: mipsel-openwrt-linux-gfortran hello.f90 -o hello Did I overlook something? Is it just that simple? Never programmed in fortran. Next thing would be trying to port octave (probably using plplot as plotting backend?). cheers, David -- GnuPG public key: http://user.cs.tu-berlin.de/~dvdkhlng/dk.gpg Fingerprint: B17A DC95 D293 657B 4205 D016 7DEF 5323 C174 7D40
