Compaq (DEC) Alpha chip cpu + Linux operating system are now spported in two ways. 1) If you have True64 unix (digital unix), it is recomended to complile the library and executables there. The executables can run on Alpha Linux, provided that you have to rebuild the kernel of the Alpha Linux to include the ECOFF support. How to do it will be found on the Web faq. For example, http://www.v-t.co.jp/support/faq/data/linux/linux00032.html. In Cosmos, You have to use site.configTrue64ForAlphaLinux as the site.config. The executable can run on both True64 and Alpha Linux 2) If you have no True64 unix system, you have to down load compaq Fortran from, http://www.digital.com/fortran/linux/te-download.html In this case, you have to use site.configCF_AlphaLinux as the site.config in Cosmos. Note: The comilation speed is very slow. /lib/cpp says that the odd number of ' or " in any one line is error. So we disregarded such errors issued form cpp. However, odd number of " is sometimes hurmful for complilation. You should not use it even in comment.
