First, fetch libutf-2.0 and libfmt-2.0 +from + http://pdos.lcs.mit.edu/~rsc/software/ + +(Beware that in libfmt/fmt.c there is a line that says: + 'u', __ifmt, /* in Plan 9, __flagfmt */ +Thus, sam will have to fmtinstall the other thing. Other ported programs +may have to do the same. The fmt library should probably print messages +about bad format characters to stderr, since no one seems to check the +return codes.) + +Compile and install those two libraries. +Set PREFIX in the Makefile to match, then compile sam. + +Your C compiler will emit many complaints of the form: + sam.c:496: warning: passing arg 1 of `bufread' from incompatible pointer type + +This is because the Plan 9 compiler has a slightly different (better, +ala Oberon) type system than ISO C. Popular compilers generate the right +code, so in an act of civil disobediance I changed just enough to get +it to compile, but left the type errors in. Now the next C standard can +adopt this extension, because at least one important C program uses it! + +-- Scott Schwartz, 4 July 2003 + |
