Attached is a patch to fix the compilation errors in fsvs. I built using gcc 4.6, since that's what I have by default.
There are a couple problems that I want to point out. The size of an integer constant expression (which is what must be used as array sizes), shall have, according to N1124, integer type and shall only have operands that are integer constants, enumeration constants, character constants, sizeof expressions whose results are integer constants, and floating constants that are the immediate operands of casts. Cast operators in an integer constant expression shall only convert arithmetic types to integer types, except as part of an operand to the sizeof operator. You are not allowed to call functions or use floating point math, ever. So instead of "*3.32," I used "*332/100". Also, you can't initialize variable-length arrays, so I used a workaround for those two cases involving preprocessor constants. You may choose to adopt a different solution. Linking requires -laprutil-1, but that isn't provided at the moment, so the package will still FTBFS with my patch. Also, you'll need some version of libdb-dev because otherwise db.h isn't provided and the package fails very early. I used libdb4.8-dev since that's what APR uses. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
