[fpc-pascal] Cross compiling from win32 to linux
I try to crosscompile in win32 to linux with fpc 2.1.1. I use the options: -Sd -B -Tlinux The compiler compiles all the sources without problem, but the linker reports an errror: unrecognised emulation mode: elf_i386 this is because fpc calls ld instead of i386-linux-ld when i rename i386-linux-ld to ld, the linker reports another error: cannot find -lpthread where is my fault ? thanks, Adrian Veith. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

It seems really weird that there is no such unit in the standard freepascal distribution. It would be a huge task for me to create one with C-like speed.

Use -XPi386-linux- to let fpc use i386-linux-ld for the linking. You also need to have a copy of all .so files needed for the linking.

Is it backwards compatibility? FPC is IEEE-spec compliant, since all computer follow up floating point standard. It should follow up to 80 bits for double-extended precision. Note that IEEE specification is recently under revision. > It seems really weird that there is no such unit in the standard > freepascal distribution.

If I understand it correctly, you're looking for sources for old FPC versions (especially for the compiler). You can find sources for all released versions starting with 1.0.0 under ftp://ftp.freepascal.org/pub/fpc/olddist/, and in addition to this, one of the early alpha versions can be found in ftp://ftp.freepascal.org/pub/fpc/attic/.

[fpc-pascal] Division by Zero - not raised exception
FPC 2.0.2 do not rasie exception on integer/floats division by Zero, which is suitable for calucaltion I currently developing. Instead, division return infinity: writeln(1/0) -> +inf writeln(1.0/0) -> +inf With excluding zero exception from SetExceptionMask(), it dows not turn on the exception (unless there is another way). In any event, division by zero should raise exception by default. Perhaps it is solved in some latest release?
