phosphorescence: F# 3.0 on Mono 3.0 on FreeBSD

Tuesday, January 15, 2013

(continued from phosphorescence: Mono 3.0.x is also ready for FreeBSD)

When we want to use F# on Mono 3.0 on FreeBSD, we should build from source file, not from ports' fsharp.

How

$ git clone https://github.com/fsharp/fsharp.git
$ cd fsharp
$ vi configure.ac

In configure.ac, update around sgen options as acomments. Reasons later.

#if test "x$MONO_SGEN" = "xno"; then
# mono_gc_options=
#else
# mono_gc_options=--gc=sgen
#fi

And then,

$ ./autogen.sh --with-gacdir=/usr/local/lib/mono/gac
$ gmake
$ sudo gmake install

Let's launch F# REPL.

$ fsharpi

The reason is the status of LLVM support for Mono on FreeBSD.

mono-sgen - The FreeBSD Forums

Mono LLVM option for FreeBSD is not stable.
For Mono on POSIX, pthread is the only thread mechanism until LLVM (supporting "__thread") will support mono on FreeBSD stably.
On FreeBSD, so that we can use pthread without sgen, and also can use sgen without pthread.

Unknown said...: It would be helpful to state, where to place the tree obtained from GIT so the build works.
I just got it to my /opt/lib/fsharp location and there, the build does not seem to work. I find fsi.exe and fsc.exe etc. only in fsharp/lib/bootstrap/4.0 but nowhere else.
Also there is no /usr/local/lib/mono/gac after my installation.; Thursday, March 21, 2013 at 5:05:00 PM GMT+9

We may wait a few weeks, so we will use fsharp on sgen as out-of-the-box.; Thursday, March 21, 2013 at 9:00:00 PM GMT+9
