Trying to build a G95 snapshot

[angelo.graziosi@…]

It seems that the development of G95 (​http://www.g95.org) is restarted so I have tried to build current snapshot (​http://ftp.g95.org/g95_source.tgz, 2012.12.19). I don't understand completely Portfile language but I have tried to follow this ​https://trac.macports.org/browser/trunk/dports/lang/g95/Portfile, and my steps have been:

wget ftp://gcc.gnu.org/pub/gcc/releases/gcc-4.2.4/gcc-core-4.2.4.tar.gz

tar -xvf gcc-core-4.2.4.tar.gz

cd gcc-4.2.4

patch gcc/gcc.c /opt/local//var/macports/sources/rsync.macports.org/release/tarballs/ports/lang/g95/files/patch-gcc.c.diff

mkdir g95

cd g95

CC=llvm-gcc-4.2 ../configure --enable-languages=c --with-included-gettext --with-as=/usr/bin/as --with-ld=/usr/bin/ld --with-nm=/usr/bin/nm --build=x86_64-apple-darwin11 --host=x86_64-apple-darwin11

make

but 'make' fails:

make[3]: *** [xgcc] Error 1
make[2]: *** [all-stage1-gcc] Error 2

Have you any ideas how to fix this?

TIA,

Angelo.

Oops... I have applied also this patch (for darwin.h), obviously,

cd gcc-4.2.4

patch gcc/gcc.c [...]

patch gcc/config/darwin.h /opt/local//var/macports/sources/rsync.macports.org/release/tarballs/ports/lang/g95/files/patch-darwin.h.diff

I updated g95 to v0.93. I have no intention to follow snapshots. They have binaries if you need to use the snapshot. There are a number of changes required in order to successfully build g95. The ticket is to report a bug in Portfile, not to support how to build manually. You could learn how to write Portfile to find what changes are needed. A Tcl extension reinplace is used to edit files. See ​MacPorts Guide and ​Tcl documentation. Alternatively, modify Portfile to use the snapshot. You probably need to edit master_sites and checksum fields. You could use a ​local port tree. Since g95 port is relatively complicated, I would rather use v0.93 or the binary from the developer.
