A couple years ago, I successfully installed GHDL on Mac OS X (10.5.1) with
much help from Tristan. Below are my notes. Trying to reinstall on OS X 10.6.6
with the current version of GHDL I have no such success. It appears that the
GHDL package has changed substantially in the interim, so some of my notes are
no longer even applicable.
Anyone have any luck on OS X recently? Can anyone point me to some install
instructions that might get me back on track here?
I've also attached the ghdl.diff patch file below, which I think Tristan
created for me and got me going last time. Of course, this patch appears to
reference files that have moved.
Any help would be very much appreciated.
Best,
Jake
--------
Installing GHDL on Mac OS X (10.5.1)
--------
Install gnat using the gcc-4.3 package downloaded from www.macada.org.
Add gnat to the search path by adding the following line to the ~/.profile file:
export PATH="$PATH:/usr/local/ada-4.3/bin"
Create a directory called GHDL in the /Applications directory and change to
this directory.
Anonymously checkout the GHDL source with Subversion using the following
command (this should create a directory called /Applications/GHDL/trunk):
svn co svn://svn.gna.org/svn/ghdl/trunk ghdl
In the trunk/ortho/mcode/ortho_code-x86-flags.ads file, change 2 ** 3 to 2 ** 4
in the following line:
Stack_Boundary : Unsigned_32 := 2 ** 3
Copy the ghdl.diff patch to the trunk/ directory and from this directory run
the following command:
patch < ghdl.diff
In the trunk/translate/ghdldrv directory, run the following Make commands:
make target=x86-darwin
make target=x86-darwin install.mcode
In the trunk/translate/ghdldrv directory, create a symlink to the binary using
the following command:
ln -s ghdl_mcode ghdl
Add GHDL to the path by adding the following line to the ~/.profile file:
export PATH="$PATH:/Applications/GHDL/trunk/translate/ghdldrv/""
Open a new terminal window and run the following command to verify that GHDL
compiled and is setup appropriately:
ghdl -v
