[Mark Brethen]

After reviewing: https://trac.macports.org/wiki/PortfileRecipes#compiler I 
tried:

compiler.blacklist  *clang* *llvm-gcc-4.2
compiler.whitelist  macports-gcc-4.9

pre-build {
build.args  CC=${configure.cc} \
CXX=${configure.cxx}
}

This builds with gcc 4.9 successfully.

Re: html and postscript viewer

It fails in a similar fashion, which is why I don’t think my first attempt 
actually used gcc 4.9. What are the commands to set a default compiler?

You should remove -L/usr/X11R6/lib; we don't want to get any libraries from 
there. We want to use the versions installed in ${prefix} by MacPorts. 

You should replace "g++" not with "$(CC)" but with "$(CXX)".

You are technically correct, but I suspect your use case is going to be 
applicable only for a small group of users who are also developers.


/usr/bin/open is the command-line interface to the LaunchServices API, 
which is supposed to handle all this. I am not aware of any clean way to 
query Safari's preferences to determine the default browser without 
groveling through plist files, or perhaps AppleScript.


(Looking on the web, I see your openbrowser script does exactly 
that--grinds through plist files via Perl--but that introduces an 
additional dependency. I'd suggest that using a system-bundled tool is 
almost always better. It's certainly simpler.)

Re: html and postscript viewer

[Mark Brethen]

According to the documentation these parameters are actually the names of shell 
scripts that CGX runs to open the viewers. For example, the instruction for the 
html viewer are as follows:

Create the shell script, respectively a file with filename “firefox“ (or any 
other file- name) in a directory of your choice: “dir_your_choice“ (for example 
your HOME: /Users/LOGNAME) by using an editor of your choice. Next, insert the 
following two

lines in file: “firefox“, then safe and quit the file: 

#!/bin/bash
open -a Firefox $1

The above shell script “firefox” enables to launch Firefox from a Terminal 
window with command: $ firefox  . In the second line of the 
above script: "open" opens application (-a) Firefox, input is passed via “$1”.

It applies to any user who has changed the file association for .html files. 
There's no reason to inconvenience that subset of users when a solution exists.

/usr/bin/open is not necessarily suitable. For example, I have configure my 
system so that if I `open` a .html file, it opens into my text editor, because 
I frequently edit html files. However, if another program is trying to open a 
web page, then I want that web page to open in my web browser, not my text 
editor.

My openbrowser program solves this problem by opening the given file in the 
system configured web browser, not the program associated with .html files.

Re: html and postscript viewer

[Mark Brethen]

A header file specifies these parameters:


/* html browser, change if necessary */
/* postscript viewer, change if necessary */
#ifdef MTU
  #define BROWSER {"firefox"}
  #define PSVIEWER {"gv"}
#else
/* #define BROWSER {"netscape"} */
/*   #define BROWSER {"mozilla"} */
  #define BROWSER {"firefox"}
/* #define PSVIEWER {"ghostview"} */
  #define PSVIEWER {"gv”}
#endif


And also the location of the help files:

/* default location of the help files, please insert the actual one */
#ifdef MTU
  #ifdef DEVEL
#define HELPFILE{"/yaprod/yae55/Linux_x86_64/bin/cgx_doc/cgx.h$
 "/yaprod/yae55/Linux_x86_64/bin/ccx_doc/ccx.html"}
  #else
#define HELPFILE{"/yaprod/cae/application/CalculiX/doc/cgx_2.1$
 "/yaprod/cae/application/CalculiX/doc/ccx_2.10/cc$
  #endif
#elif defined AFLIB
  #define HELPFILE{"/usr/local/CalculiX/cgx_2.10/doc/cgx/cgx.html"$
"/usr/local/CalculiX/ccx_2.10/doc/ccx/ccx.html",\
"/usr/local/CalculiX/cgx_2.10/doc/aflib/aflib.pdf"}
#else
  #define HELPFILE{"/usr/local/CalculiX/cgx_2.10/doc/cgx/cgx.html"$
"/usr/local/CalculiX/ccx_2.10/doc/ccx/ccx.html"}
#endif

I’ll use /opt/local/share/doc/${name} for the default location.

For mac users, they recommend changing ‘gv’ to ‘preview’ but give no 
recommendation for a browser. I thought I’d ask here whether to keep it firefox 
or change it to something else? Safari?

/usr/bin/open will launch the user-defined default browser and image 
viewer for the system, with no further configuration on the developer's 
part required.

OS X lets the user specify their preferred browser. This setting can be changed 
in Safari's preferences window. You should respect that preference.

How does Culculix CGX invoke the web browser? If it does so by running a 
command (such as "firefox" on other platforms), then you can use my openbrowser 
port and the openbrowser command it provides to accomplish that.

If they run a command to invoke a the PostScript viewer, then you would 
probably use "open -a Preview.app" to open Preview.
