Trying Erlang

Posted by Keith under Development Tools, Erlang, Unix/Linux

I tested DB and Yaws a bit, and found DB access wasn’t working for Solaris version of Erlang.  After some digging, I found that iodbc does not work.  There are two (open source) flavors for ODBC in Unix.  iodbc and unixODBC.  I recompiled Erlang with unixODBC, and DB access works — sort of.  Still some SQL doesn’t work properly, and I haven’t figured it out yet.  But it’s good enough to test Erlang and Yaws for now.  For Ubuntu, no problem.  Installing Erlang, ODBC, and Yaws were effortless.  But I like Sparc Solaris I use at home. :-)  It’s quite old, but still have enough disk space, RAM and works extremely well.

One thing about Yaws on Solaris — while I was building Yaws, I got an error from ‘id’ with option ‘-u’.  This is due to Solaris 9’s ‘id’ (located in /usr/bin) doesn’t support -u option.  I temporarily changed GNU’s ‘gid’ to ‘id’ and it built correctly.

vim, emacs, eclipse, NetBeans for Erlang

Posted by Keith under Erlang

I prefer to use GUI IDE such as eclipse and NetBeans, but I do have to work on terminals often.

Here is vim-erlang file: http://www.vim.org/scripts/script.php?script_id=1584

For emacs, read these pages:

And here is GUI IDE plug-ins,

NetBeans: http://sourceforge.net/projects/erlybird

PODS (Palm OS Development Suite) does not work on Vista

Posted by Keith under Development Tools, PDA

Tried everything.  I’ve gotten to the point where I can compile and get .prc file, but it just doesn’t work with IDE’s debugger, nor it launches the compiled PRC file to the simulator or emulator.

IT ONLY WORKS ON XP.

Of course, you can just drop the compiled .prc file onto the emulator/simulator and use the stand alone debugger it comes with.  But it is two extra steps — if you have a copy of XP, then it’s better to use VMWare or VirtualPC + WinXP.

I’ll post more info later.

…but it’s better to write apps for Android anyway…IMHO.
