Colleagues,
I have a large block (26K lines) of R code embedded in a GUI (built in
RealBasic). The code runs fine in OS X (Leopard / Snow Leopard / Lion) and
Windows but a user encountered a problem with Mountain Lion (I have not
upgraded any of my machines to Mountain Lion yet). The code appears to run
fine, then aborts near the completion of execution. The R code is written as a
series of functions, the final line of code calling those functions. So, I
know that the code has been read in its entirety. The problem occurs with R
2.15.1. The machine in question has Xcode 4.4.1 and the latest version of
Command Line Tools.
The GUI works by opening a shell, then sending the code to the shell a line at
a time. When the code aborts, the message:
dyld: DYLD_ environment variables being ignored because main executable
(/bin/ps) is setuid or setgid
appears in a console window. I have not seen this message before and I don't
know if it is the source of the problem. There are no error messages from R
(which there typically would be if there were a problem in the R code).
Instead, the GUI moves to the next step (opening a new shell and executing a
new set of R code).
Previously, I encountered a problem in which the quantity of R code overwhelmed
the shell (this was a bug in RealBasic). But, I don't think that this is the
problem here since the entirety of code has been read and execution is nearly
complete.
I don't know if this is a problem with R or something inherent to Mountain Lion
or some bizarre interaction between them (or with Xcode). If anyone has any
thoughts on this, I would be most appreciative.
