...nstructions on the R Administration guide. The output can be seen at here (https://gist.github.com/nguyenvinh/504321ea9c89d8919bef) and yields no errors . However, I get a segfault whenever I try to use the install.packages function to install packages. Using debug, I was able to trace it to the readDCF function: Browse[2]> debug: if (!all) return(.Internal(readDCF(file, fields, keep.white))) Browse[2]> debug: return(.Internal(readDCF(file, fields, keep.white))) Browse[2]> *** caught segfault *** address 4, cause 'invalid permissions' Possible actions: 1: abort (with core dump...

Here's an update: I checked the ChangeLog for R, and it seems like readDCF was changed in 3.0.2. I went on a whim and copied src/main/dcf.c from R 2.15.3 over to 3.2.2, and R compiled fine and install.packages now work for me. This is probably not ideal, but it at least makes R usable on AIX for me. Would definitely like to help figure out what's wrong with the new...

Hi there, I just wanted to follow up on this readDCF issue with install.packages on AIX on R 3.*. I'm happy to help try potential solutions or debug if anyone could point me in the right direction. To re-cap, it appears readDCF is segfault'ing since R 3.* on AIX. This was not the case up until R 2.15.3. This makes install.packages not usab...

...rice of a slow down and increased memory usage for all DCF files. Sounds less than optimal :-/ Cheers, H.

...t; However, Herve's second example does illustrate a bug I can reproduce: > one character out of 10000 was read incorrectly. Could you please try > his final patch and see if it fixes your AIX problems? Just tried the latest dcf.c from R-dev and install.packages no longer segfaults from readDCF. Thank you both Duncan and Murdoch for your help. Can finally make use of this AIX box now (fyi placed request to get gdb installed but who knows when that would've been installed). Thanks again. -- Vinh
