Hi: I tried to install the latest version of R (2-1.0)in an AIX machine . I was able to tar, and configure with no errors. However, when I said make, I got the following errors: gcc -Wl,-bM:SRE -Wl,-H512 -Wl,-T512 -Wl,-bnoentry -Wl,-bexpall -Wl,-bI:../../../etc/R.exp -L/usr/local/lib -o R_X11.so dataentry.lo devX11.lo rotated.lo rbitmap.lo -lSM -lICE -lX11 ld: 0711-317 ERROR: Undefined symbol: .log10 ld: 0711-317 ERROR: Undefined symbol: .floor ld: 0711-317 ERROR: Undefined symbol: .libintl_gettext ld: 0711-317 ERROR: Undefined symbol: .pow ld: 0711-317 ERROR: Undefined symbol: .sin ld: 0711-317 ERROR: Undefined symbol: .cos ld: 0711-317 ERROR: Undefined symbol: .tan ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. collect2: ld returned 8 exit status make: 1254-004 The error code from the last command is 1. Stop. make: 1254-004 The error code from the last command is 2. I understand I have to edit the Makefile. Can someone please tell me which Makefile (folder?) and which flags? I greatly appreciate your help. Thanks. Ambika Sundaresan Graduate Student UCSD
