Install Notes: This program has been compiled on the following UNIX systems: Sun/OS 4.1.x Sun/OS 5.1 (Solaris 2.1) ULTRIX 4.2 ULTRIX 4.3 OSF 3.0 IRIX 4.0.1 IRIX 4.0.5F HP-UX 7.00 HP-UX 8.07 HP-UX 9.01 AT&T System V.3.2 BSD 4.3 Linux (by upsyf173@HRZ.Uni-Bielefeld.DE) FreeBSD AIX 3.2.4 NeXTStep (by mgrlhc@NeXTwork.Rose-Hulman.Edu) System V/88 (by tony@plaza.ds.adp.com) MP-RAS 2.0 (by Shawn.Shealy@ColumbiaSC.NCR.COM) Coherent 4.2.x (by fredex@fcshome.stoneham.ma.us) If splitvt fails to run and prints out the message: "Can't initialize screen: Your terminal lacks the XX termcap capability." then do "make clean", remove "-DTERMCAP" from the CFLAGS line in the Makefile and then recompile. Under AT&T System V.3.2 (a 3b2 machine) I had to add the line: CC = gcc at the top of the Makefile so that it didn't get a syntax error in /usr/include/sys/wait.h. This particular 3b2 machine had been souped up with gcc and other exotic software. Under Sun/OS 5.0 (Solaris 2.1), running gcc, the grantpt() function breaks under the -O compiling option. Just remove that from the CFLAGS, and everything will work fine.
