From: Mark Hull-Richter Subject: Problems with (first compile under) djgpp/gcc To: djgpp AT sun DOT soe DOT clarkson DOT edu Date: Tue, 7 Feb 1995 08:49:17 -0800 (PST) I have a program of some 7000 lines that I have successfully compiled and run on four Unix platforms and would like to have run on my PC. I gave up on Turbo C and Borland C++ because they gave me just too many problems that did not seem to be related to the code itself (minor things like different include paths, sizeof(char) == 0, j += k fails, etc). So I turnedto djgpp. However, although all nine files compile ok, the link at the end (final gcc call) fails because of a series of errors that look like this: lh-dice.c(.text+0x12c): undefined reference to `srand48' lh-dice.c(.text+0x141): undefined reference to `lrand48' lh-dice.c(.text+0x18f): undefined reference to `lrand48' lh-dice.c(.text+0x23a): undefined reference to `lrand48' lh-dice.c(.text+0x24e): undefined reference to `lrand48' lh-dice.c(.text+0x2bf): undefined reference to `lrand48' lh-dice.c(.text+0x329): more undefined references to `lrand48' follow make.exe: *** [lh] Error 1 lh-dice.c is a generic "dice roller" module that uses srand48 to initialize the random number generator and lrand48 to generate the random numbers it turns into dice rolls. It includes up front, and in looking through the supplied (djgpp) stdlib.h, I find it includes djgppstd.h, which contains the indicated function declarations. What's wrong? I have djgpp installed on my f: drive under f:\gcc. My path includes f:\gcc\bin (at the end) and I run `f:\gcc\bin\setdjgpp f:\gcc f:/gcc' as a prelude to running `make' on the makefile. The only difference between the PC makefile and my unix makefile is that the target `lh' has the "-o lh" before the modules list instead of after it. There are no other "make.exe" files in the path before the gcc make. -- ++== AT&T Mark A.
