I've recently installed gcc 4.2.1 on i686-pc-cygwin from source code. I've
been testing the gfortran compiler and ran across a problem linking f77
libraries. My Makefile is:
mingwlib = -L/cygdrive/c/Devel/MinGW/lib
CFLAGS = -O2 -malign-double -mtune=pentium4
You may want to remove this option (unless you
compiled libgfortran.a with it).
This produces many errors similar to:
/cygdrive/c/Devel/MinGW/lib/libSLATEC.a(xersve.o):xersve.f:(.text+0x206):
undefined reference to `_s_copy'
The program compiles using g77 without problems. I'd like to know if it is
possible to use the SLATEC and PSPLOT as-is or do I need to recompile new
libraries to use in gfortran. (For the moment, I'd like to link to these
existing libraries if possible.) I've tried various gfortran switches and
macros but to no avail.
You'll probably need to use the -ff2c option and add -lg2c to
your library list.
Recompiling SLATEC and PSPLOT with gfortran would make your life
easier in the long run.
