Linking program with libraries

Leif Halvarsson_2 — Wed, 13 Nov 2002 11:58:30 GMT

I get a list of 14 unsatisfied externals when I try to link a program with two subroutine-libraries. If I, as a test, omit the libraries the list will be about 75 unsatisfied externals.
It seems (to me) that the linker manages to find some subroutines but not all. The missing subroutines are referenced from either the main program or one of the libraries.
The program and the library subroutines are written in Fortran77 or C.

Compiling of library subroutine:
f90 -c -O -K -DAportable +U77 +ppu -o abbcor.o abbcor.F
cc -c -O -DAportable -Aa -D_HPUX_SOURCE -D_NO_PROTO -DSYSV -I/usr/include/X11R5 -o tsdrve.o tsdrve.c

Making the libraries:
ar rv libjack.a abbcor.o
ar rv c08.a tsdrve.o
ranlib libjack.a

Linking program:
f90 -Wl,-aarchive_shared -L/usr/lib/X11R5 -lm -O -o jackal jackal.o libjack.a c08.a

why not 'ranlib c08.a' ?

Hmm, shared archives requested, static archives made ...

f90 -c -O .... +Z blah.F
cc -c -O .... +Z -o foo.c
ld -b -o blah.sl blah.o
ld -b -o foo.sl foo.o

f90 -L. -L/usr/... -o jackal jackal.o -lblah -lfoo

Last had -o too many, soory ...

f90 -c -O .... +Z blah.F
cc -c -O .... +Z foo.c
ld -b -o blah.sl blah.o
ld -b -o foo.sl foo.o

f90 -L. -L/usr/... -o jackal jackal.o -lblah -lfoo

Hi!
Thank you procura for the answer!
There still is something wrong, however...
I have recompiled all routines in both libraries with the +Z option both for f90 and cc compilers and I have changed the extension for the libraries to .sl (instead of .a) and I use "ld -b -o" (instead of "ar rv") to enter the subroutines into the libraries, but now no library subroutine at all is loaded in the program, at least there is a very long list of unsatisfied externals.
I have tried to load the program with f90 or aCC (even if there are no C++ routines in this program) with the same result.
