error make g77

[marlh]

Dear all !
when i make file, report of fedora:

gcc sorter_GR.o sorter_util.o sorter_init.o sorter_hb.o sorter_user.o sorter_read.o -lgfortran /usr/lib/cernlib/2006-g77/lib/libpacklib.so.1.2006 /usr/lib/cernlib/2006-g77/lib/libkernlib.so.1.2006 /usr/lib/cernlib/2006-g77/lib/libmathlib.so.2.2006 -lnsl -lcrypt -ldl -o sorter_GR
/usr/bin/ld: sorter_user.o: undefined reference to symbol 'atan@@GLIBC_2.0'
/usr/bin/ld: note: 'atan@@GLIBC_2.0' is defined in DSO /lib/libm.so.6 so try adding it to the linker command line
/lib/libm.so.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make: *** [sorter_GR] Error 1

I don't know why? I installed all packlib for g77. Can you help me, how to solve it?

add -lm to the linker command, without the source code this is all the help I can offer.

Post the following diagnostic info too

uname -rm
POSIXLY_CORRECT=foo file /lib/libm.so.6
file sorter_GR.o

I try but still incorrect. This is my make file:

CC = g77
CFLAGS = -O2
CERNFLAGS = -Df2cFortran -I/usr/bin/cfortran

mathlib = -lm
cernlib = /usr/lib/cernlib/2006-g77/lib/libpacklib.so.1.2006 /usr/lib/cernlib/2006-g77/lib/libkernlib.so.1.2006 /usr/lib/cernlib/2006-g77/lib/libmathlib.so.2.2006 -lnsl -lcrypt -ldl


LIBRARIES = ${mathlib}

#----- LINK ---->
sorter_GR : sorter_GR.o sorter_util.o sorter_init.o sorter_hb.o sorter_user.o sorter_read.o
gcc sorter_GR.o sorter_util.o sorter_init.o sorter_hb.o sorter_user.o sorter_read.o -lgfortran $(cernlib) -o sorter_GR
# g77 sorter_GR.o sorter_util.o sorter_init.o sorter_hb.o sorter_user.o sorter_read.o $(cernlib) -o sorter_GR
# g77 sorter_GR.o sorter_util.o sorter_init.o sorter_hb.o sorter_user.o sorter_read.o `cernlib packlib, mathlib` -o sorter_GR
# $(CC) sorter_GR.o sorter_util.o sorter_init.o sorter_hb.o sorter_user.o sorter_read.o `cernlib packlib, mathlib` -o sorter_GR

#----- OBJECTS ---->

#----- CLEANING ---->
clean:
rm -f *.o core.*

what's wrong?

i don't understand ? could you tell it more?

[leigh123linux]

I think add -lm to this line should fix it

change this

cernlib =  /usr/lib/cernlib/2006-g77/lib/libpacklib.so.1.2006  /usr/lib/cernlib/2006-g77/lib/libkernlib.so.1.2006  /usr/lib/cernlib/2006-g77/lib/libmathlib.so.2.2006 -lnsl -lcrypt -ldl

to

cernlib =  /usr/lib/cernlib/2006-g77/lib/libpacklib.so.1.2006  /usr/lib/cernlib/2006-g77/lib/libkernlib.so.1.2006  /usr/lib/cernlib/2006-g77/lib/libmathlib.so.2.2006 -lnsl -lcrypt -ldl -lm

... But you don't use either $(mathlib) or $(LIBRARIES) anywhere else in the Makefile, so the "-lm" link flag is never used.

I'd add it too the GCC linker line:

#----- LINK ---->
sorter_GR : sorter_GR.o sorter_util.o sorter_init.o sorter_hb.o sorter_user.o sorter_read.o
         gcc $(mathlib) sorter_GR.o sorter_util.o sorter_init.o sorter_hb.o sorter_user.o sorter_read.o -lgfortran $(cernlib) -o sorter_GR

Thank Gareth Jones, leigh123linux!
I try it and make ok!
