Shell Programming and Scripting

Hello World ! ! !

I need libraries to use grib files. I only know the C language at the moment and I am working at the University under Red Hat 9.0. I downloaded the g2clib library [url=(http://www.nco.ncep.noaa.gov/pmb/docs/grib2/] (the best that I found) but I did not success to run the makefile. Here is the original file. I modified some options and paths.

# If you want to enable support for PNG or JPEG2000 encoding/decoding,
# you must specify -DUSE_PNG and/or -DUSE_JPEG2000 in the DEFS variable
# for the C pre-processor
# -DUSE_PNG requires libpng.a and libz.a
# ( and png.h pngconf.h zconf.h zlib.h include files).
# -DUSE_JPEG2000 requires libjasper.a
# ( and all the jasper/*.h include files).
#
# In addition, INC must include all directories where the above
# mentioned include files can be found.

So I tried to modify it with my little Shell Script knowledge :

Is anyone can advise me for debugging this?
Thanks

I was told to tape make in the correct directory to execute the makefile. I use Shell Script so often that I forget my little knowledges. I debug the script except the following error :

================================
Answer by the terminal after the prompt :

cc -c /home/lavigne/waves/g2lib/g2clib-1.0.2/gridtemplates.c
ar -X64 -ruv libgrib2c.a gridtemplates.o
ar: illegal option -- X
Usage: ar [emulation options] [-]{dmpqrstx}[abcfilNoPsSuvV] [member-name] [count] archive-file file...
ar -M [<mri-script]
commands:
d - delete file(s) from the archive
m[ab] - move file(s) in the archive
p - print file(s) found in the archive
q[f] - quick append file(s) to the archive
r[ab][f][u] - replace existing or insert new file(s) into the archive
t - display contents of archive
x[o] - extract file(s) from the archive
command specific modifiers:
[a] - put file(s) after [member-name]
[b] - put file(s) before [member-name] (same as [i])
[N] - use instance [count] of name
[f] - truncate inserted file names
[P] - use full path names when matching
[o] - preserve original dates
[u] - only replace files that are newer than current archive contents generic modifiers:
[c] - do not warn if the library had to be created
[s] - create an archive index (cf. ranlib)
[S] - do not build a symbol table
[v] - be verbose
[V] - display the version number
emulation options:
No emulation specific options
ar: supported targets: elf32-i386 a.out-i386-linux efi-app-ia32 elf32-little elf32-big srec symbolsrec tekhex binary ihex trad-core
make: *** [libgrib2c.a(gridtemplates.o)] Error 1

=======================

So what is going on? I do not understand. Default the ar command accepts the -X option, does not it?

do you see an 'X' in this usage?

http://publib.boulder.ibm.com/infoce...ixcmds1/ar.htm
I apologize. I do not have an IBM server (laughs)
By editing the default makefile, I find it.
So I will try to perform without -X64

I success by deleting the -X64 option. Otherwise man ar yields :
NAME
ar - create, modify, and extract from archives

SYNOPSIS
ar [-X32_64] [-]p[mod [relpos] [count]] archive [member...]

Does anyone know a good faq or informations about the libgrib2c.a ?

Thank for helping me...
