Re: [Help-glpk] ELF Library

I'm sorry, renaming the thread was my mistake.

However I successfully compiled the GLPK library in the server. Using "--prefix=PATH" with "configure" I was able to tell GLPK where to put my libraries.

But my problem is not solved. In fact gcc still can't link. 

My 5 files are: main.c define.h cplex.c cplex.h glpk.h

I use the command:

gcc -L../glpk/lib -lglpk main.c cplex.c -o proximityglpk

that gives me the linking error:

/ext/256611.1.LOW/cc84zdWg.o: In function `getintparam':

cplex.c:(.text+0x6b): undefined reference to `glp_assert_'

cplex.c:(.text+0x92): undefined reference to `glp_assert_'

/ext/256611.1.LOW/cc84zdWg.o: In function `getdblparam':

cplex.c:(.text+0x11a): undefined reference to `glp_assert_'

cplex.c:(.text+0x141): undefined reference to `glp_assert_'

etc...

Now I'm contacting the administrator of the system.

Hello Gioker

I am a little puzzled by your problem
description.  But the following thoughts
may possibly help.

That is the standard Linux format, if I am not
mistaken.  My Linux box reports, for a binary with
GLPK statically linked:

  ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux),
  statically linked, for GNU/Linux 2.6.15, not stripped

And it reports '/usr/local/lib/libglpk.a' as:

    current ar archive

GNU gcc can apparently cross-compile to
Mach-o.  See the manpage for 'gcc'.

Can you not work on your server in user space?

Else, talk to your sysadmin and get some
appropriate privileges to work on the server
as root.  Or have them do the work.

Just two other points.  Some more details about
your systems and toolchains would help.  And was
there a good reason to rename this thread, because
the earlier history is now orphaned?

HTH, Robbie
