[Linux-gpib-general] Problems compiling 3.1.2 on a Red Hat 7.2 system

[Marc L. <Mar...@un...>]

Hi,

I have been very happy to discover this week the existence of
linux-gpib.sourceforge.net. A long time ago, I had had a look at
linux-gpib (I have been using linux since 1995) but unfortunately none
of the GP-IB boards we had at that time were supported.

Recently, we have purchased GPIB-PCI card by Ines as they advertised
it to be supported under linux. Admittedly, they provide kernel
modules for linux 2.2 and 2.4, and one or two sample programs, but
without the source, and no high-level library.

Therefore, I was very happy to find out that (1) linux-gpib had been
resurrected and (2) that it supported Ines boards. I am thus currently
evaluating it.=20

However, I have some problems just compiling the stuff. I have began
fixing some things, but I would like to have some feedback.

This on a Pentium II machine running Red Hat Linux 7.2 (will all
updates applied). I usually compile my kernels, but I have found the
2.4 series a bit unresponsive, and none of the kernels I tried (up to
2.4.19-pre5) has been able to equal the performance of the Red Hat
kernels, contrary to what I was accustomed to.

Thus, I would like to stick to the latest kernel update (2.4.9-31) to
keep the platform stable once everything is in order.

What I have done :=20

1) rpm -i kernel-source.XXXX.rpm (unpacks in /usr/src/linux-2.4.9-31),=20
   cd /usr/src/linux-2.4.9-31
   modify Makefile so that EXTRAVERSION is -31
   cp configs/kernel-2.4.9-i586.config/ .config
   make oldconfig
   make dep

2) go to the freshly untarred linux-gpib-3.1.2 directory;
   make [I indicate /usr/src/linux-2.4.9-31 as the kernel source
         directory, and select the Ines driver only]=20
   compilation begins, with lots of error messages such as=20

make[2]: Entering directory `/home/lefranc/MANIP/gpib/linux-gpib-3.1.2/dr=
iver/nec7210'
gcc -I. -I../include -I../../include  -DEXPORT_SYMTAB   -c -o cmd.o cmd.c
In file included from /usr/include/linux/module.h:21,
                 from board.h:25,
                 from cmd.c:19:
/usr/include/linux/modversions.h:1:2: #error Modules should never use ker=
nel-headers system headers,
/usr/include/linux/modversions.h:2:2: #error but rather headers from an a=
ppropriate kernel-source package.
/usr/include/linux/modversions.h:3:2: #error Change -I/usr/src/linux/incl=
ude (or similar) to

uild/include
/usr/include/linux/modversions.h:5:2: #error to build against the current=
ly-running kernel.

OK. I have a look at the Makefiles in driver/* and notice that only
driver/protocol/Makefile has

INCLUDES =3D -I. -I../include -I../../include -I$(LINUXDIR)/include

, while all the others have

INCLUDES =3D -I. -I../include -I../../include

Thus, I add the -I$(LINUXDIR)/include to Makefiles in
driver/{nec7210,tms9914,sys

But then I get errors such as=20

make[2]: Entering directory `/home/lefranc/MANIP/gpib/linux-gpib-3.1.2/dr=
iver/nec7210'
gcc -I. -I../include -I../../include -I"/usr/src/linux-2.4.9-31"/include =
 -DEXPORT_SYMTAB   -c -o cmd.o cmd.c
In file included from ../include/gpib_types.h:22,
                 from ../include/gpibP.h:9,
                 from board.h:23,
                 from cmd.c:19:
/usr/include/stdint.h:37: warning: redefinition of `int8_t'
/usr/src/linux-2.4.9-31/include/linux/types.h:98: warning: `int8_t' previ=

/usr/src/linux-2.4.9-31/include/linux/types.h:100: warning: `int16_t' pre=
viously declared here

The problem here is a conflict between standard include files and
those of the kernel. SInce I have done a bit of kernel programming in
the past (writing a driver for an DAQ board), this rings a bell, and I
wonder about the absence of a -D__KERNEL__ in the CFLAGS for compiling
bits of amodule.

SInce all driver/*/Makefile have a line

CFLAGS +=3D $(INCLUDES) $(OPTIONS) -DEXPORT_SYMTAB

I add the following line in driver/Makefile

OPTIONS =3D -D__KERNEL__

(actually, I had to manually add a -D__KERNEL__ to the CFLAGS line of
driver/sys/Makefile)

With these modifications, the whole stuff seems to compile fine.=20

For installation, I had the problem that MODLIB was not defined for
whatever reason so that I had to do

make MODLIB=3D/lib/modules/2.4.9-31 install

I then get :

[...]
install  -D ines-gpib.o /lib/modules/2.4.9-31/misc/ines-gpib.o
make[2]: Leaving directory `/home/lefranc/MANIP/gpib/linux-gpib-3.1.2/dri=

Is 2.4.9 too old ?=20

Thank you very much in advance.

Marc
