A question for the porting net-snmp to PowerPC.
zs...@hotmail.com
Then I change the variables in makefile and libtool to my cross-compiling
tools , such as CC, AR.
//------------------------------------------------------------
makefile
CC = /LinuxPPC/CDK/bin/powerpc-linux-gcc
CPP = /LinuxPPC/CDK/bin/powerpc-linux-gcc \
-Iinclude -I$(srcdir)/include -I$(srcdir)/agent/mibgroup -I. -I$(srcdir)
\
-DDONT_INC_STRUCTS -DBINDIR=$(bindir) \
$(EXTRACPPFLAGS)
Libtool
AR="/LinuxPPC/CDK/bin/power-linux-ar"
CC="/LinuxPPC/CDK/bin/power-linux-gcc"
//-------------------------------------------------------------------
So I use “make” to compile the program. But there is an error:
//----------------------------------------------------------------------------------
making all in /mnt/diskd/net-snmp-5.1.1-for-ppc/snmplib
make[1]: Entering directory `/mnt/diskd/net-snmp-5.1.1-for-ppc/snmplib'

make[1]: *** [mib.lo] Error 1
make[1]: Leaving directory `/mnt/diskd/net-snmp-5.1.1-for-ppc/snmplib'
make: *** [subdirs] Error 1
//----------------------------------------------------------------------------------------
Then I use the libtool without change(CC=gcc, AR=ar), the result of
compiling is right. But it is obviously that the file compiled can’t be
used in my target board.
What should I do with my makefile and libtool file? Thank you very much !

You can't just change the Makefile. You need to re-run configure for the new
environment. There are some cross compiling tips here:

From the net-snmp INSTALL file:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Specifying the System Type
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D
There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on. Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=3DTYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
CPU-COMPANY-SYSTEM
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the host type.
If you are building compiler tools for cross-compiling, you can also
use the `--target=3DTYPE' option to select the type of system they will
produce code for and the `--build=3DTYPE' option to select the type of
system on which you are compiling the package.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
The most important configure options are:
--with-cc=3D[cross-compiler]
--with-ld=3D[cross-linker]
--target=3D[target-environment]
--with-endianness=3D[big|little]
Other potentially useful options:
--with-cflags=3D"..."
--with-ldlags=3D"..."
--with-ar=3D/path/ar
--enable-mini-agent
--enable-shared=3D"no"
--without-pic
Two simple examples of cross-compiling:
./configure --target=3Dppc-linux --with-cc=3Dppc_405-gcc --with-endianness=
=3Dbig
./configure --target=3Dpowerpc-snmc-linux-gnu --build=3Di386-redhat-linux \
--with-endianness=3Dbig
A more complex example involves setting environment variables for all
the flags for the tools needed for the cross compile:
export TOOLPATH=3D/opt/hardhat/devkit/ppc/405
export PATH=3D$TOOLPATH/bin:$PATH
export CFLAGS=3D' -g -fPIC -msoft-float -D_SOFT_FLOAT -Dlinux -mcpu=3D40=
3'
export CPPFLAGS=3D'-I$TOOLPATH/include -I$TOOLPATH/target/usr/include'
export ASFLAGS=3D'-g -gstabs'
export LDFLAGS=3D'-Wl,-soname,-Bdynamic -lc'=20
export LIB=3D'ar rcu'=20
./configure --build=3Di686-pc-linux-gnu --host=3Dpowerpc \
--target=3Dpowerpc-hardhat-linux-gnu --with-endianness=3Dbig
--=20

--build=i686-pc-linux-gnu --host=powerpc \

With compiling the files again, the past parse error disappeared.
But I get a new error to substitute it:
/LinuxPPC/CDK/bin/powerpc-linux-gcc -g -O2 -Dlinux -o snmpd snmpd.o

File in wrong format: failed to merge target specific data of file

collect2: ld returned 1 exit status
make[1]: *** [snmpd] Error 1
make[1]: Leaving directory `/mnt/diskd/net-snmp-5.1.1/agent'
make: *** [subdirs] Error 1
I set the big endian in the step of configuration, and I don't the cause of
the error about endianess?
Would u give me some idea of this problem?
Thank u very much!

Did you 'make distclean' before you re-ran configure? I'm guessing not.
Try 'make clean' and then another make. If that doesn't help, them 'make
distclean', re-run configure and make. If that still doesn't help, let us know
and we'll go from there.

We have done something similar and have used:
./configure \
:
:
--host=3D"powerpc-linux" \
--with-endianness=3Dbig \
:
CC=3Dpowerpc-linux-gcc \
AR=3Dpowerpc-linux-ar \
RANLIB=3Dpowerpc-linux-ranlib \
STRIP=3Dpowerpc-linux-strip \
LD=3Dpowerpc-linux-ld
ie no --build, no --target
That works for us!
PS We didn't get everything to work without specifying the tools things =
this way. I do not recall exactely what failed and which of the tools =
that are used, but it was not CC or AR that failed.
