[Gumstix-users] vtun compilation problem

[Erik K. <eka...@sn...>]

Hello All,

I was wondering if someone who has seen this before, or is a little more 
experienced in troubleshooting compilation issues when adding optional 
software via buildroot might be able to send me a hint or point me in the 
right direction.

I am trying to compile vtun in the same way in which I have already 
successfully compiled tcpdump and openssh. By simply adding it as a 
TARGET+=vtun to the top level Makefile in my /gumstix-buildroot/ and running 
a make. I'm then just copying my new binaries out 
of /build_arm_nofpu/root/..., etc. And all has seemed to work well so far. 

Vtun is resisting however. This is what I am getting consistently: last 13-14 
lines right before a bomb on trying to find LZO headers.

checking for library containing socket... none required
checking for library containing inet_ntoa... none required
checking for library containing gethostbyname... none required
checking for library containing nanosleep... none required
checking for library containing setproctitle... no

checking for ZLIB Library and Header files ...
checking for deflate in -lz... yes

checking for LZO Library and Header files ...
checking for lzo1x.h... no
configure: error: LZO headers not found.
make: *** [/home/**/gumstix-buildroot/build_arm_nofpu/vtun-2.6/.configured]
Error 1
[**@** gumstix-buildroot]$

I have tried this with Revision 675, 676, and 677 (the most recent iteration 
as of right now) and I get the same exact error.

I think I have a properly compiled lzo though? If I look 
in /gumstix-buildroot/build_arm_nofpu/lzo-1.08/ and in /include in this 
directory respectively, I see lzo1x.h among other required header files.

Two things I've tried so far.

Editing the vtun Makefile to point to an lzoinclude directory that I renamed 
and copied out of /build_arm_nofpu/lzo-1.08 and placed in the staging 
directory. New config reads -> --with-lzo-headers=$(STAGING_DIR)/lzoinclude \

At which point I bomb like this --

checking for ZLIB Library and Header files ...
checking for deflate in -lz... yes

checking for LZO Library and Header files ...
checking for lzo1x.h...
(/home/**/gumstix-buildroot/build_arm_nofpu/staging_dir/lzoinclude)
yes
checking for lzo1x_decompress in -llzo... no
configure: error: LZO library not found.
make: *** [/home/**/gumstix-buildroot/build_arm_nofpu/vtun-2.6/.configured]
Error 1
[**@** gumstix-buildroot]$
  
Or I have also tried removing the requirements of lzo and openssl altogether 
from the vtun makefile since I don't need either data compression or 
encryption for vtun. But this fails as well with the same LZO headers not 
found error. I think it munges vtun way too far to try to compile it without 
those? No idea..

So those are my stabs in the dark so far. Can any one provide any tips, 
tricks, or guidance on a successful vtun install? I'm probably overlooking 
something very obvious.

Thanks!
