Hi all,

I am just a newbie in cross compilation under Linux. For compiling the Openwrt flash images do I need an additional cross-compiler or toolchain to built the root and additional software ? 
I am using debian and found the following URL with cross-compilers: http://speedblue.org/cross_compilation
The OpenWRT documentation does not say anything about this issue. Compilation of the experimental.tar.bz2  with standard gcc failed because of unresolved symbols e.g  yyparse:

/usr/src/openwrt/toolchain_build_mipsel/binutils-2.15.94.0.2/binutils/ar.c:148: undefined reference to`yyparse'
collect2: ld returned 1 exit status

regards

Olaf

That error sounds like some yacc library is missing ...

hi

i have the same problem.
i installed all packages from the readme file, but still the same error.
my system is a debian sarge.
anyone an idea?

Hi,

same problem on Ubuntu 5.04... resolved by installing bison !

I'm having the same issue:

Dist: Debian
Kernel: 2.6 (and 2.4; same deal)

Packages:
dpkg -l|awk '/^ii\ *(gcc|g++|binutils|patch|bzip2|flex|bison|make|gettext|unzip|libz-dev|libc)\ / { print $2,$3 }'
binutils 2.15-7
bison 1.875d-1
bzip2 1.0.2-7
flex 2.5.31-31
gcc 4.0.0-1
gettext 0.14.5-1
make 3.80-9

End of make compile...

Anyone resolved this issue?

if you install bison later you need to remove toolchain_mipsel and rebuild from scratch.

That explains why when I started from scratch, everything worked. Thankyou very much, and also thankyou Olaf for your help.

How do you figure something like that out?

(where that = "if you install bison later you need to remove toolchain_mipsel and
rebuild from scratch - wbx")

if you have rebuild the whole buildroot 1000 times on different systems, you will recognize it
