 Posted: Wed Jul 23, 2008 1:22 pm Post subject: cross-compiling lua for ARM |
 |
|
Hi.
I am trying to use gentoo, to crosscompile for an ARM platform. For this, I use crossdev on my pentium 4 PC, and follow the steps indicated in the embedded handbook.
The thing is that when I execute xmerge lua, the process runs OK, but makes the compilation for the x86, instead of the ARM.
I can see in the output that libtool is called with gcc as the compiler argument, instead of being called with arm-linux-gnu-gcc, that is, the cross compiler. I think this argument is taken from the environment variable CC, but although I set it manually before calling xmerge, it does not change anything.
I have set the following environment variables (among others):
| Code: | CBUILD=i686-pc-linux-gnu
CC=arm-linux-gnu-gcc
CHOST=arm-linux-gnu
|
This is the output I get:
| Code: | crossdev # xmerge -v lua
These are the packages that would be merged, in order:
Calculating dependencies... done!

Hi,
as I faced similar issues during a glib MIPS crosscompile there might be some thing to look out for:
Check the build directory | Quote: | | /var/tmp/portage/dev-lang/lua-5.1.1-r2/work/lua-5.1.1 ... |
if there is a local copy if libtool.
Removing it can help or install a cross libtool and link to the cross libtool can help too.
regards |

Sorry for my ignorance, but I can not look for that directory, as it is deleted on emerge completion. Any way to avoid deleting the temporary directory?
I do think I have installed a cross libtool, as I have been able to compile ncurses, and I have libs for arm under my /usr/arm-linux-gnu/lib directory. How can I now if emerge is linking to the right libraries?
Thank you very much |
