Helloworld cross-compile error

Hi
I am trying to compile helloworld for an Overo Fire as follows: /home/rsumman/oe/tmp/cross/armv7a/arm-angstrom-linux-gnueabi/bin/gcc myHelloworld.c -o myHelloworld and in doing this the following error is thrown: gcc: error trying to exec 'cc1': execvp: No such file or directory I have read elsewhere that there is likely to be something wrong with the gcc installation if such an error occurs so I deleted /oe/tmp and did a bitbake omap3-console-image to regenerate the tmp directory, however, this didn't alleviate the problem. I am doing something stupid? Any help is appreciated Cheers Titusgroan |

Try a makefile like this (didn't try it so there is probably a typo in there, but you'll
get the idea.) ... OETMP = ~/overo-oe/tmp TOOLDIR = ${OETMP}/cross/armv7a/bin STAGEDIR = ${OETMP}/staging/armv7a-angstrom-linux-gnueabi/usr CC = ${TOOLDIR}/arm-angstrom-linux-gnueabi-gcc CFLAGS = -Wall -Wextra -Werror LIBDIR = ${STAGEDIR}/lib INCDIR = ${STAGEDIR}/include LIBS = -L ${LIBDIR} myHelloworld : myHelloworld.o ${CC} ${CFLAGS} ${OBJS} ${LIBS} -o myHelloworld myHelloworld.o: myHelloworld.c ${CC} ${CFLAGS} -I ${INCDIR} -c myHelloworld.c |

Yes this worked thanks. Another question: I need to pull in some header files from /usr/local/include/opencv and some libraries: /usr/local/lib -lm -lcv -lhighgui -lcvaux how do I do this in the makefile? I have searched online but didn't come across anything to say how to do this.
Cheers Titusgroan

You don't want the libraries from /usr/local/lib, those are binaries for your dev machine, not for an overo.
Run bitbake opencv and you'll get the opencv libraries and include files installed in your cross staging directories. You don't have to change anything in the makefile for the includes if you use the example from before. The bitbake recipe puts the libraries and includes under .../staging/.../usr/ not .../staging/.../usr/local/ like on your dev machine. For the libraries, make this change. LIBS = -L ${LIBDIR} -lm -lcv -lhighgui -lcvaux For help with compiler/linker switches in your makefile look in the gcc manual. |

Hi Sellis
I followed your instructions and things are working nicely. In addition to cross compiling code from development machine onto Overo, I have been trying to do some stuff on board. Using gcc on my Overo I tried to compile helloworld.c as follows: root@overo: /usr/bin/arm-angstrom-linux-gnueabi-gcc helloTest.c -o helloTest resulting in the following output: /usr/lib/gcc/arm-angstrom-linux-gnueabi/4.3.3/../../../crt1.o: In function `_start': init.c:(.text+0x2c): undefined reference to `__libc_csu_fini' init.c:(.text+0x34): undefined reference to `__libc_csu_init' collect2: ld returned 1 exit status any ideas about this error? Your help is much appreciated. Cheers Titusgroan

I think the following is about the minimum required to build C programs
on an Overo. make_3.81-r0.3_armv7a.ipk gcc_4.3.3-r7.1.3_armv7a.ipk gcc-symlinks_4.3.3-r7.1.3_armv7a.ipk libgmp3_4.2.4-r0.4.3_armv7a.ipk libmpfr1_2.3.1-r0.3_armv7a.ipk cpp_4.3.3-r7.1.3_armv7a.ipk cpp-symlinks_4.3.3-r7.1.3_armv7a.ipk linux-libc-headers-dev_2.6.23-r4.3_armv7a.ipk libthread-db1_2.9-r35.2.3_armv7a.ipk glibc-extra-nss_2.9-r35.2.3_armv7a.ipk libc6-dev_2.9-r35.2.3_armv7a.ipk I'd try installing these and then see what happens. |

Does anyone else have issues with opkg and installing this? When I
include 'task-native'sdk' in my recipes (based on omap3-console- image), I get opkg errors. I am building on ubuntu 9.04 if that matters.

Hey there, I've got an OVERO water that I'm trying to develop. When I attempt what you describe below using my OE implementation I get "as: unrecognized option '-meabi=4'". Am I missing some flags on the compiler? Where is that option coming from anyway?
