$CC Statically compiled applications

[lixuhui112]

hello everyone:

     I want to use meta-toolchain Statically compiled applications ,but I encountered some problems

Ｉuse

arm-linux-gnueabi-gcc -o hello hello.c -static

is ok ,but I use

source /opt/poky/1.7/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

$CC -o hello hello.c -static

/opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.9.1/ld: cannot find -lc

collect2: error: ld returned 1 exit status

Are meta-toolchain missing static library? And how can I build SDK it contains the static library

Next time, please check and raise such kind of questions to Yocto forum.

Here is the link of Yocto document.

Yocto Project Application Developer's Guide

Note

By default, this toolchain does not build static binaries. If you want to use the toolchain to build these types of libraries, you need to be sure your image has the appropriate static development libraries. Use the IMAGE_INSTALL variable inside your local.conf file to install the appropriate library packages. Following is an example using glibc static development libraries:      IMAGE_INSTALL_append = " glibc-staticdev"

Ｉ　add IMAGE_INSTALL_append = " glibc-staticdev" in build-x11/conf/local.config,and rebuild meta-toolchain

$ bitbake meta-toolchain

and install the SDK , but  I use

source /opt/poky/1.7/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

$CC -o hello hello.c -static

/opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.9.1/ld: cannot find -lc

collect2: error: ld returned 1 exit status

it also return the same error

We have done the test and listed below.

As suggest before, please check and raise such kind of questions to Yocto forum.
