cross compiling apache-2.4.12 for arm
 

Dear all,

I am trying to cross compile Apache httpd-2.4.12 for ARM, but after solving some errors I arrived to a point where I get an error in the make process that I do not know how to solve it.

I am using apr-1.5.2, apr-util-1.5.4 and PCRE-8.37 which I copied to httpd-2.4.12/srclib/ with the names apr, apr-util and pcre.

For compile htttp I use:
The output is:

Could anyone please help me? Any suggestion suggestions?
Thanks in advance and best regards.

What host system are you using?

The host system is ubuntu 14.04 LTS

Looks like a corrupted (or wrong) version of libpthread from the error message.
Hard to tell since you didn't use code brackets around the listing, I may have misread the error message.

Hello jpollard,

I tried to reinstall libc-dev-bin 2.19-0ubuntu6.6 (Embedded GNU C Library: Development binaries) package but persists the same error. Any other suggestion?

Thank you and regards.

double check the file... It is hard to tell what the path is actually referring to:

/home/usr/CodeSourcery/Sourcery_CodeBench_Lite_for_Xilinx_GNU_Linux/bin/../arm-xilinx-linux-gnueabi/libc/lib/libpthread.so.0
