Description Adrian Ratiu 2022-10-14 14:14:53 UTC

Hi, further testing libxcrypt in cross-compile setups has revealed the library is always compiled for the host build architecture instead of the target arch.



Reproducible: Always

Steps to Reproduce:
1. Build any cross-compiled libxcrypt
2. Run "file" on the installed binary to verify the architecture
Actual Results:  
Cross compilation builds the binary for the host architecture.

Expected Results:  
Cross compilation should build the binary for each target arch.

I've created a pull request with a fix: https://github.com/gentoo/gentoo/pull/27780

    sys-libs/libxcrypt: fix binary cross compilation
    
    Even though all files are installed in the proper places
    when cross compiling, further testing revealed the libxcrypt
    binary itself is not correctly cross-complied for the target
    architecture, instead it is compiled for the host.
    
    Set up the proper variables to ensure the binary is built for
    the correct architecture.
    
    Before:
    libcrypt.so.2.0.0: ELF 64-bit LSB shared object, x86-64,
    version 1 (SYSV), dynamically linked, BuildID[xxHash]=0d041ee2539129be, stripped
    
    After:
    libcrypt.so.2.0.0: ELF 64-bit LSB shared object, ARM aarch64,
    version 1 (SYSV), dynamically linked, BuildID[xxHash]=ba09206297aebce3, stripped
