This was a long standing problem seen on aarch64 build hosts when compiling python3 with clang cross compiler. The issue is not seen with gcc because native glibc headers are still compatible with gcc cross compiler (From OE-Core rev: 407744b00d702e3133304e1b43064a5634ca02cf) Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Ross Burton <ross.burton@arm.com> Cc: Jon Mason <jdmason@kudzu.us> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

Subject: [PATCH] setup.py: Do not detect multiarch paths when cross-compiling
|
|
|
|
add_multiarch_paths() function relies on host tools like dpkg-configure
|
|
to operate, which is not good when cross compiling, since it ends up
|
|
adding native paths in includes in certain cases, e.g. when building
|
|
for aarch64 targets using aarch64 build hosts running debian-like
|
|
distributions e.g. ubuntu, it ends up adding native multiarch paths
|
|
-I/usr/include/aarch64-linux-gnu during cross compile and since arches
|
|
are so similar, cross compiler (epecially clang) is inhererently configured
|
|
with multiarch ends up adding these paths to compiler cmdline which
|
|
works ok with gcc since headers are similar but clang barfs on some gcc
|
|
extentions and build fails due to missing gnu extentions but it silently
|
|
compiles when using cross gcc.
|
|
|
|
Fixes python3 cross build by not running this funciton when cross compiling
|
|
|
|
Upstream-Status: Inappropriate [OE-Specific]
