Using -I/usr/include during the crosstool-ng build of libstdc++ pulled in host x86_64 headers where int64_t is long long, contaminating the aarch64 cross-build where int64_t should be long. This caused linker errors for std::__atomic_futex_unsigned_base symbols due to mismatched C++ name mangling between headers and the built library. Copy only the required sys/sdt.h headers into /opt/ct-ng-includes and point CT_CC_GCC_ENABLE_CXX_FLAGS there instead, matching the approach used by manylinux_2_28-aarch64.

# Common Docker instructions to install "crosstool-ng" and build a full
|
|
# cross-compiler suite from a crosstool-ng configuration, CROSSTOOL_CONFIG.
|
|
#
|
|
# This import complements the "dockcross/base" image, adding:
|
|
# - "ct-ng", a cross-compiler building utilty.
|
|
# - A cross-compiler suite configured in "crosstool-ng.config".
|
|
#
|
|
# The generated cross-compiler will have a CROSS_ROOT of:
|
|
# ${XCC_PREFIX}/${CROSS_TRIPLE}
|
|
#
|
|
# A given platform will need to supply the appropriate "crosstool-ng.config" to
|
|
# generate its cross-compiler. This can be built using "ct-ng menuconfig" to
|
|
# generate a configuration.
