I build cross compilers all the time and they find libraries under the sysroot : /bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../libexec/gcc/aarch64-marvell-linux-gnu/10.1.0/collect2 -plugin /bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../libexec/gcc/aarch64-marvell-linux-gnu/10.1.0/liblto_plugin.so -plugin-opt=/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../libexec/gcc/aarch64-marvell-linux-gnu/10.1.0/lto-wrapper -plugin-opt=-fresolution=/tmp/ccp36LLm.res -plugin-opt=-pass-through=-lgcc -plugin-opt=-pass-through=-lgcc_s -plugin-opt=-pass-through=-lc -plugin-opt=-pass-through=-lgcc -plugin-opt=-pass-through=-lgcc_s --sysroot=/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root --eh-frame-hdr -dynamic-linker /lib/ld-linux-aarch64.so.1 -X -EL -maarch64linux /bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/usr/lib/../lib64/crt1.o /bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/usr/lib/../lib64/crti.o /bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc/aarch64-marvell-linux-gnu/10.1.0/crtbegin.o -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc/aarch64-marvell-linux-gnu/10.1.0 -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc/aarch64-marvell-linux-gnu/10.1.0/../../../../aarch64-marvell-linux-gnu/lib/../lib64 -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/lib/../lib64 -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/usr/lib/../lib64 -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc/aarch64-marvell-linux-gnu/10.1.0/../../../../aarch64-marvell-linux-gnu/lib -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/lib -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/usr/lib /tmp/ccDOS00V.o -lgcc --push-state --as-needed -lgcc_s --pop-state -lc -lgcc --push-state --as-needed -lgcc_s --pop-state /bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc/aarch64-marvell-linux-gnu/10.1.0/crtend.o /bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/usr/lib/../lib64/crtn.o -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc/aarch64-marvell-linux-gnu/10.1.0 -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc/aarch64-marvell-linux-gnu/10.1.0/../../../../aarch64-marvell-linux-gnu/lib/../lib64 -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/lib/../lib64 -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/usr/lib/../lib64 -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../lib/gcc/aarch64-marvell-linux-gnu/10.1.0/../../../../aarch64-marvell-linux-gnu/lib -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/lib -L/bajas/pinskia/src/toolchain-10/3b/marvell-tools/bin/../aarch64-marvell-linux-gnu/sys-root/usr/lib I configured with: Configured with: /bajas/pinskia/src/toolchain-10/scripts/../src/configure --disable-fixed-point --without-ppl --without-python --disable-werror --enable-plugins --with-lto-plugin-source=/bajas/pinskia/src/toolchain-10/scripts/../gits/gcc/lto-plugin --with-system-zlib --with-system-zstd --enable-initfini-array --disable-source-highlight --with-sysroot --with-local-prefix=/bajas/pinskia/src/toolchain-10/scripts/../marvell-tools/aarch64-marvell-linux-gnu/sys-root --disable-sim --enable-symvers=gnu --enable-__cxa_atexit --enable-symvers=gnu --enable-__cxa_atexit --disable-sim --with-multilib-list=lp64,ilp32 --enable-gnu-indirect-function --target=aarch64-marvell-linux-gnu --enable-languages=c,c++,fortran,go --prefix=/bajas/pinskia/src/toolchain-10/scripts/../marvell-tools --with-pkgversion='Marvell Inc.
