I suppose you do cross compilation on x86_64 and you installed libtirpc-dev on x86_64, which does not help.

Have look at https://github.com/linux-test-project/ltp/blob/master/ci/debian.cross-compile.sh (you can run it: ARCH=aarch64 ci/debian.cross-compile.sh to solve your problem). Needed things:

dpkg --add-architecture aarch64
apt update
libtirpc-dev:aarch64

See also note about PKG_CONFIG_SYSROOT_DIR https://github.com/linux-test-project/ltp/blob/master/INSTALL#L154

fix it simplely by add --without-tirpc to configure

./configure cross_compile=$CROSS_COMPILE_NAME --host=$HOST_TARGET --target=$HOST_TARGET --prefix=$BIN_LOCATE_DIR/${testsuite} --with-realtime-testsuite --without-tirpc

[pevik]

Sure, but that's just a workaround. If you wanted to test RPC or TI-RPC, you would need what I suggested.

Hello @pevik ,

I am doing the cross compiling ltp:arm64 on debian 11 with amd64, and on debian 12 with amd64.

On debian 11 with amd64, I only install libtirpc-dev:amd64.

$ dpkg -l | grep libtirpc
ii  libtirpc-common                      1.3.1-1+deb11u1                all          transport-independent RPC library - common files                                                                                                                               
ii  libtirpc-dev:amd64                   1.3.1-1+deb11u1                amd64        transport-independent RPC library - development files                                                                                                                          
ii  libtirpc3:amd64                      1.3.1-1+deb11u1                amd64        transport-independent RPC library

On debian 12 with amd64, I only install libtirpc-dev:amd64, too.

$ dpkg -l | grep libtirpc
ii  libtirpc-common                      1.3.3+ds-1                     all          transport-independent RPC library - common files
ii  libtirpc-dev:amd64                   1.3.3+ds-1                     amd64        transport-independent RPC library - development files
ii  libtirpc3:amd64                      1.3.3+ds-1                     amd64        transport-independent RPC library

On both the debian 11, the debian 12, I perform the cross compiling by same command On debian 11 with amd64, I don't have any issue. But on debian 12 with amd64, I have issue as this issue.

On debian 12 with amd64, I add installing libtirpc:arm64 will fix this issue.

I don't know the root cause about above issue.

Question: Could you share the root cause?

Thanks, Binh.

@binhth1307 Cross-compiling is really tricky, in this case it depends on how exactly you execute the ./configure script. How exactly have you executed the ./configure script and was it exactly the same in both cases?

[binhth1307]

Thank @metan-ucw , I have executed in both cases as below:

./configure --disable-option-checking --prefix=`pwd`/output  --with-open-posix-testsuite --with-realtime-testsuite --without-perl --without-python --target=aarch64-linux-gnu --host=aarch64-linux-gnu --build=x86_64-unknown-linux-gnu build_alias=x86_64-unknown-linux-gnu host_alias=aarch64-linux-gnu target_alias=aarch64-linux-gnu CC=aarch64-linux-gnu-gcc 'CPP=aarch64-linux-gnu-gcc -E' --with-open-posix-testdir=testcases/open_posix_testsuite --cache-file=/dev/null --srcdir=.

[pevik]

Actually, nowadays we depend on PKG_CONFIG_LIBDIR (I'm not sure if LTP ever worked with --build, --host and --target triplet), see https://github.com/linux-test-project/ltp/blob/master/INSTALL#L154-L178

For aarch64 on Debian it'd be PKG_CONFIG_LIBDIR=/usr/lib/aarch64-linux-gnu/pkgconfig, for armel PKG_CONFIG_LIBDIR=/usr/lib/arm-linux-gnueabi/pkgconfig, for armhf PKG_CONFIG_LIBDIR=/usr/lib/arm-linux-gnueabihf/pkgconfig.
