1 week ago Doesn't look right. Where is
libintl.so.8and why it is needed?
Because my OpenWrt build is NLS enabled (CONFIG_BUILD_NLS), libintl.so.8 is located in here :
/home/user/works/openwrt/staging_dir/target-x86_64_glibc_custom/usr/lib/libintl-full/lib
or
$(STAGING_DIR)/usr/lib/libintl-full/libThe build.rs for libbpf uses
LD_LIBRARY_PATHhttps://github.com/libbpf/libbpf-sys/blob/master/build.rs#L188C36-L188C51
The compilation is failing at einat not libbpf
root@buildsystem:/home/user/works/openwrt# ldd /home/user/works/openwrt/staging_dir/target-x86_64_glibc_custom/usr/lib/libelf.so
linux-vdso.so.1 (0x00007ffd965f1000)
libintl.so.8 => not found
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f146c828000)

/lib64/ld-linux-x86-64.so.2 (0x00007f146c872000)These below are only workaround that i have tried in other to make rustc able to pickup libintl.so.8 but still not being picked up with rustc
TARGET_CFLAGS += -Xlinker -rpath=$(STAGING_DIR)/usr/lib/libintl-full/lib
or
TARGET_LDFLAGS += -L$(STAGING_DIR)/usr/lib/libintl-full/lib -lintl
or
export LD_LIBRARY_PATH=$(STAGING_DIR)/usr/lib/libintl-full/libyou may try your luck using RUSTFLAGS for that purpose. I guess we could add those search paths in a central config.toml if it solves your problem.

1 week ago I did have tried using RUSTFLAGS but still not picked up with rustc, that's why it's weird.
Based on here :
RUSTFLAGS += "-C linker-flag=-Wl,-rpath-link,$(STAGING_DIR)/usr/lib/libintl-full/lib"in dl/cargo/config.toml I have tried the following :
[target.x86_64-unknown-linux-gnu]
linker = "x86_64-openwrt-linux-gnu-gcc"
rustflags = ["-L", "/home/user/works/openwrt/staging_dir/target-x86_64_glibc_custom/usr/lib/libintl-full/lib"]
rustc-link-search = { all = "/home/user/works/openwrt/staging_dir/target-x86_64_glibc_custom/usr/lib/libintl-full/lib" }but still not picked up with rustc
If you have time, you could try to reproduce this issue by enabling CONFIG_BUILD_NLS and glibc.

1 week ago @lu-zero I thought that it was libelf issue, after i have tried to patchelf the libelf with the location of libintl.so.8 but still errror out, this might be OpenWrt's rust build process issue ?.
I have tried to include the following to einat build.rs and "rpath = true" to einat's Cargo.toml :
println!("cargo:rustc-link-lib=dylib=libintl.so.8");
println!("cargo:rustc-link-search=native=/home/user/works/openwrt/staging_dir/target-x86_64_glibc_custom/usr/lib/libintl-full/lib");
println!("cargo:rustc-link-arg=-Wl,-rpath,/home/user/works/openwrt/staging_dir/target-x86_64_glibc_custom/usr/lib/libintl-full/lib");But still rustc seems to ignore it

1 week ago The order should be the opposite, I think.
Check what's the rustc final invocation passing -v to cargo

1 week ago That's why i said rustc seems ignoring everything that we are sets to cargo or Cargo.toml or config.toml or env variables.
Please try it yourself, it's einat , and with CONFIG_BUILD_NLS enabled.
It's also happening on musl & CONFIG_BUILD_NLS enabled.

1 week ago Hi, I am the author of https://github.com/EHfive/einat-ebpf.
I think there is some misunderstanding going on here.
So both einat and its build script link against libelf, the dependency path for the former is einat -> libbpf(-sys) -> libelf.so, and it's "build script of einat" -> libbpf-cargo -> libbpf(-sys) -> libelf.so for the latter.
As you can see, einat does not use libintl, it's just dynamically linked by libelf, so the issue is not really on einat or cargo/rustc.
The main problem here is both ld and ld-linux.so cannot find libintl.so used by libelf.so. In the case of ld, it has caused ld to report the unresolved symbol error due to ld 's default --unresolved-symbols=report policy. And in the case of ld-linux.so, it would cause binary linked with libelf thus indirectly using libintl fail to execute.
What need to addressed is why libintl has not been setup properly so both ld or ld-linux.so can locate it? Could it be rpath to libintl was not set properly in libelf? Or is there some misconfiguration in Rust build process? Note I am just guessing here as I know little about OpenWrt build system.
Another minor issue here is einat's build script is linking with target build of libelf instead of host build of libelf(in tools or build machine?).

1 week ago I guess part of the problem is that host and target are the same x86_64 to add additional confusion to the issue ...

You mean in openwrt-einat-ebpf's Makefile? But einat does not link to libintl or use its symbols.

I tryied, still failed.

And in fact $(INTL_DEPENDS) has been depended on by libelf, and there is no need to depend on it again in einat.

5 days ago Noticed that there is a commented
# RUSTC_LDFLAGS+= -C link-args=$(INTL_LDFLAGS)line in @muink 's openwrt-einat-ebpf dev branch. RUSTC_LDFLAGS would eventually be included into RUSTFLAGS, so it seems right at first glance.
However INTL_LDFLAGS has more than one link flags separated with space, so only the first flag in INTL_LDFLAGS would be passed as link-args.
The following change should make openwrt-einat-ebpf built again with CONFIG_BUILD_NLS for musl target.
RUSTC_LDFLAGS+= $(foreach arg,$(INTL_LDFLAGS),-C link-arg=$(arg))
# or
RUSTC_LDFLAGS+= -C link-arg=-L$(INTL_PREFIX)/lib -C link-arg=-Wl,-rpath-link=$(INTL_PREFIX)/libThe following also works as rustc would pass proper link flags for libintl it found to linker(via cc -Wl).
RUSTC_LDFLAGS+= -L$(INTL_PREFIX)/lib -lintleinat has build script depends on host libelf, and that build script would build target binary that depends on target libelf.
@vortexilation build openwrt-einat-ebpf for x86_64-unknown-linux-gnu target on x86_64-unknown-linux-gnu host. So Cargo would link to target libelf due to share of x86_64-unknown-linux-gnu triple on host and target. And due to Cargo's lack of host and target separation for build script, https://github.com/rust-lang/cargo/issues/4423 , there is no graceful way to handle this case.
This means the libintl searching error would also happens on compilation of build script if host triple and target triple are same.
I guess passing the flags above can also make the build script built. However RUSTFLAGS only apply to compilation of target object as CARGO_BUILD_TARGET is specified, this requires patching rust-values.mk to use CARGO_TARGET_<TARGET>_RUSTFLAGS instead so these flags can also apply to compilation of build script. See also https://doc.rust-lang.org/cargo/reference/config.html#buildrustflags .

I did not test this part as I am using musl SDK and I don't want to spend times for compiling of glibc toolchain builds.

To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.@muink
Are you sure haven't forgot to re-enable "CONFIG_BUILD_NLS" ?. Haven't tried with musl but glibc still error on me.

5 days ago @vortexilation You didn't read my previous comment carefully, right? Especially the second section.
And you are not even trying to read logs from yourself or changes in @muink 's commit. As if you read, you would know that error is for build script instead if einat target binary, and @muink 's commit only covers the first change mentioned in my comment that only fixes building for musl target.
... built again with CONFIG_BUILD_NLS for musl target.
... share of x86_64-unknown-linux-gnu triple on host and target. This means the libintl searing error would also happens on build script if host triple and target triple are same.
Question yourself before question someone else next time.

5 days ago @EHfive I have had already read my logs or @muink changes, but maybe because typos and gotten the hypes up of @muink's succeed.

I have already previously tried adding CARGO_TARGET_x86_64_UNKNOWN_LINUX_GNU_RUSTFLAGS="-C link-args=-Wl,-rpath,$(STAGING_DIR)/usr/lib/libintl-full/lib" into rust-values.mk but it was seems getting no differences.
Let me retry it now with your exact changes as snippet above. Recompiling rust now for OpenWrt.
In Makefile, i just need to do the following ? :
CARGO_RUSTFLAGS += -C link-args=-Wl,-rpath,$(STAGING_DIR)/usr/lib/libintl-full/lib[EDIT] Rust recompiled, with snippet above being applied and added these to Makefile :
RUSTC_LDFLAGS += $(foreach arg,$(INTL_LDFLAGS),-C link-arg=$(arg))
CARGO_RUSTFLAGS += -C link-args=-Wl,-rpath,$(STAGING_DIR)/usr/lib/libintl-full/libBut still the same errror.

Description:
I wanted to compile einat , but somehow rustc cannot found libintl at the end.
I have tried everything
but rustc still didn't picked it up.
