Cross compilation of openssh for ARM - linux

I am trying to cross-compile openssh for ARM.
I have suceesfully installed zlib and openssl.
I configured openssh package as following:
./configure --prefix=/usr/openssharm --host=arm -- oldincludedir=/usr/opensslarm/include --includedir=/usr/opensslarm/include --with-libs --with-zlib=/usr/zlibArm --with-ssl-dir=/usr/opensslarm --disable-etc-default-login CC=arm-linux-gnueabi-gcc AR=arm-linux-gnueabi-ar
Now when I am trying to make it, I get the following error:
arm-linux-gnueabi-ld -o ssh ssh.o readconf.o clientloop.o sshtty.o sshconnect.o sshconnect1.o sshconnect2.o mux.o roaming_common.o roaming_client.o -L. -Lopenbsd-compat/ -L/usr/opensslarm/lib -L/usr/zlibArm/lib -Wl,-z,relro -Wl,-z,now -Wl,-z,noexecstack -shared-fstack-protector-all -lssh -lopenbsd-compat -lcrypto -ldl -lutil -lz -lnsl -lresolv
arm-linux-gnueabi-ld: unrecognized option '-Wl,-z,relro'
I tried searching for the same, but could not get what the error is. I thought of modifying the LDFLAGS in the makefile but it was not useful either.
My LDFLAGS line look like:
LDFLAGS=-L. -Lopenbsd-compat/ -L/usr/opensslarm/lib -L/usr/zlibArm/lib -Wl,-z,relro -Wl,-z,now -Wl,-z,noexecstack -fstack-protector-all
What could be the possible solution of the same?

HEXAGON Halide Tools 2.3: /usr/bin/ld: cannot find -lc++abi

I did not get response from Qualcomm forum so I decided to post here. When I was trying to run examples of Halide for Hexagon by running make run as written in the document. Then I got the following issue. The -lc++abi is missing.
clang++ -std=c++11 -I /opt/qcom/Hexagon_SDK/4.3.0.0/tools/HALIDE_Tools/2.3.03/Halide/include -stdlib=libc++ -O3 -g -fno-rtti -rdynamic conv3x3_generator.cpp /opt/qcom/Hexagon_SDK/4.3.0.0/tools/HALIDE_Tools/2.3.03/Halide/lib/libHalide.a /opt/qcom/Hexagon_SDK/4.3.0.0/tools/HALIDE_Tools/2.3.03/Halide/tools/GenGen.cpp -o /opt/qcom/Hexagon_SDK/4.3.0.0/tools/HALIDE_Tools/2.3.03/Halide/Examples/build/offload/hexagon_benchmarks/bin/conv3x3.generator -lz -lrt -ldl -lpthread -lm
/usr/bin/ld: cannot find -lc++abi
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I checked the /usr/lib and find. So it should be there?
./x86_64-linux-gnu/libc++abi.so.1.0
./x86_64-linux-gnu/libc++abi.so.1
./llvm-10/lib/libc++abi.so.1.0
./llvm-10/lib/libc++abi.so.1
Did I miss anything or make anything stupid? Thanks!
ld is your system's host linker -- that's GNU BFD ld. clang++ must be in your PATH but it's the host clang++ and not the hexagon-clang++ that would be with Halide/Hexagon tools.
I contacted the person from Qualcomm. I am not supposed to use either /usr/bin/clang++ nor hexagon-clang++. I downloaded clang+llvm-7.0.1-x86_64-linux-gnu-ubuntu-18.04.tar.xz from https://releases.llvm.org/7.0.1/. You should use clang++ under the bin folder after you extract it. Now it works for me.

Use only local library with cross compiler

I'm trying to build one application with cross compiler on linux. Application is based on OpenEmbedded project. Compiler and all cross compiled libraries are located in build folder. But for one package build script is trying to use a library from my linux environment.
Command which is called from make script at the end:
/bin/sh ./arm-ABC-linux-gnueabi-libtool --tag=CXX --mode=link
arm-ABC-linux-gnueabi-g++ -march=armv7-a -mtune=cortex-a8
-mfpu=neon -mfloat-abi=softfp -g --std=c++0x -pthread -L/home/ABC/build/sysroots/armv7a-ABC-linux-gnueabi/opt/my/lib
-Wl,-rpath-link,/home/ABC/build/sysroots/armv7a-ABC-linux-gnueabi/opt/my/lib
-Wl,-O1 -Wl,--hash-style=gnu -L/opt/my/lib -o modbus_server_test modbus_server_test.o Serial.o SerialUtil.o Crc.o RtuFramer.o Pdu.o
SerialMaster.o
/home/ABC/build/sysroots/armv7a-ABC-linux-gnueabi/usr/local/apr/lib/libapr-2.la
-lcrypt -luuid -lrt -lcrypt -lpthread -ldl -lexpat -lstdc++
Most important from here that is use -lexpat flag for libexpat.so.1.5.2 library. This library is cross compiled and located in the build folder, and at the same time, we have one in my linux environment.
As result I recieve the next error:
| arm-ABC-linux-gnueabi-libtool: link:
arm-ABC-linux-gnueabi-g++ -march=armv7-a -mtune=cortex-a8
-mfpu=neon -mfloat-abi=softfp -g --std=c++0x -pthread -Wl,-rpath-link -Wl,/home/ABC/build/sysroots/armv7a-ABC-linux-gnueabi/opt/my/lib

format not recognized
| collect2: ld returned 1 exit status
| make[2]: *** [modbus_server_test] Error 1
From output I can see that it include two libraries: one from linux environment (/usr/lib/x86_64-linux-gnu/libexpat.so which is x86) and one from the build folder (build/sysroots/armv7a-ABC-linux-gnueabi/usr/lib/libexpat.so which is for ARM).At the end it complains about x86 type.
How can I exclude this library from searching in global environment? Why it even trying to use both of them?

eureka-1.11: DSO missing from command line

I was searching a lot about this type of error, but in each topic it was something different comparing to my problem.
For note: there is no configure file; also I tried to put another LDFLAGS in make file.
System: linux openSUSE Leap 42.1
The part of the makefile, if needed:
INSTALL_DIR=$(PREFIX)/share/eureka
CXXFLAGS=$(OPTIMISE) -Wall -D$(OS) \
-Iglbsp_src \
-D_THREAD_SAFE -D_REENTRANT
LDFLAGS=-L/usr/X11R6/lib
LIBS= \
-lfltk_images -lfltk_gl -lfltk \
-lX11 -lXext -lXft -lfontconfig -lXinerama \
-lpng -ljpeg -lGL -lz -lm
Any ideas how to overcome this issue?
The question can be closed - Knud Larsen has published an answer in the comment above.
All the thing was in not valid fltk on my system.
For reading the full answer to my question, see the comment, as I have already mentioned.
Thanks for help!
Testing eureka-111 with OpenSuse Leap 42.1 :
# zypper in gcc-c++ fltk-devel fltk-devel-static libXft-devel libjpeg8-devel libpng12-devel xdg-utils
cd eureka-1.11-source/ && make ... and the executable eureka is created.
P.S. : Reason for a difference with a manual build of fltk : The Suse 42.1 fltk packages were built with a different configure file ( Line 2685 edited ) :
- DSOCOMMAND="\$(CXX) \$(DSOFLAGS) -Wl,-soname,\$# \$(LDLIBS) -shared -fPIC $DEBUGFLAG -o"
+ DSOCOMMAND="\$(CXX) -Wl,--as-needed -Wl,--no-undefined \$(DSOFLAGS) -Wl,-soname,\$# \$(LDLIBS) -shared -fPIC $DEBUGFLAG -o"

Error dynamic link library in Firefox /bin/sh: symbol lookup error

I'm trying to load a library to Firefox, and I get the following error in the terminal:
http://pastebin.com/ZLryd20D,
gcc -Wall -fPIC -c 11.cpp ,
gcc -shared -o libshared.so 11.o -ldl ,
LD_PRELOAD=$PWD/libshared.so firefox ,
/bin/sh: symbol lookup error: /home/enigma/Desktop/compilacionproceso/libshared.so: undefined symbol: __gxx_personality_v0
gcc -shared -o libshared.so 11.o -ldl -lstdc++
That's the wrong solution, that happens to work on Linux by accident.
The correct command line to build your shared library is:
g++ -shared -o libshared.so 11.o
(contrary to popular belief, gcc and g++ are not the same thing).
Answer from the OP himself, taken from a revision of the question:
I solved the problem adding a flag -lstdc++ for create the library
thanks to this post
What is __gxx_personality_v0 for?
cd /directory
gcc -Wall -fPIC -c 11.cpp
gcc -shared -o libshared.so 11.o -ldl -lstdc++
LD_PRELOAD=$PWD/libshared.so program

Lacking libgdbm when installing perl

I really want to know where does this libgdbm comes from and it seems it has been in
/usr/lib/libgdbm.so.2.0.0
/usr/local/lib/libgdbm.a
/usr/local/lib/libgdbm.la
/usr/local/lib/libgdbm.so
/usr/local/lib/libgdbm.so.3
/usr/local/lib/libgdbm.so.3.0.0
, but perl says
I used the command:
cc -o try -O2 -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -fstack-protector -L/usr/local/lib try.c -lnsl -lgdbm -ldb -ldl -lm -lcrypt -lutil -lc
./try
and I got the following output:
./try: error while loading shared libraries: libgdbm.so.4: cannot open shared object file: No such file or directory
The program compiled OK, but exited with status 127.
(The supplied flags or libraries might be incorrect.)
You have a problem. Shall I abort Configure [y]
Ok. Stopping Configure.
so many files, I don't know why perl can't find any of them.
Try adding "-R/usr/local/lib" to LDFLAGS and/or CFLAGS environment variables.
If Linux perhaps change the order of searched directories in /etc/ld.so.conf
