Trouble with g++ & libpqxx lib - g++

I've very simple example, and can't correctly build it, I was using next arguments:
g++ -lpq -libpqxx -Wall -o "pg" "pg.cpp" (in dir: /home/user)
/usr/lib/gcc/i586-suse-linux/4.5/../../../../i586-suse-linux/bin/ld: cannot find -lpq
collect2: ld returned 1 exit status
or
returned 1 exit status g++ -libpqxx -Wall -o "pg" "pg.cpp"
(in dir: /home/user)
/usr/lib/gcc/i586-suse-linux/4.5/../../../../i586-suse-linux/bin/ld:
cannot find -libpqxx collect2: ld
but everywere had error.
libpqxx succ installed
#lisuse-home:~> locate libpqxx | grep /lib/
/usr/lib/libpqxx-3.1.so
/usr/lib/libpqxx.la
/usr/lib/libpqxx.so
/usr/lib/pkgconfig/libpqxx.pc

g++ filename.cpp -o target -lpqxx
-lpqxx should take care of -lpq. If for some reason it does not find pq, find pq and put it in the same directory as pqxx.

compiling g++ -libpqxx-3.1 -Wall -c "%f"
building g++ -Wall -o "%e" /usr/lib/libpqxx-3.1.so "%f"

cmake error when building a C library as BPF

I would like to use a rust library that is a C bindings in Solana.
First Solana is calling the cmake of the h3 library, I am replicating the process here.
I am cloning the repo and creating a build folder
git clone --recurse-submodules https://github.com/nmandery/h3ron.git
mkdir h3ron/build
cd h3ron/build
I export the path to lld and run the cmake command very similar to solana's command (I added -v -fuse-ld=lld ) why is solana missing this one argument? it seems it needs solana's lld and not the system ld.
export PATH="/home/pc/.local/share/solana/install/releases/1.9.4/solana-release/bin/sdk/bpf/dependencies/bpf-tools/llvm/bin/:$PATH"
"cmake" "../h3ron-h3-sys/libh3" \
"-DCMAKE_INSTALL_PREFIX=./h3ron-h3-sys-df478ba73015eab9/out" \
"-DCMAKE_C_FLAGS= -ffunction-sections -fdata-sections -fPIC --target=bpfel-unknown-none -v -fuse-ld=lld" \
"-DCMAKE_C_COMPILER=/home/pc/.local/share/solana/install/releases/1.9.4/solana-release/bin/sdk/bpf/dependencies/bpf-tools/llvm/bin/clang" \
"-DCMAKE_CXX_FLAGS= -ffunction-sections -fdata-sections -fPIC -v" \
"-DCMAKE_CXX_COMPILER=/usr/bin/c++" \
"-DCMAKE_ASM_FLAGS= -ffunction-sections -fdata-sections -fPIC --target=bpfel-unknown-unknown -v" \

"-DCMAKE_BUILD_TYPE=Release"
The error:
Target: bpfel-unknown-none
Thread model: posix
InstalledDir: /home/pc/.local/share/solana/install/releases/1.9.4/solana-release/bin/sdk/bpf/dependencies/bpf-tools/llvm/bin

ld.lld: error: CMakeFiles/cmTC_26933.dir/testCCompiler.c.o is incompatible with elf64-x86-64
collect2: error: ld returned 1 exit status
Note: The system ld would generate this error /usr/bin/ld: unknown architecture of input file CMakeFiles/cmTC_5c450.dir/testCCompiler.c.o' is incompatible with i386:x86-64 output
any idea?

g++ error: Cannot specify -static with -fsanitize=address

I am trying to use address sanitizer with g++ and during the build it produces the following linker command, which produces the error g++: error: cannot specify -static with -fsanitize=address
I don't understand what this means, so any help is appreciated. The g++ version is g++ (GCC) 8.3.0 20190222 (Cray Inc.).
g++ -g -fsanitize=address CMakeFiles/pisa.dir/src/Alphabet.cpp.o {more .o files} -o pisa -L/global/homes/e/esaliya/sali/git/bitbucket/combinatorial-blas-2.0/CombBLAS/_install/lib -Wl,-rpath,/global/homes/e/esaliya/sali/git/bitbucket/combinatorial-blas-2.0/CombBLAS/_install/lib -lCombBLAS -lGraphGenlib -lUsortlib

Percona5.7 cmake failed on centos 7

I get the source code of percona-server from github. And I install boost 1.59 and gcc gcc-c ncurses-devel. I enter the directory of percona-server and run "cmake --DWITH_BOOST=/data/boost" but get the following error. I cannot find some solution so I came to here. Thanks!!

it seems you haven't all needed dependencies installed.
These are the steps which are needed:
sudo yum install epel-release
sudo yum install git gcc gcc-c++ openssl check cmake bison boost-devel asio-devel
libaio-devel ncurses-devel readline-devel pam-devel wget perl-Env time numactl-devel
rpmdevtools rpm-build curl-devel
git clone https://github.com/percona/percona-server.git
cd percona-server
git submodule init
git submodule update
cmake . -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<PATCH_TO_BOOST_DIR>
Then boost will be downloaded automatically

handmade Makefile to Cmake with static library

Here is a MakeFile for my project, since I'm using CLion for as my IDE, I need a Cmake configuration. I could not convert the following Makefile correctly.
all: VisualCryptography

Where am I doing wrong?
This is the error that I'm getting:
/usr/bin/ld: cannot find -lVC
collect2: error: ld returned 1 exit status
CMakeFiles/VC.dir/build.make:172: recipe for target 'VC' failed

make[1]: *** [CMakeFiles/VC.dir/rule] Error 2
Makefile:118: recipe for target 'VC' failed
make: *** [VC] Error 2
I also should note that the libVC.a is in lib sub dir of my project, and all other source codes are in source sub dir. the main function is also in libVC.a, which is static.
Try changing the name as oLen suggested, this behavior is seen in some versions of Cmake. You can check another version if you insist on using the same name.

Link errors while using G++ for MPI code

My code is as simple as this:
#include <mpi.h>
int main(int argc, char**args) {
MPI_Init(&argc, &args);
int mpiSize;
int mpiRank;
MPI_Comm_size(MPI_COMM_WORLD, &mpiSize);
MPI_Comm_rank(MPI_COMM_WORLD, &mpiRank);
MPI_Finalize();
}
I first compile it to object file:
g++ -c src/mpitest.cpp -o src/mpitest.o
Then I can easily use mpicxx:
mpicxx src/mpitest.o -o mpi
But I want to use g++ instead, because It's easier for automake, so I tried:
mpicxx src/mpitest.o -o mpi -show
It prints out:
g++ src/mpitest.o -o mpi -I/usr/local/include -L/usr/local/lib -L/usr/local/lib -lmpichcxx -lmpich -lopa -lpthread -lrt
And yes, that command actually does the same thing successfully. However, If I tried to change it to (I just change the object file and output to the end):
g++ -I/usr/local/include -L/usr/local/lib -L/usr/local/lib -lmpichcxx -lmpich -lopa -lpthread -lrt src/mpitest.o -o mpi
Which is what automake does when it adds LDFLAGS, the g++ start complaining...
src/mpitest.o: In function `main':
..src/mpitest.cpp:5: undefined reference to `MPI_Init'
../src/mpitest.cpp:8: undefined reference to `MPI_Comm_size'
../src/mpitest.cpp:9: undefined reference to `MPI_Comm_rank'
../src/mpitest.cpp:10: undefined reference to `MPI_Finalize'
collect2: ld returned 1 exit status
What happens with g++ ? I couldn't figure out. Please enlighten me. Why the order here matter at all ? What is the proper way to do what I want from the beginning ?
Thanks a lot
p/s : g++ --version
g++ (Ubuntu 4.4.3-4ubuntu5) 4.4.3
mpi is mvapich2
I didn't really remember, maybe since version 4, library to link with -l must be passed after all source and object files.
