Clion Cmake 静态库链接 -static-libgcc -static-libstdc++

Question

I'm using centos 8 Gcc

Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/8/lto-wrapper
OFFLOAD_TARGET_NAMES=nvptx-none
OFFLOAD_TARGET_DEFAULT=1
Target: x86_64-redhat-linux
Configured with: ../configure --enable-bootstrap --enable-languages=c,c++,fortran,lto --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-shared --enable-threads=posix --enable-checking=release --enable-multilib --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-gcc-major-version-only --with-linker-hash-style=gnu --enable-plugin --enable-initfini-array --with-isl --disable-libmpx --enable-offload-targets=nvptx-none --without-cuda-driver --enable-gnu-indirect-function --enable-cet --with-tune=generic --with-arch_32=x86-64 --build=x86_64-redhat-linux

My CMake [UPDATED]

cmake_minimum_required(VERSION 3.10)
project(TestProject)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_FLAGS " -static -static-libgcc -static-libstdc++ -std=c++17")
add_executable(TestProject main.cpp)
SET(BUILD_SHARED_LIBS OFF)

#--------------- Static Includes -----------------
set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)
set(PHTREADS_LIB "-lphreads")
#----- Include Curl
set(CURL_LIBRARY "-lcurl")
find_package(CURL REQUIRED)
include_directories(${CURL_INCLUDE_DIR})

target_link_libraries(TestProject ${CURL_LIBRARIES}  ${PHTREADS_LIB})

The issue [UPDATED

/usr/bin/ld: cannot find -lcurl
/usr/bin/ld: cannot find -lphreads
/usr/bin/ld: cannot find -lm
/usr/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status
gmake[3]: *** [CMakeFiles/TestProject.dir/build.make:84: TestProject] Error 1
gmake[2]: *** [CMakeFiles/Makefile2:68: CMakeFiles/TestProject.dir/all] Error 2
gmake[1]: *** [CMakeFiles/Makefile2:80: CMakeFiles/TestProject.dir/rule] Error 2

My main goal is to try to add (libgcc libstdc++) as static.

Can someone guide me on what I'm doing wrong?

Answer 1

/usr/bin/ld: cannot find -lm
/usr/bin/ld: cannot find -lc

Missing glibc-static

Centos 8

dnf --enablerepo=PowerTools install glibc-static
or
yum install glibc-static

for libstdc++

dnf --enablerepo=PowerTools install libstdc++-static
or 
yum install libstdc++-static

Centos 7

yum install glibc-static

Include Threads

#----- Include phtread
find_package(Threads REQUIRED)
target_link_libraries(${PROJECT_NAME} Threads::Threads)

Include Curl [FIX]

Here is more complicated for Centos 8

Zlib

dnf --enablerepo=PowerTools install zlib-static

CMake Include Zlib

add_library(
        libz
        STATIC IMPORTED
)
set_target_properties(
        libz
        PROPERTIES IMPORTED_LOCATION
        /usr/lib64/libz.a
)

Install Static Lib

wget https://curl.haxx.se/download/curl-7.61.0.tar.gz

tar -xvf curl-7.61.0.tar.gz

cd curl-7.61.0/

Set Config

./configure --disable-debug --disable-ftp --disable-ldap --disable-ldaps --disable-rtsp --disable-proxy --disable-dict --disable-telnet --disable-tftp --disable-pop3 --disable-imap --disable-smb --disable-smtp --disable-gopher --disable-manual --disable-ipv6 --disable-sspi --disable-crypto-auth --disable-ntlm-wb --disable-tls-srp --without-nghttp2 --without-libidn2 --without-libssh2 --without-brotli --with-zlib --without-ssl

for SSL ( --with-ssl  required openssl-static (not availabe for Centos 8 ) ) 

Install

make && make install

Cmake Changes

add_library(
        libz
        STATIC IMPORTED
)
set_target_properties(
        libz
        PROPERTIES IMPORTED_LOCATION
        /usr/lib64/libz.a
)
